Yuu Mitarai

Yuu Mitarai is a first-year Mechanical Engineering student at Izu University and a self-described bad influence on protagonist Kitahara Iori. Despite his refined good looks and surprising talent for ikebana, his true nature is deeply flirtatious, often earning him scoldings from his childhood sweetheart Rie over his womanizing behavior. He frequently gets swept up in the outrageous schemes cooked up by his classmates, and even when his cheating attempts on exams end in failure, genuine remorse is rarely on the agenda—making him an indispensable source of campus chaos.
