Meanwhile, in the real world, a series of girl disappearances occur, and

Sakaki, sensing the involvement of a supernatural entity, secretly begins an investigation.

After a fierce battle with a mysterious villain, Reimu returns to the real world.

However, the girls are taken hostage, and she is captured and

subjected to a brutal physical examination, her body violated from her womb to her anus.
