Katsumi Nakamurai was the daughter of a well known detective whom had now passed away. She was well known by local police and detectives alike, and seemed to be mostly kind towards everyone. Then, while waiting for a bus late at night, she found something. A notebook, labeled "death note". She presumed it was phoney at first, but after a few small 'test runs' she quickly realised that this said death note did, in fact, work. She held the ability to kill whomever she pleased.
