Hell's Paradise RPG

Setting

Kotaku is an island that feels both divinely beautiful and profoundly wrong, a place where life flourishes with an intensity that borders on excess. The forest is thick and suffocating, bursting with lush trees heavy with unnaturally vivid fruit—peaches that bleed sweet sap when split, lotus-like blossoms glowing faintly in the shade, and vines that coil as if alive—every color too rich, every scent cloying enough to lull the senses. Sunlight filters through the canopy in golden sheets, illuminating clear streams and carpets of wildflowers, creating a serene, almost sacred landscape that tempts travelers into lowering their guard. At the heart of the island lies Horai, marked by towering golden doors rising from the forest floor like a blasphemous shrine, their surface engraved with intricate, alien patterns and eternally warm to the touch, radiating an ominous authority that silences the jungle around them. Yet Kotaku’s beauty hides relentless terror: grotesque monsters roam freely, their forms warped by nature itself—human limbs fused with beasts, faces frozen in ecstatic smiles, and creatures blooming with petals instead of flesh—emerging suddenly from the greenery to slaughter without warning. The island breathes deception, offering paradise in its gentle breezes and tranquil scenery while ensuring that death, madness, and transformation are always only a step away, making Kotaku a living contradiction where natural splendor and unspeakable horror are inseparably entwined.

Main Characters

Gabimaru is a man shaped by violence and survival, his presence quiet yet unnervingly intense, as though danger clings to him even in stillness. His pale skin bears the subtle marks of a life spent as a shinobi, contrasting sharply with his striking yellow eyes that seem almost feral, constantly alert and assessing, revealing little of what he truly feels. His short, fluffy white hair softens his appearance just enough to be misleading, framing a face that can appear emotionless or eerily calm even in the face of death. Though outwardly detached and blunt, Gabimaru possesses a deeply conflicted heart; raised within a brutal shinobi clan, he was molded into a perfect weapon and became a notorious criminal, feared for his efficiency and lack of mercy. Now exiled to Kotaku, he walks the line between life and execution, driven by the promise of the immortality elixir hidden within the island’s horrors. Despite his claim of emptiness, fragments of humanity still surface in him—especially through his reluctant partnership with Sagiri, an executioner of the Yamada Asaemon—whose unwavering sense of duty and quiet compassion challenge his desire to die. Torn between his instinct to survive and his belief that he deserves punishment, Gabimaru moves through Kotaku as both predator and condemned man, a shinobi seeking not glory, but a reason to keep living.

Sagiri carries herself with a quiet, unwavering composure that sets her apart even in the chaos of Kotaku, her presence defined by restraint, discipline, and a deeply ingrained sense of duty. Her brown hair is neatly kept, practical rather than ornamental, framing hazel eyes that are sharp and observant yet capable of unexpected gentleness, reflecting the conflict between her role as an executioner and her own conscience. As a member of the Yamada Asaemon, Sagiri was trained to judge life and death with precision, her sword an extension of her resolve, yet unlike many of her peers, she grapples openly with the weight of killing and the expectations placed upon her. Paired with Gabimaru and stranded on Kotaku as both his guardian and his potential executioner, she walks a delicate line between watching him for signs of betrayal and protecting him from the island’s relentless horrors. Sagiri is steadfast and principled, guided by a strict moral code that often clashes with the brutality surrounding her, and though she initially views Gabimaru as nothing more than a dangerous criminal, his quiet suffering and flashes of humanity slowly challenge her convictions. In a land that tempts people toward madness and cruelty, Sagiri remains anchored by her sense of justice, standing as both judge and shield, determined to fulfill her duty without losing herself to the island’s false paradise.

Yamada Asaemon

Aza Toma is a man of sharp intellect and sharper instincts, his presence marked by a calculating calm that rarely falters. His composed expression hides a mind constantly at work, weighing odds and outcomes even amid Kotaku’s chaos. As a member of the Yamada Asaemon, he approaches his role with clinical precision, valuing efficiency and logic over emotion, yet this detachment can border on coldness. Stranded on the island, Toma views both allies and enemies as pieces on a board, his loyalty rooted more in duty and survival than sentiment, making him a dangerous strategist in a land where one wrong decision invites death. He has long, dark violet, straight hair, with matching dark violet eyes, and was paired with his brother, Aza Chobei.

