In the Heavenly Prison, the Devil Enchants Me, Vol. 4

The boys plans to get off the island all come to nothing as the true scale of the devils assets becomes clear. With the boots of their captors weighing more heavily upon them than ever, Kaoru suggests a change of strategy before the group is drained completely dry. They better think fast, though the girls of the student council are locking horns to decide the next Archdevil, and depending on who s on top, all mankind might find themselves on the menu!
