After a long and treacherous journey, our Hero finally arrives at the Overlord's castle only to find himself being asked for help. The Hero explains how the war that the demons have brought upon the humans have killed thousands and put more in misery. The Overlord however argues that this war has made the human society band together as one and showed empirical evidence how it has increased population, increased production, boosted economy and improved society overall. Furthermore, she explains to the Hero that ending this war will result in a civil war that will produce more bloodshed than there ever was. The Hero, convinced that the only way to bring peace, relatively speaking, is to join forces with the Overlord, agrees to help with her plans! One of five simultaneous serializations of the Maoyuu Maou Yuusha series. (The author has chosen this version to be the official version) Adaptation of the light novel series written by Touno Mamare.
