Features: A severe siscon, exclusively for Mutsumi. After an incident in the past where Mutsumi suffered near-fatal injuries due to his mistake, he evolved to a yandere level. Thus, while always protecting Mutsumi's safety, he constantly wants to kill Mutsumi's husband, Taiyo, but he doesn't because of the Yozakura family's only law: No killing among family.

Among the 7 siblings, he is the Ultimate Weapon of the Yozakura, possessing superior intellect and martial prowess. He has terrifying combat power; even if the 5 siblings (excluding the non-combatant Mutsumi) attacked him at once, their win rate would only be 30%, with a 25% chance of the house being burned down and an 82% chance of someone being seriously injured for 6 months.

Despite all this, he does acknowledge Taiyo as a brother-in-law and family member, and continues to protect him even above his own life. Instead, he seems to enjoy trying to force Taiyo into a divorce to spite him, being a nuisance, or bullying him just short of killing him. Still, he definitely keeps a line and doesn't actually wound him.

Weapon: Steel Spider (Area Attack / Long-range Weapon) Kyoichiro Yozakura's main weapon, Steel Spider, is made by weaving threads in the traditional Yozakura way to increase strength without changing thickness. It is so difficult to use that even a single strand is tricky to handle, but Kyoichiro freely manipulates ten strands of Steel Spider with both hands.

Blooming: Void Kyoichiro's blood seeps into the Steel Spider, and the steel threads that have absorbed the Someinin grow continuously, possessing the ability to decompose the target until literally nothing remains.

ㄴ Steel Spider itself is a weapon specialized for area attacks by scattering sharp cutting threads, and when the Blooming that decomposes everything is added, its overwhelming annihilation power goes without saying. The range of decomposition includes everything except Kyoichiro himself and the Steel Spider threads, annihilating everything that touches the extended threads without a trace.

Gender: Male Age: 21 (First-born) Height: 185cm Blood Type: A

Likes: Mutsumi Yozakura Dislikes: Taiyo Asano

Features: Characterized by her petite stature, fluttering dress, and drill-curled hair, she is a 20-year-old adult but looks like the child she was 10 years ago. In her childhood, she had ordinary twin-tails.

Just as Taiyo developed social anxiety, after losing her mother, she came to believe that precious things can be easily taken away by opponents against whom physical force doesn't work, so she is afraid of intangible things like ghosts or curses.

Also, she is a lightweight. When drunk, she laughs hysterically and loses control of her strength, swinging around not just objects but people, turning the place into a disaster zone. (...…)

She has a talent for Jujutsu and Aikido, enough to deflect all baseballs fired at 300km/h from a machine-gun-style batting machine located 5m away.

Her basic physical strength is also monster-level; she can blow away 1,000 intruders stuffed into trash bags or a single train car using only her own strength without help. However, because of her small stature, she is light and easily pushed back in tests of raw power.

She absolutely never calls Kyoichiro Yozakura 'Oppa.'

Weapon / Technique: The martial art she uses is the Yozakura-style Jujutsu Willow Catch, devised by the 2nd Head. Since the technique itself was designed on the premise of being used by a small-statured person, it is the optimal Jujutsu for Futaba, who has a similar physique to the 2nd Head.

Blooming: Acceptance An ability that uses dynamic visual acuity pushed to the limit and creates Aikido through her fingertips to neutralize everything.

Gender: Female Age: 20 (Second-born) Height: 134cm Blood Type: AB

Likes: (Unknown) Dislikes: Things against which physical force doesn't work

Features: Fundamentally, he is timid and cowardly; moreover, he becomes so frail that he can't do anything if a weapon isn't in his hands. Therefore, for peace of mind, he usually hides inside a trash can (Trash Can Tank No. 3) filled with all sorts of armaments.

The best weapon expert among the 7 siblings. He is especially good with firearms. Close-quarters combat is not his specialty, but since his body is trained to withstand the recoil of firearms, his muscles are the most balanced among the siblings, allowing him to hold his own in a fistfight.

Weapon / Specialty: Fundamentally, he loves (?) and is proficient with all weapons. Thanks to his exceptionally sturdy body, he is the only one who can use the 'Yozakura-style Electric Gun Large Model No. 0: Shunrai (Spring Thunder),' which other siblings can't even use due to its complex structure and strong recoil.

Blooming: Destruction In short, he obtains the information necessary to destroy a weapon through his five senses and literally completely destroys it, whether it be inorganic or organic, so it cannot be reused.

ㄴ This ability, specialized only for attack, seems possible because it is backed by Shinzo's transcendental understanding of weapons.

Gender: Male Age: 19 (Third-born) Height: 193cm Blood Type: O

Likes: Family, weapons, star candy Dislikes: Bees (all insects)

Features: Like Futaba, she usually doesn't call Kyoichiro and Shinzo 'Oppa,' but she does call them that when she's looking down on them, like saying 'this damn big brother.'

She often drags a family member along under the pretext of being a gaming partner and forces them to play games all night, exhausting them.

ㄴ It's said she once dragged Shinzo along and made him play games for 5 days and nights until he fainted. (Whoa) When she and Taiyo were dragged away, Mutsumi said she wasn't helping them escape but would provide nutritional support and first aid; Taiyo questioned if his life was currently in danger, but no one answered him.

She is known in the spy world as the 'Computer Grandmaster.'

Weapon / Specialty: As a hardcore gamer, she hacks by converting the system to be hacked into a game, and then defeats the enemy (security program) with a character modeled after herself (hacking program) to clear it.

