"When Shiemi confronts her old nemesis Amaimon, the demon king of earth doesn't understand just how powerful Shiemi has become. But for Shiemi to achieve her destiny, she also needs to realize her own strength! Back in Assiah, Satan and his minions square off against Mephisto and the Knights of the True Cross to determine the fate of the world. After receiving some enchanted power-ups, the Exwires prepare to enact their battle plan. Rin himself is part of the vanguard that aims to engage the enemy head-on. The time has come for Rin to fulfill his promise to defeat Satan, the King of Demons!"--Back cover.

"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.

Rin and his friends travel to Kyoto in search of a thief who has stolen a powerful artifact from the grounds of the True Cross Academy and taken a child hostage, but their awareness that Rin is the son of Satan threatens to drive a wedge between him and his classmates.

Exorcist Rin Okumura continues to try to control his demonic powers as distrust swirls around the heads of the various Myodha temple families, and he receives a letter that reveals information about his past.

"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. Isumo has found some peace and a new sense of purpose, but serious questions about Renzo Shima's betrayal still need to be answered. It's not an easy thing for Ren and his friends to hear that they are just pawns in Mephisto's schemes, but the game is on!"--Back cover.

"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?" --.
