Encounter

Encounter (遭遇, Sōgū suru) is the ninth episode of the Death Note anime series.

Synopsis
L's suspicions are momentarily subdued, although he still hints that Light Yagami may in fact be Kira. At the college entrance exams Light notices a mysterious and eccentric person staring at him. It is L pretending to be a student and who is sitting and observing Light's actions. L has now taken on the name Hideki Ryuga, the same name as a famous idol. Light is then shocked at the fact that L introduces himself using this name and his own very discreetly. It would be too suspicious for L to die after meeting Light, so he decides to befriend L and plan his death at a later time. After panicking and feeling humiliated when he gets home, Light decides this is the best course of action to take for now because getting closer to L means he could gather more information into his true identity and keep a closer eye on the police.

Rules Learned

 * How to Use: V #4: A god of death cannot be killed even if stabbed in his heart with a knife or shot in the head with a gun. However, there are ways to kill a Shinigami, which are not generally known to the Shinigami.
 * How to Use: VI #1: The conditions for death will not be realized unless it is physically possible for that human or it is reasonably assumed to be carried out by that human.
