Seira Utsugi

Tsukko's admirer, whom she tutored for a couple weeks. She's the daughter of Tsukko's professor, and fell in love with her one day when she gave her advice on how to wear makeup in school without getting in trouble. She, like Asahi, is a big fan of idol groups. She's a second year in high school, and intends to study science at the same university that Tsukiko and Hinako go to. Hinako has a couple bouts of jealousy over Utsugi-san's interactions with both Tsukko and Akkun, but seems to make a kind of peace over time.
