About Kawabe Chieko:
Chieko fell in love with music, and in high school she decided to take vocal training and dance lessons. When she was just 12 she debuted as a talent at her agency. She became an exclusive model for the magazine Love Berry and began working doing promotional work as well.

Cheiko is interestingly enough the only cast member on PGSM to be involved in the musicals as well, playing Sailor Mercury from late 2000 through 2001. (she quickly became the fan-favorite actress for that role)

As Naru, Cheiko brought perhaps a bit more sensibility to the role. While still good-hearted, the Naru that Kawabe portrayed had a more level head on her shoulders, and while she still was tangled up into more than a few Dark Kingdom incidents, she was shrewd enough to notice when things were not on the level. This is even evident in Act 1 when she accuses the youma of not being her mother because she is acting peculiarly. In PGSM, Naru even discovers that Usagi is Sailor Moon.

Kawabe has had some solid successes in her career. Her first single took off and became the theme song for the anime Elfen Lied, and another song she released became the ending theme song to Otogizoshi. She also sang the theme song for the Japanese version of Lizzie Maguire. Following all of these singles she released her only full length album (as of Oct 2009), Brilliance, which became a popular success. The last musical release she had was in 2006 with the single "Sakura Kiss", which became the theme song to the anime Ouran High School Host Club.

Chieko more recently is hosting a weekly show on a popular radio station in Harajuku district and continues to model. On August 8, 2008, her name changed to Ochi Chieko when she married Ochi Masato, a producer.
