DN: The Next Kira; Vol 2: Becoming Kira

After a long day at school, Marie finds the Death Note and takes it home with her before anyone else sees it. When she takes it home, Marie is convinced that she's taking home a regular book or a prank that some person made up to scare someone at the school. That is until she unintentionally uses the Death Note to kill a middle-aged man who kidnapped a little girl named Kanao Arata. After that, Marie discovers that the Death Note is real. She continues to use it on people who break the law and help innocent people. All is peaceful until she meets the very person she never thought she'd meet outside of her dreams.
