Based on the erotic game by ZION.

Clarice, the only princess in the elven kingdom of Eld, is also a shrine maiden who can predict the future through prophetic dreams, a tradition passed down through generations. But one day, she has an ominous dream in which the entire kingdom is swallowed up in darkness. She hurries to meet with her parents, the king and queen, who highly respect Clarice's abilities and believes that the country is in danger. However, he is puzzled by Clarice's theory that it is the Orc King's mass breeding campaign, a phenomenon that has been going on since the world's founding. And that night, Clarice's fears become reality, and an unprecedented threat approaches. A horde of orcs swarms the castle while the Royal Guard, led by Leona, a beautiful half-elf and Clarice's childhood friend, is away. Leona rushes to the castle after hearing the news and rescues Clarice just in time, but the Orc King, targeting her superior female body, pursues her relentlessly. After that, Clarice and her friends managed to escape to a neighboring country, even though many of their soldiers and attendants were killed by the orcs. However, that land was not safe either, and their pure bodies were violated...!!
