|Manga Debut||Chapter 89|
According to an old book that Idamaria read in preparation for her Exorcism Exam, the Apocalips is a special type of drug that can counter any poison with its own, and has saved people on the verge of death through history. Seruma adds that the book's information isn't complete, as he read that it was a medicine powerful enough to revive the deceased, but with "terrifying side-effects and after-effects".
- Even in the demon world, the Apocalips is a rare sight.
- Despite its existence being known by the Vatican, the Apocalips isn't even mentioned on the standard Exorcism Exam.
