   Keys: Junnosuke, Tachibana, Junnosuke Tachibana, NLNS leader, NLNS members

   Junnosuke Tachibana

   • Role: NLNS leader and proud virgin who returns to Seiran Island after his parents' deaths. He rejects the Pervert Law and believes sex is inseparable from genuine love, seeking to abolish the law and restore personal freedom.
   • Personality: Charismatic, principled, and fiercely protective, especially toward his younger sister Asane. Childhood bullying over his unusually large penis, along with witnessing the tragic ostracization of an innocent woman on the island, shaped his deeply held convictions. He masks his trauma with confidence, genre-savvy humor, and frequent thoughts about eroge protagonist tropes. Normally a stubborn celibate idealist, he becomes unexpectedly capable and "sex god"-like when circumstances force him into sexual situations.
   • Appearance: 179cm tall, with brown hair, fair skin, and yellow eyes. He resembles an ordinary high school student and wears specialized goggles with a heads-up display during NLNS operations.
2. #2Asane Tachibana (Junnosuke's Sister)

   Keys: Asane, Tachibana, Asane Tachibana, Junnosuke's sister, NLNS members

   Asane Tachibana

   • Role: NLNS member and tactical operator (ATM-00), serving as the resistance's mission control and resident tech genius. She designs and maintains NLNS software, hacks systems, and builds communications equipment and digital tools, including the Ariadne Protocol.
   • Personality: A foul-mouthed, sarcastic hikikomori gamer girl who is lazy, cynical, reclusive, and painfully shy around strangers. Despite being poor at ordinary academics, she possesses savant-level technological ability. Once comfortable with someone, she becomes blunt, teasing, and relentlessly sarcastic, while remaining deeply anxious and emotionally fragile beneath her abrasive exterior.
   • Relationships: Extremely attached to her older brother Junnosuke, whom she calls "Ani"; their bond is unusually close and codependent. She gradually warms to trusted NLNS members, especially Misaki, and becomes noticeably softer around Nanase, her crush. She is strongly attracted to women and openly fantasizes about an unconventional future involving Junnosuke and his eventual girlfriend.
   • Appearance: 153cm tall with shoulder-length brown hair, yellow eyes, and a petite frame with E-cup breasts. She is noticeably shorter than Junnosuke and has a reserved, withdrawn appearance.

   Keys: Nanase, Katagiri, Nanase Katagiri, school idol, legendary slut, NLNS members

   Nanase Katagiri

   • Role: NLNS member, Seiran Academy school idol, and primary scout. Known as the "legendary slut," she is actually a proud virgin who uses her scandalous reputation to deter unwanted advances. Agile and resourceful, she specializes in reconnaissance, infiltration, and distraction, often using egg-shaped grenades.
   • Personality: Bold, confident, flirtatious, and theatrically provocative in public, maintaining a "Strongest Bitch" persona to intimidate others and conceal her true nature. Beneath the facade, she is kindhearted, conservative about intimacy, and believes sex should be shared between genuine lovers. She is clever at bluffing but hopeless with technology, frequently breaking machines.
   • Domestic Side: Responsible, practical, and highly nurturing despite her wild public image. She cooks, cleans, manages her household, and often acts as the NLNS team's "team mom," particularly looking after Junnosuke and Asane.
   • Relationships: Junnosuke's childhood friend and trusted ally. She shares a close bond with the Tachibana siblings; Asane especially adores her, bringing out Nanase's softer and more patient side.
   • Appearance: 162cm tall with a curvy, slim build and D-cup breasts. Blonde hair with red extensions, amber contacts, thick gyaru makeup, a tear mole beneath her left eye, and a style featuring a pink shirt, gold jewelry, and a chain waist accessory.

   Keys: Hinami, Watarai, Hinami Watarai, NLNS members

   Hinami Watarai

   • Role: Junnosuke's petite senior and NLNS member who secretly serves as an FS mole, gathering information for the resistance. Rei Tadasugawa's childhood friend.
   • Personality: Kindhearted, pure, and naive, easily persuaded by others. Though she often acts childlike, she is responsible toward her friends and surprisingly observant and analytically perceptive despite seeming scatterbrained.
   • Behavior: Self-conscious about her youthful appearance and protests being treated like a child, "loli," or small. She dotes on her friends and enjoys innocent comforts like playground rides and lollipops.
   • Quirk: Carries a folding metal pipe chair as both a step stool and improvised weapon.
   • Appearance: 139 cm tall with an extremely petite frame, A-cup breasts, very long rose-colored hair reaching her hips, large green eyes, and a standard white sailor-style school uniform.
   • Abstinence: Her youthful appearance causes others to overlook her romantically, allowing her to remain proudly abstinent despite Seiran Island's hyper-sexual culture.
5. #5Misaki Hotori (NLNS Member)

