Paradise Noise

When I dressed up as a woman and posted a music video on the internet, I suddenly became famous as a mysterious high school girl net musician (although I'm really a guy). I thought it was okay as long as I didn't show my face, but my high school music teacher, Misao Hanazono, discerned my identity, and I was blackmailed. My high school life—which should have been uneventful—was noisily and annoyingly colored by the three girls I meet through Hanazono-sensei: Rinko, the "twisted genius pianist," Shizuki, the "flower-arrangement princess drummer," and Akane, the "truant zashiki-warashi vocalist."

A boy-meets-girls story, spending all their time in love, youth, and the band!
