The song was the last song recorded by
Izumi Sakai before she died. Although the song was not complete at the time of Izumi Sakai's death, the chorus part had been recorded with assistance of
Yuri Nakamura from Japanese pop band
Garnet Crow. The extra minutes recorded in
English were from another unrelated and unreleased song. The song was used as a 21st opening theme song of
Detective Conan. ==Oricon Charting==
