Naoko Mifune

Naoko Mifune is a classmate of Tomo Aizawa and the best friend of Chiyomi Ogawa. She has dyed-red hair that is tied in a ponytail where it is pulled to the back of her head with bangs that split in the center of her forehead, grey eyes and freckles under each of her eyes. Her appearance was much more rule-conforming during middle school with straight black hair and a neat uniform.

Naoko is shown to be an easily jealous girl, as shown by how she and Ogawa feel about Tomo's relationship with Kousuke Misaki-senpai. She was, however, quick to change her feelings about Tomo when she said she'd get them closer to Misaki.
