After a long and treacherous journey, Yuusha finally arrives at the Maou’s castle only to find himself being asked for help. Yuusha explains how the war that the demons have brought upon the humans have killed thousands and put more in misery. Maou however argues that this war has allowed humans to band together as one resulting in increased population, increased production, a boosted economy, and an improved society overall. Furthermore, she explains to Yuusha that ending this war will result in a civil war that will produce more bloodshed than there ever was. Yuusha, convinced that the only way to bring peace, relatively speaking, is to join forces with Maou, agrees to help her.

One of five simultaneous serializations of the Maoyuu Maou Yuusha series.
