How to Build a Dungeon: Book of the Demon King manga volume 5 features story by Yakan Warau and art by Toshimasa Komiya.

A single foe stands between Aur and victory: Wolf, the Hero King. With his children dead, the king at last takes the field himself. Faced with that dreadful opponent, Aur prepares an equally terrifying strategy. Can the Hero hope to slay one of the world’s last remaining dragons? The earth trembles as living legends battle…and the night grows heated, as Aur tests the passion of his captives.
