Siam Shade
With the end of Siam Shade, Hideki didn't want people to always compare his new band with the old one when he was singing. That's why he drew back to the position behind the keyboard at first and later on left Acid completely in June 2005 so that the band were able to go their own way. Furthermore, he says that this group is his pride and that he'd like to see them in Tokyo Dome one day.
