From January to March 2009, the Shirais also made several appearances for another large promotion not usually known for female wrestling, Pro Wrestling Zero1.

After two draws and two losses, Shirai finished last in her block and did not advance in the tournament.

On June 19, 2010, the Shirai sisters formed the Triple Tails stable with fellow freelancer Kana, defeating Ayumi Kurihara, Hikaru Shida and Yoshiko Tamura in their first match together at a NEO Japan Ladies Pro Wrestling event.

As a result, the Shirais received a shot Kurihara's and Tamura's NEO Tag Team Championship on July 4, but were defeated by the defending champions.

Triple Tails returned to its winning ways on August 29, by defeating Asami Kawasaki, Hikaru Shida and Nagisa Nozaki in a six-woman tag team match.

On October 18, 2010, Shirai, working under the ring name Kitzune Nanoko, made her debut for AAA in Puebla, Mexico, where she teamed with Alissa Flash to defeat Cynthia and Esther Moreno in a tag team match.

In Mexico, both Shirais worked under cat-like masks they would only wear for their entrances in Japan.

On October 31, Shirai was renamed Kaguya, while her debuting little sister was given the ring name Oyuki.

In their first match under the new names, Kaguya and Oyuki teamed with Yuriko in a six-person tag team match, where they were defeated by Cynthia Moreno, Gato Eveready and Mari Apache.

During their stay in AAA, Kaguya and Oyuki became associates of the La Legión Extranjera (Foreign Legion) stable.

On November 7, Kaguya and Oyuki defeated Faby and Mari Apache in a tag team match and afterwards stole Faby's AAA World Mixed Tag Team Championship and Mari's AAA Reina de Reinas Championship belts.

On November 15, the Apaches and Cynthia Moreno defeated Kaguya, Oyuki and Sexy Star in a six-woman tag team match.

A week later, Kaguya, Oyuki and Jennifer Blake defeated Moreno and the Apaches in another six-woman tag team match.

This would turn out to be Kaguya's and Oyuki's final AAA appearance, which resulted in the storyline with the Apaches being dropped without a conclusion.

Upon the Shirais' return to Japan, Triple Tails made its debut as a unit for Pro Wrestling Wave on December 19, defeating Cherry, Gami and Tomoka Nakagawa in the six-woman tag team main event.

On January 29, 2011, the Shirais made their debuts for Smash, when the Triple Tails stable attacked Yusuke Kodama and Makoto after their matches, with the trio being both times chased out of the ring by Tajiri.
