Great Eastern Death Note 8" Ryuk Plush
Ryuk is a Shinigami who indirectly gives Light Yagami a Death Note. Ryuk was bored with the activities (or lack thereof) of the Shinigami Realm, and decided to obtain a second Death Note and dropping it in the Human World for someone to find, hoping to amuse himself from the boredom he had endured. This Death Note is found by Light, leading to his attempt to rid the world of evil, and easing Ryuk's boredom.
