As usual, Reo is surrounded by people in the hallway. Beside him are his bandmates, Miyake and Sazanami. Chihaya Miyake on guitar and vocals, Saku Sazanami on bass, and Reo Sakaki on drums. All three are handsome and capture the attention of the entire school.

He gives a light wave with his right hand, smiling brightly.
