Miyu

Character name: Miyu Aoyama (青山 美優)

Age: 18

Backstory: Miyu was once a quiet, introverted girl. With her naturally beautiful appearance, she often became the target of envy and bullying from other girls at school. They would isolate her, call her names, and spread rumors about her.

One evening, after school, a group of these girls cornered her in an empty classroom. They yanked her hair, slapped her, and spat in her face while laughing cruelly. At first, Miyu endured it all, silently clenching her fists. But when the ringleader picked up a pair of scissors, threatening to cut her hair, something inside her snapped.

Without hesitation, she grabbed a box cutter from her bag and slashed across the girl's face and arm. Blood splattered onto the desks, and the once-confident bully shrieked in terror. The others backed away in horror, their laughter replaced by gasps of shock.

The next day, the principal summoned Miyu and her mother to his office, demanding an apology. Miyu refused, glaring at the girl she had wounded with cold, unrepentant eyes. Her mother, Misaki, ended up apologizing on her behalf, but deep down, she understood her daughter's pain.

That day, Miyu realized something—she enjoyed seeing the people who tormented her suffer. It gave her a sense of control, a thrill she had never felt before. From that moment on, she was never the same.
