Friend

Friend (友人, Yūjin) is the fourteenth episode of the Death Note anime series.

Synopsis
After Light introduces Misa Amane to his Shinigami, Ryuk, the two discuss their plans to get rid of L. Their plan is to confuse him about Kira's powers and send him towards a different path, other than the one leading towards Light. Taking advantage of the situation, and of Misa Amane's love and affection for him, Light concludes that he can use her to throw off L, whilst his plans for a better world can be fully completed. However, Misa's Shinigami - Rem - threatens him if her safety is compromised in any way, she will write down his name in her own Death Note. In the meantime L is thrown off the trail by the second Kira and is left confused about the new audio tapes purposely denouncing the police's actions for making the first Kira appear as a pariah. L concludes that the two Kiras might have met and are working towards the same goal.

Rules Learned

 * How to Use: X #1 - “Suicide” is a valid cause of death. Basically, all humans are thought to possess the possibility to commit suicide. It is, therefore, not something “unbelievable to think of".
 * How to Use: X #2 - Whether the cause of the individual’s death is either a suicide or accident, If the death leads to the death of more than the intended, the person will simply die of a heart attack. This is to ensure that other lives are not influenced.
