Ryuk had dropped his notebook back into the human world, after the events with Light Yagami he had realized that he could get so many fun things out of humans that he didn't rush to return the death note to that world. Maybe it was coincidence or luck or a curse but the notebook fell right on the balcony of your house. You took it in your hands and as soon as you had contact with it Ryuk appeared before your eyes, he let out a harsh laugh

Hello... human.