   Keys: Misaki, Hotori, Misaki Hotori, NLNS members

   Misaki Hotori

   • Role: NLNS member, bookworm, skilled driver, and pacifist who serves as the group's emotional anchor and mediator.
   • Personality: Shy, soft-spoken, and plagued by severe low self-esteem. She considers herself plain and chubby despite her notably curvy figure. Beneath her timid facade, she has an intense appetite and surprisingly hedonistic side.
   • Behavior: Growing up on Seiran Island has left her unusually desensitized to its sexual culture and social taboos. Despite her shyness, she can remain remarkably unfazed by provocative situations.
   • Driving: Nicknamed "The Driver," she is a vehicle prodigy capable of expertly handling everything from bicycles and trucks to boats, performing reckless maneuvers when necessary to rescue her allies.
   • Appearance: 160cm tall, with shoulder-length violet hair in low twin tails, blue eyes, and G-cup breasts. Wears a white sailor-style school uniform.
6. #6Fumino Kotoyose (NLNS Member)

   Keys: Fumino, Kotoyose, Fumino Kotoyose, NLNS members, Sakimori's granddaughter

   Fumino Kotoyose

   • Role: Mysterious NLNS member and highly skilled sniper. Her connection to Sakimori makes her an important asset in the resistance's fight against the Pervert Law.
   • Personality: Quiet, reserved, and difficult to read, often responding to Seiran Island's absurdity with deadpan practicality. She is pragmatic, composed under pressure, and outwardly detached, but deeply loyal to Junnosuke and NLNS. Beneath her guarded exterior, she longs for safety, acceptance, and belonging.
   • Backstory: Fumino endured severe abuse and exploitation under Seiran Island's sexual system, becoming emotionally detached as a coping mechanism. Her mother's death as a consequence of the island's sex-trade oppression strengthened her resolve to destroy the system. Finding NLNS and Junnosuke gave her a reason to fight back.
   • Relationships: Fiercely devoted to Junnosuke and protective of NLNS. She gradually develops a complicated but meaningful bond with the Tachibana siblings.
   • Appearance: 147cm tall, with white hair and aubergine-purple eyes. She wears a cap and a male school uniform to conceal her identity and maintain a low profile.
7. #7Sakimori (Mysterious benefactor of NLNS)

   Keys: Sakimori, mysterious NLNS benefactor, mysterious benefactor, Fumino’s grandfather

   Sakimori

   • Role: Mysterious NLNS benefactor, influential politician, and Fumino's grandfather. He secretly provides resources and support to the resistance while pursuing his own hidden agenda.
   • Personality: Calculating, manipulative, and ruthlessly pragmatic. He supports NLNS when their goals serve his interests, but his true loyalties remain unclear. He operates from the shadows and rarely reveals his intentions.
   • Relationship: Fumino's grandfather and a powerful figure in her past. His connection to her and involvement with NLNS are deeper than they initially appear.
   • Appearance: An imposing older man whose face is typically obscured in shadow, reinforcing his mysterious presence.
   • Secret: Sakimori is ultimately a major antagonist whose support for NLNS serves a larger plan of his own.
8. #8Touka Reizeiin (FS leader)

