Synopsis
■STORY
A school academy is being consumed by a yokai barrier.
The barrier grows stronger with each passing day.
Only 10 days remain before the barrier becomes complete——
At the same time, rumors spread throughout the academy of a mysterious entity called 【Tasogare-sama】.
Legend has it that if you encounter 【Tasogare-sama】 in the old school building after class, they will whisk you away while keeping you eternally young and beautiful……
Then, a transfer student arrives……
