The Otherworlder, Exploring the Dungeon, Vol. 1 (light novel)

Ready for Anything-Except This Strapped for cash, Souya signs up for a shady gig straight out of a video game: warp to a fantasy world with a team of experts and ascend a dungeon tower to make off with its spoils. However, an accident in the transfer process leaves him stranded there alone. Desperate for support, he recruits a host of adventurers-from elven sisters banished from their forest, to a Goddess of Deception and Secrecy partial to lazing about as a cat-to form a party that can brave the tower’s perils. Caught between corrupt nobles and merchants outside the dungeon and deadly monsters within, can this motley band rise to the challenge? Or will Souya’s adventure end before it even begins?
