Death Note › Season 1

Chapter 24 — Revival

Higuchi is arrested on grounds of being Kira and causing multiple murders in the region of Kanto. Inspecting Higuchi's Death Note, L discovers that shinigami do exist. While L is stunned, Light takes the Death Note from him and remembers that he is the original Kira. Light then kills Higuchi by writing his name on a scrap of the Death Note. It is revealed that when Light gave away his Death Note, he added a fake rule stating that, after having written in the book, its owner must continue to use it at least once every thirteen days or perish. The investigation team reviews the rules written in the book and finds that they can do little to get rid of it. Meanwhile, Light orders Misa to recover the other Death Note he had hidden a few months earlier. Misa makes a second deal with Ryuk for the shinigami eyes in order to find out L's true identity. (Source: Wikipedia)
