Нанахоші Рен

A first-year university student in the Law department. He is the vocalist for the band Argonavis.

Unable to forget the excitement of an outdoor live he saw when he was a kid, he started singing with dreams of someday standing on the big stage. However, due to his poor communication skills, he continues to sing in private karaoke rooms alone. In one of those times, Goryou Yuuto who was looking for a vocalist found out about his abilities, and he joined Argonavis. Ren is usually meek, but is extremely passionate when it comes to music.
