Survival in Another World with My Mistress! Vol. 2 (Manga)

BRICK BY BRICK

 

Kousuke is adjusting well to his new life as a slave in a world where his video game expertise operates as actual Crafting abilities. But it's not the magic that makes a life of servitude so cozy, it's his sexy dark elf Mistress, who puts him to work in and out of the bedroom! But it'll be more out than in-and-out as Kousuke must develop his power and grow strong enough to build a giant bulwark around the elven lands, or everyone may die at the hands of an overwhelming invasion force!
