Mai's fake love confession was real.Being a quiet girl further isolated by her rather odd sense of humor, Mai is enamored by Yukko, a lively girl who opens up to her and partakes in her own unique brand of "humor". When Yukko panics in a fluster from her confession, Mai quickly diffuses the situation by calling it a joke. She'd rather let Yukko believe she was trolling her rather than sacrifice the few friends she has. Whether the trolling for the rest of the series is Mai's way of bonding with her friend's love of humor or the result of passive-aggressive heartache is up to interpretation.
Everything is happening exactly as you see it.All the Mundane Made Awesome scenes and Imagine Spots are actually happening. Things really slow down and get dramatic, Misato is really shooting Sasahara (and he is really walking away injury free), people actually turn Blue with Shock or experience Color Failure, etc. The rules of the world in Nichijou work slightly differently than in our world and this really all is just everyday life.
Professor isn't really a child. She's an adult who de-aged herself.Nano is simply taking care of her until she either finds a way to return to her original age or returns via The Slow Path.
The teacher in this clip is older Yukko.Yukko mentioned that she wanted to become a teacher in the future, and they surely look alike. This also explains why she's this nice to the students - Yukko did have some troubles in school, after all, and would know that feeling.
This show is the world seen through Osaka's eyes.For starters, she's Nano and Chiyo is the Professor. Mai is what she imagines she'd look like if she were Sakaki.
The show takes place in the Gag Manga Biyori-verseIn the third season of Gag, a robot shows up who acts very much like a human, yet has a lot of weird functions, just like Nano. No, they aren't one and the same (the robot is jerkish, Nano isn't et.c.), and the Professor didn't create the other robot, but this suggests a similar technology branch in the verse(s) of these shows.
Nano was not created by the Professor, but by someone who needed to oversee her safety without being there themselves.Even though she knows enough to modify Nano without her knowledge (Nano may not have shipped with the key), she doesn't have the heart to reverse-engineer (if she doesn't know, how to do that in the first place) her to make her a servant instead of the other way around.
Half of the show is actually about Yukko.Recent episodes are putting an increased amount of focus on the abuse she takes daily. Granted, it's mostly her fault due to her not controlling her Hot-Blooded and Book Dumb tendencies. She also stars alongside Nano in the ending sequence.
"Hakase" is actually the Professor's real nameHakase (博士), meaning "expert" or "learned one", is an honorary way to address doctors or professors. Spelled with different kanji (葉加瀬) it's also a fairly common Japanese family name. Since in the manga "Hakase" always gets spelled in hiragana (はかせ), it could even be the girl's given name, although that is a bit unusual. In any case, it could well be that Nano is calling her by a proper name rather than a title.
"Helvetica Standard" is the Nichijou of their universe
"Helvetica Standard" is the future of the Nichijou universeProfessor grows up and makes more awesome/weird inventions, so either Reapers, angels, tengu and such like are said inventions, or it's that normal people can see them now. All the while she and Nano (who went through some cosmetic changes) sit in a cafe and complain that coffee isn't "coffee-coffee" enough.
The Professor based Nano's design on someone she knowsEither consciously or subconsciously, the Professor designed Nano's appearance on someone she's met. Hilarity shall ensue when Nano and her "original" meet up.
Nano had a Restraining Bolt about the windup keyThe Professor installed a Restraining Bolt on Nano's programming to prevent her to remove the key on her back herself. That is why she kept asking the Professor to remove it, although Mio's sister showed that it could be easily taken off.
The reason why the show is called Nichijou......even though nothing on the show is really "ordinary" is because it's partially based off of things in the MLIA site. Seriously, go here, and you'll start thinking that either the people on the site can't define "average" or that maybe life isn't as normal as we think it is...
The real reason why the show is called Nichijou...It's about Nano trying to get an ordinary life, and the things around her are anything but.
