Only descendants of class 3 from 26 years ago can see Misaki.That explains why only Sakakibara can see her out of the whole class: He's the son of someone from the original "cursed" class. This may be eventually made obvious; but hey, I'm only assuming from watching episode 3 of the anime.
Misaki manipulated Sakuragi into her accident because she saw Misaki.It's not like it doesn't seem possible with the tone of this series. On top of that, Sakuragi may have been able to see her because her mother too was from class 3.
People are going to die in the order they appear in the Ending sequence.
The ED and OP are going to be Evolving Credits
The myna bird's words are important.They are the last words of the original Misaki, and Reiko is involved in their death some how, either through murder or by causing an accident (or in the latter case she at least she blames herself anyway). Her apparent drunkenness/insomnia are guilt with the bird acting a bit like Poe's tell tale heart.
The only way to break the curse is to discover who the dead student is and have them leave town.
Mei can see the extra.There's got to be something about her Doll-eye. Mei mentioned being near death once due to a tumor in her eye, which had to be removed... and in Episode seven, when she reassured that Koichi is NOT the dead student, her eyepatch was off. Which gives a strong possibility that she's able to see who the extra is, or may already KNOW who the Extra is.
The Extra may in fact, be a ghost from 26 years ago whose possessing someone every year to MAKE the extra.As in, someone, some poor schmuck (most likely directly related to the ghost) is being possessed and somehow directed into being a part of Class three, therefore, causing an unbalance each year.
The Extra may be subconsciously aware of the countermeasures taken to protect Class 3 and work to subvert them.This is also assuming that Kouichi is in fact The Extra. With information given that even with the same countermeasures taken, the success rate is only about 50%. Kouichi ended up being an unexpected wildcard in the balance otherwise, and ended up triggering the calamity for that year. It could be that past years that failed were due to The Extra of that year either breaking the rules, or becoming the Forgotten and cracking under pressure to ensure people acknowledged them. It also doesn't help that Kouichi has had personal interaction with almost all of the victims so far, and present for or witness to their deaths in some way. Could be that The Extra instigates the events, and the closest ones to them for that year are the ones that died, creating more 'candidates' for the next cycle. In essence, the success of the plan relies on the will of the students in the class. For the class that had invited death in, the years it failed had students that unknowingly invited death into their lives though the acceptance of The Extra.
The people in the end of episode song background picture will liveCorrect me if i'm wrong but so far none of the people that fade into the scene have been killed, however Misaki fades OUT of the picture, possibly meaning that she will be killed by the curse.
The "Extra" is...Kouichi Sakakibara
The curse trying to kill the Extra is a Shinigami with a Death NoteThe Shinigami Realm also suffers from the dead person masquerading as an alive one, so the King tasks one of the Shinigami to kill the Extra; the problem is the Extra's influence on memories alters its own death date thus making the Shinigami eyes useless, so he start randomly killing the students until he gets the right one. Hence why a lot of the deaths are so illogical; it's because the bored Shinigami is playing around with how many ways he can kill a person. Takabayashi didn't die from a natural heart attack, but because his written death was too impossible and so the Death Note simply killed him via its usual method. Once the Extra is dead the Shinigami goes back to his usual job until the next year when another one has to do it.
There will be a sequel set in modern dayIt will involve a new class trying to stop the curse once and for all. Misaki or Kouichi might make a guest appearance as a teaching assistant or school staff. This first series would essentially be a big prologue to the sequel, which would explain why it's set in 1998 for no apparent reason.
The curse was started by a Witch.A burakumin girl (the descendants of Japan's Buddhist equivalent to the Hindu "untouchable" class, who still face some discrimination) was a member of Class 3 back in at least 1946 (26 years before the curse's previous appearance). Her family was of course rather poor, and so she wished to be able to pass the entrance exam to Yomiyama North Middle School. The class had only 25 desks (just one short), and so she was forced to stand. On top of all that, postwar Japan suffered severe food shortages, and not only could her parents not afford to make her a lunch, she had no money to buy and her classmates refused to share theirs. Eventually her grief and loneliness at being from "the bottom caste" and literally "the odd girl out" consumed her.
