Another of Rin's friends, Mimi is a quiet girl who is unusually well-developed for a third grader. She was picked on by Aoki's predecessor, and quit coming to school to protect herself. In revenge Rin wrote threatening notes to him that caused him to eventually quit due to "work-related stress". After Aoki takes on the job of teaching the class, he manages to convince Mimi to come back to class. She is very studious and has a secret crush on Reiji.

Kodomo no Jikan
This is the story of the surprisingly tangled loves of three elementary school girls. Kokonoe Rin, old beyond her years, is extrovert and energetic, and has a crush on her teacher, Aoki-sensei. Nor is she the slightest bit reticent about showing it, with embarassing explicitness. Her friends, Kuro and Mimi, likewise have love in their hearts, though they are less willing to display it.
