With Diablo learning of a ritual passed down by the Dark Elves that may be able to remove the remnants of the Demon Lord's soul still slumbering within Rem's body, he tags along despite her insistence to solve her personal problems on her own (out of concern of course—it has nothing to do with the Dark Elves having gigantic breasts according to the game! R-Right...?)

But a tragic injustice they had suffered in the past looms over them, making the Dark Elves hostile to the other races. Diablo steels himself for battle as bow and arrow are nocked against him:

"Your petty grudges do not concern me. Obey my orders!"

Meanwhile, Shera must marry a male Elf to become the Kingdom of Greenwood’s new queen?!

Will the Elven Kingdom be overthrown by Diablo's great magic?!

This is the seventh volume of the adventure of an earth-shakingly powerful Demon Lord (or at least someone who acts like one) taking on another world!
