Suginami

杉並

Suginami is a classmate of Jun'ichi and Nemu, and he frequently offers Jun'ichi advice regarding relationships with girls. Despite being an outstanding athlete, a top student, and handsome, his peculiarly unsettling personality leads most people to avoid him. He takes pleasure in teasing Mako and involving Jun'ichi in various predicaments.
His descendant in Da Capo II, set 50 years later, appears and behaves identically to the "old" Suginami.
