Hajime Ohara
On August 2, 2012, Nozaki made a surprise debut for Wrestling New Classic (WNC), the follow-up promotion to Smash, attacking Makoto with a "shinai" and aligning herself with Hajime Ohara. The appearance marked Nozaki's first professional wrestling appearance in thirteen months. Dubbing herself "Nozabitch", Nozaki began working in WNC as a villain for the first time in her career, adopting the "shinai" as her signature weapon. The following day, Nozaki managed Ohara at another WNC event, where he was victorious over El Hijo del Pantera in a singles match. Nozaki made her in-ring debut for WNC on August 30 in Korakuen Hall, defeating Makoto via referee stoppage with the sleeper hold. The two had two rematches the following day days; Nozaki was also victorious in both of them with the sleeper hold. During the weekend, Nozaki and Ohara were also joined by rookie Jiro Kuroshio. On September 17, Nozaki earned yet another sleeper hold win over Makoto in a tag team match, where she teamed with Kuroshio and Makoto with Yusuke Kodama. On October 19, Nozaki, Ohara and Kuroshio named their stable "Kabushiki gaisha DQN" On November 27, Nozaki returned to Pro Wrestling Wave, teaming with Hikaru Shida in a five-way tag team match, which was used to determine the number one contenders to the Wave Tag Team Championship and won by Makoto and Moeka Haruhi. The following day, after receiving a first round bye, Nozaki entered the WNC Women's Championship tournament in the semifinal stage, defeating Kana with help from Jiro Kuroshio. Following the upset win, Nozaki began using Kana's nickname, "World Famous". Prior to the final match, Nozaki began making appearances wearing crutches, claiming that she had broken her leg, having fallen over drunk. During the tournament final on December 27, Nozaki revealed that her supposed injury had been a bluff as she started the match off by attacking her opponent, Syuri, from behind. Despite this, Nozaki was eventually defeated, suffering her first direct loss in WNC. Nozaki suffered her second loss in a row at WNC's first event of 2013 on January 4, when she was defeated by Makoto. On January 25, Nozaki was, for the second time in her career, sidelined with an orbital floor fracture, suffered during a six-person tag team match, where she, Hajime Ohara and Jiro Kuroshio defeated Lin Byron, Yo-Hey and Zeus. While Nozaki was recovering from her injury, Hajime Ohara legitimately quit WNC, effectively ending DQN K.K.
