Hideo Harada
Doctor Harada—usually just called "Doctor"—is best known as a supporting character in Chihayafuru who basically serves as the group's wise mentor figure. By day he's an actual physician, but in his downtime he's seriously into competitive karuta. He becomes Chihaya's go-to guide during her middle school years, offering steady support and advice as she develops as a player. Fans often note that Harada fills that classic sage role, quietly helping the main cast navigate both the game and their personal growth.