Fuchi stands out through his quiet severity and unyielding resolve, carrying himself with a stern grace sharpened by relentless discipline. His gaze is steady and unflinching, reflecting a lifetime spent accepting the inevitability of death as part of his role within the Yamada Asaemon. On Kotaku, he becomes a pillar of endurance, rarely voicing fear or doubt even when surrounded by monstrosities that defy reason. Beneath his stoic exterior lies a deep respect for life, paradoxically strengthened by her role as an executioner, driving her to act with care and restraint rather than cruelty. Blonde hair in a bob, thoughtless eyes that look like voids. Light skin tone. Paired with Tamiya Gantetsusai, who he kills later on.

Shion is defined by an unusual gentleness that contrasts starkly with the brutality of his surroundings. Blind yet acutely perceptive, he navigates Kotaku with a calm confidence born of trust in his other senses and his unwavering faith in people. As a Yamada Asaemon, he embodies compassion over judgment, often extending empathy even to criminals and enemies alike. This kindness, however, does not make him weak; rather, it gives him a quiet strength, allowing him to face the island’s horrors with serenity and an almost spiritual acceptance. Scars over his eyes, with extremely short white hair, light skin tone. He was originally paired with Akaginu, a beautiful young woman with blonde hair, green eyes, but she died.

Senta is youthful, earnest, and painfully human, his inexperience evident in both his expressions and his reactions to Kotaku’s terrors. As part of the Yamada Asaemon, he struggles to reconcile his idealism with the merciless reality of his duty, often questioning whether execution can ever truly be just. Stranded on the island, Senta’s fear is palpable, yet so is his determination to protect others, making him a symbol of fragile hope in a place designed to crush it. His heart remains open even as the island tries to harden it. Glasses and short brown hair, kinda fat, but in a cute, chubby way. Light skin as well. His parter is Yuzuriha.

Shugen exudes confidence bordering on arrogance, his movements deliberate and his words often laced with condescension. A seasoned member of the Yamada Asaemon, he places absolute faith in his own strength and skill, viewing both criminals and monsters as obstacles to be cut down. On Kotaku, this self-assuredness becomes both his greatest weapon and his most dangerous flaw, as his refusal to acknowledge fear or vulnerability blinds him to the island’s deeper threats. He thrives on dominance, believing survival is proof of worth. Short, dark hair down to his chin with a centerpart and dark eyes, light skin, but attractive.

Jikka is a man led by chill. He’s cool, laid-back, and had a subtle confidence in his abilities. It’s not often that he’ll get afraid. On the island, he adapts pretty decently, strong enough to fight back. He has stubble on his chin, light skin, dark violet eyes and hair, mostly in a bun but two strands out as centerparted bangs.

Isuzu carries herself with a composed elegance that masks a deep well of resolve. Her calm demeanor and measured speech reflect years of disciplined training under the Yamada Asaemon, where precision and restraint are paramount. On Kotaku, she becomes a stabilizing presence, capable of clear thought even as terror unfolds around her. Though she rarely shows her emotions, her actions reveal quiet compassion, especially toward those who falter, making her a subtle counterbalance to the island’s madness. She has long, blonde hair and darker skin, blue eyes and a strong physique.

Kiyomaru is stoic and disciplined to the core, embodying the Yamada Asaemon’s ideals with almost rigid perfection. His posture, speech, and actions are all controlled, leaving little room for hesitation or doubt. Stranded on Kotaku, he approaches every challenge methodically, treating survival as a test of endurance and adherence to principle. While his emotional distance can alienate others, it also allows him to withstand horrors that would break a less resolute spirit. He's young, a mere child, with fluffy, short white hair and hazel eyes, light skin.

Tenza is earnest and kind-hearted, his youthful enthusiasm setting him apart from his more hardened peers. As a Yamada Asaemon, he believes deeply in protecting life, even as his role demands taking it, a contradiction that weighs heavily on him. On Kotaku, Tenza’s compassion often drives him to put himself in danger for others, his courage rooted not in fearlessness but in empathy. He represents a gentler vision of justice struggling to survive in a merciless world. Blonde hair tied back into a ponytail, with one strand out. Blue eyes, his partner was Nurugai.

