Rules of the Death Note/How to Read Rules

This article lists the rules compiled in Death Note 13: How to Read.

The Japanese version of each rule is the same as the original Japanese used for the manga chapter rules, but Viz made some translation errors in their English release. Errors should be noted in Rules of the Death Note/Manga Chapter Rules.

1.5 Other Things to Consider
The human who uses this note can go neither to Heaven nor to Hell.

One page taken from the Death Note, or even a fragment of the page, possesses the full power of the note.

Any writing instrument or medium (cosmetics, blood, etc.) may be used, as long as it can write directly onto the note and create legible text.

The pages of the Death Note will never run out.

Some limited number of Death Notes have white or red front covers, but this makes no difference in their effectiveness as compared with the black Death Notes.

II. Ownership
This note shall become the property of the human world once it touches ground in the human world.

The owner of a Death Note can recognize the image and voice of the original owner - a Shinigami, for example.

The human who touches the Death Note can recognize the image and voice of its Shinigami owner, even if the human is not the owner of the note.

Whenever a Shinigami in the human world dies and leaves behind its Death Note, the note's finder automatically becomes the owner. However, in this case, only a human who can see and hear that Shinigami is able to see and touch the Death Note. It is very unlikely, but if by any chance another Shinigami picks up the Death Note, that Shinigami becomes the owner.

2.2 Situations Surrounding Ownership
If you lose the Death Note or have it stolen, you will lose its ownership unless you can retrieve it within 490 days.

When the owner of the Death Note dies while the note is on loan, its ownership will be transferred to the person who is holding it at that time. If the Death Note is stolen and the owner is killed by the thief, its ownership will automatically be transferred to the thief.

The individuals who lose ownership of a Death Note will also lose their memories of it. However, this does not mean that they will lose all memories from the period of ownership: they will only lose the memories involving the Death Note.

When an individual with ownership of more than two Death Notes loses possession of one of them, he will no longer be able to recognize or hear that Death Note's Shinigami anymore. The Shinigami will leave, but all the memories involving the Death Note will remain to the owner as long as he maintains ownership of at least one other Death Note.

If a person loses possession of a Death Note he will not recognize its Shinigami by sight or voice anymore. However, if the owner lets someone else touch that Death Note, from that time on that person will continue to recognize the Shinigami's appearance and voice until he or she actually becomes the owner of the Death Note and subsequently loses possession of it.

When regaining ownership of a Death Note, the memories associated with it will also return. In cases where the owner was involved with other Death Notes as well, memories of all the Death Notes involved will return. The memories will return just by touching the Death Note, even without obtaining ownership of it.

Memories related to a Death Note are lost when its ownership is lost. But they may be regained by either obtaining ownership once again or by touching the Death Note. This can be done up to six times per Death Note. Any times more than that, the person's memory of the Death Note will not return and they will have to use it without any previous memory of it.

Even if you do not actually possess the Death Note, you may still use it to full effect.

You may lend the Death Note to another person while maintaining its ownership. The borrower may lend it to yet another person as well.

The person who borrows the Death Note will not be followed by a Shinigami. The Shinigami always remains with the owner of the Death Note. Also, the borrower cannot trade for the Shinigami Eyes.

Only by touching each other's Death Notes can owners recognize the appearance or voice of each other's Shinigami.

Losing memory of the Death Note by passing the ownership to another or by abandoning ownership will only occur when someone is actually killed using that Death Note. You will not lose memory of the Death Note if, for example, you merely owned it and did not write down anyone's name. In this case, you will not be able to hear or see the Shinigami anymore. You will also lose the power of the Shinigami Eyes if you made the trade.

2.3 Multiple Notebooks
Someone possessing more than one Death Note may write down a victim's name in one of the Death Notes and the cause of death in the other, and the death will still occur. The order of writing, however, is unimportant: if you write down the cause of death in one Death Note and afterward write the name in the other, the death will occur. This can be accomplished by two Death Note owners working together. In this case, it's necessary that the two touch each other's Death Notes.

