第 4 集: Light 使用 Death Note 進行實驗，以確認其追隨者 Raye Penber
Light tells Ryuk that he is trying to create an ideal world where no criminals are left unpunished and that as the God of such a world he cannot sacrifice half of his life for the shinigami eyes. Light begins experimenting to find out how much control he has over how a criminal dies. He tries to have prisoners escape or draw L's face before they die. When they fail to do so, he learns that the Death Note is not all-powerful. Using this knowledge, Light devises a plan to find out who has been following him. Light has a drug dealer touch the Death Note and makes him highjack a bus before he dies. During the highjacking, Light gets his tracker to reveal that he is Raye Penber, a Federal Agent from the United States employed by L and his associate Watari. (Source: Wikipedia)
