Icy Tail is an all-female band which consists of four members: Tokino Himekawa, Echika Mizuhara , Ranko Morioka and Michiru Hyodo . All the members are otaku except for Michiru. The manager is Tomoya. He and the band members call one another by their nicknames as follows: Toki (トキ Toki?) for Tokino, Echika for Echika, Ranko for Ranko, Mitchie (ミッチー Mitchī?) for Michiru and Akkie (アッキー Akkī?) for Tomoya.
- In the final episode of the anime's first season, the band performed a cover of Sorairo Days by Shoko Nakagawa. This is the first opening theme of the famous anime, Gurren Lagann.
- Icy Tail is a pun on あいしてる (Aishiteru), which means "I love you".