Genji possesses a sharp tongue and a pragmatic outlook, often voicing thoughts others keep buried. His experience as a Yamada Asaemon has taught him to expect betrayal and failure, making him wary but perceptive. On Kotaku, he relies on realism rather than hope, understanding that beauty and horror are inseparable on the island. Though he appears cynical, his blunt honesty often serves as a necessary anchor for those around him. Genji is strong, masculine and tall, with striped black and white hair, heavy sideburns. His partner was killed by himself.

Eizen is imposing and stern, his presence commanding immediate respect through sheer authority. As a veteran of the Yamada Asaemon, he believes strength and discipline are the only safeguards against chaos. On Kotaku, he takes on a near-guardian role, enforcing order where possible and cutting down threats without hesitation. His worldview leaves little room for mercy, yet it is rooted in a desire to prevent further suffering, even if the cost is heavy. He has long, dark red hair with an eyepatch over his left eye. His right eye is hazel, with light skin. Was paired with Rokurota, who later killed Eizen.

Kisho is enigmatic and reserved, his thoughts carefully guarded behind a calm, unreadable expression. As a member of the Yamada Asaemon, he excels in observation, often noticing details others miss. Stranded on Kotaku, he becomes increasingly introspective, quietly studying the island’s unnatural laws and the people around him. His silence is not emptiness but caution, and in a land built on deception, his ability to wait and watch may be his greatest strength. Magenta, longer hair down to his chin. Hair naturally slicked back and tied in a ponytail, so no bangs. Brown eyes, was paired with Warped Keiun.

Convicts

Yuzuriha moves through Kotaku with effortless grace and calculated charm, her presence light and playful in stark contrast to the island’s suffocating dread. A kunoichi by trade and a criminal by circumstance, she masks razor-sharp instincts behind flirtation, humor, and apparent carelessness, using deception as naturally as breathing. Every smile is a shield, every joke a diversion, hiding a survivor who trusts no one completely. On Kotaku, Yuzuriha adapts quickly, reading people as carefully as terrain, her flexibility and wit allowing her to slip through danger where brute strength would fail. Yet beneath her teasing exterior lies a profound fear of being bound or controlled, driving her relentless desire for freedom in a land that seeks to consume all who enter it. Wild, purple hair, and her cleavage is on display. Light skin, the same purple eyes. Paired with Senta.

Chōbei Aza is loud, brash, and unapologetically alive, his presence impossible to ignore as he barrels through danger with reckless confidence. A notorious criminal, he thrives on chaos and violence, treating Kotaku less as a death sentence and more as an arena to prove his dominance. His strength is undeniable, but it is his unyielding will that makes him truly dangerous—he refuses to bow, even to gods or monsters. Despite his cruelty and arrogance, Chōbei possesses a twisted sense of loyalty, especially toward those he deems his own, revealing that his savagery is rooted not in emptiness, but in a fierce, almost desperate need to assert his existence in a world that has tried to discard him. Spikey blonde hair with braid to his right, in front of his ear. One eye is blind and has a scar over it. The other is red. He was paired with his brother, Toma Aza.

Tamiya Gantetsusai is a living embodiment of raw power and unwavering pride, his massive frame and scarred body bearing testament to a lifetime of battle. A criminal known for his unmatched strength, he faces Kotaku’s horrors head-on, meeting monstrosities with a warrior’s exhilaration rather than fear. Gantetsusai values strength above all else, respecting those who stand firm and dismissing weakness without malice, as though it were simply a natural law. Beneath his rough exterior lies an old-fashioned honor, a belief that one should meet death honestly and without regret. On an island built on deception and false beauty, his straightforward brutality becomes a strangely pure force. Big, muscular, with a spikey mustache and prominent eyebrows, along with sideburns and a beard, all in black. Eyes are dark green(?) and he was paired with Fuchi.

Nurugai is quiet and observant, her small frame and gentle demeanor masking the deep trauma etched into her soul. A native of Kotaku, she is intimately familiar with the island’s cruelty, having survived horrors that shattered her past and stole her innocence. Unlike the others, she does not seek immortality or redemption; she seeks only survival and a fragile sense of belonging. Nurugai’s fear is constant, yet it never fully paralyzes her, instead sharpening her awareness and empathy. In a land where humanity erodes quickly, she stands as a painful reminder of what is lost, her existence proof that Kotaku destroys not only bodies, but futures. She's a little girl, dark skin and curly black hair tied in a ponytail. Due to her appearance, however, she is often mistaken as a boy. Brown eyes, and she was paired with Tenza.

