Blue exorcist

"The Knights of the True Cross and the Exwires have fully engaged Satan on all fronts. Rin confronted Satan head-on, and despite being blown apart, Rin's own demonic nature allows him to reform and stay in the fight. Meanwhile, Shemihaza begins a ritual to crystallize and trap Satan--a ritual that Shiemi will play a crucial part in. When Satan takes his transformation to the next level, even time itself warps under his power, showing everyone a future they could never have imagined"--Back cover.
