Who Dares to Keep Someone Until the Fifth Watch?

When I wake up, horrific events appear one after another. These horrific events seem to be regular and irregular, but the number of people dying is increasing. Some horrific events have been passed down through history and no one has been able to solve them. Some events seem to not exist in this world but were spread from other worlds. In short, if the Lord of Hell wants you to die at the third watch, who dares to leave people until the fifth watch. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
