Aoba will become yandere for Mikado
Mikado manages the online dating site that Tom Tanaka and Shizuo work for
Certy is one of The Stig's cousins...and it follows that The Stig is a Dullahan.
Izaya is an older alternate universe version of Araragi
Mikado is a Vocaloid
Kasuka Heiwajima is directly descended from Huey Laforet.Huey Laforet has a habit of fathering/grandfathering/great-grandfathering look-alikes, and damned if Kasuka doesn't have an eerie resemblance to him. It doesn't help that Huey has a great-grandson that looks and acts almost exactly like Kasuka.
The characters are incarnations of the deities from Norse MythologyWell, Celty might be a Valkyrie, and with his constant manipulation of others, Izaya seems an obvious fit for Loki, and maybe Shizuo is either Thor or Baldr- he hates Izaya on sight because of what Loki did to him. Anri is Freyja- one of her roles was leading the Valkeries, hence the sword she carries, and while Freya was a love goddess, since this is Japan, she was incarnated as a moe schoolgirl. Kida also seems like a good Thor candidate, given his jovial manner and not being that bright. Finally, I could see Mikado as Odin- he pursues wisdom and is really good at getting people to follow him.
Izaya is NaoyaNaoya is Cain, who will reincarnate until he does something that he's too pissed off to do. Izaya looks JUST LIKE him. It also explains why Izaya wants to cause Ragnarok. Can't reincarnate if there's no world to reincarnate to, right?
Izaya is an extremely out-of-his-mind Nozomu Itoshiki.One too many cases of despair broke the teacher's mind and transformed him into a Magnificent Bastard with the desire to spread despair onto others.
Walker and Erika are Reality WarpersSpoilers for Simon and Chief Chef's backstory: Walker and Erika's fabricated backstory for the staff of Russian Sushi is way to close to the truth for it to be mere coincidence, and you'll notice that that The Mafiya doesn't make any sort of presence in the series until after they conclude Simon and Dennis are ex-KGB and on the run from Russian weapon dealers. The reason? Because Walker and Erika didn't just guess their past, they willed it into existence. Kinda puts Walker and Erika's comments about "choosing" the bits reality they want to be real into a new light, huh? As for why Shizuo/Izaya (or Kadota/Chikage) isn't canon if this is true, it's because they have to be in agreement for it to work.
Shizuo and Kasuka have fae or otherwise supernatural ancestryWhen Shinra is brought in to treat the quarter-Dullahan Ruri Hijiribe, he's amazed to find that the unusual properties her body has (Super Strength, an accelerated Healing Factor, and nigh-impenetrable muscle tissue) are almost identical to Shizuo's. The official explanations for Shizuo's Super Strength are a lack of mental blocks and plain old Charles Atlas Superpower, but what about his ability to bounce back from otherwise crippling injuries, or the fact that his body is tough enough to break steel scalpels? And his brother is hardly normal either, what with simultaneously being a hypercompetent Ace and an ice-cold, robotic Stoic. The answer might be that the Heiwajimas aren't entirely human. Given that we know very little about their parents (other than that they're alive and they weren't abusive), and that human/nonhuman offspring have been proven to be possible via the aforementioned Ruri, it's entirely possible for both of them to have some inhuman blood themselves — if not fae, then possibly youkai or demonic (the Naritaverse is practically an Urban Fantasy Kitchen Sink, after all).
Saika is possessed with the spirit of Graham Specter.No seriously, listen to him talk and then listen to Saika talk about humanity. Considering Durarara and Baccano share the same universe, surely by the time of Durarara, Graham's been dead for a few years. Granted, I'm not sure why he'd be in a sword and not a wrench, but there you go.
Izaya is actually Prussia from Axis Powers Hetalia.I mean, he's not a country anymore, he's gotta have a lot of free time. He just got his hair dyed.
Izaya is Tite Kubo.Because seriously, who else could match that level of stylishly evil Trolldom?
Yamaha will discover Psyche and Tsugaru, get Hiroshi Kamiya and Daisuke Ono, and turn them into Vocaloids.There's gotta be a reason why they're drawn with nail polish so often.
