Description

Mizuki Takase is the protagonist's friend since junior high and eventually end up in the same college together. She is energetic and athletic with long red hair in a side ponytail. She's hostile and skeptical towards otaku and doujinshi, and is initially opposed to Kazuki's new activity. However, she's also torn by Kazuki's expressions of satisfaction with the doujinshi process, and worries that it leaves less time for them together.
