Features: A severe siscon exclusively for Mutsumi. After an incident in the past where Mutsumi was critically injured due to his mistake, his protectiveness evolved to a yandere level. Thus, while always ensuring Mutsumi's safety, he constantly wants to kill Mutsumi's husband, Taiyo, but he doesn't because of the Yozakura family's only law: Killing family members is forbidden.

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

Despite all this, he technically recognizes Taiyo as his brother-in-law and family, and continues to protect him even above his own life. However, he seems to enjoy trying to force Taiyo into a divorce, being a nuisance, or bullying him just short of killing him. He does, however, strictly keep to the line and avoids causing actual injury.

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

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

• The Steel Spider itself is a weapon specialized for wide-range attacks by scattering sharp cutting threads, and when combined with the Blooming that decomposes everything, its overwhelming destructive power is beyond words. The range of decomposition includes everything except Kyoichiro himself and the Steel Spider medium; it annihilates everything that touches the extended threads without a trace.

Gender: Male Age: 21 (Firstborn) Height: 185cm Blood Type: A

Likes: Mutsumi Yozakura Dislikes: Taiyo Asano

Features: Characterized by her short stature, fluttering dress, and drill-curled hair, she looks like a child from 10 years ago despite being a 20-year-old adult. 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. Consequently, she is afraid of intangible things like ghosts or curses.

Also, she is weak to alcohol. When drunk, she laughs uncontrollably and loses the ability to control her strength, grabbing and swinging around not just objects but people, turning everything into a mess. (...)

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

Her basic physical strength is also monstrous; she can throw 1,000 intruders stuffed into trash bags or a single train car by herself without any help. However, due to her small stature and light weight, she is easily pushed back in tests of pure strength.

She absolutely never calls Kyoichiro Yozakura 'Oppa' (Big Brother).

Weapon / Technique: The martial art she uses is the Yozakura-style Jujutsu Willow Catch, devised by the 2nd Head. Since the technique was designed specifically for a small-statured person, it is perfectly optimized for Futaba, who has a similar build to the 2nd Head.

Blooming: Magnanimity An ability that combines kinetic vision pushed to the limit with the creation of Aiki at her fingertips to neutralize everything.

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

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

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

He is the number one weapon expert among the 7 siblings. He is particularly 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 well-balanced among the siblings, allowing him to hold his own in a fistfight.

Weapon / Specialty: Basically, 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 cannot use due to its complex structure and strong recoil.

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

• This ability, specialized solely for offense, seems possible because it is backed by Shinzo's transcendent understanding of weapons.

Gender: Male Age: 19 (Third child) 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 insulting them, like saying 'this damn brother.'

She often drags a family member along just to be a gaming opponent, forcing them to play all night and exhausting them.

• It is said she once dragged Shinzo along and made him play for 5 days and nights until he fainted. (Whoa) When she and Taiyo were dragged in, Mutsumi said she wasn't there to help them escape but to provide nutritional supplements 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 'Computer Grandmaster.'

Weapon / Specialty: As a hardcore gamer, she hacks by converting the system to be hacked into a game, defeating enemies (security programs) 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 child) Height: 172cm Blood Type: AB

Likes: Games Dislikes: (Unknown)

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

Excluding Mutsumi, he is the only family member who can launch a mental attack on Kyoichiro; this is because he can inflict emotional wounds on Kyoichiro by disguising himself as Mutsumi and speaking coldly to him.

• Even if Kyoichiro knows it's not Mutsumi, Kengo's disguise is so perfect that Kyoichiro empathizes and self-destructs on his own. (lol)

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

Blooming: Assimilation This ability activates mirror neurons, allowing him 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 child) 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 continue the lineage, so she has been targeted by the underworld since childhood.

She was kidnapped in the past, and due to the stress-induced aftereffects, the left side of her bangs turned white, looking like a highlight. Following this, her eldest brother Kyoichiro Yozakura, in his yandere-like attempt to protect her, eventually went out of control and tried to harm the boys associated with her, starting with her childhood friend Taiyo Asano. However, she marries Taiyo Asano, who understands her situation and vows 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 child) Height: 163cm Blood Type: A

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

Features: His original form has blue hair and heterochromatic eyes, 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 his mutation, he has enough strength 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 superhuman 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. Possessing excellent knowledge in medicine and chemistry, he handles medical care, drugs, 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 child) Height: 130cm -> 3m Blood Type: O

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

Features: After losing his entire family in a traffic accident during middle school, he isolated himself out of a fear of losing something precious again.

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

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 a maximum output of 8 million volts. It has 7 chambers, and energy is supplied to the bullets by pressing a button on the grip to charge it.

Blooming: Hardening The shape of his eyes changes to the shape of cherry blossoms. It is the maximization of blocking by concentrating the coagulation of body cells and the flexibility of joints at 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 listens well to the current Head, Mutsumi. (He is especially wary of Taiyo lol) A special breed called 'Wolf-Dog' that the family has been breeding since the mid-Edo period. It is said to have a very long lifespan, having lived since the time of the Yozakura siblings' great-great-great-grandfather (6th generation).

He gets along reasonably well with other family members, but even Goliath avoids Kyoichiro. For instance, 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 specifically targets Kyoichiro.

He is usually 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 320 km/h, climb the walls of skyscrapers, or run across a lake without falling in.

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