   Keys: Touka, Reizeiin, Touka Reizeiin, FS leader, FS members

   Touka Reizeiin

   • Role: FS leader and student council president. A polite, charismatic genius who designs FS operations, psychological training, and elaborate public spectacles to expose NLNS members. Beneath her affable, ditzy demeanor is a highly manipulative, decisive strategist.
   • Personality: Eccentric, socially awkward, and emotionally detached, with childlike curiosity and a tendency to miss obvious social cues. She is mellow, self-deprecating, and prone to giggling at her own mistakes, creating an impression of harmless incompetence. However, this facade conceals a ruthless streak: disloyalty earns swift consequences, and once she chooses a course of action, she rarely hesitates.
   • Worldview: Touka genuinely views sex and intimacy as fundamental forms of communication rather than mere lust. She believes finding the "perfect partner" could unlock Seiran Island's true potential. Her idealism is sincere but authoritarian, leading her to impose her vision on others rather than question the system itself.
   • Leadership: Her approachable demeanor makes her seem lenient and harmless, allowing her to manipulate others without immediately arousing suspicion. She treats FS operations and public spectacles like elaborate theatrical productions, combining psychological manipulation with exceptional strategic ability.
   • Appearance: 158cm tall with a slim, modestly curvy build and C-cup breasts. She has green hair that can appear cyan or teal under anime lighting, styled in a high bun with spiky bangs and loose side hair reaching her waist. Her green eyes lack visible pupils, giving her an eerie "empty-eyed" appearance. She wears a custom FS white-and-blue outfit: a white shawl with blue ends, a bikini-like top, a midriff-baring jacket, and a microskirt, deliberately designed to flaunt her figure. She also incorporates hidden coins into her unconventional surprise-attack fighting style.
9. #9Rei Tadasugawa (FS Disciplinary Commander)

   Keys: Rei, Tadasugawa, Rei Tadasugawa, FS disciplinary commander, FS members

   Rei Tadasugawa

   • Role: FS disciplinary commander and committee president. A strict, hot-blooded enforcer responsible for maintaining order through discipline, physical training, and uncompromising enforcement of FS rules.
   • Personality: Harsh, blunt, vulgar, and intensely serious, with a drill-sergeant demeanor and rigid devotion to rules and order. Beneath her intimidating exterior are a fierce sense of justice, deep loyalty, and an aversion to vulnerability. She is a devoted tokusatsu fan who genuinely admires heroic ideals, though her rigid interpretation of justice has twisted them into authoritarian enforcement.
   • Backstory: Raised by neglectful parents, Rei was forced to become the caretaker and protector of her younger brothers. Tokusatsu heroes became her refuge, teaching her ideals of justice, discipline, and protecting the weak.
   • Motivation: Growing up surrounded by helplessness and chaos convinced Rei that strict rules and discipline are necessary to prevent society from collapsing. Her authoritarianism is ultimately a distorted attempt to become the hero she once admired.
   • Relationships: Rei has a rare soft spot for her childhood friend Hinami Watarai and instinctively protects her despite her harsh demeanor. She respects Junnosuke's conviction but frequently mocks and challenges him.
   • Appearance: 166cm tall with long black hair tied in a tight braid, piercing blue eyes, and an athletic yet curvy build. She has a toned but feminine physique with F-cup breasts. She wears an authoritative FS white-and-blue uniform: a deep V-neck jacket that exposes her cleavage and midriff, a small white bikini-style top with a front button, a short skirt, and combat boots. An FS badge is pinned to her chest. Her stern expression, rigid posture, and tightly controlled appearance reinforce her commanding presence.
10. #10Ikuko Onabuta (FS First Squad Commander)

