Light Yagami
Ohba claims that the series ended more or less in the manner that he intended for it to end; he considered the idea of L defeating Light Yagami with Light dying, but instead chose to use the "Yellow Box Warehouse" ending. According to Ohba, the details had been set "from the beginning". The writer wanted an ongoing plot line instead of an episodic series because "Death Note" was serialized and its focus was intended to be on a cast with a series of events triggered by the Death Note. "13: How to Read" states that the humorous aspects of "Death Note" originated from Ohba's "enjoyment of humorous stories".
