The primary antagonist during the last volumes of the manga. The CEO (real name unknown due to last 6 volumes not translated) is the head of a powerful corporation, she is not ashamed to flaunt her power and often has her workers bowing before her.
As is with seemingly every other female in the manga she apparently likes Densuke too, although she looks older than him . Evident when she tied him naked to her bed,letting him in between her boobs and kissing him.
Near the end of the manga is is revealed that she was not always the way she is, but became so after something tragic happened to her as a teenager.
