[1] Chie first competed as a decorated amateur wrestler in high school, reaching third place in the Junior Olympic Cup.

[1] In 2006, after graduating from Shigakkan University, Ishii was signed by Dream Stage Entertainment and moved to the Hustle promotion.

In 2007, she feuded with Monster Army member Giant Vabo and allied with model Hitomi Kaikawa, though being defeated in several occasions.

As Kushida focused in his confrontation with Ray Ohara, Chie then formed a tag team with the new HUSTLE Army recruit, her kohai KG.

Chie won their first match and badmouthed her after the bout, but one month later, KG retaliated by beating her in the rematch.
