Hyakko (ヒャッコ, Hyakko?) is a Japanese manga created by Haruaki Katō. It started serialization on Flex Comix's free web comic FlexComix Blood on January 16, 2007. An anime adaptation has been announced.
Ayumi is shy, naive and bashful blonde. She also has a well-endowed figure which makes her popular with the boys. She quickly makes friends with Torako, Suzume, and Tatsuki. During the course of the series she gains self-confidence.
Ayumi is often the butt of jokes. Kitsune Kageyama (Torako's brother) takes notice of her and alternates between being nice to her and being mean.
