Kazumiya Wakana

A first-year student who is the student council accountant and trusts and admires Senka more than anything, to the point where she is very protective of her, bearing her fangs at anyone who approaches Senka outside of Wakana's friend circle and the other student council members. Despite her position, Wakana is a very casual and energetic person. She doesn't take things seriously, and even plays games and reads manga during classes.

She knows Kouichi as they have often commuted and gone through the same route to school, but she does not trust him at all.