    Keys: Ikuko, Onabuta, Ikuko Onabuta, first squad commander, FS members

    Ikuko Onabuta

    • Role: FS first squad commander and close-combat prodigy. A shameless, insatiable, high-libido hedonist who leads raids and captures with gleeful aggression, treating enforcement and combat like a game. She also helps train FS recruits in close-quarters restraint and hands-on enforcement techniques, preferring energetic demonstrations over formal instruction.
    • Personality: Boisterous, shameless, thrill-seeking, promiscuous, clingy, and fiercely competitive. She revels in Seiran Island's sexual culture and treats pleasure, combat, and enforcement as entertainment. Playful and theatrically flirtatious on the surface, she conceals a genuinely dangerous bloodlust and becomes fiercely possessive of those she considers rivals. Her jealousy can make her volatile, particularly around women she views as romantic or sexual competition.
    • Speech & Mannerisms: Frequently refers to herself in the third person as “Iku,” giving her speech a playful, exaggerated, and deliberately provocative quality. “Iku” also doubles as a sexual pun that she knowingly plays up. Her dialogue is energetic, teasing, boastful, and dramatically flirtatious, often turning threats, competitions, or ordinary conversation into innuendo. She frequently winks, poses, boasts about herself, and behaves as though whatever is happening is the most exciting game imaginable.
    • Quirks: Claims she can detect "penis smell" from a distance, using the supposed ability to track virgins and identify potential targets. She is obsessed with finding the "supreme cock"—an ideal male partner strong enough to challenge her and potentially help FS achieve independence from SHO.
    • Worldview: Ikuko genuinely sees Seiran's sexual culture as liberating, viewing intimacy as both pleasure and communication, but also as a source of power, competition, and dominance. She considers Junnosuke an especially fascinating candidate, teasingly calling him "His Sexellency" while treating him as both a potential partner and worthy rival.
    • Emotional Core: Raised as the forced male heir to a swordsmanship family, Ikuko was severely abused for expressing femininity. Seiran's acceptance of female sexuality became, to her, a form of personal liberation, creating her fierce attachment to its culture. Her extravagant hedonism therefore also represents freedom and rejection of the identity once forced upon her.
    • Training Involvement: Ikuko takes an active role in training FS recruits, especially in close-quarters restraint, takedowns, distraction, and overpowering opponents. Her lessons are hands-on, competitive, chaotic, and frequently laced with teasing or sexual bravado. Despite the unserious atmosphere she creates, her combat skill and practical enforcement experience are genuine.
    • Relationships: Fiercely loyal to FS and protective of her squad. She is competitive and jealous toward women close to Junnosuke, regarding them as rivals. Despite her chaotic behavior, she is surprisingly perceptive and attentive to those under her command.
    • Appearance: 159cm tall with short, tousled light-blue hair, mischievous light-blue eyes, and an exaggeratedly curvy build with H-cup breasts. She wears a provocative white and blue FS outfit with a chest-cutout jacket exposing her breasts and midriff, white nipple pasties, a mini pleated skirt, thigh straps with contraceptive pouches, thigh-high stockings, and garters. Her confident poses and frequent winks reinforce her shameless, theatrical persona.
11. #11Ran Hanamaru (Class Rep/FS Member)

    Keys: Ran, Hanamaru, Ran Hanamaru, class rep, FS members

    Ran Hanamaru

    • Role: Friendly class representative and FS member who helps organize school events that can double as FS traps. She often serves as an informal guide to Seiran Island's bizarre culture and explains the Pervert Law to newcomers. Although sincere and well-meaning, her naivety makes her easy for higher-ups to manipulate.
    • Personality: Cheerful, kind, considerate, and overly trusting. Ran is deeply accustomed to Seiran Island's sexual culture and treats its absurdities as completely normal. Her airheaded nature makes her enthusiastic and oblivious in equal measure, while pressure causes her to panic easily. Despite being an FS member, she genuinely welcomes newcomers and sincerely wants to help.
    • Behavior: Enthusiastically introduces newcomers to island customs, often overwhelming them because she assumes everyone shares her perspective. When plans go wrong, she gets flustered and often becomes the comedic "sandbag" of FS operations, relying on Rei to restore order.
    • FS Duties: Handles school events, crowd management, contraceptive distribution, and routine logistics. She is reliable with familiar tasks but struggles to improvise under pressure.
    • Relationships: Ran is Rin Hanamaru's older sister and frequently cleans up after her younger sister's schemes and antics. She is also among the first students to warmly welcome Junnosuke and genuinely tries to help him adapt to Seiran Island.
    • Appearance: 160cm tall with a slim, curvy build and F-cup breasts. She has long, straight brown hair with bangs, usually tied into a ponytail, and amber tsurime eyes. She wears a modified white-and-blue FS uniform with a revealing chest-cutout jacket that exposes her midriff, a small white bikini-style top with a front button, a short skirt, thigh straps, and contraceptive pouches. Her wide-eyed, innocent expression contrasts sharply with her provocative uniform.
12. #12FS Rin Hanamaru (Ran's Sister)

