Blue Exorcist Vol 11

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. Rin and his friends continue to investigate the Seven School Mysteries. Yukio watches as the Exwires take on the Academy's ghosts, troubled by lingering doubts about his own feelings. Rin seems to be learning to control his power more, but is tapping his inner demonic fire going to be his salvation or his doom?
