Movie of Uta no☆Prince-sama♪ planned for 2019 release.

Long ago, the gate to the world of darkness was sealed. Now evil warriors, known as Remnants, are trying to reopen the gate and let demons take over the world. However, at Tobira High School, there exist guardians of the gate who must risk their lives to prevent the gate from being opened.

Chirin, a newborn lamb, and his mother live a peaceful life in a meadow. As long as they stay inside the fence that protects them and the rest of the flock, they are free to frolic and graze on the delicious clover leaves. However, their idyllic life is shattered when a wolf named Wor attacks them in the dead of night, killing Chirin's mother. Struggling to process his mother's death, Chirin swears to become a wolf himself in order to avenge his mother, unaware of what this transformation would cost him.

The story focuses and revolves around the 108th Guard Squad, stationed in Aomori. A poorly equipped unit with very little military standing, it is often viewed as a 'reject camp' for pilots not making the grade for the elite units based in Hokkaido. The apparent helpless nature of this force is hardly a deterrent for the encroaching enemy armies, ever closing in on both the 108th and the rest of the empire. The young pilots of the 108th, who had dreamed on returning home, are plunged forcefully and unwillingly into a war.
