Ayumi Kurihara
On February 3, 2011, Nozaki wrestled her first match since the folding of NEO, teaming with Aya Yuki at a T-1 event, where they wrestled Futami President and Great Sasuke to a no contest. On April 17, Nozaki made her debut for former NEO worker Kyoko Inoue's new World Woman Pro-Wrestling Diana promotion, losing to Nanae Takahashi in a singles match. After suffering another loss to Yumi Ohka on April 24, Nozaki picked up her first Diana win five days later, defeating Sareee. On May 1, Nozaki was defeated in a singles match by Gami. The following day, Nozaki made her debut for Gami's Pro Wrestling Wave promotion, entering the 2011 Catch the Wave tournament and defeating Yumi Ohka in her opening round-robin match. On May 4, Nozaki was booked for a Diana event, but ended up no-showing the event. Six days later, Diana publicly fired Nozaki for a "serious breach of contract". Nozaki quickly apologized for her actions and revealed that she was considering retiring from professional wrestling as a result of her firing. On May 17, Nozaki continued her Catch the Wave tournament with a win over Mio Shirai, however, she would lose her two remaining matches against Misaki Ohata on June 15, and against Ayumi Kurihara on July 6, and, as a result, finished third in her block and failed to advance from her block. Nozaki wrestled her final Wave match on July 24, when she, Bambi and Yumi Ohka, all representing the villainous Black Dahlia stable, defeated Ayumi Kurihara, Ryo Mizunami and Sakura Hirota in a six-woman tag team match. Afterwards, Nozaki announced that she was taking an indefinite break from professional wrestling to heal her shoulder. Nozaki underwent surgery on her shoulder on February 2, 2012.
