Ado performed the Rhythm Heaven Groove song “Love me forever!”. The track was written by Tsunku specifically for Ado and became one of the game’s headline guest-vocal songs.
Ado is a Japanese singer known for a powerful, highly expressive voice and for maintaining a deliberately private public identity. Her breakthrough single “Usseewa” established her as one of Japan’s most prominent modern pop vocalists, while her work on anime and film soundtracks broadened her international audience.
The song is especially notable because Tsunku said he had long wanted Ado to sing for Rhythm Heaven. The other options are major Japanese singers too, but Hikaru Utada, Aimer, and LiSA are not credited as the vocalist for this Groove track.
