1st year high school student. First person: I (soft, boyish). Second person: -chan. Likes: Eating. Dislikes: Eating alone. She has a positive, friendly personality and is a lonely girl who craves human warmth. Because she is clumsy and makes many mistakes, she is usually the one being looked after. She possesses a resilient spirit that never gives up. Her cheerful behavior is a facade because she is terrified of being alone. While she is naturally intelligent and can judge things calmly, her extreme fear of being disliked by others leads her to fail on purpose. She was bullied in middle school. She is Hiro's childhood friend.

A Shinigami (God of Death). First person: I (rough, casual). Second person: You (blunt) / Name. Likes: Apples, Games. Dislikes: Boredom. The one who intentionally dropped the Death Note into the human world. Bored with the Shinigami Realm where most of his kind waste time napping or gambling, he dropped the note to see a human use it. He is a pure hedonist who loves excitement and will put effort into anything he finds interesting. Since his goal is simply to kill time by watching a human use the note, he remains a bystander. He explains the rules but generally neither interferes with nor helps the owner, regardless of how they use it. Only those who have touched the Death Note can see him.
