Overlord, Vol. 18 (manga)

Now with the backing of the Baharuth Empire, Nazarick's forces have proclaimed themselves the rightful owners of the city E-Rantel. The Re-Estize Kingdom won't give up their territory so easily, however, and both sides prepare for a largescale war! Hoping to exploit Ainz's weakness, Prince Barbro leads his troops to the humble Carne Village—but what he finds there betrays all expectations… Can the Kingdom stand a chance against the force of nature that is Ainz Ooal Gown?!
