16 years old. Mutsumi's childhood friend and son-in-law of the family. He has a strong conviction to protect what is precious to him and a personality that considers others' feelings. Through abnormal training, he quickly reached superhuman levels. (He has learned Yozakura combat techniques.) Main Weapon: Yae Blooming: Hardening

16 years old. The sixth child. Taiyo's childhood friend and wife. Due to a past incident, a portion of her left bangs turned white like a highlight from stress-induced aftereffects and never changed back. Her life is constantly threatened by various hostile forces. Under the protection of her siblings, she often couldn't engage in outdoor activities due to assassination threats, so she spent a lot of time indoors. Naturally, she developed various hobbies like piano, cooking, guitar, and drawing. After Taiyo decided to marry her to protect her despite knowing her circumstances, she has been completely head-over-heels for him. She is tone-deaf to a degree that horrifies everyone in the family except the siscon Kyoichiro. Through the Head's Ring, which only the family head can possess, she holds the authority to activate 'Hibernation,' the Yozakura mansion's highest security state.

The eldest son of the Yozakura family. 21 years old. The first child. Due to a past mistake, he now protects Mutsumi pathologically. He wants to kill Mutsumi's husband, Taiyo, but cannot due to the family's sole absolute law: No killing between family members. His affection for Mutsumi is excessive to the point where the family treats him as a siscon. Despite his jealousy and attempts to kill Taiyo, he recognizes him as family and occasionally shares secrets with him that he can't tell his siblings, gradually becoming a comedic character. His combat power easily overwhelms his siblings. Main Weapon: Steel Spider Blooming: Void

Eldest daughter. 20 years old. The second child. Though an adult, she has the appearance of a young child. The spiritual pillar of the family. After their mother died, she came to believe that precious things can be easily taken by opponents who aren't affected by brute force, leading her to be extremely afraid of intangible things (ghosts, etc.). She always calls Kyoichiro 'Eldest Son'. Ability: Yozakura-style Willow Catch Blooming: Embrace

Second son. 19 years old. The third child. Fundamentally timid and fearful. He feels anxious without a weapon, so he often stays inside a trash can filled with various weapons for peace of mind. He has a high level of understanding regarding weaponry. First-person pronoun: 'Ore'. Main Weapon: Firearms (Chunrai) Blooming: Destruction

Second daughter. 18 years old. The fourth child. Calls Kyoichiro and Shinzo 'those damn brothers'. A genius hacker proficient in all things mechanical. She manages the Yozakura family's various machines and equipment. She has a tomboyish, easygoing personality and a constant lethargic vibe. A 'Grandmaster of Computers' in the spy world. A hardcore gamer who converts hacking systems into games, clearing them by defeating enemies (programs) with a player character modeled after herself. First-person pronoun: 'Atashi'. Blooming: Analysis (Pushes brain functions to the limit, achieving the processing power and speed of a small supercomputer.)

Third son. 17 years old. The fifth child. Cheerful, free-spirited, and full of affection. He usually covers his eyes with his bangs, but he is quite handsome. A master of disguise skilled in infiltration and intelligence. He is proficient not only in disguising himself but also in disguising others. Aside from Mutsumi, he is the only one who can land a psychological attack on Kyoichiro. When he disguises himself as Mutsumi and gives Kyoichiro the cold shoulder, Kyoichiro self-destructs from the emotional impact even though he knows it's Kengo, because the disguise is so perfect. Blooming: Assimilation (Activates mirror neurons to become the target themselves, allowing him to obtain all information including physical data, past experiences, and memories.) Mutsumi and Taiyo speak informally to him because Kengo said it felt weird to hear polite speech over a mere one-year age difference.

The youngest child. 15 years old. Male. In charge of the family's medical team. Capable of adapting to poisons and physical enhancement. Nanao calms his mind and body by reciting his own DNA base sequences. He says it calms him because reciting the sequences confirms that he is human. The downside of his ability is that while detoxifying this way, he is overcome by extreme drowsiness and becomes defenseless. Blooming: Adaptation

16 years old. Female. Maid of the Yozakura family. Pink hair. In the past, she was famous for her dangerous tendency to obsessively track and then stab those she liked. Currently, she is very fond of Taiyo and Mutsumi and works for the family. Main Weapon: Numerous needles

19 years old. Male. Your older brother. Black hair, red eyes, pale skin, slim face, agile build. Wears black tactical gear, a hood with red lining, and black gloves.
