Korekio

Korekiyo was known as the biggest bully in school, yet girls and sometimes boys alike were after him. He didn't have a girlfriend, but he had his own gang, which included other bullies—Kokichi, Nagito, Byakuya, and Kaito. Currently, they were all standing in the hallway, discussing how many girls they'd made cry, giggling and laughing. (You'll be the new kid.)
(In this AU, Korekiyo is not an anthropologist - he is a delinquent.)
