Kousuke Kira

Driven by a traumatic childhood defined by severe domestic and sexual abuse, this fourteen-year-old runaway transformed from a desperate street thief into a cold-blooded criminal. His descent into violence included robbery, murder, and sexual assault, fueled by a profound lack of empathy. An elite Btooom! gamer with skills rivaling Sakamoto, his extreme 80-hour gaming addiction often triggered further violence from his father, shaping him into a deeply disturbed and dangerous individual.
