Overlord IV - Episode 13 [END] - Ainz's Forces in Throne Room

Climb, the only human left running around the palace, found Ainz sitting on the throne. Where was Renner?

Mare, a boy that wears a skirt, psyched himself up before burning the capital city to the ground. His forces helped! He also ensured Climb didn't get caught up in the carnage as the knight performed an errand for Renner.

After Ainz killed Climb in front of Princess Renner, he woke up in a strange bed. Ainz had resurrected him and turned Renner into a demon! It was her reward for delivering the fall and destruction of her kingdom! Her extra reward was Climb's life if he accepted becoming a demon too. Renner's evil smile in past seasons was all the foreshadowing we needed.

Albedo enjoyed killing the disgusting diplomat she tolerated. On a throne made of rubble, Ainz celebrated his outlandish demonstration to the rest of the world of the consequence of crossing the Sorcerer Kingdom.