Celty isn't actually a being from Celtic nor Norse mythology.More like an Eldritch Abomination like Baccano!'s Ronnie Sukiart. This came to me suddenly when I watched Baccano! just now, the episode when they reveal Ronnie as the 'demon'. I mean, Celty's able to make fucking clothes with her smokin' power, why not a body? Her memories as a Dullahan could be because the demons were faes. Maybe it was some sort of demons' quirky trait (Ruri Hijiribe's granddad is rumored to be a Dullahan, too, if I'm not mistaken.) so they just hung out with heads unattached, some with butterfly wings, others with pointy ears, etc. Maybe even those myths actually started from humans who saw those crazy circus freaks walking by and promptly thought they were divine beings.
Aoba snapped at Izumi because he was sexually abused.His brother mentioned that he beat up Aoba often because of an inferiority complex. But then he mentioned that he went too far this one time and then Aoba got him back by setting his room on fire. Izumi then states that Aoba took all the physical abuse and never complained about it. When you put this info together, something that was out there like rape might have done it in. And since Izumi would resort to kidnapping and later attempted murder, he might as do this.
Shinra is a Yandere.Think about it: His first meeting with his future love interest involves cutting her open. He lives with said woman for twenty years- it's implied that over the years he didn't think of anyone other than Celty as a potential love interest- and constantly says she'll be his future wife. He does basically everything in his power to keep her from finding her head, just because if she does she MIGHT leave him. He insists on marriage only, something that would bind her to him through legal means. And he does it all while smiling that creepy little smile.
Izaya is an incarnation of Loki.Or he deliberately acts like he is, to troll other people with passing knowledge of Norse Mythology and the audience.
Simon was once forced to eat human flesh in the pastSimon is awfully insistent in making sure everyone knows that there's no human flesh in his sushi. Now the normal conclusion for this sort of thing, considering the setting, would be that he and Dennis have some sort of Sweeney Todd thing going on, but this seems unlikely, given his pacifist nature and status as The Atoner. So why is he so hung up cannibalism? One possible explanation is that, somewhere in his Dark and Troubled Past, Simon wound up in a Donner Party-esque situation (maybe some secret KGB mission gone wrong) where his options were to eat the flesh of his already dead comrades or starve to death. He came out alive and sane, but was understandably traumatized by having to eat his buddies and is still a bit hung up about it. So, while the fist question that comes to most people's minds when encountering strange food usually isn't "Hey, this Russian sushi doesn't have people in it, does it?" it's the fist question that comes to his mind, which is why he keeps mentioning it.
Walker is a descendant of Tick/Chic Jefferson from Baccano!There's already speculation that Walker is part American. And their smiles are just way too similar.
Celty sucks at lying because she's a DullahanDullahans are Fey. One of the elements of The Fair Folk? They can't lie - except instead of the traditional interpretation, Naritaverse faeries "can't lie" in that they suck royally at it.
Izaya's Past has to do with ShinraThey never explain how Shinra became friends with such a jerkass. It would also explain why bringing up the incident in middle school shuts Izaya up and knowing Izaya, it must have been REALLY bad to get him to be quiet. In other words, Shinra might hold the key to Izaya's weakness.
Izaya is going to end up killing someoneThis troper has a really bad feeling that Izaya is heading in this direction. His past with Shinra proven above has him state that he's going to make the person who stabbed Shinra suffer for the rest of his life. And what we've gotten from volume 9 so far he's very close to nailing said person (Nakura).
Izaya is possessed by a Saika counterpartHe claims to love all of humanity like Saika and hurts people because of his "love." His weapon of choice is a knife, and he can do seemingly impossible things with it, like shave a guy's head from yards away. His rampant use of Insane Troll Logic is because an enchanted blade's logic is nothing like human logic. However, unlike with Anri, or even the other characters posessed by Saika, Izaya fully absorbed the blade into his human body and was victim to a Split Personality Takeover. Becoming human and therefore mortal was a shock for an immortal blade, which is why he has such a strong fear of death that he'd come up with such an insane scheme to find an afterlife for himself.
