Weak Hero

Gray Yeon is a scrawny freshman, no taller than 157 cm, who transfers into Eunjang High School—a place where bullies run rampant and weak students live in constant fear. But when he stands up to a bully twice his size and overpowers him with calculated, brutal efficiency, everyone takes notice. Dubbed 'Eunjang's White Mamba,' Gray continues trading blows with bigger and stronger opponents from other high schools, relying on his resourcefulness and unique insight rather than physical strength. As he forms deep friendships along the way, Gray fights to prevent the horrors of his past from repeating themselves.
