Hiroyo Matsumoto
On 8 March, ROH's website announced the signing of three joshi wrestlers from the all-female Japanese promotion S-Ovation would debut over the weekend; Hiroyo Matsumoto, Ayumi Kurihara, and Tomoka Nakagawa would all wrestle after appearing at ROH's sister promotion Shimmer Women Athletes. At Final Battle 2010, Shimmer stalwart Serena Deeb teamed with Sara Del Rey to take on her enemy Daizee Haze who had picked Amazing Kong as her partner. On 28 March, ROH announced that the team of Deeb and Del Rey would wrestle Matsumoto and Kurihara on the first day of the event. On the second day, Matsumoto and Kurihara challenged Haze and Nakagawa for the Shimmer Tag Team Championship, having won them six days previously at "Volume 40".
