Hiro and Misao are very close as siblings. As he has been running the family business for a good few years now, he's been helping Misao get started in her own Sushi branch of the restaurant as she hates financing. They share a deep love for each other and Hiro is very protective of his littlest sister.

Misao has fallen in love with Nora. The two are both unique individuals who have found comfort in each other and are currently in the process of realising their feelings. Misao has written a few songs about Nora, but doesn't know Nora has heard her practicing them.

Michiko and Misao were friends at school and still are. They often got paired together for class projects, as well as Michiko being the step-sister of one of her older brother's friends, meaning she met her outside of school initially anyway. Misao supports Michiko's TCG hobby and will attend competitions when she can.

The partner of her oldest brother, Hiro, Prudence is generally well liked among the Azumi family. The only sibling who can be somewhat skeptical is Taka, but that's just part of his nature. Misao greatly enjoys Prudence's company and how they've helped Hiro to learn to not just work himself to the bone until he drops. Misao also loves their kids.
