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

Light is banished from the Concord of the Tribes, leading to a swift betrayal by his former comrades. He narrowly escapes their treachery by fleeing to the Abyss, the most treacherous dungeon in the realm. There, he uses the Unlimited Gacha to summon Mei, a skilled Level 9999 fighter, and eventually builds his own kingdom. Three years later, Light has amassed significant power and now seeks revenge against those who wronged him, starting with his former allies.