Nano was created in the future by the Professor to take care of her younger past self.And Nano doesn't realize this, which is why she keeps asking the 8-year-old Professor to remove her key when she only refuses. She doesn't refuse because she doesn't want to remove it, she refuses because she doesn't know how! This may not explain how she is still able to install small features into Nano at that age however.
Igo-Soccer is someone's practical joke Gone Horribly RightSomeone invented Igo Soccer as a nonsense game just to see who he could trick in to playing it... then it snowballed.
Misato and Mio will have a kendo fight for Sasahara's affections.In the course of it, Misato will bring out her weapons, and Mio will unleash the Wood Cubes. And it will be awesome.
Kana Nakamura is the original owner of Sakamoto-san.She wasn't just chasing after a cat that looked like him because it would provide her more information about Nano's machinery!
Mai isn't a Troll, she just has No Social Skills.A lot of Mai's more trollish actions make as much, if not more sense, when you consider Hanlon's Razor — "Never attribute to malice that which is adequately explained by stupidity."
The Principal is related to the Professor.Episode 26 noted, the Principal's surname is "Shinonome". If this isn't just mere coincidence, it explains a lot about how the Shinonome Lab is able to get by when nobody is employed, and also how the Professor got Nano into school in the first place.
Yuuko has a learning disability.In those few times she actually bears down to study, she is unable to stay focused for more than 10 seconds. It is only through a miracle that she scores as high as 80 on a quiz legitimately.
The Professor is the granddaughter of Dr. Gero.She can make a android and she gave Sakamoto, of all things, a RED scarf.
There's only so much Awesome go to around.In the Nichijou-verse, there's a set amount of Awesomeness given to each individual or group of individuals. This is why so many characters can do such over the top things like turn the three-second rule into a scene from Dragon Ball, or a tsundere express her tsun-tsun side with heavy weaponry. This is also why the scenes featuring Shinonome Laboratories are so mundane by comparison. As a mad scientist child, wind up robot, and talking cat, the Shinonome are so bizarre by default that there's no very little extra Awesome to go towards having those same kinds of scenes.
The oddball stuff in the show is all in Yuuko's head.Think about it. All the really out there, or extremely exaggerated stuff in the show (Principal wrestling Deer, Mio's assault on the cop, the Wooden Cubes' origin, etc) has Yuuko present or in the case of the cube origin, sees the cubes change. What if, considering the fact that she doesn't seem to really care about school, these events are her daydreaming? Maybe their lives really are ordinary, but we see the show through Yuuko, and we see what she thinks.
The Professor isn't the real Professor Shinonome.This is a theory that combines a few WMG here. The Professor's father is the real professor Shinonome and owner of the lab Nano and Professor live in. Being a bit of an Absentminded Professor, he named the Professor "Professor" / "Hakase" in hopes that he would be able to teach her everything he knew about science. He homeschooled the Professor to do so, giving the reason why she doesn't go to school. Eventually, Professor Shinonome had to leave to go do science somewhere, and he built Nano to take care of the Professor while he's gone. With her father abroad, the Professor believes that she has inherited the title and responsibilities of being Professor Shinonome, but the only real things she remembers her father doing was creating Nano, who she knows how to modify due to her homeschooling. So, when Nano says that Professor created her, the Professor agrees, because Professor Shinonome did, not our Professor.
The Professor's real name is Kurisu MakiseAnd the world has an over 9000% divergence from Steins Gate. No, seriously. Blue eyes, red hair, scientific achievements at a young age...
The Professor is actually the DoctorShe's far more intelligent than any human has any right to be and her name can be translated as "Doctor." Logically, the Doctor regenerated as a small girl in Japan and decided to settle down for a while because, as a small girl, settling down for a while seemed like a good idea. Nano is her companion and her TARDIS is hidden somewhere in the house. To elaborate on her intelligence, she gave a cat the ability to talk. If we're being realistic (even though there's very little of that here), cats are not equipped with the circuitry to even allow the abstractions necessary for coherent conversation, meaning that she gave the cat sentience with a scarf that she built in 5 minutes. Of course, there's also the Ridculously Human Robot Nano, who she apparently made at the age of 7.
