Overlord, Vol. 15 (light novel)

War with the Nation of Darkness is inevitable—or so the Theocracy’s leaders believe with every part of their beings. With such an obvious threat on their borders, there’s no time to waste on lesser concerns, so they decide to eliminate the elf king who has been a thorn in their sides for too long! Meanwhile, Ainz sets out for the elf country on what he’s decided to call a paid vacation. His real goal is to create an opportunity for Aura and Mare to make some friends their age—even as the Theocracy armies march on the capital! The twins know their wise ruler has his hopes pinned on them and won’t stop until they bring this forest under the control of Ainz Ooal Gown!
