Arisa is what is called a Ganguro or Kogal. She wears heavy white makeup and has very tanned skin, earning her the nickname "reverse raccoon". She is not a particularly good student when it comes to grades, and can be found sleeping the majority of the time, even while at school. She gets herself into hot water with Ogata, but the experience changes her for the better. Tanpopo Yamazaki helps her change from being a party girl and a "jerk magnet". Source: Wiki
