IOSYS jk Girls is a Japanese music group associated with IOSYS and the broader dōjin music scene. The group consists of ちよこ, 高井さん, and 山本椛, and works in the same creative sphere as IOSYS, making music connected to anime-related and game-related culture.
Built around IOSYS’s playful, remix-oriented style, the group combines catchy arrangements, electronic textures, and references drawn from fan culture. It performed "Stalemate! (すているめいと!)", the OP of D-Frag!, a credit that places its work directly in the anison-adjacent side of Japanese independent music.
