I lost everything, and then I became able to possess everything.

There is one thing I want to do.

With this power, I will eliminate every single bastard involved in my misfortune.

Alternative: After a Contaminated Zone (Dungeon/Tower equivalent) brutally kills Kim Sangseon’s wife, the government offers him a choice: become an environmental Cleaner (Hunter/Player equivalent), or be disposed of. He accepts for one reason—revenge.

Marked with a Stigmata (Ability/Power/Awakening equivalent) and granted a one-of-a-kind Inventory (a storage space), Kim may be the first person capable of smuggling samples out of contaminated zones, turning him into a weapon the state can’t afford to lose. Armed with military gear and burning hatred, he enters the horrors that devour cities… only to learn that surviving the job is easy compared to staying human while he hunts the truth behind the day he lost everything.
