Late Halloween Post (important update)

First of all, sorry that I haven’t been posting over the past couple of months but I simply haven’t had the time nor energy to research and post to my blog. This is largely due to college keeping me especially busy this year. From now on (unfortunately) I won’t be making regular blog posts. It’s going to be strictly when and if I have the time and energy. If I do, then I’ll make an effort to post (but no promises). Anyway, enjoy!

As we are all aware, Halloween was just under a week ago. I spent most of my Halloween at college but (to make it a bit more fun) I went in fancy dress. I donned a dress shirt, black trousers and styled my hair to look like Light Yagami from Death Note (one of my favourite animes of all time). I also went a step further and coloured in one of my notebooks to make it look like a Death Note and hid a couple of pages from it in my shirt’s collar and one hidden in my belt (no watch trick unfortunately).

As it turns out, I have a lot of friends who have never watched Death Note (blasphemy, I know) and they were wondering how it works. At that point I told them to check my blog and said that I’d post all of the rules of the Death Note there. So for all of you people who are getting into Death Note this is…

How to use the DEATH NOTE

Writing Names

  • The human whose name is written in the DEATH NOTE shall die. This human will only die if the person who wrote the name has the human’s face in mind (that way, people who share the same name will not die).
  • The DEATH NOTE will never affect a human whose name has been misspelled 4 times.
  • If a DEATH NOTE owner accidently misspells an individual’s name 4 times, that individual can no longer be killed by the DEATH NOTE. However, if the owner intentionally misspells the name four times, the owner of the DEATH NOTE will die.
  • When the same name is written in 2 or more DEATH NOTES, the DEATH NOTE that was used first will take effect (regardless of time of death).
  • If the same name is written in 2 or more DEATH NOTES within a margin of 0.06 seconds then the entry is regarded as simultaneous. As a result, the individual shall not die.
  • The DEATH NOTE will not take effect if the victim’s name is written on multiple pages. However, the front and the back of a page are considered to be one page. For example, the DEATH NOTE will still take effect if the victim’s last name is written on the front page and first name on the back.

Entering the Causes and Conditions of Death

  • If the cause of death is written within 40 seconds, it will happen.
  • If the cause of death is not specified, the victim will die from a heart attack.
  • After writing the cause of death, the details of death should be written within the next 6 minutes and 40 seconds.
  • If the time of death is specified within 40 seconds after writing the cause of death, the time of death can be manipulated and can go into effect within 40 seconds after writing the name.
  • The conditions of death will not go into effect unless it is physically possible for that human or it could be reasonably assumed that the human could carry them out.
  • Since the limitations applying to the conditions of death are unknown to the Shinigami, the DEATH NOTE owners must find out on their own.
  • You may write the cause/details of death prior to filling in the name of the individual. Be sure to insert the name in front of the cause of death. You have about 19 days (according to the human calendar) to input a name.
  • Suicide is a universally valid cause of death as all humans are thought to possess the potential to commit suicide. It is, therefore, something that can be reasonably assumed of an individual.
  • Whether the victim’s cause of death is suicide or an accident, if it would lead to the death of someone other than the intended victim, the person will simply die of a heart attack (to ensure that other lives aren’t impacted).
  • After an individual’s name, time of death and conditions of death are specified in the notebook, the time of death and the conditions of death can be altered as many times as the user wishes (as long as they are changed within the aforementioned 6 minutes and 40 seconds). This is, of course, only possible before the victim dies.
  • If you write “Dies of accident” as the cause of death, the victim will die from a natural accident 6 minutes and 40 seconds after the time of entry.
  • Even if only one name is written in the DEATH NOTE, if the victim’s death causes other humans that are not written in it to die, the cause of death will default to a heart attack.
  • If you write “Dies from disease” and specify which disease and the time of death, there must be a sufficient amount of time for the disease to progress. If the set time is too tight, the cause of death will default to a heart attack 6 minutes and 40 seconds after the time of entry.
  • If you write “Dies from disease” and specify a time of death, but not a disease, the victim will die from a plausible disease.
  • The DEATH NOTE can only operate within a 23 day window (according to the human calendar). This is referred to as the 23 day rule.
  • If you write “Dies from disease” and specify a disease, but not a time of death, regardless of how long the disease takes to progress; the 23 day rule will not take effect. Furthermore, the human will die at an appropriate time (depending on the disease). Note: While you may still re-write the cause of death and the details of death (within the 6 minutes and 40 seconds), you may not change the time of death (however soon it may be).
  • In order for the DEATH NOTE to take effect the victim’s name must be written on one page; however, the cause and conditions of death may be entered on other pages. This will work as long as the person who writes in the DEATH NOTE keeps the specific victim’s name in mind when writing the cause and conditions of death.
  • If the cause and conditions of death have already been entered before the victim’s name, multiple names can be written in. This will only work if they are written in within 40 seconds and the cause/conditions of death are not impossible. In the event that the cause of death is possible but the conditions of death are not, the cause of death will still take effect (if both are impossible then it defaults to a heart attack).
  • When you write multiple names in the DEATH NOTE and then write down one cause of death within 40 seconds of writing the first victim’s name, the cause will take effect for all the written names. Also, after writing the cause of death, even if the conditions of death are written within six minutes and 40 seconds in the human world, the conditions will apply only to the victims for whom they are possible. Those for whom the conditions are not possible will simple die from the specified cause of death.
  • A human death caused by the DEATH NOTE can indirectly lengthen the original life-span of another human (even without the user’s specific intention to do so).
  • Once the victim’s name, cause of death and conditions of death are written down in the DEATH NOTE, that death will take place (even if that DEATH NOTE or the page of the DEATH NOTE used to write down the details is destroyed).
  • If the victim’s name has been entered in the DEATH NOTE and the DEATH NOTE is destroyed before any other information (time of death, conditions of death, cause of death, etc.) could be entered, the victim will die of a heart attack in 40 seconds after the entry. If the cause of death was entered before the DEATH NOTE was destroyed, then the victim will die from that cause of death in 6 minutes and 40 seconds after the entry (but only if it is possible within that time). If it is impossible for the victim to die via the entered cause of death, the cause of death will default to a heart attack.


