Chie Ishii

In 2007, she feuded with Monster Army member Giant Vabo and allied with model Hitomi Kaikawa, though being defeated in several occasions. The feud ended in February 2008, when Chie defeated Vabo in a singles match. As Kushida focused in his confrontation with Ray Ohara, Chie then formed a tag team with the new HUSTLE Army recruit, her kohai KG. However, during a tag match, KG accidentally kicked Chie in the head, causing the team to lose. At the next show, the two were teaming up again when suddenly Chie turned on her and mercilessly attacked KG, causing the two to feud.

Chie first competed as a decorated amateur wrestler in high school, reaching third place in the Junior Olympic Cup. In 2006, after graduating from Shigakkan University, Ishii was signed by Dream Stage Entertainment and moved to the Hustle promotion.

She debuted in 2005 as a member of the face stable Hustle Army, going under the name of Banzai Chie (＼(^o^)／チエ , \(^o^)/ Chie) , which was unique for using a Japanese emoticon meaning "banzai". She was introduced as an apprentice to Tajiri, serving as his valet, and later teamed with Tajiri's next protégé, Kushida.