Shizuo is going to go to ValhallaThat's why Celty is on Earth; she's waiting for him to die. If Shingen hadn't stolen her head and went to Ikebukuro, Shizuo would have ended up in Ireland for reasons he couldn't explain. They're noted to have a strange connection neither of them can explain, but it isn't love. She also fangirls around him when he does really impressive things. So the series is going to end like this: Izaya will have his war, and will manage to kill Shizuo. Then Celty's head will awaken, and she'll go full Valkyrie. She'll grab Shizuo, ignore Izaya completely, and then promise Shinra she'll come back to him.
Shinra is a closet masochistThink about it. He doesn't mind getting smacked, punched, slapped, kicked or even freakin' strangled by Celty, and it's even implied that it ''arouses'' him. Adding to this, there are times when it seems like he's bugging Shizuo just to goad him into punching him. He also never seems to care when he gets injured. Plus, the idea is really funny.
Durarara takes place in the near future, where anonymous has become a physical organzationAnd goes by... the dollars.
The crime that Izaya framed Shizuo for has to do with taxes or something credit relatedIt would explain why Shizuo can't hold a proper job anymore and why his younger brother wanted him to keep a steady job so badly. This troper figures that something simple may be too little for Izaya to pull off, but he is a total jerkass and would stoop to petty crime like this to get something done.
主角，Celty Sturluson, 是死神She carries a scythe and uses it to chop down those she sees fit.
Yadogiri Jinnai is the manager of Shizuo's debt collection company.We only know a few things about the manager. In Shizuo's flashback in the novels, the manager gets mentioned as one of the people who isn't scared of Shizuo, and the narration says "He knows how to deal with Shizuo". Right afterwards, it brings up Simon and specifically states that he can protect himself from Shizuo, so it's almost certain that the manager deals with Shizuo in a way besides violence. We know from Jinnai managing Ruri that he knows how to handle unstable people with superhuman power. Another clue comes in the 9th novel when Tom talks to Vorona about Shizuo being late, due to serving as a bodyguard for the manager, who states has plenty of enemies. Who has more enemies than Jinnai? Not to mention just the fact that we haven't had even a name for the manager mentioned, much less an appearance. And this is Narita, where 99% of the cast is a huge badass and/or epic troll. I don't think he'd hold off so long on showing a character that closely connected to Shizuo for no reason.
The Big Bad of the series isn't Izaya, but Mikado.Because we all know it's coming...
Mikado will marry Anri.Not because teach her how to love again, but because she comes to depend on his protection.
Saika is the Soul Embrace, aka Broken Destiny from the Soul Series "purified" of its evil.Soul Calibur's wielder at the time, probably Mitsurugi was able to defeat Soul Edge for good. In the end Talim (who seemed to be able to purify Soul Edge in her SC 2 ending), Taki (who was trying to destroy the swords), Ivy (for revenge and atone for her sins serving under Nightmare) or Kilik (who can wield a similar Soul Embrace weapon) was able to purify the sword. The purified sword wanted to follow Soul Calibur's agenda of being "the light of humanity" (like in Cassandra's Soul Calibur 4). That is why Saika loves humanity and its flaws wanting to create a perfectly ordered world. In its sealed and weakened state could not freeze the world like it tried to in Siegfried's SC 4 ending. The sword did retain Soul Edge's corruption abilities and knack for weapon creation. From Soul Calibur it kept its subtle powers like healing, no longer thirsting for souls. It made a plan of saving the world by enslavement and its warriors like Shizuo Heiwajima. Just like how Krita Yuga became Soul Calibur, it will awaken to a world already enslaved. Unlike Soul Edge who is destructive it bides its time. Until then it loves humanity, one cut, one slash at a time.
Izaya is the Master.Because i think it's pretty clear Izaya's not human. He and the Master are both Faux Affably Evil Magnificent/Manipulative Bastard Psychopathic Manchildren with plenty of Foe Yay. After The End Of Time, he fled to Japan and regenerated. Izaya's fear of death could be related to why the master never dies, even when he's supposed to.
Black Butler is related to the Narita-verse somehow.I've seen a whole bunch of things connecting Durarara!! and Black Butler, such as AMVs and fancomics. While I am aware that these are not canon, Black Butler takes place roughly around the late 1880's, which would leave plenty of time for Baccano! to occur without a hitch, and due to the Fantasy Kitchen Sink of the Narita-verse. Which leads to this...
