Sometime after the confrontation with Cosmo Entelecheia and successfully locating his parents, [[{{Negima}} Negi Springfield]] decides that he needs some time away from Mahora to properly plan his life out, freed as he is from the need to worry about the fates of his family and students. Thus, he leaves in the middle of the night, accompanied only by Chamo, for a new school in an entirely different part of Japan. Here, he hopes to settle down for a ''normal'' year of teaching to think things through.

There's just one problem:

He's gone to [[MagicalGirlLyricalNanoha Uminari City]], three very powerful mages are part of his new class, and the TSAB is finally figuring out that maybe Nanoha and Hayate ''aren't'' the only mages of note on the planet.

What follows is a saga of equal parts sugary, fluffy goodness, mind-rape, and ensuing hilarity. All the while, a new enemy slowly encroaches on the city, threatening both Negi and his students. Considering that three of his charges include Nanoha, Fate, and Hayate, however, things are going to get very sticky, very quickly.

The story can be read [[http://www.fanfiction.net/s/6691878/1/Equal_and_Opposite_Attraction here]].

!!This story provides examples of:

* AccidentalPervert: Negi continues this fine tradition, much to his chagrin.
* AccidentalPublicConfession: Chamo, excited to see Konoka, starts talking in front of Amy...who is unaware that Negi is a mage, that Kamo can talk, and that there is a mage population on Earth. Seconds later, Asuna jumps through the window in full armor, swinging a sword around and demanding to know where Negi is.
* AdaptationalBadass: In this story, Yukihiro Ayaka has a combat-oriented artifact and is being trained by Setsuna (as opposed to being LockedOutOfTheLoop or [[spoiler: having a useful but noncombat oriented artifact]]).
* TheAloner: Negi isn't aware of the other mages in town, and unlike in Mahora, he manages to keep the fact that he uses magic (mostly) secret; as such, the local mages have no reason to inform him of anything. And since the enemy/enemies have yet to reveal themselves, he can't just call Ala Alba over for the weekend to quickly stomp them (since all the other members of Ala Alba are still in school, and can't afford to camp out in Uminari City indefinitely). As far as he knows, he is TheOnlyOne that can fend off the mysterious attackers hiding within the city. This is what leads to him resuming his training, and is why he continues it despite the increasingly dangerous weather conditions.
* AlienNonInterferenceClause: A "Prime Directive" is mentioned, and since the author has "Jean-Lauc Picard" hanging about in TSAB service, one may make some reasonable assumptions...
* AlternateTimeline: This story takes place in a world where Negi found his parents, who are happily living in Ostia (as opposed to finding out that his father Nagi [[spoiler: was serving as the latest body for the Lifemaker]]), and where Negi never [[spoiler: stopped teaching]].
* AndNowForSomethingCompletelyDifferent: In a meta example, someone else ghostwrites Chapter 13 as a part of the All Purpose Negima Fanfiction Thread's shenanigans.
* AscendedExtra: After being shadowed and downplayed in A's, Alyssa and Suzuka appear to have a much larger role in the story.
** As of the latest chapter, they're getting magic lessons from Negi.
* BigDamnHeroes: Coupled with a rousing BadassBoast [[spoiler:and ETERNAL NEGI FEVER]].
* BadassAdorable: Negi is able to destroy a small, fabricated dimension of darkness, yet Lindy, Arf, and Nanoha still succumb to his shota-cuteness.
* BadassBoast: Negi, during his [[spoiler:rescue of Hayate.]]
-->'''Negi''': I am Negi Springfield, offspring of the Thousand Master and the Princess of Ostia. I have been trained by the greatest masters of combat and magic, and have never failed to impress them. I have faced demons, madmen, cyborgs, and gods themselves, all for the sake of others. I have traveled the world in search of one man thought dead. ''And I found him.'' You think the darkness scares me? You think I am just some child? You think I would back away from anyone who would ''hurt my students?'' '''''JUST WHO THE HELL DO YOU THINK I AM?'''''
** Later, Nanoha makes one against Negi:
-->"I have fought demons, monsters, robots, and summons, I have faced down the darkest depths and rescued my precious ones from its grasp. There is no obstacle I cannot surpass, no foe I that can outrun my shot. I am Takamachi Nanoha, [[spoiler:[[SuspiciouslySpecificDenial AND I AM NOT]] [[NoseBleed A PERVERT!]]]]"
*** Damn you, puberty!
* BrokenMasquerade: Originally, the TSAB did not know about Earth's mage population. Now they do.
* CallBack: Asuna uses the example of Negi vanishing her bear panties to justify the publishing of a pamphlet about getting ClothingDamage during mage fights.
* TheCameo: The girls of TenchiMuyo all work as maids in Alyssa's employ.