The Professor's unknown parents are actually The 10th Doctor and Rose TylerLike her father, the Professor always comes up with weird incredibly advanced machines, and she has blonde hair like mother. And though her parents have brown eyes while she herself have blue eyes, she probably inherited the blue eyes from her father's previous incarnation.
The Professor is actually Agatha HeterodyneAfter all, how many long blonde haired girls capable of building Nano at age 7 are there? They even both have officious talking cats. Perhaps she dimension-transported herself, and later returned with amnesia to become the Agatha we know. Maybe the Professor is an alternate-universe version of Agatha. Whatever, if you DNA tested the pair, you'd find a match.
That's a slightly younger Professor at the end of this xkcd strip.
The Professor (And, by extension, Nano) are employed by a weapons manufacturer.This explains how the Professor and Nano are able to live in a house on their own without any apparent employment or adults, nor Professor going to school. The Professor is obviously a child prodigy who developed a robot on her own, and a robotics company tuned in and scooped her up, giving her and Nano the funding needed to live on their own. They are the ones urging Professor to give Nano those "alterations" and, with complete data on how they work, figure out how to implement them in their own robots(Developed from Nano's design) for more sinister purposes. The gun(though airsoft) in particular is a glaring stab at this idea.
This is your Haruhi on drugs.Any questions?
The Professor was originally intended to be one of the Schoolgirls.Take a look at the Nichijou's main page pic, which is of the manga's first volume cover, and you'll see a strawberry blond, blue-eyed girl who stands out from the rest. The only character in the series with that same hair and eye combination is the Professor. This lends itself to one of two possibilities. The first, noted above, is that Keiichi Arawi originally intended to make the Professor a teenager instead of a child, but changed gears somewhere between conception and publishing to make it the Professor's robot Nano.
The blue-eyed girl on the first volume cover is an early version of YuukoThe second theory noted above. The character with the blue eyes was the original design for Yuuko and, again, Arawi changed gears before proper publication and instead gave that design to the Professor.
Sasahara knows about Tachibana's crushSasahara is actually Genre Savvy enough to notice Tachibana's tsundere attitude, and he's also aware her attacks are non-lethal. He just trolls her into embarrassment because it amuses him.
Professor is an orphan/has absentee parents/got emancipated (she does have a Ph.D. after all) and deliberately created Nano as a nanny/replacement parentThis would solve the dilemma I noted in the Headscratchers page: why is Nano "in charge" when the Professor built her?
Yuuko didn't get the words wrong when she witnessed the principal's deer-wrestlingShe wasn't trying to say "The principal is dead" but "The principal is DEATH INCARNATE".
Professor is a child of Helen Narbon Sr.Professor is the child of Helen Sr. and some Japanese dude. This one pregnancy was enough for Helen Sr. and she decided to clone herself to have children to study the genetic causes of mad science on. In the future, Professor will go mad, remove the restraining bolt/key from her gynoid Nano, give her deadly weapons, a will to fight, recruit Okabe Rintarou and his Future Gadget Lab (he surely wouldn't resist the chance to work with a real mad scientist and become her apprentice. Kuris-tina would become their agent and sexy female minion of Okabe. EVERY mad scientist needs a sexy minion. Professor's will be Nano, after a few upgrades) and take over Japan.
Professor has split personalityOne, visible to the viewers, is that of a eight-year-old child; another, which only manifests off-screen, is the "true" prodigy responsible for the Professor's engineering and scientific achievements. That would explain a lot about Shinonome Laboratories: the "genius" personality must be the one who acquires funds to sponsor Shinonome household's daily expences, procures spare parts for Nano etc; she has apparently built the robo-sister Nano to look after her childish alter-ego in the (permanent?) absence of parents.
Nichijou is a prequel to FLCLThink about it.
