Synopsis: Onna Kishi, Keiri ni Naru.

120 years ago, the people of the "Human Nation" discovered a new continent and began colonizing it with a large fleet of ships. The new land brought abundant harvests, and hunger and poverty seemed to be a thing of the past. However... to the west of the settlements, beyond the mountain range, the demons were living and developing their own culture and society. The humans named the area inhabited by the demons the "Demon Country" and dispatched an army to defeat them. Thus began a war of over 100 years between the human and demon nations. In the midst of this war, a female knight makes a mistake in the Demon Kingdom and is captured by orcs. What were the orcs' unexpected words to her? A heroic fantasy tale of accounting!
