Tsumiki Miniwa

Tsumiki has floor length blue hair tied in a very low ponytail with a white scrunchie, and purple eyes.

She forms cat ears and a cat tail from time to time, often when she sees Io. At all other times, though, she has a large, swirly ahoge on the top of her head. She usually wears the Nekoge Prefectural High School uniform and is shown wearing the version with a sweater during the winter (as opposed to wearing the winter version with a jacket). She is aggressive to the point of violence towards acts of teasing. This is exemplified when the teasing is about Tsumiki and Io's relationship and interactions. She often tries to hide her feelings and comes off as distant, and rarely smiles, compared to the rest of the cast. She cares for her friends, however, as it is shown where she forgets her chocolates, but tells Hime to give hers anyways, since Hime put in the effort.
