Aooo is a Japanese rock band formed on August 24, 2023, and composed of Ishino Riko, Surii, Tsumiki, and Yamamoto Hikaru. Blending J-pop and rock, the four-member project brings together creators with distinct backgrounds and has quickly become a name to watch for listeners interested in contemporary Japanese band music and anime-related songs.
The band’s anime visibility increased in 2025 through WITCH WATCH, which previewed Aooo’s ending song in March and later released the ending song music video in August. That association makes Aooo especially relevant for searches around anime songs, anime endings, and modern anison-adjacent rock acts.
