Son of Kira
Light Yagami had died because of a combination of bullet wounds and a heart attack at the hands of his shinigami Ryuk. He died on a staircase; not reaching heaven, nor falling to hell. He left behind three things. The first was his fan base. There were Kira supporters all around the globe. Once they heard the news that Light Yagami had died, crime rates skyrocketed and violence peaked. No one could kill the criminals now.
The second thing Light left behind was Misa Amane, his fiancé. Though you wouldn't have guessed it by his recent actions, Light really did love Misa. She completed him, despite her irrationality.