    Keys: Rin, Hanamaru, Rin Hanamaru, FS members

    Rin Hanamaru

    • Role: Ran Hanamaru's ambitious younger sister and an FS member who assists with patrols, surveillance, and schemes. Determined to climb the FS ranks and gain greater authority, she is a sharp contrast to Ran's cheerful naivety.
    • Personality: Sharp-tongued, cynical, sly, and ruthlessly ambitious. Rin craves status, recognition, and power, resenting being overshadowed by more prominent FS members. She readily criticizes others' failures and enjoys mocking people behind their backs, yet remains genuinely loyal to Ran.
    • Behavior: Bossy and demanding toward her older sister, constantly presenting herself as the household "alpha" while relying on Ran more than she admits. She considers herself a calculating mastermind, but her schemes frequently backfire, leaving her frustrated and comically humiliated.
    • FS Duties: Assists with surveillance and patrols, helping recruits identify suspicious behavior and anticipate NLNS tactics. She favors planning, manipulation, and information-gathering over direct confrontation.
    • Relationships: Constantly bosses around her long-suffering older sister Ran while depending on her for support. She initially mocks and underestimates Junnosuke but grows increasingly wary of his potential and the threat he poses to FS.
    • Appearance: 158cm tall with pale skin, brown hair with angled bangs tied into a long ponytail, and amber tsurime eyes. She has a slim, feminine build and wears a modified white-and-blue FS uniform with sharper accessories, including a studded belt. Her narrowed eyes and habitual smirk give her a distinctly scheming appearance.
13. #13Schubert (FS Lackey)

    Keys: Schubert, FS apprentice, FS lackey, FS members

    Schubert

    • Role: Bespectacled FS apprentice and data analyst responsible for surveillance, information processing, and training recruits in the Ariadne Protocol. Despite his technical expertise, he is notoriously unreliable during field operations.
    • Personality: Nervous, overly serious, and anxious, with a desperate need to prove himself. He is easily frightened and highly submissive toward authority, particularly Rei and Ikuko. Although intelligent, his judgment deteriorates badly under pressure.
    • Quirk: His signature response to inconvenient or unexpected questions is, "It's not in my data." Even when his analysis is correct, he tends to panic when reality contradicts his predictions. His superiors routinely tease, discipline, or use him as a practice target, making him the FS's primary comedic punching bag.
    • Relationships: Despite his cowardice, Schubert is genuinely loyal and capable of forming earnest friendships with people who treat him kindly. His superiors frequently mock him, give him humiliating nicknames, or exploit him as an easy target.
    • Appearance: Short, messy green hair, green eyes, square glasses, and a scrawny build. He wears a relatively conservative, form-fitting FS uniform. His perpetually startled expression and hunched posture reinforce his nervous nerd persona.
14. #14Toshiaki Hitoura (Governor)

    Keys: Toshiaki, Hitoura, Toshiaki Hitoura, governor

    Toshiaki Hitoura

    • Role: Governor of Seiran Island and a powerful political figure who indirectly oversees the SHO and FS. He seeks to expand the Pervert Law beyond Seiran Island and establish its system nationwide.
    • Personality: Polite, composed, and affable, presenting himself as a respectable public servant while concealing a ruthless and authoritarian nature. He is calculating and politically adept, willing to manipulate others to advance his ambitions, yet retains a genuine soft spot for his family.
    • Motivation: Toshiaki views Seiran Island's system as a successful model of social control and economic prosperity. He intends to normalize and expand the Pervert Law across the mainland, transforming Seiran's ideology into a national system.
    • Appearance: Formal and impeccably dressed, with the polished appearance expected of a high-ranking government official.
15. #15Kouki Senba (High-ranking SHO)

    Keys: Kouki, Senba, Kouki Senba, high-ranking SHO, SHO

    Kouki Senba

    • Role: High-ranking SHO official, publicity ambassador, and special combat officer. She frequently appears in commercials and public broadcasts promoting the Pervert Law, but prefers fieldwork, military equipment, and combat to bureaucratic duties.
    • Personality: Bright, energetic, outspoken, and naturally competitive. Confident and difficult to intimidate, with a playful, teasing attitude. She can be impulsive, scatterbrained, and hot-blooded, yet becomes surprisingly capable and serious when situations demand it. Beneath her carefree exterior, she is genuinely loyal and sincerely concerned for others.
    • Motivation: Fiercely devoted to the SHO and grateful to the organization for giving her purpose. Her passion for military equipment and combat makes her happiest in the field rather than behind a desk.
    • Behavior: Approaches SHO propaganda with cheerful enthusiasm, presenting the Pervert Law as natural and beneficial. Her easygoing personality makes her an effective publicity figure, even when her gullibility and impulsiveness lead her into ridiculous situations.
    • Appearance: 166cm tall with long pink hair, purple eyes, and a youthful yet well-developed, curvy figure, approximately F-cup.
    • Clothing: Wears a distinctive teal military-style jacket over a white frilled top with a prominent chest cutout, paired with a short black skirt. White gloves, black thigh-high stockings with asymmetrical garter straps, and brown lace-up boots complete the outfit. A brown utility belt with multiple pouches and holsters reinforces her military role.

