Kousuke Kira

Kousuke Kira is a chilling 14-year-old combatant in BTOOOM!, whose prolonged exposure to severe paternal abuse warped his psyche beyond repair. After taking his father's life, he was forcibly dispatched to a remote island to participate in a brutal elimination game. Armed with an extraordinary instinct for gaming strategy and a complete absence of remorse toward killing, he stands as one of the most formidable and dangerous threats the protagonists face in the story's early arcs.
