Rules of Death note

Ryuk writes instructions in English inside his Death Note with the belief that English is the most popular language in the human world.

* The human whose name is written in this note shall die.
* 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 affected.
* If the cause of death is written within 40 seconds of writing the person's name, it will happen. If the cause of death is not specified, the subject will simply die of a heart attack.
* After writing the cause of death, the details of the death should be written in the next 6 minutes and 40 seconds.

Fake rules

These rules were written in the Death Note to aid Light in a scheme he came up with to clear his and Misa's names. They were written by Ryuk but are completely false.

* If the owner of a Death Note does not use the notebook after 13 days time, he/she will die.
* If the Death Note is damaged or burned, any people who have touched the Death Note will die.
