In my second year of university, I received a letter from the girl who was my first love.
Aki Sakura, the girl who inspired me when I was a child.

The protagonist, Konno Jun, arranges to meet her once more for the first time in ten years.
However... The Sakura who appeared before him was all too different from the girl he used to know.

"Will you save me?"

Within seconds, Jun is transported to a strange world.
A coin parking at night.
Just about as Sakura was being assaulted and raped...
