Rules of the Death Note/Manga Chapter Rules

see also Fake Death Note Rules

The following is a list of all the rules for the Death Note and shinigami that have been revealed to the reader/viewer throughout Death Note, and in the thirteenth manga, How to Read. Some rules have been changed in How to Read, from what was mentioned in the manga. For instance, Sidoh states that for him to get his notebook back, he had to wait for the owner to die, or use up all of the pages, whereas in How to Read, it states that there are an unlimited amount of pages in the Death Note.

How to Use: XI

 * 1) Even after the individual’s name, the time of death, and death condition on the Death Note were filled out, the time and condition of death can be altered as many times as you want, as long as it is changed within 6 minutes and 40 seconds from the time it was filled in. But, of course, this is only possible before the victim dies.
 * 2) Whenever you want to change anything written on the Death Note within 6 minutes and 40 seconds after you wrote, you must first rule out the characters you want to erase with two straight lines.
 * 3) As you see above, the time and conditions of death can be changed, but once the victim’s name has been written, the individual’s death can never be avoided.

How to Use: XII

 * 1) If you lose the Death Note or have it stolen, you will lose its ownership unless you retrieve it within 490 days.
 * 2) If you have traded the eye power of a god of death, you will lose the eye power as well as the memory of the Death Note, once you lose its ownership. At the same time, the remaining half of your life will not be restored.

How to Use: XIII

 * 1) You may lend the Death Note to another person while maintaining its ownership. Subletting it to yet another person is possible, too. This also allows the person in current possession of the note to trade for the eyes of the Shinigami.
 * 2) The borrower of the Death Note will not be followed by a god of death. The God of Death always remains with the owner of the Death Note. (although the Shinigami is not obligated to.)

How to Use: XIV

 * 1) When the owner of the Death Note dies while the Note is being lent, its ownership will be transferred to the person who is holding it at that time.
 * 2) If the Death Note is stolen and the owner is killed by the thief, its ownership will automatically be transferred to the thief.

How to Use: XV

 * 1) When the same name is written on more than two Death Notes, the note which was first filled in will take effect, regardless of the time of death.
 * 2) If writing the same name on more than two Death Notes is completed within 0.06 seconds, it is regarded as simultaneous; the Death Note will not take effect and the individual written will not die.

How to Use: XVI

 * 1) The God of Death must at least own one Death Note. That Death Note must never be lent to or written on by a human.
 * 2) Exchanging and writing on the Death Note between the gods of death is no problem.

How to Use: XVII

 * 1) If the God of Death decides to use the Death Note to kill the assassin of an individual he favors, the individuals life will be extended, but the God of Death will die.
 * 2) The dead God of Death will disappear, but the Death Note will remain. The ownership of this Death Note is usually carried over to the next god of death that touches it, or is kept in possession of the human owner of the Death Note.

How to Use: XVIII

 * 1) Only by touching each other’s Death Note can human individuals who own the Death Note in the human world recognize the appearance or voice of each other’s God of Death.
 * 2) An individual with the eye power of a god of death can tell the name and life span of other humans by looking at that person’s face. By possessing the Death Note, an individual gains the ability to kill, and stops being a victim. From this point, a person with the Death Note cannot see the life span of other Death Note owners, but they will not be able to see his/her own life span.
 * 3) The God of Death must not tell humans the names or life spans of individuals he/she sees. This is to avoid confusion in the human world.

How to Use: XIX

 * 1) It is prerequisite for the Death Note used in the human world that a living god of death makes sure that the humans in the human world uses it.

How to Use: XX

 * 1) In order to see the names and life spans of humans by using the eye power of the god of death, the owner must look at more than half of that person’s face. When looking from top to bottom, he must look at least from the head to the nose. If he looks at only the eyes and under, he will not be able to see the person’s name and life span. Also, even though some parts of the face, for example the eyes, nose or mouth are hidden, if he can basically see the whole face, he will be able to see the person’s name and life span. It is still not clear how much exposure is needed to tell a person's name and life span, as this needs to be verified.
 * 2) If the above conditions are met, names and life spans can be seen through photos and pictures, no matter how old they are. But this is sometimes influenced by the vividness and size. Also, names and life spans cannot be seen by face drawings, however realistic they may be.

How to Use: XXIII

 * 1) When an individual with ownership of more than two Death Notes loses possession to one of the Death Notes, he will not be able to recognize that Death Note’s god of death’s appearance or voice anymore. The god of death himself will leave, but all the memory involving that Death Note will remain as long as he maintains ownership of at least one other Death Note.

 * 2) If you write, “die of disease” for the cause of death, but only write a specific time of death without the actual name of disease, the human will die from an adequate disease. But the Death Note can only operate within 23 days (in the human calendar). This is called the 23-day rule.

How to Use: XXVIII

 * 1) If you write, “die of disease” like before with a specific disease’s name, but without a specific time, if it takes more than 24 days for the human to die the 23-day rule will not take effect and the human will die at an adequate time depending on the disease.

How to Use: XLVII

 * 1) The god of death will not die from lack of sleep. Moreover, gods of death do not really need sleep. The meaning of sleep for gods of death is essentially different from humans and is merely laziness.

How to Use: XLIII

 * 1) Only 6 Death Notes are allowed to exist at a time in the human world. Of course, the Death Note that the god of death owns does not count. This means only 6 gods of death that have passed on their Death Note to humans can stay in the human world.

How to Use: LIII

 * 1) In order to make the Death Note take effect, the victim's name must be written on the same page, but the cause of death and situation around the death can be described in other pages of Death Note. This will work as long as the person that writes in the Death Note keeps the specific victims name in mind when writing the cause and situation of death.

How to Use: LIV

How to Use: LIX

How to Use: LX

 * 1) Even if a new victim’s name, cause of death, or situation of death is written on top of the originally written name, cause of death or situation of death, there will be no effect on the original victim’s death.

How to Use: LXI

 * 3) If the victim’s name and cause of death have been written and the middle of writing the situation of death, then the victim will be killed within 6 minutes and 40 seconds via the stated cause of death if the cause is possible within that period of time, but otherwise, the victim will die by heart attack.

How to Use: LXII

 * 1) No matter what medical or scientific method may be employed, it is impossible for humans to distinguish whether or not the human has the eye of power of a god of death. Even gods of death cannot distinguish this fact, except for the very god of death that traded his/her eye power with that human.

How to Use: LXIII

 * 1) The following situations are the cases where a god of death that has brought the Death Note into the human world is allowed to return to the world of gods of death:

END
All humans, without exception, will eventually die.

After they die, the place they go to is MU (nothingness).

Once dead, they can never come back to life.
