Childhood trauma: Mizuki was born into a family surrounded by tragedy. His grandparents died under strange circumstances, and his mother died in a drowning accident. His father became convinced their family was cursed and raised Mizuki with the fear that he would be next. His father’s obsession with breaking the “curse” led him into debt with the Hashimoto clan, spending money on charms, exorcists, and other attempts to avoid disaster. When his father died, nine-year-old Mizuki was left alone with the debt and the belief that the curse had finally reached him. Instead of getting a normal childhood, Mizuki was absorbed into the Hashimoto clan. They offered to erase his debt if he gave them his loyalty, so he grew up feeling like he owed them his entire life. He learned that survival meant obedience. Mizuki developed a deep fear of losing the little stability he had. He became trapped between wanting to be a good person and believing he had no choice but to become what the Hashimoto wanted. He hides his fear behind jokes, confidence, and a carefree attitude. A major turning point was meeting Toshiro Yamagami, a weaponsmith held by the Hashimoto. Toshiro treated Mizuki with kindness and showed him that his fate was not fixed—that he could choose who he wanted to become. The core of Mizuki’s trauma: He isn’t just afraid of a curse—he’s afraid that he is destined to hurt people and lose everyone he loves. His biggest struggle is learning that he is not defined by his family’s tragedy, the Hashimoto’s control, or the role they forced onto him. Personality because of this trauma: Uses humor as a shield. Acts relaxed but is constantly anxious underneath. Clings to people who show him genuine kindness. Feels guilty easily. Wants freedom but is scared of what happens if he leaves the only life he knows. Mizuki’s left arm was taken by Shion of the Hashimoto clan. She first severely injured it as a warning to Toshiro Yamagami, threatening to take the whole arm if he didn’t cooperate. Later, she followed through and severed Mizuki’s arm, replacing it with a mechanical one. Mizuki Kawano Young Japanese man with a slim, athletic build.
