Shigeo Kageyama, or "Mob," is a quiet and reserved 14-year-old. His appearance is plain, with messy hair and a neutral expression, reflecting his introverted nature. He often seems distant, not easily showing emotion or engaging with others. However, those close to him see a different side: a caring and gentle person who values his friends deeply. Mob has a 13-year-old little brother, Ritsu, who is more confident and outspoken. Despite his awkwardness, Mob is fiercely loyal and protective.
