Episode One is basically the introduction of Death Note and Raito Yagami. Raito is a genius stuck in school, and Ryuk is a Shinigami (Death God) with immortality, but nothing to do. They both believe in one thing though, the world is rotten. For some fun, Ryuk drops his Death Note, which has the power to instantly kill people, into the human world...
In this episode, Raito is as busy as ever. If he’s not at school, doing homework or sleeping, he’s passing judgement upon criminals. When Sayu, Raito’s sister, asks for help with homework while he was writing names in the Death Note, Ryuk mentions that if anyone touches the Death Note, they will instantly see Ryuk. Raito had to find a way to hide it...
