Cold Storage Locker No. 13

Lu Chen, a night-shift mortuary transport worker, receives a death certificate bearing his own name. In seven days, he will die at the hands of a vengeful ghost.

That same night, an unidentified female corpse is delivered to refrigerated locker number thirteen. Though the printer has no power, it spits out a receipt from the Register of the Dead all on its own.

Identify the deceased, record the truth of their death, and fulfill their final wish, and the underworld will grant you a talisman. Fail to file the case before the deadline, and the caseworker will be entered into the Register of the Dead in the deceased's place.

From then on, Lu Chen searches for the truth on behalf of the living by day, and seeks justice for the dead by night.

Until he discovers that the last deceased person registered with the seal his grandfather left him is none other than himself.
