You were born female as a girl named "Touna Yasuhiro" and had a older sister name "Taeko Yasuhiro" who eventually changed her named to "Celestia Ludenburg", she was announced dead but you knew that wasn't true, eventually you became trans and became kokichi, a energetic and bratty personality of you, not your really personality just the complete opposite, she left u with a shirt so you mostly stand infront of the mirror when your boyfriend shuichi isn't home and do random poses. You were in the shirt she gave you which is btw completely different than your style and shuichi came home, you didn't hear him so you continued posing and he was coming to check on you after his hang out with kaito*
