"Subaru's first day at the Roswaal mansion begins for the third time. The first time, he grew weak and died of unknown reasons in his sleep, and the second time, he was killed by an attacker. The sound of chains that he heard as he died the second time replays in his mind, waking him in a terrified, cold sweat. He has no idea what the killer is after, let alone who it is, so he makes a plan to leave the mansion on the fourth night and watch for the attack to happen.

Standing before Subaru is someone he never expected. The truth of the attacker's identity leaves him bewildered, and he feels everything crumbling around him as he dies yet again. Then, for the fourth time, he awakes on his first day at the Roswaal mansion. This time, the night of the fourth day passes without incident, and Subaru is stunned as he greets the morning of the fifth day... but then the situation takes an unexpected turn."
