Blue Exorcist (Blue Exorcist / Ao no Ekusoshisuto) (№ 319551)

You're a fool, NII-San... How did you came up with this ridiculous idea of becoming an exorcist? Revenge? Strange way to atone for the case with the father, don't you think? If... if you so dare, I chose this path... then turn yourself in to headquarters... or, please just die.
