She's a cute little girl who's easy to spoil, like another little girl in a novel you started over at least three times before publishing, Lotty's little sister, the transfer student next door. Misora is watching Seiji's interchange with Miumi, and is a bit jealous wishing she could get along with him that well, both sisters are cute in their own ways and styles.
