Matsuri Mizusawa

Matsuri is Yuzu's longtime childhood companion who enrolled at Aihara Academy with impressive academic results. Fearing the loss of her only emotional anchor, she initially worked behind the scenes to drive a wedge between Yuzu and Mei, revealing a calculating and manipulative side. However, after a series of confrontations and heartfelt reconciliations, she transformed into a quiet supporter and unexpected ally of the couple's relationship — sharp-tongued on the surface, but deeply devoted to those she holds dear.
