History of Umientar: A Lecture by Professor Aryan Giandra

The world is in a threat of imbalance. Countless children and young people are murdered, all to obtain supremacy in the upcoming era. In the midst of this bloodshed, the only human town with no child victim suddenly welcomes foreign visitors. It is a mysterious town, one that has been closing off its gate from outsiders for many decades. However, the town doesn't welcome just anyone. Only those with an invitation are allowed to visit, and one of them is Aryan.

Burdened with moral duty as a historian, Aryan accepts a job offer to teach in a high school. Together with his assistant, he investigates the town not only to find a clue about the evil force behind the murder, but also to help save the world from the threat of war between two races.
