A boisterous, energetic athlete who would never back down from a challenge. She treats everyone around her like her best friend, especially those who play along with her shenanigans. Even the warden, Iustus, can’t escape from her unfaltering enthusiasm. She is surprisingly cooperative, but only when she is treated with the right attitude. Natsumi gets on with the majority of the prisoners, though some find her a bit overwhelming at times. As one of the more active individuals, she is often found working out or searching for people to talk to and hang out with.

Confident and cheerful.
