Nagisa Shiratori

Gin's number one best friend, and a member of the Silver Class at Fujiwara Academy. He and Gin have been friends since childhood, and he affectionately calls him "Gin-chan." Nagisa has a rather feminine and petite appearance, so he's prone to crossdress at times. Kirara mistook him for a girl at first, and assumed that Gin was cheating on her with him.
