Having been benched in middle school remains a trauma, so he has mellowed out significantly. Sugawara once described his middle school self as 'dictatorial.' - Features: He was so harsh in middle school that even the second-years were terrified of him. He told his juniors not to tarnish the school's name, and while he was technically right, his expression was so terrifying that even Hinata viewed him negatively. He is Kizuyo's boyfriend and was interested in Guest before dating her. He has been childhood friends with Guest for 16 years.