Izaya is somehow related to Sebastian MichaelisSeriously, think about it. They look a lot alike (black hair, red-colored eyes); both have serious rivals (Shizuo and Claude), whom they are often paired with in fanfiction; they both have in-universe fangirls; have people close to them that act cold towards them but are actually close to (Namie and Ciel); both are feared; both are Stepford Smilers, and so on...
The goth-loli girl that passed by Mikado and Kida in the first episode is Haruhi Suzumiya.Why the heck not.
Rokujou Chikage from the novels is the son of Firo and Ennis from Baccano!He got his fashion sense from his parents, his ladies' man attitude from Uncle Claire, and his battle skills from... everybody. How he wound up in Japan leading a biker gang is a bit of a mystery...
Izaya is a changelingOkay, I admit that I got the idea from a fan fic but it explains so much. How he manages to move so fast (remember when he shaved that guy's head?), his attitude towards humanity, the trolling (The Fair Folk have a history of messing with humans for the lulz after all). He may not know that he isn't human but his true nature shows all the same. Vending machines used as projectile weapons? Controlling masses of people for the greater good with eerie red eyes as a side effect? Everything manipulated by a Magnificent Bastard / Jerk Ass named after a biblical figure? Perhaps all of the events come out of a twisted competition to see which of Joshua and Izaya can most effectively drive the inhabitants of their city to despair...
Meta-WMG The dub decided not to cast Stephane Sheh for Anri because they didn't want to deal with the Actor Allusion results that the fandom would inevitably produce.Anri falls within Sheh's typecast: teenage girl (or appears to be one) with huge breasts and severe emotional issues resulting in something from eccentricity to insanity. However, since the dub knew they were getting the 12:30 AM Sunday timeslot, they didn't want to be overshadowed by Bleach, so they avoided casting Sheh in order to be taken seriously.
Izaya has Sadistic Personality DisorderI was reading a Cracked.com article the other day that described the symptoms (long story), and all I could think was "That sounds just like Izaya!" He "loves" humans, and enjoys getting them into all sorts of horrible predicaments because it amuses him. The reason he hates Shizuo so much is because he's the only person Izaya can't screw with, but he makes up for that by pissing him off for the hell of it. Seriously, Izaya is this!
Shizuo's agency belongs to Nebula or some other Giant CorporationThink about it. The agency pays for the repairs caused by Shizuo (which, considering his Hair-Trigger Temper and tendency to destroy everything when angered, is no small amount) but still can afford to pay the employees' salaries (including Shizuo's), and shows no sign of going bankrupt.
There will be an arc focusing on the Seven Deadly Sins.With everything the series has covered so far, it wouldn't be surprising. In particular:
Takashi Nasujima has a daughter. Her name is Shoko Yuasa.
The reason Saika hates monsters, non-humans and IzayaIs because she's afraid that if she cuts one and turns it into a daughter blade, it will try and take over, eventually becoming the new Mother.
Aoba is a Humanoid Abomination of some sort.The best evidence I can give is that the boy is eerily skinny (even by this show's standards) and he has giant eyes that appear to glow in one picture◊. Most scenes seem to imply that he has some mental effect on people, too.
The whole series is a prequel to Shin Megami TenseiJudging by the whole urban/mythological thing they got going on. In DRRR you have a reaper in the germanic sense, with influence from irish and norse mythos, as well as a possessed blade clearly influenced by eastern mythology. Add lovecraftian demons in Baccano. What other series mixes these mythos into a single one? Shin Megami Tensei. Also, as I mentioned, the urban theme is very similar, as well as the fight between order and chaos. There aren't many references to abrahamic religions, and I don't know how well Vamp fits in, as I haven't read it, but I wouldn't be surprised the way the story plays out to have Mikado get an email about a summoning program. Come to think of it, the schoolkids kind of match up to the original heroes of SMT: Lawful: Mikado Female: Anri Chaotic: Masaomi The protagonist would probably be a newcomer to the arc.
Shizuo and Izaya are in a kismesissitude and, being humans, don't realize it.C'mon! You'd have to be blind not to see it!
Izaya will gain possession of the Death Note.It is just me or is that the singularly most terrifying thing you can think of?
Izaya is literally forever 21Since this is the same universe as Baccano! Izaya found (or will find) a way to become immortal. Or maybe he already is.
