After being sidelined for over a year, Shibutani returned to Pro Wrestling Wave on August 28, 2011, losing to Akino in her return match. On September 4, Shibutani and Cherry entered the 2011 Dual Shock Wave tournament as the "Classic Gals", but were eliminated in their first round match by Ayumi Kurihara and Kana, who went on to win the entire tournament. On October 27, Shibutani represented Wave in Sendai Girls' Pro Wrestling's Joshi Puroresu Dantai Taikou Flash tournament, a single-elimination tournament, where different "joshi" promotions battled each other. In their first round match, Team Wave, which also Gami, Moeka Haruhi, Toshie Uematsu and Yumi Ohka, was defeated by Team JWP of Command Bolshoi, Hanako Nakamori, Kaori Yoneyama, Kayoko Haruyama and Leon. Shibutani finished off 2011 with a big singles win over Yumi Ohka on December 11 with her new finishing maneuver, later named "Time Machine ni Notte" ("Ride the Time Machine"). On January 4 at Wave's first event of 2012, Shibutani picked up another big singles win over Wave Tag Team Champion Ayumi Kurihara. On February 1, Shibutani, Kurihara and Mika Iida came together with Kana and Mio Shirai to form the White Tails stable, named in reference to Wave's top villainous alliance, Black Dahlia. On April 30, Shibutani took part in Toshie Uematsu's retirement match, a tag team match, where she and Moeka Haruhi were defeated by Uematsu and Ran Yu-Yu. On May 16, Shibutani entered the 2012 Catch the Wave tournament, taking part in a round-robin block made up members of White Tails. In her opening match of the tournament, Shibutani was defeated by Ayumi Kurihara. In her second match on May 29, Shibutani wrestled Kana to a fifteen-minute time limit draw. On June 17, Shibutani wrestled her second time limit draw of the tournament with guest White Tails member, Wrestling New Classic (WNC) representative Syuri. Shibutani finished her tournament on July 1 with a win over Mio Shirai, failing to advance from the block. On July 16, Shibutani and Shirai unsuccessfully challenged Gami and Tomoka Nakagawa for the Wave Tag Team Championship in a three-way elimination match, which also included the team of Moeka Haruhi and Yuu Yamagata. On September 1, Shibutani made her first appearance for Ice Ribbon in four and a half years, defeating Miyako Matsumoto in a singles match. On September 23 at "Ribbon no Kishitachi 2012", Shibutani took part in a three-way match, where Hailey Hatred defeated Neko Nitta to capture the Triangle Ribbon Championship. Two days later, Shibutani entered the 2012 Dual Shock Wave tournament alongside Syuri. After wins over Shidarezakura (Hikaru Shida and Yumi Ohka) and 1st Impact (Makoto and Moeka Haruhi), and a loss against Kurigohan (Ayumi Kurihara and Mika Iida), Shibutani and Syuri finished tied at the top of their block with Shida and Ohka. On November 16, Shibutani and Syuri defeated Shida and Ohka in a playoff match to advance to the finals of the tournament, where, later that same day, they were defeated by Makkurokorosuke (Misaki Ohata and Tsukasa Fujimoto). On June 10, Shibutani made her debut for Wrestling New Classic, teaming with Yuu Yamagata in a "Wave offer match", where they were defeated by Gami and Moeka Haruhi. From May to July 2013, Shibutani took part in the 2013 Catch the Wave tournament, where she finished her round-robin block with a record of three wins and three losses, advancing to the knockout stage after defeating Cherry, Hikaru Shida and Mio Shirai in a playoff match on June 28. On July 15, Shibutani was defeated in the first round of the knockout stage by JWP Joshi Puroresu representative Arisa Nakajima. She, however, claimed third spot in the tournament by defeating Syuri, Tomoka Nakagawa and Yuu Yamagata in a four-way elimination match later that same event.
