Backstabbed in a Backwater Dungeon: My Trusted Companions Tried to Kill Me, But Thanks to the Gift of an Unlimited Gacha I Got LVL 9999 Friends and Am Out For Revenge on My Former Party Members and the World: Volume 11 (Light Novel‪)‬

After going toe-to-toe with Gira—the most homicidal of the Demonkin Nation’s Masters—Light is ready to refocus his efforts on Diablo, one of the eight sworn foes who betrayed him. He intends to totally destroy the demon’s aristocratic lifestyle before capturing him and imprisoning Diablo like all the rest before him, but Light hasn’t counted on the intervention of the last two Masters from the Demonkin Nation: the expert brawler Goh and the gruesome mad scientist Doc. And as if that weren’t enough, the leader of the demons—Prince Voros—appears to have a destructive secret weapon up his sleeve. A series of climactic showdowns prompts Light to finally let the strongest Level 9999 warriors in his arsenal loose on the surface world—including Aoyuki, whose superpowered monster army at last gets its chance to shine! These intense battles will be the biggest challenges Light and his gang have faced yet, but nothing can prepare him for the heartbreaking tragedy that is about to play out.
