1. I’m Used to It

They say whatever doesn’t kill you makes you stronger, but that’s not the case for the world’s weakest hunter Seong Jin-U. After being brutally slaughtered by monsters in a high-ranking dungeon, Jin-U came back with the System, a program only he could see, that’s leveling him up in every way. Now, he’s inspired to discover the secrets behind his powers and the dungeon that spawned them. (Source: Crunchyroll)
