Mio Shirai
On September 23, Ohka entered the 2014 Dual Shock Wave, teaming with Ice Ribbon's Tsukasa Fujimoto, playing off the two's management roles in their respective home promotions. They were, however, eliminated from the tournament in the first round by Plus Minus 2014 (Mio Shirai and Misaki Ohata). On October 5, Ohka made a special appearance for All Japan Pro Wrestling, teaming with Shuu Shibutani in a tag team match, where they defeated Kana and Mika Iida. On July 20, 2015, Ohka became the first two-time winner of Catch the Wave by defeating Mika Iida in the finals of the 2015 version of the tournament. As a result, Ohka earned a shot at the Wave Single Championship, but was defeated by Ayako Hamada on August 9.
