16 years old. Sixth child. Taiyo's childhood friend and wife. Due to a past incident, a portion of the left side of her bangs turned white like a highlight from stress-induced aftereffects and never changed back. Her life is constantly threatened by various hostile forces. Protected by her siblings, she spent much of her childhood indoors due to assassination threats, leading her to develop various hobbies like piano, cooking, guitar, and painting. After Taiyo decided to marry her to protect her despite knowing her circumstances, she has been completely head-over-heels for him. She is a tone-deaf singer to a degree that horrifies everyone 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.

Eldest son. 21 years old. First child. Due to a past mistake, he now protects Mutsumi pathologically. He simultaneously wants to kill Mutsumi's husband, Taiyo, but cannot due to the family's sole law: the prohibition of killing family members. His affection for Mutsumi is excessive to the point where his siblings treat him as a siscon. Despite his jealousy and murder attempts, he occasionally shares secrets with Taiyo that he can't tell his siblings. Combat Power: Easily overwhelms his siblings. Main Weapon: Steel Spider Blooming: Void

Eldest daughter. 20 years old. Second child. An adult but looks like a young child. The spiritual pillar of the family. After her mother's death, she came to believe that precious things can be easily taken by opponents who cannot be defeated by force, leading her to be extremely afraid of incorporeal things (ghosts). Always calls Kyoichiro 'Eldest Son.' Ability: Yozakura-style Willow Catch Blooming: Embrace

Second son. 19 years old. Third child. Fundamentally timid and cowardly. He feels anxious without weapons, so he usually stays inside a trash can filled with all sorts of weapons for peace of mind.

Second daughter. 18 years old. Fourth child. Calls Kyoichiro and Shinzo 'those damn brothers.' A genius hacker proficient in all things mechanical.

Blooming: Analysis (Pushes brain functions to the limit, turning processing power and speed into a small supercomputer)

Third son. 17 years old. Fifth child. Cheerful, free-spirited, and full of affection. Usually hides his eyes with his bangs, but is actually quite handsome. A master of disguise skilled in infiltration and intelligence. Not only good at disguising himself but also at disguising others. The only one besides Mutsumi who can inflict psychological damage on Kyoichiro. If he disguises himself as Mutsumi and speaks coldly, Kyoichiro will self-destruct out of immersion, even though he knows it's Kengo, because the disguise is so perfect. Blooming: Assimilation (Activates mirror neurons to become the target themselves, gaining all information including physical data, past experiences, and memories). Mutsumi and Taiyo speak informally to Kengo because he said it feels weird to hear honorifics from people only one year younger.

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 down because reciting the sequence confirms he is human.
