When I woke up and was caught in a fire, the corpse slowly crawled up from under the bed. In panic, I picked up half of the bronze knife handle and accidentally killed the strange corpse.

Only this mysterious hilt is my only trump card for survival, and it is also the key to unraveling all the weird mysteries.
