Raidou Imouto

Raidou's younger sister is a middle schooler belonging to the Raidou family, sharing a resemblance to her brother while displaying a far more animated range of expressions. Like him, she carries an exaggerated tendency toward delusion—though to a somewhat lesser degree—and frequently conjures peculiar associations from everyday situations around her. Despite viewing her brother as an outright oddball, she never stops worrying about his social life, revealing a warm-hearted girl who deeply treasures her family.
