'''M×0''' ''(Emu Times Zero)'' is about a [[HotBlooded hot-tempered]] boy named Taiga Kuzumi who has failed the entrance exam to Seinagi Private High School. With [[LaserGuidedAmnesia little memory of what had actually happened]], he sets out to confront the girl who had burst out laughing at him during his interview, sure that she is to blame, only to be mistaken by a teacher for trying to sneak ''out'' instead of ''in''. Turns out that Seinagi is actually a WizardingSchool, and due to a complicated chain of events ending in said teacher being blown up, now everyone believes him to be an elite magic user--[[StrangerInAStrangeSchool when he can't use magic at all]]!

Now Taiga has to put his wits to the test in order to keep up that cover, or both he and the teacher will be in very big trouble.

!This manga provides examples of:
* AccidentalPervert:
** Taiga many times, but the one that stand out the most is him trying to protect the girls from the other boys using magic to peep. [[SarcasmMode Surprisingly]] he was caught trying to help and punished by the females.
** A little bit later after the student body knows him a bit better he expects to be punished for somehow ending up in the girls only swim time, but they just laugh and say it's OK because they know he didn't mean anything bad. It probably didn't hurt that he just saved around half a dozen girls from drowning, though.
* ActionGirl:
** Kuzumi Kokuha; every appearance has her kicking somebody's ass--usually Taiga's, and someone else's, too
** Mikuni, Hiragi's friend, unlike most other girls, uses direct physical fighting methods.
* AllLoveIsUnrequited: Mizuki likes Taiga, but he is blind to her affections. [[BloodKnight Koishikawa]] likes Mizuki, but she disliked him even before she started to crush on Taiga. [[CuteMonsterGirl Lucy]] has a thing for Taiga, but he can't even fathom loving her or Mizuki because he is crazy for Hiragi. Who also has a thing for him. [[spoiler:And then the series ends without settling any of the romantic subplots.]]
* AntiMagic: Taiga eventually trades in his fake magic card for one whose sole ability is to use up the points stored on it to create an anti-magic field. After sufficient training, Taiga is able to control the field's size, shape, and location around him.
* AwesomenessByAnalysis: Taiga manages to defeat several powerful mages by seeing their power and using their own limitations against them. During the Class matches he defeats two people, defeated one forced the other to retreat, only taking one injury because he knew exactly how to work around their power after seeing it once before, and he only used some twigs and two rocks.
* BadassNormal: Taiga's older, shorter sister Kokuha. She makes Taiga look positively weak.
* BadassBoast: Taiga uses this to avoid fights, and get out of performing magic in class. It has a decent success rate.
--> '''Taiga:''' "What is this? Your level isn't high enough for me to use magic. Since this is nothing, how about you go away and we can do this some other time?"
--> '''(Taiga's thoughts):''' ''Please do so!''
* BarbieDollAnatomy: Lucy the rest keep their clothes on.
* BatmanGambit:
** Taiga uses a few of these along with his bluffs to get by. He would pretty much be Batman, except he uses leaves, sticks and rocks instead of state of the art gadgets.
** The school principal is hinted to have some sort of gambit going on by making Taiga keep his MO instead of normal magic, but that is never resolved.
* BetaCouple: [[LightningBruiser Tsugawa]] and [[ClassRepresentative Megane]]: their classmates cannot forgive their happiness.
* BerserkButton: Call Taiga's sister Kokuha "little". [[SchmuckBait I dare you. ]]
* TheBerserker: Koishikawa keeps running straight at a problem with more magic bullets. He knows it's a bad strategy but it's the one [[BloodKnight he likes.]]
* BigEater: Karusone Natsuko as seen in the Cultural Festival arc. [[spoiler: Taiga only beats her at eating magically enlarged food by shrinking it in his mouth with M0.]]
* BigGuyLittleGuy: Koishikawa and Daimon
* BlatantLies: Taiga's modus operandi for why he does not use magic. His most common excuse is that he believes should only be used in an emergency.
* BloodKnight: Koishikawa and Ise. Ise gets better after having a fight with [[WarriorTherapist Taiga]].
* BoobsOfSteel: Mikuni at least for their class.
* BromanticFoil: Ise Kaoru.
* ButtMonkey: Because his whole class thinks that Taiga is invincible because of his magic skill, they use him to test out new spells and anything dangerous. It prompts him to hide from them a few times.
* CannotSpitItOut: Taiga to Hiragi and vice versa. Mizuki to Taiga.
** Actually, Hiragi was about to at one point, but then her dad showed up.

* ClarkKenting: A large part of the drama is Taiga trying to keep his reputation intact.
* ClingyJealousGirl: Lucy has shades of this.

