Sakiyama Kaori

A wanna-be future model (later a female wrestler) with an obsessive one-sided rivalry with Maki. She later becomes a moderately good fighter, and accomplishes things by sheer force of will and determination. She is loud and over dramatic, and during extended fights is essentially a Berserker powered by her own rage, and she will not admit defeat unless violently knocked out. A running gag in the show is how most characters refer to her by her full name in a dramatic fashion, probably due to her tendency to do the same. When enraged, her appearance has been compared to the Devilman. Due to a childhood "accident", she's deaf in her right ear. (Source: MAL)