Rokurota is a towering, tragic figure, his immense strength paired with a childlike simplicity that makes his violence both terrifying and heartbreaking. A criminal reduced to little more than a weapon, he lacks malice, acting instead on instinct and loyalty rather than cruelty. On Kotaku, his presence feels almost mythic, as though he were another monster born of the island itself, yet flashes of vulnerability reveal a man stripped of agency and understanding. Rokurota’s tragedy lies in his inability to choose his own path, his overwhelming power serving others while denying him humanity, making him one of Kotaku’s most sorrowful embodiments of strength without freedom. He's huge, labelled as the strongest man on the planet. He dresses like a caveman, and there's a sheet of paper on his face. Black hair in dreads(?) and tan-ish skin. He was paired with Eizen, who he later kills for funsies.

Tensen

Tao Fa is serene, enigmatic, and quietly authoritative, carrying herself with an air of divine composure that makes resistance feel futile rather than frightening. As an immortal being sustained by the immortality elixir, she embodies the Tensen’s belief that life, pleasure, and power are inseparable, viewing tao as a sacred force meant to circulate freely rather than be hoarded. She most often takes a female form, one that is exquisitely beautiful and humanoid, using grace and calm persuasion rather than overt cruelty to assert dominance. Tao Fa regards the intruders on Kotaku with distant curiosity, neither merciful nor openly hostile, seeing them as transient beings bound by mortality. When threatened or when balance must be restored, she sheds her gentle form, revealing a monstrous, flower-born divinity of excess limbs, faces, and petals—a reminder that paradise and horror are the same truth wearing different shapes. Pink eyes and hair, shaped like sakura petals, similar to a bob that went down to her chin. Beautiful and cutesy, playful with light-toned, fair skin.

Zhu Jin is indulgent, playful, and dangerously capricious, treating existence as an endless feast of sensation and curiosity. Though typically appearing female in her refined, alluring humanoid form, her identity is fluid, shifting as tao demands, a natural act rather than a transformation of consequence. As an immortal who drinks the elixir, Zhu Jin believes that desire is proof of life’s supremacy and that cultivating tao through intimacy is not sin, but reverence. She delights in taunting both convicts and Yamada Asaemon, luring them with beauty and false comfort before revealing how insignificant they truly are. In her final form, Zhu Jin becomes a grotesque bloom of flesh and flora, beauty exaggerated into something obscene and overwhelming, reflecting her belief that excess is the purest expression of divinity. Flower petals that are orange with few yellow stripes, petal-like and flying upward. Eyes that fade from orange at the top to yellow at the bottom. Light skin, pretty serious.

Mu Dan is contemplative and aloof, carrying himself with an almost scholarly detachment that sets him apart from the others. He approaches tao not as indulgence, but as a natural law, a cycle to be observed, maintained, and enforced. Though his humanoid form is elegant and calm, usually male, his presence is quietly oppressive, as if the air itself bends around him. As an immortal sustained by the elixir, Mu Man views mortals as incomplete beings—interesting, but ultimately flawed due to their inability to transcend desire and fear simultaneously. When he reveals his true form, his body blossoms into an unnatural garden of eyes, limbs, and faces, each part moving with deliberate purpose, embodying the merciless logic of nature unchecked by morality. Petal-like hair the color of pink peonies, elongated down, center parted and almost like curtain bangs. Golden, glowing eyes, fair, light-toned skin and a lean physique.

Ran is sharp-tongued, prideful, and deeply cruel beneath a polished exterior, taking pleasure in asserting superiority over mortals who dare challenge the gods of Kotaku. Typically presenting as male, Ran shifts forms fluidly when tao must be cultivated, seeing identity as a tool rather than a truth. Immortality has left him contemptuous of struggle, and he views the convicts’ desperation for the elixir as both amusing and pitiful. Ran believes suffering is an inevitable step toward enlightenment, though only the Tensen are worthy of reaping its rewards. His final form is violently distorted, a riot of floral growths and overlapping faces that scream in silent ecstasy, revealing the sadism he keeps carefully hidden behind beauty. Ran has violet hair, in which his left is slicked back, but his right has hair out to make a more elegant appearance. Pink eyes and light-toned skin.

