Maoyuu Maou Yuusha: 'Kono Watashi no Mono Tonare, Yuusha yo' 'Kotowaru!'

A Hero arrives at the Dark Lady's castle after a perilous journey, only to be asked for assistance. He recounts the devastation caused by the demon-led war, which has killed many and caused widespread suffering. The demon queen counters by stating that the conflict has unified humanity, providing data showing population growth, increased productivity, economic gains, and societal improvement. She warns that ending the war would lead to civil strife with even greater bloodshed. Convinced that peace, however fragile, can only be achieved by cooperating with her, the Hero agrees to support her plans.
