Tsumiki Miniwa
Tsumiki Miniwa is Acchi Kocchi's major female heroine. She is also one of the best anime cat girls. She attends Nekoge Prefectural High School, where she studies alongside Io Otonashi, Mayoi Katase, Hime Haruno, and Sakaki Inui. Long hair always draws attention, and it's apparent that a girl will be admired if her hair is unusually long. Tsumiki has long purple hair that compliments her delicate body. If you believe this girl is incredibly polite and won't say anything even if you mess with her, you are mistaken, my friends!
Tsumiki, for the most part, is reserved and peaceful. She can, however, be aggressive to the brink of violence, especially when she is the target of Sakaki and Mayoi's taunting. This is generally exacerbated when the teasing is about Tsumiki and Io's relationship and how they interact with one other.
Although Tsumiki Miniwa tends not to display her emotions, which makes her appear distant, and she has been shown to rarely smile in comparison to everyone else around her - she genuinely cares about her friends. In the manga, she is considerably more of a kuudere, frequently striking Mayoi over minor teasings and appearing to "bite" Io's head a lot more than she does in the anime.