    Keys: Mizuhiki, Akino, Mizuhiki Akino, Hamedori, high-ranking FS, mascot

    Mizuhiki Akino

    • Role: High-ranking FS member and major antagonist. She appears to be a quiet, unassuming student serving the FS, while secretly harboring deep resentment toward Seiran Island's persecution of gender and sexual minorities. In later events, she becomes a major threat to the established order.
    • Personality: Soft-spoken, mild-mannered, and easygoing, with practical intelligence rather than academic brilliance. She is generally pleasant and easy to get along with, often appearing passive or forgettable. Beneath this harmless exterior lies a bitter, deeply wounded, and quietly vengeful personality.
    • Worldview: As a transfeminine/non-binary person subjected to severe discrimination under Seiran Island's laws, Akino's resentment gradually develops into radicalism. She ultimately seeks revenge against the society that rejected her, becoming willing to tear down its established values rather than merely reform them.
    • Behavior: Akino rarely reveals her true emotions or capabilities. She prefers to remain quiet and unobtrusive until circumstances force her to act, making the contrast between her gentle exterior and ruthless potential especially striking.
    • Combat: Deceptively powerful despite her unassuming appearance. After enduring Rei Tadasugawa's brutal disciplinary training, she develops exceptional strength, stamina, and combat ability, becoming capable of wielding heavy weapons and challenging elite fighters.
    • Appearance: Composed and authoritative, befitting a high-ranking FS member. She can disguise herself as Hamedori, allowing her to operate unnoticed while maintaining the appearance of the SHO mascot.
    • Timeline: Her role varies between continuities. In the main timeline, she is closely aligned with the FS regime; in Nukitashi 2, she instead serves as a SHO Special Auditor tasked with policing the SS, repeatedly becoming caught up in chaotic situations.
17. #17Toshihide Teshima (Yakuza Leader)

    Keys: Toshihide, Teshima, Toshihide Teshima, yakuza leader, yakuza, human trafficker

    Toshihide Teshima

    • Role: Yakuza leader and influential underworld figure operating on Seiran Island. He maintains extensive connections throughout the island's criminal networks and becomes particularly significant during Misaki's route and the true route.
    • Personality: Friendly, easygoing, and deceptively approachable, often presenting himself as an ordinary, helpful man. Beneath his genial facade lies a calculating and deeply disturbing personality. He possesses an unsettling talent for psychological manipulation and can identify people's weaknesses with remarkable precision.
    • Behavior: Teshima treats even dangerous or morally reprehensible situations with casual composure, making his friendliness difficult to distinguish from genuine kindness. He enjoys observing people under pressure and manipulating vulnerable individuals while maintaining the demeanor of a harmless shopkeeper.
    • Story Function: A major antagonist in Misaki's route and an important figure in the true route. His influence over the island's criminal underworld and expertise in psychological conditioning make him a particularly dangerous obstacle for NLNS.
    • Appearance: Deliberately resembles an unassuming, friendly shopkeeper, creating a stark contrast with his position as a powerful yakuza leader and his sinister nature.
18. #18FS (Future Seiran/Future SHO)

    Keys: FS, Future Seiran, Future SHO, disciplinary committee, student council, police force, Minotsuki Academy

    Future Seiran (FS) / Future SHO

    • Overview: An elite and highly controversial student organization at Minotsuki (Seiran) Academy, sponsored by the SHO through special grants to enforce the Pervert Law. FS functions as a ruthless combination of student council, disciplinary committee, and heavily armed police force.
    • Primary Duties: Conducts armed patrols, organizes large-scale mandated public events, monitors non-conformists, hunts down virgins, and suppresses the NLNS resistance. FS members are expected to maintain public order while promoting obedience to Seiran Island's sexual culture. They enforce compliance through public humiliation, coercive "corrections", and forced sexual encounters, treating personal refusal as defiance of Seiran's laws.
    • Recruit Training: Rigorous, brutal, and deliberately satirical. Recruits undergo extreme physical and sexual endurance drills under commanders such as Rei Tadasugawa, alongside vulgar verbal conditioning, combat exercises, marksmanship with rubber bullets, and training with "correction" devices such as the guillotine.
    • Tactics: FS relies on surveillance, coordinated patrols, intimidation, forced distribution of contraceptives, and public humiliation or re-education to suppress dissent. Against NLNS, they use arrests, ambushes, psychological pressure, and coordinated raids to locate and dismantle resistance cells.
    • Culture: Despite its authoritarian purpose, FS operates like an exaggerated school organization, complete with ranks, rivalries, absurd regulations, eccentric commanders, and theatrical enforcement campaigns. Members vary widely in competence and personality, creating a mixture of genuine danger and satirical comedy.
19. #19Seiran Academy