A Theory on the curse of 3-3.If I remember correctly, the curse is made up of the souls of the deceased. If Misaki Yomiyama was popular when he died, and people kept playing along like he was alive, maybe he never felt he died. But since people didn't talk to him like he was there, he discovered he was dead. When another student entered the class he felt angered that someone was taking his place, he wanted to be recognized. So they died and after a while the souls of the dead merged into a giant being of hate, with so many minds fighting for control, the ghost became uncontrolable.
The whole story is an tabletop roleplaying game campaign. The curse is the killer gm.It explains why the deaths and the extra are so arbitrary, why any attempt to solve the curse or well... do anything is doomed to failure, and why the curse itself appears to run mostly on bullshit(instagibs, memory control with no other limitations or rules but plot, npc mind control) The players doesn't leave because they like the other characters and don't know of any other game in the area. The gm also thinks he is a genius.
The deaths are a metaphor for sex.It's all symbolic. Kouichi just really gets around. A lot.
The lady in the doll shop is played by the same actress as the principal from great teacher onizuka.Even though she's animated.
Mei Misaki is Ragna The Bloodedge's daughterThat could explain her rather paranormal nature plus the heterochromia.
Izumi's death was the result of Reiko Mikami inadvertantly using the death curse.There was a brief scene where Mrs. Mikami shielded Mei from Takako when she thought Mei was the extra. Izumi would have killed Mei if not for that convenient bolt of lightning. This leads this troper to believe that the Extra has some degree of control over who gets to die.
The clues surrounding Reiko Mikami being the extra were there in the beginning.We just didn't see it until it was revealed to us. The first being that she couldn't stand the talking black bird. While it's not that breed, blackbirds often associate themselves symbolically with crows and ravens, which are universal birds for death. The second was when Mochizuki remarked that his crush, Miss Mikami, who was never seen in that particular episode was looking Ill. Most stories that mention an ill person are often doomed to die. In this case she was already dead. The The third and final clue, that this troper saw at least. Was when Mochizuki was blushing at the sight of Reiko in a swimsuit. Since he has a crush on only Miss Mikami, it's quite obvious who she really is at that point.
The Students knew all along who the extra was.Save for those that were investigating the Calamity, every other student were simply bullies that used the curse as an excuse to try to pull the perfect murder on Mei Misaki. Why else would they be so eager to kill her even with the evidence showing that she isn't the extra?
The Ending Credits were Izumi Akazawa's dying dream.Much of the credits show all the people happy except Mei who is disappearing. This is pretty much Izumi imagining what life would be like without Mei. She dislikes Mei and believes that everyone would have survived and be better off without Mei.
Mei's eye can hypnotize people.It wasn't until she told Kouichi "Believe me." That he didn't deliver the killing blow to Reiko. The voice it self sounded a tad hypnotic and if she can see the color of death. What's to say her eye can't do other things.
Kirika is Other Mother.She treats Mei like one of her dolls and the doll's eye can see things that should remain unseen. Somehow Mei persuaded her to give her one dolls eye. The reason why it's not a button? She switched from stuffed dolls to glass eyed ones.
The Curse actually is a curse.An earlier WMG states that it isn't really a curse because it bears no actual malice. I believe it does - the point of the curse is to draw upon the ugliness of human nature. It's a curse specifically designed to seem like it just happens, that there's no real reason for it, to make the ensuing panic even stronger. What's worse? - knowing that your class is cursed, and by knowing that, knowing there's a way to lift the curse, or that horrific death is just going to happen for no good reason. The ability of the curse to seem more like a force of nature causes the people of Yomiyama even more pain. Not only are the students of Class 3 constantly in fear for their lives and the lives of their loved ones, it draws out their suspicions of those different from them, because anyone could be the Extra. It takes away their compassion and their value of human life, and ultimately drives them either insane with fear or to murder. The curse is not only a curse, but more malicious than anyone in Class 3 realizes.
