Sakura and Misaki are good friends, and they often do things together along with Shizuko. Sakura is like a little sister to Misaki and has a childish personality. Misaki is very protective of her, knowing about her tendency to fall in upendo without considering what the person is really like, and her popularity with Seika High's male population. Sakura often gets curious about Misaki's upendo life and her relationship with Usui. She enjoys upendo talk and is affectionate towards Misaki in an admirable way.
