CPCP-004 The shyest petite-chested girl in Japan, Petchako, is a promising talent with world-class dance skills and works as a backup dancer for a famous artist.

She lacked confidence and felt shy about being in front of others. But once the music started, she seemed like a different person, breaking into sharp, energetic dancing. She was shy around strangers, but once she got used to someone, she became very friendly and charming. She also seemed quite innocent in romantic matters, and although her small bust appeared to be a source of insecurity, she was very sensitive and responsive.
