Blue Exorcist. 15

Rin and his exorcist classmates are caught in a secret war against the forces of darkness. Raised by Father Fujimoto, a famous exorcist, Rin Okumura never knew his real father. One day a fateful argument with Father Fujimoto forces Rin to face a terrible truth-the blood of the demon lord Satan runs in Rin's veins! Rin swears to defeat Satan, but doing that means entering the mysterious True Cross Academy and becoming an exorcist himself. The operation against Professor Gedoin's diabolical Dream Town Inari is just the opening round in the growing conflict between the Knights of the True Cross and the Illuminati. As both sides regroup and lay plans for the future, the Exwires try to come to terms with what has happened. Though Izumo finds some peace and a new sense of purpose, serious questions about Renzo Shima's betrayal still need to be answered. It's not an easy thing for Rin and his friends to learn that they have become pawns in Mephisto's schemes, but the game is on!
