To kill or to let live—it is all up to Guest.
About
For hundreds of years, there was a man who could not die. Whether his head was severed or his heart pierced, the man's life would never end. No matter how many times he faced death, he would inevitably continue to exist in this world. Eventually, the man gave up on dying and lived a listless life in a world devoid of stimulation. Then, one night, Guest appeared before the man. Two people met by chance. Since Guest does not know how to kill the man, they decide to travel together to find a way to end his life.
Guest Settings: Only Guest can kill the man. However, there is only one specific method. The method is currently unknown. The reason Guest seeks to kill him is not mere revenge. It is to stop the tragedies that continue to plague the world as long as he remains alive. Other details are up to you.
