Resurrection from the Dead? This Body Defies Science!

He died in a mental hospital and his soul returned to the abyss of consciousness. When a body that had been medically declared dead stood up again, there were several completely different souls entrenched in it. Sharing memories, sharing hatred, and going for a life-and-death revenge together. The killer controls the body, the doctor analyzes the paradox, and all the personalities are united—— If you owe me, I will repay you a hundred times; if you harm me, I will let you fall into hell. This body that has died once will fight its way out of the darkness!