  • If you wish to change anything that was entered into the DEATH NOTE you must do so within 6 minutes and 40 seconds. To erase from the DEATH NOTE you must rule out the characters you want to erase with 2 straight lines. While the time of death, conditions of death and the cause of death can be erased, the victim’s name cannot. Once the victim’s name is written into the DEATH NOTE, that individual’s fate cannot be averted.
  • Attempting to erase and/or white out names in the DEATH NOTE is useless.
  • Even if a new victim’s name, cause of death, or conditions of death are written on top of the original victim’s name, cause of death, or conditions of death, there will be no effect on the original victim’s death. The same thing will also apply to erasing what was written with a pencil, or whiting out what was written with a pen.


  • The DEATH NOTE will not affect those less than 780 days old (2.1 years old).
  • You cannot kill humans who are over 124 years of age with the DEATH NOTE.
  • You cannot kill humans with only 12 minutes of life left (according to the human calendar).
  • You cannot set a time of death after a human’s lifespan. Even if you do, the victim will die before your intended time.

Other Things to Consider

  • Any human who uses the DEATH NOTE (even if only once) cannot go to Heaven nor Hell.
  • One page taken from the DEATH NOTE (or even a fragment of a page) possesses the full power of the DEATH NOTE.
  • You can use anything to write in the DEATH NOTE (cosmetics, blood, etc.) 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 DEATH NOTES have red or white covers. They are no different than the original black DEATH NOTES.

The Beginning of Ownership

  • The DEATH NOTE shall become the property of the Human Realm the second it touches the ground.
  • The owner of a DEATH NOTE can recognise the image and voice of the original owner (this will typically be a Shinigami).
  • Whenever a Shinigami dies in the Human Realm and leaves behind it’s DEATH NOTE, the note’s finder automatically becomes the new owner. However, only a human that can see and hear the Shinigami in question is able to see and touch their DEATH NOTE. As unlikely as it is, if another Shinigami happens to find this DEATH NOTE by chance; that Shinigami will become the new owner of that DEATH NOTE.
  • If you happen to lose the DEATH NOTE or if it gets stolen from you, you will lose ownership of that DEATH NOTE unless you can retrieve it within 490 days.
  • If the owner of a DEATH NOTE dies while loaning it to someone, the DEATH NOTE automatically becomes the property of the person it was loaned to. Similarly, if the DEATH NOTE is stolen and the original owner is killed by the thief; the thief becomes the new owner of that DEATH NOTE.
  • Anyone who loses ownership of the DEATH NOTE will lose all memories of it. They will not lose all memories from the period of ownership however (only the memories involving the DEATH NOTE).
  • If a human who possesses ownership of 2 or more DEATH NOTES loses ownership of one of the DEATH NOTES, they will no longer be able to see or hear that DEATH NOTE’S Shinigami. The Shinigami will then leave. Note: The original owner will not lose their memories of the DEATH NOTE (as long as they retain ownership of at least 1 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, all of the memories associated with that DEATH NOTE will also return. In cases where the owner was involved with multiple DEATH NOTES, they will also regain the memories of those DEATH NOTES. Note: The memories of a DEATH NOTE will return so long as you touch it (you do not have to claim ownership of it).
  • Even if you do not actually possess the DEATH NOTE, you may still use it to its full effect.
  • You may lend the DEATH NOTE to another without forfeiting ownership of the DEATH NOTE (the borrower may do the same).
  • 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.
  • In the event that someone does borrow a DEATH NOTE, the borrower will not be followed by a Shinigami (nor can they trade for the Shinigami Eyes).
  • Only by touching each other’s DEATH NOTES can owners recognise the appearance and voice of another owner’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.

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 6 DEATH NOTES may exist in the Human Realm at any one time. DEATH NOTES carried by Shinigami are not counted. This means that only 6 Shinigami who have passed on their DEATH NOTES may be in the Human Realm 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 (though this is extremely rare).
  • Should a seventh DEATH NOTE be passed on to the Human Realm, 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.

