Chacha Akaza

Chacha is well known for her enthusiasm and carefree personality. She is almost always seen smiling and is generally very laidback. She is shown to have very little modesty, as she is one of the few girls in the series who isn't bothered by being seen naked, instead flaunting her massive breasts whenever possible.

Chacha can be a bit extreme or drastic at times. This is shown by her putting Takeru Ooyama through life and death methods of training, as well as by her exposing Haruko Amaya's breasts in public to joke about the fact that her breasts should have a lot of milk - although she later stated she wasn't aware that Haruko wasn't wearing a bra underneath. This was not the last time Chacha touched one of her classmate's private areas--While wrestling Azuki Shinatsu, she stroked her opponent's vagina. The purpose of this touching seems to be exclusively playful.
