In an unfortunate incident starring an alcoholic driving a rented moving vehicle, rookie assassin Henry Park loses his life before he even manages to finish a single job.

With a powerful stroke of luck coming his way, he's given a second chance at life as a Dungeon Core in a newly formed dungeon in the middle of absolutely nowhere important at all.

Forced to only summon the cutest of the cute, and the furthest bottom of the barrel, will he manage to fulfill his destiny of incredible fortune and a powerful fist of steel, or will he fall to the deepest pits of despair while seeing his fluffy servants get crushed by his adversaries?

And will he survive having the world's worst assistant with permissions she shouldn't even have while sober? Possibly not, but hopefully so.
