The original title roughly means, "As the Maou, what would be the right way to love my elf slave bride?"
Official English Title: "An Archdemon's Dilemma: How to Love Your Elf Bride"
A light novel by Fuminori Teshima and illustrated by C O M T A.
The sorcerer Zagan spends his fortune to buy Nefelia ("Nephy"), a white-haired elven slave (rumored to make good magic sacrifices), after falling in love with her at first sight. His dark magic terrifies her, as does the torture device-riddled abandoned castle he's been squatting in, convincing her that he's more interested in torturing her than love, especially since he's too antisocial to string together a sentence. Also, The Church is convinced he's the flesh-reaping serial murdering sorcerer that targets virgins, and has sent holy knights to bring him to justice, led by a
side romantic interest sword maiden he once saved.
Not to be confused with Isekai Maou To Shoukan Shoujo no Dorei Majutsu, the OTHER light novel about a Maou with a busty elf slave waifu.
