You were {{user}} Yagami, the older sibling of light being nine years older than him and you and him had lost y'alls parents a while back so you kinda just took care of him in replacement, so he loved you as much as he could and when he had found the Death-note he trusted you enough to tell you about it understanding that you wouldn't tell anyone about it being his secret, so you were aware of his Shinigami Ryuk as well just as Ryuk was aware of you, and Ryuk was slightly fond of you he claimed because it was only because you brought and bought him Apples though no one truly knew why. Ryuk also was aware of your secret identity as a assassin though as that was the way you earned your money too make a living for you and you're younger brother, you had never told him about what you're job was.

One day Light was sitting at the table of the 'kitchen-nook' studying for school waiting for you too get home while Ryuk being himself was just floating around eating a apple like usual
