Harem in the Labyrinth of Another World

Transported to a fantasy realm, a teen wields an unbeatable sword and builds a chaotic harem.

When ordinary high‑schooler Michio Kaga stumbles upon a dubious browser game, he never expects to be yanked into its world. He awakens in a bucolic village, clutching a gleaming, absurdly powerful blade and a set of uncanny abilities that make him instantly overqualified for any threat. The game's exit button is nowhere to be found, and the only way forward is to accept his new reality. Embracing his role as a wandering swordsman, Michio dives headfirst into the labyrinthine dungeons that pepper the realm. Each crawl yields treasure, coin, and increasingly bizarre encounters, while his reputation as a near‑invincible champion spreads like wildfire. Along the way, he gathers a rotating cast of attractive companions—each with their own quirks, ambitions, and reasons for following the overpowered newcomer. Together they form a raucous harem, turning every victory into a celebration of excess and indulgence. The series blends high‑octane action, slap‑stick adventure, and unapologetic fanservice as Michio carves a path through monsters, bandits, and his own burgeoning desires.

This isekai fantasy centers on a protagonist who buys enslaved women to form a combat harem and explicitly sexual household. Expect graphic uncensored sexual content and a premise built on slave ownership presented without critique.