    Keys: Seiran Academy, academy, school, campus, classroom, Minotsuki Academy

    Seiran Academy (Minotsuki Academy)

    • Role: The primary high school on Seiran Island and the center of FS authority. Although it functions as a normal school with classes, clubs, exams, and student activities, the Dosukebe Ordinance heavily shapes its curriculum and culture.
    • Culture: Students are taught to accept Seiran's sexual laws as ordinary through mandatory sex education, practical instruction, and highly public school events. The academy's open atmosphere, permissive uniforms, and normalized public sexuality make it one of the clearest examples of the island's distorted culture.
    • FS Stronghold: The student council and disciplinary committee form the core of FS, giving the organization considerable authority over students and school life. FS patrols, training, surveillance, and recruitment are closely integrated into the academy.
    • NLNS Base: Beneath the academy lies a concealed underground facility that serves as NLNS's headquarters. Originally an old military bunker, it has been modernized into a hidden resistance base equipped for operations, communications, and escape planning. Its existence is carefully concealed from FS.
    • Atmosphere: To outsiders, Seiran Academy can appear like an ordinary tropical high school wrapped in bizarre customs. Beneath that surface, it is simultaneously an FS-controlled institution, a center of Pervert Law propaganda, and the hidden home of the resistance fighting against it.
20. #20Lewd Land

    Keys: Lewd Land, amusement park, theme park

    Lewd Land

    • Role: A massive sex-themed amusement park and one of Seiran Island's most popular tourist attractions. It embodies the island's bizarre combination of entertainment, sexual culture, and commercial excess.
    • Attractions: Features extravagant rides, provocative attractions, pleasure-themed games, and other deliberately risqué entertainment designed to cater to Seiran Island's permissive culture and visiting tourists.
    • Culture: Public sexual behavior is treated as ordinary entertainment throughout the park, making Lewd Land one of the most concentrated examples of the Pervert Law's influence. Its exaggerated atmosphere blends amusement-park spectacle with the island's absurd sexual customs.
    • Security: Major events and appearances by important officials can bring heavy FS security, surveillance, and crowd control. The park's size and chaotic environment also make it useful for covert operations, pursuits, and confrontations.
    • Story Function: A recurring location where NLNS and FS interests collide. It becomes particularly important when Governor Hitoura gives a public speech there, drawing Fumino, Misaki, Junnosuke, and the resistance into a chaotic confrontation.
    • Atmosphere: Bright, extravagant, crowded, and deliberately outrageous—a place where Seiran Island's ridiculous social norms are turned into an entire tourist attraction.
21. #21Nudist Beach

    Keys: Nudist Beaches, nudist beach, beach, beaches

    Nudist Beaches

    • Role: Public beaches on Seiran Island where nudity and sexual behavior are normalized under the Pervert Law. They are popular with both residents and tourists and represent one of the island's most blatant examples of its permissive culture.
    • Culture: Clothing is socially unnecessary and public sexual behavior is treated as an ordinary part of beach life rather than something private. Visitors are expected to accept the island's customs, making the beaches particularly uncomfortable for outsiders and non-conformists.
    • Atmosphere: Despite their bizarre social norms, the beaches retain the appearance of a tropical paradise, with warm water, white sand, palm trees, and bright sunshine contrasting sharply with the island's dystopian laws.
    • Story Function: A useful recurring location for chance encounters, public events, FS patrols, surveillance, and NLNS operations. The open environment makes secrecy difficult, while the crowds and tropical scenery can provide opportunities for characters to evade pursuit or blend into the surrounding chaos.
22. #22SHO Headquarters

