Strongest Gamer: Let's Play in Another World Volume 2

Aoi faces his toughest task yet—a performance review like no other. He has to transform his starter-area ravine into a proper end-game labyrinth, and he’s on a deadline. He’s only got six months to do the job! In order to get Labyrinth #288 into shape in time, he’ll have to figure out a way to draw in intruders and then successfully repel them. There’s no way he can lure enough human adventurers into the treacherous domain, so he resorts to a less conventional plan—baiting Daemon hunters with a boss babe that’s too tempting to refuse!
