Kotokunibito Dungeon ni Moguru

In 1946, humanity discovered the existence of alternate dimensions. Naturally, nations rushed to send expeditions into these unknown realms, eager to claim rare resources or legendary artifacts. None returned. Souya never imagined he’d become one of those explorers, yet desperate circumstances forced his hand. With his sister’s life hanging in the balance, he accepted a dubious offer from a shadowy corporation. Thrust into a foreign world, he quickly realized survival wouldn’t be easy—his companions had vanished, and most of his supplies were lost during the unstable dimensional crossing. Now, alone and unprepared, Souya must navigate a treacherous dungeon filled with unknown dangers. His only motivation? The hope of returning home with enough wealth to change their fate. But the deeper he ventures, the more he questions whether escape is even possible. The dungeon holds secrets far deadlier than he anticipated, and every step forward could be his last.