** Apparently Lindy was in basic training with [[Series/StarTrekTheNextGeneration Captain Picard]].
*** Picard later shows up. Yes, he's the captain of a ship called ''Enterprise''. He even has a Data with him.
** A recipient of a Midoriya cake delivery ended up being the Marui girls from Mitsudomoe.
* TheCavalryArrivesLate: Negi, having just saved [[spoiler: Hayate]] from the mysterious darkness wielding opponents, is trying to figure out how to transport her back home when Zafira arrives.
* CoolAndUnusualPunishment: [[MamaBear Arika's]] punishment of Kurt Godel for attempting to harm Negi. Stripped of all his personal power and demoted to being Arika's secretary his office and personal quarters are relocated to next door to Arika's personal quarters. His paperwork is charmed so it can only be read at night and the wall between Kurt and Arika's rooms is deliberatly thin so he can hear everything that goes on at night. And to top it off, if he attempts to [[ADateWithRosiePalms relieve himself]]...
--> "JACK RAKAN RIGHT HAND PUNCH OF COCKBLOCKING!"
* ClothingDamage: {{Subverted}}. Nanoha and company's school uniforms have such long skirts that Negi can't blow them up with a sneeze. {{Lampshaded}} in a later chapter when Negi finds that his students have made a pamphlet explaining all the ways a mage can 'expose' you.
* ComedicSociopathy: Negi very nearly found himself on the receiving end of some after Nanoha found out that he had collapsed with a fever inside his locked apartment.
-->'''Nanoha''': "Hang on, Negi-sensei. You won't be alone anymore. Divine Bus-"
-->'''Amy''': "Nanoha-chan, what do you think you're doing?"
* TheComicallySerious: Signum
* ContinuityNod: During one of the many [[LampshadeHanging lampshade hangings]] of Nanoha's extensive usage of DefeatMeansFriendship, Alyssa points out that Nanoha has beaten up her, Fate, the Wolkenritter, and Hayate prior to befriending them.
** Shamal also has one, saying that her magic won't make Hayate walk, only her courage will. Negi promptly sneezes in response.
** Alyssa and Suzuka mention a garden party crashed by the TokyoMewMew.
* CovertPervert: Due to some mixed-up feelings about Negi, Nanoha has several fantasies about the two of them being a 'couple.'
* CrazyPrepared: The Ala Alba didn't seem to have much faith that Negi could keep his secret safe, so the Library Club published a series of pamphlets. Their topics range from dark magic possession and talking familiars to Pactio makeout tips and the risk of getting [[TooMuchInformation stripped naked while in battle]].
** Apparently, Chamo always has a few flash-bangs on hand.
* CripplingOverspecialization: In Chapter 23, Negi cannot bring himself to attack a monster just outside a window because he says none of his good attacks will leave the building intact
* CrossOver: With MagicalGirlLyricalNanoha, naturally.
** Chao and Hakase are implied to have helped [[TokyoMewMew Ryou Shirogane]] with the Mew Project.
*** Also, Alyssa and Suzuka apparently know one of them.
** [[VideoGame/TheWorldEndsWithYou Joshua]] likes drinking coffee with Fate (Averruncus).
** In Chapter 26, [[TokyoMewMew Zakuro Fujiwara]] is shown singing on a talkshow with [[VideoGame/{{Persona4}} Rise Kujikawa]]
* CrossoverShip: [[spoiler:Nanoha seems to be slowly [[HotForTeacher falling for Negi]].]][[invoked]]
* CuddleBug: Konoka's mother has a tendency to hug people when she meets them for the first time.
* DeadpanSnarker: Signum. She lampshades everyone's actions with the same direct language she uses in the heat of combat, and it's one of the funniest parts of the story.
* DefeatMeansFriendship: Alyssa calls Nanoha out on this when Nanoha notes that Negi "looks lonely", but it was PlayedForLaughs.
* DistressCall: The plot of Chapter 7.
* DynamicEntry: Nanoha attempts to use Raising Heart to bust Negi's apartment door down. Asuna has TWO: One when she kicked her door down, and another when she flies in through Fate's window. Neither are met with approval.
* EffortlessAmazonianLift: One of the first tings Konoka's mother does when she first arrives is lift both of Nanoha's siblings and father in the air in a series of spine-snapping hugs
* FacePalm: Lindy's favorite reaction to Fate-chan and Arf's antics.
* FantasticDrug: The magic chocolates.
* FiveManBand: The girls who go to Uminari to help Negi:
** TheHero: Asuna,
** TheLancer: Ayaka
** TheSmartGuy: Nodoka, relatively speaking
** TheBigGuy: Setsuna
** TheChick: Konoka
* FollowTheLeader: Zephyr-Fiction, the author, freely admits that this story is based off of ShadowCrystalMage's similar fic ''Overlords and Overkill''. However, this is PlayedWith because he and Zephyr not only have routine correspondence about their stories, but Mage has also freely accepted the fact that he inspired Zephyr in the first place.
* {{Foreshadowing}}: Fate's skin is icy cold when Admiral Graham meets her in the hallway, even though the ship itself is quite warm.
* FriendToAllChildren: Zafira, as usual. WordOfGod says this was the reason why he didn't start a fight with Negi back in Chapter 7
* FuroScene: Chapter 9 has Negi bonding with Hayate, Signum, and Vita in the bathtub, much to his embarrassment.
