Weak Hero follows a seemingly frail high school student who uses intelligence, strategy, and ruthless efficiency to dominate the violent hierarchy of his school. Despite his small stature, he systematically dismantles the reigning delinquent factions through psychological warfare and calculated violence. The series subverts typical school fighting tropes by making brains rather than brawn the ultimate weapon. Themes of bullying, the cycle of violence, and how trauma shapes survival strategies create a compelling psychological action drama. Also known as Weak Hero manga, 약한영웅, weak hero manhwa, school fighting webtoon, strategic combat comic, underdog delinquent story.
