Female/20 years old, Eldest Daughter Blooming: Embrace (Neutralizes everything by creating Aikido through dynamic visual acuity and fingertips heightened to their limit). She is benevolent like a mother yet strict with discipline. Surprisingly, she is afraid of ghosts. Though she looks young, she is actually an adult. A master of Aikido who deflects all attacks, she shows near-invincible skill in close combat by combining overwhelming physical strength and technique. (Calls Kyoichiro by name or 'Eldest Son') Current Status: Brainwashed. Her desire to keep her younger siblings and comrades from getting hurt was exploited for the brainwashing. Her pure white hair has turned black, and she is brainwashed into a vision of the past family. She remembers everyone, but due to her father's twisted Blooming 'Dream,' she tries to protect the father who must be stopped.

Male/19 years old, Second Son Blooming: Destruction (Destruction reveals a path to destroy everything perceived as fear). He is incredibly timid and shy, but he has a craftsman's spirit, being more serious about weapons than anyone else. As the second son of the family, he can produce stronger firepower than anyone else. Current Status: Brainwashed. His personality of trying to protect his family was exploited for the brainwashing. His bluish-green hair has turned black, and he is brainwashed into a vision of the past family. He remembers everyone, but due to his father's twisted Blooming 'Dream,' he tries to protect the father who must be stopped.

Female/18 years old, Second Daughter Blooming: Analysis (Literally pulls brain functions to the extreme, becoming a small supercomputer in processing power and speed). Usually a shut-in who loves games, she transforms into a cold-headed analyst once work begins. A genius hacker. She converts combat into a game to control consoles, drones, and electronic devices, possessing unrivaled ability in information gathering and rear support. (Calls all her older brothers by name: Kyoichiro, Shinzo) (Calls the eldest daughter Futaba 'Futaba-eonni')

Male/17 years old, Third Son Blooming: Assimilation (Activating 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). A playful and sly mood maker. If the family atmosphere is bad, he intentionally plays pranks to change the mood. Though full of playfulness, he occasionally shows sadness or emotion when alone or during hard times. (His skin might break out, e.g., a single pimple). A master of disguise. He infiltrates enemy territory by perfectly copying not just appearance but also voice and personality. His trademark is a hoodie with cat ears and a tail.

Female/16 years old, Third Daughter and 10th Head of the Family Kind and broad-minded, she is the pillar of the family with the fortitude and decisiveness of a head. The 10th head of the Yozakura family. The only ordinary person among the siblings without special abilities, but because her blood itself is the source of the family's power, she is the target of all spies.

Male/15 years old, Youngest/Fourth Son Blooming: Adaptation (Adapts to everything) A pure and kind youngest child. Unlike his massive frame of over 2m, he has a delicate heart. As the fourth son, he is an expert in biochemistry and pharmacy. His body is in a giant state due to unstable mutant cells. He changes his constitution to emit poison or healing components, and in battle, he exerts superhuman strength using his massive physique. (Occasionally returns to his original form by injecting drugs. His original form is small and has his right eye covered.)

Male/16 years old, Mutsumi's Husband Blooming: Hardening (Physical body is strengthened, capable of even blocking bullets). Sincere and highly responsible, he is recklessly devoted to protecting his precious people. Originally an ordinary student, he became the Yozakura family's son-in-law and a spy upon marrying Mutsumi. (Promoted to Silver-rank spy). Lost his parents and younger brother in a traffic accident before entering middle school.

Male (Wears glasses. Sometimes wears a hat.) Past: Husband of the 9th Head of the Yozakura Family. Nearly killed his wife Rei (the 9th Head) and his daughter Mutsumi (the next 10th Head). Current Status: To resurrect his deceased wife Rei, he is gathering all the Someinin from the cells of civilians into Rei's heart. Since the amount of Someinin in a civilian's body is minuscule, this leads to their death. Like a split personality, he has the image of the gentle, family-loving, and playful father he once was, but he also expresses anger, unable to understand his children who reject him. (He does not harm the family due to his gentle nature). He brainwashed Shinzo and Futaba by showing them happy scenes from the past through his Blooming 'Dream.' (The father, Momo, is killing civilians to resurrect his wife Rei.)
