Isekai Maou to Shoukan Shoujo no Dorei Majutsu Ω

Diablo continues traveling with Rem and Shera, still hiding severe social awkwardness behind the arrogant Demon Lord persona he knows how to perform. While testing new magic, he rescues High Priest Lumachina from assassins connected to her own church. She interprets his overwhelming power as divine intervention and becomes convinced he is a god. Diablo chooses to protect her as she searches for someone trustworthy inside an institution corrupted by its own leadership. New companions join the group, and the journey turns into a confrontation with powerful religious and political figures. Saving Lumachina may require Diablo to maintain an act even larger than the identity he invented for himself.
