“I wonder which you are. A human...or a demon? One day you will have to decide.”

“I'm not a human or a demon anymore. In which case.. I'll have to be an Exorcist!”

“Yukio!! I swear to God I'll surpass you!! Just you watch!”

“I'm an idiot like you said, so whatever you say about me doesn't matter, but you know... Don't you dare point a gun at your own brother!”

“You better peel your eyes out so you don't miss a thing, alright!”

“From.. from now on.. I will protect my brother in father's stead.”

“Tienes que usar esa terrible fuerza que tienes por alguien, por algo, por lo que sea que te haga mejor persona.”
