異世界迷宮でハーレムを

Michio Kaga, a listless high school student, clicks through a strange browser game and wakes up in a fantasy world with cheat-level stats and a sword far above his station. There is no way to log out, so he makes the most of it: he clears labyrinth floors for money and buys a wolf-eared slave girl named Roxanne as his first party member. Between expeditions the two grind levels, upgrade their gear and settle into a domestic routine.
