Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?

Zagan, who is dreaded as a malevolent sorcerer, is socially inept and possesses a biting wit. Once more, he had to deal with intruders that invaded his domain while he was engaged in research that morning. During a shadowy auction, he encounters a stunning white slave elf named Nephie, whose beauty is unmatched. Instantly smitten, he spends his wealth to acquire her, yet his lack of social skills leaves him clueless on how to bond with her.
