Volume 3 is the third novel of the Isekai Maō to Shōkan Shōjo no Dorei Majutsu series.
After being summoned to another world that looks almost exactly like the MMORPG he once played, Takuma Sakamoto now spends his days going on adventures with Rem Galleu, the black-furred Pantherian, and Shera L. Greenwood, the Elf princess, both of whom accidentally became enslaved... to him!?
Takuma, under the guise of his in-game character Diablo, hesitates, as he had previously made a promise to Rem to help her defeat Krebskulm— But he pushes through with his Demon Lord role-play and actually agrees!
"I will revive the Demon Lord Krebskulm—and defeat them!"
Now it's his Demon Lord role-play vs. an actual Demon Lord! This is the third volume of an adventure with an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!
