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

Zagan is feared as an evil mage, he is awkward and has a sharp tongue, and once again had to put down thieves that encroached on his territory when he was researching that morning. In a dark auction, he finds a white slave elf, Nephie, who holds a peerless beauty. Falling in love with her at first sight, he uses his fortune to buy her, but as poor as he is socially, he doesn't understand how to connect with her.