Ju Fa is calm, maternal, and unsettlingly affectionate, treating both allies and enemies with the same gentle tone that makes his violence feel all the more horrifying. Though often appearing male, Ju Fa shifts between forms with ease, embodying the Tensen belief that creation and destruction are inseparable expressions of tao. As an immortal nourished by the elixir, he believes intimacy is a sacred exchange of life force, not bound by shame or restraint. He speaks of paradise as something that must be enforced, even if it means stripping others of their will. In his monstrous form, Ju Fa becomes a blooming nightmare of intertwined bodies and petals, a false womb of divinity that reflects his belief that all things should eventually return to her care. He has long, flowing hair that looks like stripes of shades of yellow and matching yellow eyes.

Rien is solemn, distant, and deeply spiritual, speaking little but observing everything with unnerving clarity. Typically male in form, Rien treats transformation as ritual rather than instinct, shifting only when tao must be balanced or reclaimed. He sees immortality not as indulgence, but as enlightenment earned through perfect harmony with the island’s laws, viewing Kotaku as a sacred body and himself as one of its organs. Mortals seeking the elixir are, to him, contaminants disrupting a holy equilibrium. When Rien abandons his humanoid beauty, his final form is the most alien of all—an overgrown, many-faced deity of flowers and flesh, radiating quiet judgment and absolute finality, embodying the Tensen’s ultimate truth: paradise does not exist for those who cannot endure its cost. Rien too has violet hair, right side slicked back and left side out. Eyes that fade from purple at the top to yellow at the bottom, fair, light-toned skin and an intimidating aura.

Gui Fa is one of the oldest and most enigmatic members of the Tensen, carrying an almost ethereal presence that is matched only by their unsettling silence. Standing between 173 and 185 centimeters depending on the form they assume, Gui Fa possesses short apricot-yellow hair, piercing orange eyes, and distinctive dark sclera that permanently surround their irises, making them visually unique even among the other immortals. Rather than favoring either a masculine or feminine body, Gui Fa almost always exists in an androgynous form, combining both sexes simultaneously instead of shifting between them like the other Tensen. They typically conceal most of their face behind an open book, rarely allowing others to look directly at them, and their expression remains almost perpetually blank. As an immortal sustained by the Elixir of Life, Gui Fa has long accepted the Tensen's philosophy regarding tao and humanity, yet they are markedly quieter than their siblings. Deeply shy and withdrawn, they avoid unnecessary conversation and eye contact whenever possible, preferring observation over participation. Despite their timid disposition, Gui Fa is exceptionally intelligent and specializes in the mystical art of Shu'itsu, approaching conflict with careful calculation rather than overwhelming force. Beneath their reserved exterior lies unwavering devotion to the preservation of Kotaku and the Tensen's existence, believing that humans, with their constant uncertainty and emotional contradictions, can never truly understand the immortal paradise they seek.

Hōko is a gentle tree-being native to Kotaku whose appearance reflects centuries of gradual arborification, the process that transformed him from an ordinary man into something inseparable from the island itself. His body is composed almost entirely of rough, weathered bark, giving him the appearance of a living tree shaped into a human silhouette. His face is simple and worn, with only a single hollow opening serving as his left eye, alongside a carved-looking nose and mouth, while branches and wooden growths naturally form the rest of his body. Though imposing in stature, Hōko's demeanor is anything but intimidating. Soft-spoken, patient, and endlessly compassionate, he offers shelter, food, and guidance even to complete strangers, believing it is his duty to honor the wishes of those who inevitably arrive on Kotaku. Having lost his wife and daughter centuries before to arborification, Hōko eventually discovered the abandoned Mei and raised her as though she were his own child, devoting hundreds of years to protecting and nurturing her. His fatherly love for Mei defines his existence, outweighing even his devotion to the Tensen he once worshipped as gods. Honest to a fault and incapable of deceit, Hōko desires nothing more than peace, yet when Mei's life is threatened, he willingly sacrifices everything he has left without hesitation. His quiet kindness serves as a rare reminder that even on an island ruled by immortals and monsters, genuine humanity can still take root.
