Муто Тамакі

She is a university student who lives in the same building as Shinkurō. She can be described as a very flirtatious person and her advances are noticeably more aggressive with Shinkurō. She says she is very knowledgeable in the ways of love but doesn't include her own experiences as she has a hard time keeping a boyfriend. She has grown fond of Murasaki and teaches her all kinds of perverted terms, much to Shinkurō's objections. Tamaki is an instructor at a karate dojo, and is very formidable at fighting, with notable feats such as stopping a punch with just two fingers and standing on par with Yūno at full strength.

In the anime, she is just a normal university student looking for love and also possess fighting skills.
