Volume 4 is the fourth novel of the Isekai Maō to Shōkan Shōjo no Dorei Majutsu series.
After being summoned to another world similar to the game he used to play, Diablo lives a tumultuous life in this new world after he finds himself the unwitting master of Rem the Pantherian and Shera the Elf; and now, even the Demon Lord-turned-young-girl Klem obeys him!
One day, Diablo ends up rescuing a holy woman who was being pursued by a Paladin, and she turns out to be the most important person in the Church. Befriending her, Diablo and the others act as her escorts until they reach Zircon Tower deep in the Demon Lord’s territory.
After arriving in a new town, more difficulties arise, ultimately culminating in the appearance of a gargantuan monster attacking them!
Is the self-proclaimed Demon Lord becoming a guardian deity for a follower of the Gods!? This is the fourth volume of the adventure of an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!