Only six Death Notes are allowed to exist at a time in the human world. Of course, the Death Notes that the Shinigami own do not count. This means only six Shinigami that have passed on their Death Notes to humans can be in the human world at once.

One Shinigami is allowed to pass on Death Notes to only three humans at a time. However, it is possible for a single Shinigami to hand out up to six Death Notes - by handing three humans two Death Notes each, for example. In other words, one human could potentially own all six Death Notes.

If a seventh Death Note is given to a human when six already exist in the human world, nothing will happen when it is used.

In the event that there are more than six Death Notes in the human world, only the first six Death Notes that have been delivered to humans will have effect. The seventh Death Note will not become active until one of the other six Death Notes is destroyed or a Shinigami takes one of them back to the Shinigami realm.

III. The Shinigami Eyes
A human who becomes the owner of a Death Note can, in exchange for half of his or her remaining life, acquire the power of the Shinigami Eyes, which will enable him or her to see a human's name and remaining life span when looking at them.

If you have traded for the Shinigami Eyes, you will lose that power as well as the memories of the Death Note once you lose ownership of the note. Moreover, the half of your life you traded away will not be restored.

An individual with Shinigami Eyes can see the name and lifespan of another human by looking at that person's face. By gaining ownership of a Death Note, an individual not only gains the ability to kill but also stops being a victim. From this point on, a person with a Death Note cannot see the life span of other Death Note owners, including him or herself.

In order to see the names and life spans of humans using the power of the Shinigami Eyes, the owner must be able to see more than half of that person's face. When looking from top to bottom, he must be able to see 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 lifespan. 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 lifespan.

It is still not clear how much exposure is needed to see a name and life span (more research needs to be done). If the above conditions are met, names and life spans can be seen using photos and digital images, no matter how old they are. But this is sometimes affected by the resolution and size of the image. Also, names and life spans cannot be seen using drawings, however realistic they may be.

Those with Shinigami Eyes will have eyesight of over 3.6 in the human measurement, regardless of their original eyesight.

If you have traded for the Shinigami Eyes, you will see a person's primary life span in the human world.

The names you will see with the Shinigami Eyes are the names needed to kill that person. You will be able to see a name even if it isn't officially registered anywhere.

Humans who have traded for Shinigami Eyes cannot see the names or life spans of humans who have already passed away (by looking at photos of them, for example).

The use of the Death Note in the human world sometimes affects other humans' lives or shortens their original life spans, even if their names are not actually written in the notebook itself. In these cases, no matter the cause, the Shinigami sees only the original lifespan and not the shortened lifespan.

No matter what medical or scientific method is employed, it is impossible for humans to distinguish whether or not a human has Shinigami Eyes. Even Shinigami cannot distinguish this fact, except for the very Shinigami that traded his or her eye power with that human.

4.1 Relationship with the Owner
The human owner of a Death Note is possessed by its original Shinigami owner until he or she dies.

If a human uses a Death Note, its Shinigami owner must appear in front of the human within 39 days after he or she uses the note.

The original Shinigami owners of Death Notes don't, in principle, do anything to help or prevent the deaths brought about by the notes.

A Shinigami has no obligation to completely explain how to use the note or the rules that apply to the human who owns it.

The Shinigami must not tell humans the names or life spans of individuals he sees. This is to avoid confusion in the human world.

A Shinigami bringing a Death Note into the human world must make sure that a human uses it. Although it is unlikely that a Shinigami who has possessed a human would die, if it does happen, the Death Note brought into the human world will not lose its power.

Shinigami must not stay in the human world without a particular reason. Acceptable reasons to stay in the human world are as follows:

I. When the Shinigami's Death Note is handed to a human.

II. Finding a human to take possession of a Death Note should be done from the Shinigami realm, but if it is within 82 hours this may also be done in the human world.

III. When a Shinigami stalks an individual with an intention to kill them, as long as it is within 82 hours of possessing them the Shinigami may stay in the human world.

