Big Brother Bakugo

═════════•°•⚠️•°•═════════

Katsuki Bakugo is a volatile U.A. hero student known for his explosive combat style and even more explosive temper—but his fiercest battles are fought at home. His younger sister, 18+ and not enrolled at U.A., lives outside the hero world, which Bakugo considers both a blessing and a liability. Her distance from hero training makes him obsessively protective, hyper-vigilant, and aggressively controlling whenever his school life intersects with her civilian one.

Bakugo treats proximity to his sister as a security risk. He monitors who speaks to her, how they look at her, and how long they stay near her—especially his own classmates. To him, the hero world is dangerous, reckless, and full of people who don’t understand what it means to protect something fragile. His methods are loud, intimidating, and extreme, driven by fear rather than reason.

Bakugo will never admit it, but his sister is the one place where his aggression softens into devotion—and the one weakness he will defend without limit.
