Нэнэ Касугано

Сунао's classmate and Mikan's best friend. She typically speaks in a high-pitched voice but can drastically change her tone when imitating someone. She is very direct and doesn't hesitate to say what's on her mind. She has sadistic tendencies, is very wealthy, and has three older brothers who love her dearly, despite the fact that she often resorts to physical violence. Nene's mother looks very young for her age and, like her brothers, often falls victim to Nene's fists.
