Night Shift Incident

Kizuna Tsurugi (Minami Kotona) is a convenience store night-shift worker, clocking in as usual, everything seems calm. But when someone says, 'I received this 4 days ago,' the atmosphere in the store instantly turns sour, and a sense of eeriness sweeps in. After that, a mysterious SD card arrives every day, followed by one strange occurrence after another in the convenience store, each more spine-chilling than the last.
