My Gift Lvl 9999 Unlimited Gacha: Backstabbed in a Backwater Dungeon, I'm Out for Revenge!

Nemumu demands the guild promote Light to C-rank but is denied as Light was just recently promoted to D-rank. In order to raise their standing, Light takes on the quest to catch the adventurer killers, who target only humans. Suddenly, Light, Nemumu, and Gold feel a strange presence in the room. A battered Miya then falls from a portal that opens up in the ceiling. (Source: Muse Asia)
