Synopsis: The Otherworlder, Exploring the Dungeon

Earth discovered the existence of other worlds in 1946. As predicted, many countries tried sending people to find resources and treasure on these new planets. Tragically, none of these explorers ever returned. Unexpectedly, Souya found himself accepting an offer from a dodgy company to travel to one of these worlds and earn enough money to save his younger sister. However, upon arrival, he realized that his journey would not be easy. Most of his essential supplies, including food and weapons, were destroyed during the transfer to this new world, and his team was missing. With only an AI companion to assist him, Souya must venture forth, trying to find something valuable enough to justify a rescue mission, provided anyone comes to his aid at all.
