Overlord IV

E-Rantel, the capital city of the newly established Sorcerer Kingdom, is suffering from a severe shortage of goods. Once a thriving trade hub, it now faces a crisis due to its fear of its king, Ainz Ooal Gown. To address this, Ainz sends Albedo to the city as a diplomatic envoy. Meanwhile, the cardinals of the Slane Theocracy are discussing how to retaliate against Ainz after his attack crippled the Re-Estize Kingdom's army. It is their plan for the Baharuth Empire to take over the Sorcerer Kingdom.

But when Emperor Jircniv Rune Farlord El Nix arranges a meeting with the Theocracy's messengers at a colosseum, he is met with Ainz himself. With the secret gathering now exposed, the emperor and his guests learn that Ainz has challenged the Warrior King, the empire's greatest fighter, to a duel. Ainz's intentions are beyond comprehension, leaving Jircniv to watch as humanity's future changes before his very eyes.
