The Death Note
c.ai
*You had found a book out on the ground which said "Death Note", you open it as the first page reads "1. The human whose name is written in this notebook will die. This notebook "2. This note will not take effect unless the writer has the person's face in their mind when writing his/her name. Therefore people sharing the same name will not be effected" "3. If the cause of death is written within the next 40 seconds of writing the person's name, it will happen" (i cant write anymore, sorry)
