for other keyboardists. In the end she found no one who was better than Izawa, and Sheena decided to invite him to join. He assumed the stage name of Ichiyo Izawa during his time with the band. The search for a new guitarist proved more difficult. Sheena approached several guitarists as potential members, but was turned down by all of them, possibly because they disliked the idea of being considered her "backing band". At worst, she planned to choose a different guitarist each time without having a regular guitarist. However, when the other members listened to the first Tokyo Jihen album Kyōiku demos, the situation changed. All of them were pleased with the demo session guitarist and asked Sheena his name.

Members' activities outside Tokyo Jihen (2008–2009) The music video for "Killer-tune" won the Best Technical Works Video category in the March 15, 2008 Space Shower Music Video Awards 08 by Space Shower TV.