The Shinigami must not hand the Death Note directly to a child under six years of age (based on the human calendar). But Death Notes that have been dropped into the human world, and are part of the human world, can be used upon humans of almost any age with the same effect.

The owner of a Death Note cannot be killed by a Shinigami who is in the Shinigami realm. Also, a Shinigami who comes to the human world with the objective of killing the owner of a Death Note will not be able to do so. Only a Shinigami that has passed on its Death Note to a human is able to kill the owner of the Death Note.

If a Death Note is owned in the human world against a Shinigami's will, that Shinigami is permitted to stay in the human world in order to retrieve it. In that case, if there are other Death Notes in the human world, the Shinigami are not allowed to reveal to the humans the Death Note owner's identity or its location.

If a Shinigami's Death Note is taken away for whatever reason, it can only be retrieved from the Shinigami who possesses it at the time. If there is no Shinigami, but a human, the only way the Shinigami can get it back is to first touch the Death Note and become the one who haunts that particular human. Then they have to wait until that person dies to take it away. And they have to do it before any other human touches it.

After a Shinigami brings a Death Note to the human world and gives its ownership to a human, the Shinigami has the right to kill the human using its own Death Note for any reason, such as disliking the owner.

The following are cases in which a Shinigami that has brought the Death Note into the human world is allowed to return to the Shinigami realm:

I. When the Shinigami has seen the end of the first owner of the Death Note brought into the human world and has written that human's name into his or her own Death Note.

II. When the Death Note is destroyed and cannot be used by humans anymore.

III. If nobody claims ownership of the Death Note, it is unnecessary to possess anyone.

IV. If, for any reason, the Shinigami possessing the Death Note is replaced by another Shinigami.

V. When a Shinigami loses track of the Death Note that he or she possesses, or cannot identify which human owns the Death Note, or cannot locate where the owner is, and therefore needs to find such information using the observation holes in the Shinigami realm.

VI. Even in cases II, III, and IV, Shinigami are obliged to confirm the death of the first owner and write down that human's name in his or her Death Note even when he or she is in the Shinigami realm.

In the Shinigami realm there are a few copies of what humans might call a "user handbook" for the Death Notes in the human world. Although Shinigami may not give the handbook to humans, it is perfectly okay for them to teach humans about its contents, no matter what that may be.

4.2 Using the Death Note
A Shinigami can extend its life by writing human names in a Death Note, but a human cannot. A person can only shorten his or her life by using the note.

Even the original Shinigami owners of Death Notes do not know much about them.

Shinigami must own at least one personal Death Note, which must never be lent to or written on by a human.

Shinigami may exchange and write in each others' Death Notes.

If a Shinigami decides to use a Death Note to end the life of the killer of an individual it favors, that individual's life will be extended but the Shinigami will die. The Shinigami will disappear but the Death Note will remain. The ownership of this Death Note is usually carried over to the next Shinigami that touches it, but it is common sense that it be returned to the Shinigami King.

By manipulating the death of a human who has influence over another human's life, that human's original life span can sometimes be lengthened. If a Shinigami intentionally does this that Shinigami will die, but even if a human does the same, the human will not die.

4.3 Shinigami Life
A Shinigami cannot be killed even if stabbed or shot. However, there are ways to kill them, which are not generally known even to the Shinigami themselves.

There are male and female Shinigami, but it is neither permitted nor possible for them to have sexual relations with humans. They also cannot have sex with each other.

As long as a Shinigami has at least once seen a human and knows his or her name and life span, the Shinigami is capable of finding that human by looking down from an observation hole in their realm.

The Shinigami realm has laws that govern it. If a Shinigami should break a law, there are nine levels of punishment, which the severity starting at Level Eight and going up to Level One, plus an Extreme Level. At severity levels above Three, the Shinigami will be punished and killed. Killing a human without using the Death Note merits punishment at the Extreme Level.

Shinigami will not die from lack of sleep. They do not need sleep, so to them it is merely laziness. Shinigami in the human world shouldn't act lazy merely because they are required to possess a human.
