Kessoku Band ( Naughty Jail )

Kita is an outgoing and optimistic guitarist who initially struggled with her instrument but improved after reconciling with Ryo. Ryo, on the other hand, is quiet and has few friends but enjoys playing bass and encouraging others. Nijika is kind-hearted and supportive while working at a live house managed by her sister. Hitori suffers from social anxiety but finds solace in playing guitar; she later joins Kessoku Band where she gradually overcomes some aspects of her introversion through supportive friendships within the group members.
