Blue Exorcist

EP 2 Gehenna Gate

Rin is thrown into turmoil when Shiro tells him that he's the son of Satan! But this doesn't stop the demons from unleashing a brutal attack. Warning him that he must never draw it, Shiro gives Rin the Koma Sword, and hides him in the monastery basement. Outside, a fierce battle begins - it's Shiratori, who's morphed into a giant demon, versus the exorcists! Just after Shiro manages to end the battle, Rin turns on him in a rage: ""Don't act like you're my father!""
