An abnormal phenomenon called "Dark Hour" has been occurring at Jinguu Gakuen.
--People who are affected by the "Dark Hour" have their rationality knocked out of their grasp, and they are dominated by their carnal desires.
The explanation for this phenomenon was added: "If you try to resist this urge and continue to endure it, you will die.
Asada Shin could not believe these words for a moment.
However, he was soon confronted with the reality of the situation.
He reaffirms his role as "called upon to save those at the school".
As if to mock Asada, the situation was more serious than he thought.
One day, when he was relieved that he had not met the worst possible end due to the "dark hour," he was called back to the school to help save the school students.
He was headed for a town he had not been for a while because he lived in the school.
There, he saw a world where people without reason are spreading due to the underworld.
Why did the Meikoku have to spread outside of the school?
Asada was almost crushed by these questions, but the situation pushed him further.
The story of "Meikoku" finally comes to a conclusion at the end of a series of complicated intentions set in a women's school.
