Summoned to another world and forced to fight a war, Alex didn't even survive the first day, dying at the hands of a grotesque monster. But things weren't over for him when he found himself reborn as an imp in a dungeon.

Having experienced death once, Alex swore to never let himself killed again. However, in an environment where even the beings of the same species were your potential enemies, can such a thing be possible? Thankfully, Alex still had access to the system he gained as a transmigration bonus when he was summoned to this world. With it, maybe it was possible for him to survive the hellish prison called dungeon and one day have his revenge against the empire that summoned him.

All in the future though, but first, he had to survive the terror of goblins that loomed over his head...
