Rakuen Noise

A male high school student gains online fame by posting music videos while disguised as a girl. He avoids public appearances to maintain his secret, but his music teacher discovers his identity and uses it against him. Through the teacher, he meets three girls: a pianist known for her unconventional talent, a drummer with a background in flower arranging, and a vocalist who skips school frequently and is likened to a zashiki-warashi. His previously quiet school life becomes chaotic as he interacts with them, spending time focused on music, relationships, and youth.
