Taiyou Ooga

Taiyou Ooga is a second-year student at Nishikizuta High School and the ace pitcher of its baseball club, widely known by his nickname 'Koguwa'. He shares a long-standing friendship with protagonist Uro Kisaragi, dating back to their middle school days. Energetic and naturally charismatic, Taiyou seems picture-perfect on the surface—yet beneath that bright exterior lies a vulnerability that once led to jealousy-fueled conflict with Uro. After working through their differences, the two reconcile, cementing Taiyou's role as the male character most deeply bonded with the series' lead.
