Aooo is a Japanese rock band formed on August 24, 2023, composed of Ishino Riko, Surii, Tsumiki, and Yamamoto Hikaru. Blending J-pop and rock, the group emerged with a lineup that brings together four creators under one project, making Aooo relevant to listeners who follow contemporary Japanese band music and anime-related songs.
In 2025, Aooo gained additional attention through WITCH WATCH, which previewed the band’s ending song in March and later shared the ending song music video in August. That anime connection gives Aooo a clear place in the current Japanese music scene for fans looking for bands tied to anime openings, endings, and modern anison-adjacent releases.
