Nagisa is a member of the group RONDO.

Nagisa is a guitarist who grew up in a rock music-loving family. She came across the club where Aoi performed as a DJ when she was searching for a place to practice, and often visits Hiiro's house as well. She can be shy around strangers, but honors friendship more than anything else.

At the same time, she can be noticeably open or even playful with her close people, whom she trusts enough. Notable examples include her friendly behavior with Saori during her unit's spring trip, or teasing Tsubaki about her tsundere side.
