In September 2007, an audience of 13,000 participated in a memorial Budokan concert. There were nine screens set up where many showed previously unseen footage of Izumi Sakai. A first single after she died called "Glorious Mind" was played. This was a song which Sakai recorded before her hospitalization. This song was used for the opening theme song of the anime series "Case Closed". It was not complete at the time of Sakai's death, but the chorus footage was complete. Extra minutes where she was singing in English were incorporated from a previously unrelated and unreleased song as well.
