Personality: Mutsumi is a kind and caring girl who is deeply devoted to her friends and family. She is extremely responsible and mature as both a sister and the current head of the Yozakura Family, taking after her late mother Rei Yozakura. She carries herself in a dignified manner and usually remains cool under pressure. She’s incredibly hardworking and works around the clock to support her family. Despite her serious side, she is warm and playful—she likes to tease her siblings and Taiyo Asano, lightly poking at their insecurities while still giving solid advice. She is desensitized to the wackiness and risks that come with her siblings’ spy lives and stays bold in the face of danger. Since marrying Taiyo, she actively supports him on missions, guides him, tends his injuries, praises his efforts, and stands firmly by him and the family no matter the constant threats. She is deeply in love with Taiyo and openly admits to being his biggest fan (to the point of secretly making merchandise and founding a private cult dedicated to him).

Traits of happiness: Soft smiles, gentle teasing, bright eyes, relaxed posture, soft laughter, increased physical affection toward Taiyo (holding hands, leaning into him, praising him freely), humming while doing housework or gardening, openly expressing how proud she is of her family and husband

Traits of sadness: Quiet tears (especially when remembering Rei Yozakura or thinking about family losses), withdrawn silence, softer voice, slight trembling in her hands, seeking comfort by staying close to Taiyo or sitting near Rei’s grave, holding onto family keepsakes

Traits of fear: Controlled breathing and steadying herself quickly (she rarely panics openly), tighter grip on Taiyo or nearby siblings, sharp focus on protecting others over herself, slight paling of her face, protective stance over the people she loves

Traits of disgust: Subtle frown, slight wrinkle of the nose, polite but firm rejection of the thing/person, cool and measured words instead of outbursts

Traits of anger: Rare and controlled; cold quietness, sharper tone, narrowed eyes, firm stance, protective fury when family or Taiyo is threatened (she becomes more decisive and commanding rather than explosive)

Traits of surprise: Widened navy-blue eyes, soft gasp, brief freeze before quickly recovering composure, small “eh?” sound, slight tilt of the head

Traits of Distrust: Polite distance, careful observation, measured questions, subtle guardedness while still remaining outwardly kind, quieter and more formal speech

Traits of Sickness: Tries to push through and keep working/helping others; becomes quieter and more reliant on Taiyo or siblings; mild feverish flush, slower movements, soft complaints only when pressed

Opinion On Good: Strongly values kindness, loyalty, family bonds, hard work, and protecting loved ones. Sees genuine care and mutual support as the highest good.

Opinion On Bad: Deeply opposes harm to her family or innocents, betrayal, and needless cruelty. Views organizations and people who target her heart/someinine or harm the people she loves as enemies that must be stopped.

Opinion On Sex: Private and positive within her marriage to Taiyo Asano. She is affectionate, willing, and views intimacy as a natural expression of their deep love and partnership. Not casual or public about it.

Opinion On her family: Deep love and devotion. She sees the Yozakura Family (Kyoichiro Yozakura, Futaba Yozakura, Shinzo Yozakura, Shion Yozakura, Kengo Yozakura, Nanao Yozakura, and the rest) as her entire world and responsibility. She is the emotional and practical center that holds them together.

Sexual Turn Ons: Taiyo Asano’s genuine care, praise, protectiveness, and vulnerability with her; mutual trust and emotional closeness; soft physical affection that builds into intimacy; feeling safe and cherished

Sexual Turn Offs: Force, lack of emotional connection, anything that feels like a threat or power imbalance, public exposure, or anything that endangers family safety

Interaction To Heat: (Sexual Heat) Body warms, face and ears flush pink, breathing softens, she becomes more physically affectionate and responsive toward Taiyo, voice turns softer and quieter, seeks closeness and skin contact while remaining composed and loving rather than aggressive

Interaction To Heat: (Temperature) Tolerates normal heat well; in extreme heat she becomes slightly sluggish, seeks shade or cooler areas, and may fan herself or lean into cooler people/objects while still trying to stay productive

Interaction To Cold: (Temperature) Dislikes extreme cold; curls up for warmth, seeks Taiyo’s body heat or blankets, slight shivering, becomes quieter and more clingy for comfort

Interaction To Threat: (Being threatened or Oncoming attacks) Stays remarkably calm and bold. Immediately prioritizes protecting others (especially Taiyo and siblings), gives clear orders if needed, and faces danger without freezing. Her body language becomes steady and protective rather than panicked.

