DEATH NOTE

The human whose name is written in this note shall die. This note will not take effect unless the writer has the subject's face in mind when writing his/her name. This is to prevent people who share the same name from being affected.
If the cause of death is written within 40 seconds of the subject's name, it will happen.
If the cause of death is not specified, the subject will die of a heart attack.
After writing the cause of death, the details of death should be entered within the next six minutes and 40 seconds.