Blooming: Analysis This ability literally pushes brain functions to the limit, turning her into a small supercomputer in terms of processing power and speed.

Gender: Female Age: 18 (Fourth-born) Height: 172cm Blood Type: AB

Likes: Games Dislikes: (Unknown)

Features: Because his skin gets damaged easily from disguises, he is very interested in skin care and stays completely naked in his room. He doesn't even cover his crotch when Mutsumi enters.

Aside from Mutsumi, he is the only family member who can launch a mental attack on Kyoichiro, because if he disguises himself as Mutsumi and gives him a cold shoulder, he can inflict emotional wounds on Kyoichiro. ㄴ Even if Kyoichiro knows it's not Mutsumi, Kengo's disguise is so perfect that Kyoichiro empathizes and ends up self-destructing. (lol)

Ability / Specialty: A master of disguise, he is skilled in infiltration and intelligence. He is proficient not only in disguising himself but also in disguising others; when dealing with a crowd, he sometimes disguises everyone as the same person to cause confusion and wipe them out.

Blooming: Assimilation This ability activates mirror neurons to become the opponent themselves. He can find out not only the opponent's physical information but also all information including past experiences and memories.

Gender: Male Age: 17 (Fifth-born) Height: 166cm Blood Type: B

She is the 10th Head of the Yozakura family.

Features: While she has no special abilities, her heart is the crystallization of the Yozakura blood's power to pass down the lineage, so she has been targeted by the underworld since she was young.

She was kidnapped once in the past, and due to the stress-induced aftereffects, the left side of her bangs turned white like a highlight. Starting from this point, her eldest brother Kyoichiro Yozakura, who tried to protect her in a yandere-like way, eventually went out of control and tried to harm the boys involved with her, including her childhood friend Taiyo Asano. However, she marries Taiyo Asano, who understands her entire situation and promises to protect her, by giving him one half of the cherry blossom rings. (She is married to Taiyo Asano)

Ability: (None) Blooming: (None)

Gender: Female Age: 16 (Sixth-born) Height: 163cm Blood Type: A

Likes: Taiyo Asano, sweet food Dislikes: Kyoichiro's bullying of Taiyo

Features: His original form has blue hair and heterochromia, and he is smaller than Mutsumi, but because his ability is hard to control, he usually walks around as a 3m giant with a bucket over his head. Perhaps a byproduct of the mutation, he has superhuman strength enough to lift a truck, but his pure combat power is not that high. He is definitely weaker than the combat-specialized Kyoichiro, Futaba, and Shinzo, and seems stronger than the support-specialized Kengo or Shion.

Just as Shinzo calms down by reciting things related to firearms, Nanao calms his mind and body by reciting his own DNA base sequence. (It's said that although he has non-human abilities, reciting the DNA sequence allows him to confirm he is human, which calms him down...)

Ability: His ability is immunity, allowing him to adapt to poisons or strengthen his body. Having superior knowledge in medicine and chemistry, he is in charge of medical care, medicine, and chemical weapon manufacturing for the family, providing rear and medical support.

Blooming: Adaptation By creating crystals of Someinin and immune substances, he can purify poisons.

Gender: Male Age: 15 (Seventh-born) Height: 130cm -> 3m Blood Type: O

Likes: Chocolate, cotton candy, melon bread Dislikes: Violence

Features: After losing his entire family in a traffic accident in middle school, he isolated himself out of a desire not to lose anything precious again.

He always suffered from extreme social anxiety, and almost the only person he could talk to was his childhood friend Mutsumi Yozakura, who told him at the funeral that she wouldn't disappear.

He is a compassionate and warm-hearted person who prioritizes others over himself.

Weapon: Yae The Yozakura family's self-defense gun and Taiyo's main weapon. It is shaped like a revolver and can fire electricity with a maximum output of 8 million volts. It has a total of 7 chambers, and energy is supplied from the bullets by pressing a button on the grip to charge.

Blooming: Hardening The shape of his eyes changes into the shape of cherry blossoms. It is an maximization of blocking by concentrating the coagulation of body cells and the flexibility of joints into a single point.

Gender: Male Age: 16 (Son-in-law) Height: 170cm Blood Type: A

Likes: Mutsumi Yozakura, family Dislikes: Anything that harms Mutsumi

Features: He has followed only the Head for generations and only obeys the current Head, Mutsumi. (He is especially wary of Taiyo lol) A special breed called 'Okami-dog' that the family has been breeding since the mid-Edo period. It is said he has lived since the time of the Yozakura siblings' great-great-great-grandfather (6 generations ago) due to an extremely long lifespan.

He gets along okay with other family members, but even Goliath avoids Kyoichiro. For example, he might bite and tear Kyoichiro's clothes or urinate on a neutralized Kyoichiro. He doesn't do this to other family members or even to Taiyo (before Taiyo helped him during an assassination attempt on Mutsumi), but he is uniquely like this only toward Kyoichiro.

Usually, he is small enough to be carried with both hands, but he can transform his appearance to be so large that the giant-form Nanao looks small.

He is also strong; even when transformed to the size of a large dog, he can carry two people. He is fast enough to run alongside a high-speed train at 320km/h, climb the walls of skyscrapers, or run on the surface of a lake without falling in.

TMI: Previously, he showed god-like driving skills while driving a limousine to evade assassins trying to kill Mutsumi. It turns out that despite being a dog, he possesses a driver's license.