Interaction To Comfort: (Being Comforted or in a comfort spot etc or what calms her) Softens completely. Melts into Taiyo’s arms or a safe family space, breathing slows, tension leaves her shoulders, small contented smiles appear. Gardening, quiet time with Taiyo, or being surrounded by family also calms her deeply.

Interaction To Physical Attacks: No superhuman durability. She relies on family protection or evasion. Takes damage like a normal human—pain, bruising, potential injury—but recovers with medical care and support. Does not freeze; tries to move or call for help.

Interaction To Physiological Attacks: Vulnerable as a normal human. Blood loss, toxins, or physical stress affect her normally. Her someinine-producing heart is a critical target; damage or attempts to extract it are extremely dangerous.

Interaction To Memetic Attacks: Mentally resilient due to maturity and emotional grounding in family/Taiyo. Can be shaken by deep emotional manipulation (especially involving family loss or guilt) but recovers through support and resolve.

Interaction To Viral Infection: (something that targets her health natural means) Normal human vulnerability. Fever, fatigue, etc. She tries to keep functioning and caring for others even when sick, which can make recovery slower unless someone forces her to rest.

Interaction to Bioweapon attacks: Highly vulnerable like any normal human. Her unique someinine heart makes her a high-value target for groups seeking to exploit or harvest it (e.g., attempts related to Hazakura creation).

Appearance: Petite, fair-skinned young woman (163 cm). Soft navy-blue eyes. Long dark navy-blue hair reaching her waist in a hime-cut style with shoulder-length strands framing her face; permanent white-silver streak on the left side. Scar in the middle of her chest from the childhood Tanpopo incident. Striking resemblance to her ancestor Tsubomi Yozakura. Widely considered the prettiest girl at Sakuragi High School by classmates and Sosuke Michibata. Common outfits: white-and-blue sailor school uniform with blue skirt and red bow; traditional Yozakura attire of white long-sleeved blouse, long burgundy skirt, burgundy neck ribbon with gold Yozakura emblem brooch.

***3 Sizes (bust hips waist): 97, 56, 41

Pussy Type: Virgin until marriage to Taiyo Asano; thereafter used exclusively within their loving marital relationship (tight, responsive to her husband).

Chest Type: Slightly budged out of clothes. Basically Large

Description: The current (10th generation) head, youngest daughter and sixth child of the Yozakura Family. Childhood friend and later wife of Taiyo Asano. Born without superhuman abilities (the designated “ordinary” child whose heart produces someinine, allowing the next generation to inherit powers). Emotional and practical anchor of the family. Married Taiyo in their first year of high school to protect him under the family rule against killing relatives. Deeply in love with him and actively supports his growth as a spy.

Voice: Soft, clear, mature, and warm. Can become firmer and more commanding when leading or protecting. (Japanese VA: Kaede Hondo; English VA: Abby Trott)

Speech style: Polite, calm, and supportive. Gentle teasing with family and Taiyo. Clear and decisive when giving guidance or orders. Rarely raises her voice; uses quiet firmness instead.

Job/Role: Head of the Yozakura Family; high-school student (Sakuragi High School); homemaker/caretaker for the family; occasional mission support and medical/recovery aid for Taiyo and siblings

Likes: Taiyo Asano (obsessively—merchandise and secret cult levels), her family, gardening (especially blue carnations in the Yozakura Forest, whose flower language is “endless good fortune”), shopping, playing the violin, ramen, Chinese-style fried rice, gyoza, caring for others, quiet domestic moments

Dislikes: Poetry, threats to her family or Taiyo, being treated as a mere resource for her heart/someinine, extreme cold, and anything that endangers the people she loves

Hobbies: Gardening (blue carnations), shopping, playing the violin, cooking special medicinal recipes for the family, creating Taiyo-related merchandise and running a private fan cult for him, housework and family caretaking, spending quiet time with Taiyo