* DeusExitMachina: Lucy is continently absent during the Cultural festival when they were dealing with the bomb threat. Her Mandrake Network and her ability to inform the teachers in a completely anonymous way would have made things a lot easier for Taiga and team. Taiga [[LampshadeHanging lampshades]] this.
* DistantFinale: Quite abruptly.
* DoesNotLikeMen: Mizuki says this but she really only seems to dislike her {{stalker with a crush}}. [[{{Tsundere}} Also there is no way that she at all in any way likes Taiga!]]

* EveryoneCanSeeIt: Everyone knows that Taiga and Hiragi love each other except them...

* FakeUltimateHero: Taiga. Everybody thinks he has a Gold Plate and is capable of destroying the Home Ec room with one spell and defeating a teacher. Of course, he can't use magic period and has to bullshit everything.

Otoya, the previous principal and examiner, told him he could revive Lucy but it would cost him passing the exam. Taiga accepts the deal instantly. Turns out Lucy would be just fine. [[SecretTestOfCharacter Otoya only wanted to see how Taiga would react and if he would forget that others had helped him to this point.]]]]
* GagBoobs: As stated above, Tokita Mako.
* GangOfBullies: Taiga beats up one absent mindedly, beats one up to take out his frustration, and got kicked out of his first school for defeating another. Kid does not like bullies.

* GoodOldFisticuffs: Taiga's only form of offense.
* GoodWithNumbers:
** Hiragi shows this talent during the cultural festival. When solving a rather large logic and math puzzle game.
** Then Daimon does the puzzle even faster with a bored look on his face.

* HardWorkHardlyWorks: Averted. Taiga has to bust his ass and wits to keep up the illusion of being a genius wizard, as he has no magical skill at all.

* InspectorJavert: Vice-Principal Kagami despises any rule-breaker regardless of mitigating reasons.

* LovableCoward: Taiga in many aspects, he does everything he can to get out of an actual fight so that he can stay in one piece and keep his reputation. He can and will fight when he has too, but bluffing, running, and letting his classmates fight for him are his favorite tactics. This only applies to magic fights, any other threat he is the first person running in the most dangerous direction.
* LovableSexManiac: Ise Kaoru. Not to the girls in the school at least. They hate him.
* LovePotion: Proving that he was under the influence of one is how Taiga and Mizuki become acquainted.
* MadeOfIron: Taiga goes though the meat grinder pretty much every magical competition because he is sent though the most dangerous and difficult parts, and he has no magic, but he always manages to keep right on going no matter how damaged he gets.
* MasterOfIllusion: Hiragi's is a rare heroic example. Although ''master'' is debatable.

** [[spoiler:[[SpiritAdvisor Otoya Hanasaki,]] the previous principal, Otome's father, and the only one who can create Black Plates.]]
* OneLiner: Hilariously parodied with Taiga, who's forced to come up with increasingly sappy repartees to cover up for his lack of magical talent. Of course, the excuses never fail to impress his audience.
* OurGhostsAreDifferent: [[spoiler:Otoya Hanasaki]] possesses Taiga's body while the later is working on an upgrade of his plate. While Taiga cannot use magic, the ghost possessing him still has access to his magic he had in life. HilarityEnsues
* ParentalAbandonment: The only person we ever see in Taiga's family is his abusive older sister Kokuha. Do they never question why he come home beaten up from school just about every day?

* PeoplePuppets: One of Michiyo Inui's powers.
* {{Pixellation}}: Parodied in that a special juice was splashed around which causes the object splashed to appear pixellated, often leading to many counts of its NotWhatItLooksLike.
* PowerLevels: The strength of a mage can be judged fairly well by the color of their plate. The strongest levels are Gold, Ruthenium, and likely Platinum. [[http://en.wikipedia.org/wiki/M%C3%970#Magic_plates A full list can be found on the other wiki.]]

* RoaringRampageOfRevenge: Taiga had one between the [[http://www.mangafox.com/manga/mx0/c002/20.html first and second chapter.]] A student at his old school was being bullied, so he [[KnightTemplar attacked 12 upper classmen in retaliation.]] It's also why he was even able to switch into Seinagi.
** He also had one after Daimon insulted and attacked Hiragi in the Class Matches. He used MO for the first and only time that match because of it.
* SecretKeeper:
** Eventually Mizuki and Hiragi learn of Lucy. They had been wondering why he said that name so much when he was alone...

** Lucy is a SecretKeeper of many of Taiga's secrets.
* ShoutOut: Niigaki-sensei's smoke magic refers to ''SuperMarioBros''
* SmartPeoplePlayChess:
** In the Principal's office, we have seen Principal Hanasaki playing against Hiragi-sensei. Hiragi-sensie almost always won.
** In the Cultural Festival Arc, [[spoiler: bombs have been planted around the campus and the bomber says the Magic Executive Committee must win against his people to get hints to where the bombs are located. One of the challenges is playing shogi. Hiragi, as she is Kuzumi's assistant, plays this challenge. She not only beats Daimon but thinks he' the bomber's ally, he doesn't even realize her next opponent is the one she has to look for and so [[CurbStompBattle plays him without any hesitation.]]]]