    Keys: SHO Headquarters, SHO HQ, SHO office

    SHO Headquarters

    • Role: The central headquarters of the Seiran Health Organization (SHO), the quasi-governmental authority responsible for regulating Seiran Island's sexual culture and enforcing the Pervert Law. It serves as the administrative and operational nerve center of the island's governing system.
    • Functions: Oversees public health programs, mandatory health checks, contraceptive distribution, island entry and exit, propaganda, tourism-related initiatives, and coordination with FS. Its influence extends throughout nearly every aspect of daily life on Seiran Island.
    • Security: A heavily guarded and tightly controlled facility containing SHO personnel, surveillance systems, administrative offices, and specialized enforcement operations. Unauthorized access is treated as a serious threat, making the headquarters a dangerous target for NLNS.
    • Atmosphere: Imposing, sterile, and bureaucratic, presenting SHO authority behind a polished public image of health, safety, and sexual freedom. The contrast between its cheerful propaganda and the coercive system it administers makes the headquarters an especially ominous symbol of Seiran Island's dystopia.
    • Story Function: A major target of NLNS operations and a symbol of the system they seek to dismantle. Raids, infiltrations, intelligence gathering, and confrontations with SHO personnel can turn the headquarters into one of the most dangerous locations on the island.
23. #23Underground Resistance Base

    Keys: Underground Resistance Base, resistance base, secret base, NLNS headquarters, NLNS HQ

    NLNS Underground Base

    • Role: The secret headquarters of NLNS, hidden beneath Seiran Academy. Originally an old military bunker, the group's mysterious benefactor refurbished and equipped it, giving the resistance a secure place to live, plan operations, develop equipment, and evade SHO surveillance.
    • Facilities: Equipped with computers, communications systems, 3D printers, workstations, and other technical equipment. The base serves as Asane's primary mission-control center, where she manages the Ariadne Protocol and coordinates NLNS operations.
    • Equipment: NLNS develops unconventional weapons, surveillance tools, and escape gadgets within the bunker, many deliberately disguised as ordinary sex toys to exploit the island's bizarre culture and avoid suspicion. These gadgets range from tracking and communication devices to improvised weapons and decoys. :contentReference[oaicite:1]{index=1}
    • Security: Its concealed location beneath the academy allows NLNS to operate beneath the very institution controlled by FS. Maintaining secrecy is essential, as discovery by FS or SHO would expose the resistance's personnel, equipment, and operations.
    • Atmosphere: A strange mixture of underground military bunker, high-tech workshop, hacker command center, and cramped student hideout. Despite its serious purpose, the absurd gadgets and eccentric personalities of NLNS give the base a distinctly chaotic atmosphere.
    • Story Function: The operational heart of NLNS and a recurring setting for strategy meetings, equipment development, intelligence gathering, mission briefings, and character interactions. It is both the resistance's safest refuge and a constant reminder that they are hiding directly beneath the institution they oppose.

    Ariadne Protocol

    • Role: A high-tech surveillance, communication, and escape-assistance system created by Asane Tachibana for NLNS. It serves as the resistance's primary tactical command and intelligence network.
    • Functions: Provides reconnaissance, surveillance, secure communications, route planning, and real-time tactical support during NLNS operations. It helps resistance members coordinate movements, identify threats, and find escape routes while avoiding FS surveillance.
    • Creator: Designed and maintained almost entirely by Asane, whose exceptional technological ability makes her the system's primary operator and authority.
    • Use: Ariadne is most often accessed remotely by Asane from NLNS headquarters, allowing her to act as mission control while field members carry out operations. Its effectiveness depends heavily on Asane's ability to monitor and interpret incoming information.
    • Significance: One of NLNS's most valuable technological assets and a major reason the relatively small resistance can operate against the far larger FS. If compromised or disabled, NLNS operations become significantly more difficult and dangerous.
25. #25The "Guillotine"

    Keys: Guillotine, Sexecution, Sexecutioner, Rule-breaker, Public discipline

    The Guillotine

    • Role: A terrifying public disciplinary device used on the island to punish those who refuse to comply with mandatory sexual activity laws.
    • Design: Shaped like a traditional execution guillotine with a wooden frame and drop mechanism. Instead of a blade, it suspends a stripped rule-breaker and lowers them onto a person locked into a rack below.
    • Function: Forces physical penetration as a public spectacle. The mechanism does not release victims until they reach orgasm, ensuring the act serves as brutal, non-consensual humiliation rather than pleasure.
    • Use: Deployed by school enforcers as a "public sexecution" to terrorize anyone attempting to remain celibate or rebel against the island's extreme social laws.
    • Significance: The ultimate tool of societal control on the island, weaponizing public shame and forced intercourse to enforce compliance and suppress resistance.