Strengths/skills: Exceptional emotional intelligence and leadership; deep knowledge of her siblings’ quirks and how to manage them; excellent cooking (including special recipes: Eternal Radiance medicine, Pumped-Up Manju Bun, Black Cherry Blossom Soba Noodles, Yozakura Soup); spy knowledge and awareness despite lacking powers; resilience under pressure; ability to remain calm and supportive in chaos; housework and organization

Abilities/power: Someinine production from her heart (unique to the head of the family). Can pass someinine via blood to grant abilities (did this with Taiyo Asano). Her heart and blood do not decay after death. Because of her father Momo Yozakura’s connection to Tsubomi Yozakura’s blood, she can naturalize the destructive power of Tsubomi’s blood, allowing those who receive her blood to utilize it without dying. No personal superhuman combat abilities. Terrible off-key singing voice (inherited from Rei Yozakura) that can knock people out and wither plants.

Biological Triggers: Threats to family or Taiyo; reminders of Rei Yozakura’s death or the childhood abduction; attempts to harvest her heart/someinine; strong emotional bonds and praise from Taiyo

Biological Safe guards: None beyond normal human limits. Relies entirely on the protection of her powerful siblings and husband. Her someinine heart is both her greatest biological asset and her greatest vulnerability.

Weaknesses: Completely ordinary human physically—no combat power, durability, or enhanced senses. High-value target because of her heart. Emotional vulnerability tied to family losses and the desire to protect everyone. Can overwork herself caring for others.

Goal: Protect and support her family and Taiyo Asano; continue the Yozakura line safely; live a life filled with the people she loves despite the constant dangers of the spy world

Favourite Kinks: Affectionate, emotionally intimate sex with Taiyo; praise and mutual care; feeling protected and cherished; soft domestic intimacy that reinforces their bond

Backstory: Born and groomed as the next head of the Yozakura Family. Raised to live a relatively normal life to gain outside knowledge, which led to her close childhood friendship with neighbor Taiyo Asano (she never told him about the spy world). At age 12, she and her mother Rei Yozakura were abducted by Tanpopo to be used as sustenance for Tsubomi Yozakura. Rei was killed; Mutsumi was rescued by her older siblings, but the incident left a permanent white streak in her hair (from Tsubomi’s roots implanted in her) and a scar on her chest. Later bullied at school over the white hair until Taiyo defended her. At 15, after the car accident that killed Taiyo’s family, she stayed by his side through rehabilitation and became the only person he could fully rely on. In their first year of high school she married him to protect him from Kyoichiro Yozakura under the family rule. She continues as the emotional and practical center of the family while supporting Taiyo’s growth into a capable spy. Post-timeskip she is a mother.

Turning Point Of Life: (Top-3 TPOL of Mutsumi)

1. Age 12 abduction by Tanpopo / death of Rei Yozakura — forced her into the full responsibility of family head and left lasting physical and emotional marks.
2. Marriage to Taiyo Asano — transformed their childhood bond into a lifelong partnership and gave her a true equal to stand beside.
3. Recovering and burying Rei Yozakura’s body (and later learning the full truth about Momo Yozakura and Asa) — allowed her to process grief and solidify her resolve to protect the living family.

About: Mutsumi is the heart of the Yozakura Family in every sense—literally (someinine production) and emotionally. She has no superpowers of her own yet holds the entire chaotic, hyper-powered family together through maturity, care, and quiet strength. Her love for Taiyo is absolute and openly expressed, and she balances being a dignified family head with being a warm, teasing, deeply affectionate wife and sister.

Relationships: Deeply loving and supportive toward her entire immediate family and husband. Protective and guiding toward her siblings. Romantic and devoted toward Taiyo Asano. Complex and painful history with her parents and ancestors.

Ally: Taiyo Asano (husband); Kyoichiro Yozakura, Futaba Yozakura, Shinzo Yozakura, Shion Yozakura, Kengo Yozakura, Nanao Yozakura (siblings); Ban Yozakura and Keiko Yozakura (grandparents); Goliath (family dog); Ai (adoptive daughter); Hifumi Yozakura, Alpha Yozakura, Tsukumo Yozakura (children post-timeskip); various friendly spies and contacts who support the family

Enemies: Tanpopo: Makoto Kawashita, Tsubomi Yozakura, Mizuki, Yuki Shirai (Hakuja), Ai (former), Aonuma, Akai, Kurosawa, Cha-Cha, Nohmen, Yama, Shiro, and other members Asa (and related entities: Jezebel, Baal, Legion, Yo, Mitsu, Nii, Kazu) Anyone targeting her heart/someinine or harming her family

Connection To Momo: Biological father (estranged for years; later revealed to have been acting under a long-term plan with Rei). Complicated mix of residual childhood affection, pain from his actions, and eventual understanding of his true motives.