The Shinigami Eyes

A human who owns a DEATH NOTE may agree to make a deal with that DEATH NOTE’S Shinigami. If the human is willing to trade away half of their remaining lifespan, they will receive “The Eyes of a Shinigami”

An Individual with Shinigami Eyes will be able to see a person’s name and their remaining lifespan just by looking at their face. I also need to mention the fact that the name they see is the name that they would need to write in the DEATH NOTE to kill you (they will see this name even if it is not registered anywhere). This of course makes them especially dangerous (as they no longer need to find out what your name is). It should be noted that simply owning a DEATH NOTE makes it impossible to kill you with a DEATH NOTE. For this reason, humans who wield a DEATH NOTE cannot see the remaining lifespan of other DEATH NOTE owners (even with Shinigami Eyes).

This can be used as a means of finding DEATH NOTE owners if you to own a DEATH NOTE.

There is one countermeasure to deal with those who have made the Shinigami Eye Deal. Those with Shinigami Eyes need to see at least half of your face to learn your name and your remaining lifespan. When looking from top to bottom, they must be able to see at least from the head to the nose. If they look at only the eyes and under, they 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 they can basically see the whole face they will be able to see the person’s name and lifespan.

To make matters worse, I have found no ways to distinguish between a human who does have the Shinigami Eyes, and a human who does not. Take precautions against any DEATH NOTE owners you encounter since there is a chance that they may have the Shinigami Eyes (and there is no way to tell if they do or don’t).

Please be aware that (despite my extensive research into this topic) I am still uncertain as to exactly how much exposure is required before a human with Shinigami Eyes can see your name and remaining lifespan.

What I can say for certain is that, if the above conditions are met, then anyone with the Shinigami Eyes can identify you. Furthermore, if someone with the Shinigami Eyes sees a picture of you (with your face uncovered) they will identify you (no matter how old the picture is). This can however vary based on the resolution and size of the image. Furthermore, drawings of you cannot be used by one with Shinigami Eyes to identify you (regardless of how realistic it may be).

There may be no way to physically distinguish between those with the Shinigami Eyes but it should be mentioned that those with Shinigami Eyes will have eyesight of over 3.6 (regardless of what their eyesight used to be).


The Shinigami Rules

  • The human owner of a DEATH NOTE is possessed by a Shinigami until he/she dies or they forfeit ownership of the DEATH NOTE (whichever comes first).
  • If a human uses a DEATH NOTE, the Shinigami must appear in front of them within 39 days of the human’s entry.
  • The original Shinigami owners don’t (in principle) do anything about lives ended or saved as a result of the human’s DEATH NOTE usage. Nor do they attempt to help or prevent the deaths brought about by the DEATH NOTE.
  • A Shinigami has no obligation to inform a human owner on how to fully use the DEATH NOTE or the rules that apply to those who wield it (I learned this one the hard way).
  • The Shinigami must not tell humans the names or lifespans of anyone they see.
  • 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.
  • A Shinigami may not remain in the Human Realm without a reason. There are 3 reasons that have been deemed as acceptable reasons for a Shinigami to reside in the Human Realm for an extended period of time:
  1. When a Shinigami’s DEATH NOTE is handed to a human.
  2. If a Shinigami is finding someone to wield their DEATH NOTE (this should be done from the Shinigami Realm but it is okay as long as this is done within 82 hours (according to the human calendar)).
  3. When a Shinigami stalks a human with the intention of killing them (again, this must be completed within 82 hours).
  • A Shinigami may not hand their DEATH NOTE to any human under 6 years of age (human calendar). Loophole: A Shinigami can drop their DEATH NOTE anywhere they wish, and then anyone who picks it up can use it (even if they are under 6 years of age).
  • 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.
  • Shinigami reserve the right to kill the owner of their DEATH NOTE at any time, even for a reason as trivial as disliking them (so if you want to live long, don’t piss ‘em off).
  • The following are cases in which a Shinigami, that has granted ownership of its DEATH NOTE, has been allowed to return to the Shinigami Realm:
  • 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.
  • When the Death Note is destroyed and cannot be used by humans anymore.
  • If nobody claims ownership of the Death Note, it is unnecessary to possess anyone.
  • If, for any reason, the Shinigami possessing the Death Note is replaced by another Shinigami.
  • 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.
  • 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.

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 other’s Death Notes.
  • If a Shinigami decides to use a Death Note to end the life of the killer of an individual it favours, 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.

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.

Those are all of the rules that I am currently aware of as of now. Be warned that I have also learned of the existence of fake rules that have been made up for various reasons. I cannot be sure that I know all of them so watch out for them.

Fake Rules

The following are rules that were made up in the Death Note anime that ARE NOT REAL DEATH NOTE RULES:

  • If you make this note unusable by tearing it up or burning it, all humans who have touched the note until then will die.
  • If the person using the note fails to consecutively write names of people to be killed within 13 days, then the user will die.

I hope that you enjoyed this post and, if so, please leave a comment to tell me what you liked about it. Similarly, if you thought this post was absolute dog shite then please feel free to leave a comment and tell my why this post was so awful.
