Jin Harker has one skill: surviving dungeons where everyone else dies.

He didn't plan it that way. He's not a killer. He's just a failed D-rank adventurer who hides better than he fights. And apparently, that's enough to walk away from disasters that bury the rest of his party.

Then he finds the receipt.

Glowing blue, visible only to him, it appears after every dungeon massacre he survives: Deaths Processed: 5. Points Awarded: 500. Thank you for your patronage.

The universe has a shop. And Jin is its best customer. It sells him better gear, better skills, better odds of surviving the next disaster.
