To clarify: The content is not questionable in itself, but some parents might not aproof of some of the more extreme content.

Most of the manga deserves 16 age rating. But the scene of what happened to the victim inside the Altearis spell and a scene showing the aftermath of a torture are quite brutal and in my opinion clearly fall into the adult-only category, but that's just the two scenes.
