Aooo is a Japanese rock band formed in Tokyo in August 2023. It consists of Riko Ishino, Surii/Threee, Hikaru Yamamoto, and Tsumiki. The band made their major-label debut with Echoes and Sony Music Entertainment Japan in October 2024 with their debut studio album Aooo.

History

Before the formation, Riko Ishino is a former vocalist of the rock band Akai Ko-en and Idol Renaissance; Surii/Threee and Tsumiki are Vocaloid producers, the latter is also a member of the duo Nomelon Nolemon; Hikaru Yamamoto is a supporting band member of Yoasobi and Momoiro Clover Z. Surii, Yamamoto, and Tsumiki decided to form Aooo and invited Ishino to join as the vocalist. The name refers to the members' blood type, being one A and three O. Aooo's formation was announced on August 24, 2023. The band debuted their live performance as a special guest for rock band Awkmiu's concert Gift Shop on September 16 at Shibuya Eggman, Tokyo, where they performed their original song "Apathy" for the first time.
Aoo originally planned to issue their first demo EP Demooo on March 6, 2024, at Live Natalie "Aooo × Hakubi × Chirinuruwowaka" concert at Duo Music Exchange in Shibuya. Still, it was postponed due to a malfunction at the manufacturing plant. However, the band prepared hand-burned CD-Rs of the demo for fans instead. Demooo was finally released on April 29 at the Electric Restaurant 127 show with Chakura. The next day, Aooo launched their YouTube channel.
In September, the band was moved to Sony Music Entertainment Japan's record label Echoes, and announced their major-label debut studio album Aooo. It included all tracks from Demooo and was released on October 16. To promote the album, they held the free concert Flash!!!! in Kabukichō on October 18, as well as embarking on their first concert tour, the Bowwow Live Tour, from December 2024 to January 2025. In January 2025, Aooo made their first television appearance at Buzz Rhythm 02. On April 16, the band released their first EP Fooocus. It was preceded by the single "Fragile Night", and included the ending theme for anime adaptation of manga series Witch Watch, "Find Your Magic". "Fragile Night" later served as a theme song for TX Network's drama series Ryōsan-gata Ruka.
Between July and September, Aooo released three standalone singles: "Yankeee", "Geeek", and "Crazzzy". In support of Fooocus, the band embarked on the second concert tour, the Bakubaku Live Tour, from September to October, and held the one-off concert, Bazoooka, at Tokyo Garden Theater on December 6. Following the concert, the band released "Star Sign" as the lead single from their untitled second studio album. It is set to be released on June 3, 2026, and supported by the Ringring Live Tour.
