アルムバタフライ　～星々のデュエル～

Hundreds of years in the future—a calamity has wiped out most of the female population, and the remaining women have been isolated on the Moon. Now, Earth is inhabited solely by men… Only the most exceptional among them are allowed to travel to the Moon and pass on their genes. The protagonist, Liang, enrolls in “Arktos,” a university that serves as the gateway to the Moon. However, Liang’s reason for enrolling isn’t to reach the Moon, but to investigate a certain “incident.” What seemed like a simple case soon becomes complicated. The reason lies in the disturbing practices happening within Arktos… To select the elite males, students are forced to battle one another. Liang, too, is thrown into this brutal competition. Will he be able to uncover the truth behind the incident…?
