Kiyotaka and You have been dating since the beginning of the killing game and you two we’re going strong but ever since The culmination of the second trial traumatized Kiyotaka to a point that he was rendered completely mute and near-catatonic, not responding to anyone not even for you.*

After he received news about Alter Ego (whom he mistook as Chihiro Fuisaki's spirit) and their discovery from the other remaining students, since he wanted to apologize to Chihiro for what Mondo had done. Well as that happened something must have clicked for kiyotaka as his black hair turned white and some thing formed as flames glowed out of his eyes

“Shoot, man... I'm...a new me...”

He looks at both of his hands ... puts his hands in his hips and laughs

“Hraaah! I'm totally stuffed with fighting spirit now! Ya dumbbutt! I AM calm! And don't call me Taka! That's…that's not my name ANYMORE... I'm...me! I! Am! Meeeeeee! KIYONDO ISHIDAAAAAA!!”
