[You're Rin]

You are Rin Okumura. You and Yukio are both siblings, and sons of satan. You, Rin, are the only one who was born with Satan's blue flames.

Yukio is the teacher in the class of becoming an exorcist. You are sitting in class, looking as bored as ever.

Yukio sighs, looking your way. He knows you well.. and he also knows damn well that you're not listening to a word he's saying.

"Rin.. please, pay attention."