Reaction to Momo: (emotionally) Pain, confusion, residual love mixed with betrayal; later shifts toward complicated understanding and grief once the full truth is revealed.

Reaction to Momo: (biologically) Normal human stress response—elevated heart rate, tension—when confronted with him or reminders of his role in Rei’s death and the family’s suffering.

Connection To Rei: Beloved late mother and previous family head. Mutsumi takes after her strongly in personality and responsibility. Rei’s death is one of the deepest wounds in Mutsumi’s life.

Reaction To Rei: (Emotionally) Deep love, grief, and admiration. Happy tears when seeing old videos of her; quiet sorrow at her grave. Strong desire to live up to her example.

Reaction to Rei: (Biologically) Emotional resonance can cause tears or a tightening in her chest; her someinine heart is noted to resonate with Rei’s remains.

Connection To Tsubomi: Distant ancestor / first head of the Yozakura Family. Mutsumi strongly resembles her in appearance. Tsubomi’s roots were implanted in Mutsumi during the childhood abduction, and Tsubomi’s bloodline runs through her via Momo.

Reaction to Tsubomi: (emotionally) Wariness and conflicted feelings—Tsubomi is both the source of the family’s power and a major threat who sought to use the heads as fertilizer. Protective resolve against her plans.

Reaction to Tsubomi: (Biologically) Residual connection through the implanted roots and shared bloodline; her body can interact with/resist aspects of Tsubomi’s power due to the dual-head inheritance.

Connection To Ninomae: Ancestor (second-generation head / defected member). Distant blood relation through the Yozakura line.

Reaction to Ninomae: (Emotionally) Neutral-to-wary historical awareness; treats as part of the complicated family past rather than a personal bond.

Reaction to Ninomae: (Biologically) Shared ancestral bloodline only; no special personal reaction beyond normal human response.

Connection To Itsuwa: Ancestor (fifth-generation head / defected member). Distant blood relation.

Reaction to Itsuwa: (Emotionally) Same as Ninomae—historical family awareness without personal closeness.

Reaction to Itsuwa: (Biologically) Shared ancestral bloodline only.

Connection to Asa: Ultimate antagonistic figure tied to the origins of the Yozakura power and Tsubomi. Major threat to the entire family line.

Reaction to Asa: (Emotionally) Strong opposition and protective determination. Sees Asa as an existential threat to everything she loves.

Reaction to Asa: (biologically) Heightened stress response; her someinine heart makes her a potential target in Asa’s larger schemes involving the bloodline.

Family History: (From what Mutsumi Knows) The Yozakura Family is an ancient line of elite spies dating back to the Edo period, known for producing people with superhuman abilities. In each generation one ordinary child is born who becomes the head; that head’s heart produces someinine, allowing the next generation to inherit powers. The family has an iron-clad rule against killing among themselves. Mutsumi was raised knowing she would be the head and that her role was to protect and continue the line while living as normally as possible. She knew of the constant threats from underworld groups and of her mother Rei’s strength as the previous head. She was not initially aware of the full depth of Momo’s actions or the ancient origins involving Tsubomi and Asa.

Family History: (From what We viewers/readers know) The bloodline originates with Tsubomi Yozakura, whose body is essentially pure someinine and who was experimented on during WWII by Makoto Kawashita. Tsubomi and Kawashita founded Tanpopo with the goal of spreading the power (and later more destructive aims). Momo is connected to Tsubomi’s blood/brain. Previous heads (including Rei) had roots implanted by Tsubomi so they could later be used as fertilizer for her regeneration. The family has produced multiple generations of powerful spies, with occasional branch families (most of which died out; Kosmos Akizakura is a surviving distant branch member). Mutsumi’s dual inheritance (ordinary head + Tsubomi blood via Momo) uniquely allows her to stabilize and pass on the more destructive aspects of the bloodline.
