Pro Wrestling Wave
On August 26, 2007, Shibutani worked the first ever event held by Pro Wrestling Wave, a promotion founded by Gami and JDStar alum Yumi Ohka, losing to Kaoru in a singles match. During the next months, Shibutani continued working both beside and against Kaoru and, on September 25, picked up her first win in Wave, when the two defeated Command Bolshoi and Dark Mask Bolshoi, the masked alter ego of Gami, in a tag team match. Five days later, Shibutani and Misaki Ohata defeated Arisa Nakajima and Cherry in Shibutani's final Wave match before going on a learning excursion to Mexico.