* GenreSavvy: {{Lampshaded}}. Chamo is fully aware that trouble will follow Negi wherever he goes. He also knows that at the first sign of trouble, Negi will wear himself to the bone with extra training.
** Nagi is aware that Jack Rakan will be far more effective than the group of palace guards Arika wanted to send for Negi's protection.
* GondorCallsForAid:
** At the end of Chapter [[spoiler:6]], [[spoiler:Hayate]], thoroughly {{mind rape}}d and isolated in a magically sealed dimension, makes a desperate telepathic plea for help. [[spoiler:Negi's]] listening, and his answer does not disappoint.
** In Chapter 12, [[spoiler: Asuna, Konoka, Nodoka, Setsuna and Ayaka travel to Uminari to help Negi when over-training puts him out of commission.]]
* HeroicBSOD: Asuna. The only difference is that she's ''not'' happy about Negi walking out on her and the class.
* HeroicRROD: Negi's morning training in dangerous conditions catches up to him, and nearly results in him succumbing to Magia Erebea.
* HeroicComedicSociopath: Nanoha's friends seem to think she's one.
-->'''Alyssa''': Oh no you don't.
-->'''Nanoha''': I don't what?
-->'''Alyssa''': You are ''not'' blowing him up just to make friends with him.
-->'''Nanoha''': I, I don't do that!
* HighSpeedMissileDodge: Used by Setsuna during a mock battle.
* IdiotBall: Negi apparently packed it away when he moved out of Asuna's room. What do you do when an unknown enemy is preying on your students and mind-raping them beyond belief? Nearly kill yourself training solo in order to protect them.
* IWorkAlone: Negi ditched all his allies and is working alone because he doesn't want to bother them. He's also worried that if he lets them know where he is, all of 3-A will come harass him again.
* KansasCityShuffle: Meta-version. In one early chapter, we all think Negi's going to sneeze and blow Nanoha and company's skirts up, as usual. Instead, he [[spoiler: propels himself into the air and faceplants onto the floor behind him.]]
* LampshadeHanging: Several regarding Nanoha's past use of DefeatMeansFriendship.
--> '''Nanoha''': W-why does everyone think I beat up my friends all the time?
* LargeHam: Asuna runs around with her artifact out, screaming about how she's going to handle Negi. Surpsingly, Konoka gets in on the act in Chapter 17.
** Ayaka and Nodoka get a scene where Ayaka goes back to her old self and provokes Nodoka into using her artifact as a blunt weapon. Vita and Hayate treat it as if they are watching a Soap Opera.
* MagicAIsMagicA: Extensive detail is given to Shamal's medical magic, along with a good explanation as to why she can't just heal Hayate's legs. Apparently, because her leg muscles haven't been used at ALL, they need to heal naturally.
* MeaningfulName: The name of the most feared and bloodthirsty admiral in the TSAB apparently means "Blood Fist" in German, or Ancient Belkan, if you want to be exact.
* MegaCrossover: Originally just between Nanoha and Negima. Now includes JackieChanAdventures, {{Persona}}, StarTrek, TenhiMuyo, TokyoMewMew and most likely more to come.
* MindRape: Poor, poor [[spoiler:Arf and Hayate.]] This seems to be the standard modus operandi of the bad guys.
** They also try it on [[spoiler:Chamo and Negi]], but both of them see through it almost immediately.
* MissingMom: We see the tail end of this trope in the form of Konoeko Konoe, Konoka's mother who has returned from a TEN YEAR trip to America.
* MomentKiller: Nagi interrupts his OWN bout of love-making to call Jack, and Arika weaponized the trope in the form of [[spoiler: a Rakan construct that punches Kurt in the face every time he tries to jerk off.]]
* MoodWhiplash:
** Chapter 4.
** Chapter 6 begins with a description of Hayate making breakfast for her knights, in which HilarityEnsues when she "punishes" Vita. It ends with [[spoiler: Hayate being {{Mind Rape}}d into thinking her knights are dead and the city is destroyed. Also contains a ShoutOut to Disney/TheLionKing.]]
* MutualMasquerade: In the beginning, the TSAB go out of their way to conceal their traces while trying to study Earth. In contrast, the Earth mages are so good at covering their tracks that the TSAB don't even know they're there. This gets broken, first by Chamo and Arf, and later by some of the Ala Alba girls.
* NotSoStoic: Signum [[spoiler: keeps herself awake all night while Hayate recovers from her MindRape.]]
* OhCrapThereAreFanficsOfUs: Lampshaded by Chisame in an Omake, after reading a chat that insinuates [[spoiler: Chisame X [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle]].]]
* OhNoNotAgain: Negi's reaction to learning that there are three mages in his new class.
* TheOnlyOne: Negi thinks he's TheOnlyOne who can handle whatever attacked Hayate, nevermind that Ala Alba would jump through hoops blindfolded to help him out if he needed it.
* OnlySaneMan: Lindy. She's the only one shown not to descend into the main cast's usual wacky antics.
* OutOfCharacterMoment: Nanoha comes off as much more uncertain at the prospect of a potential fight than she ever was in the original series.
* PutOnABus: Chrono and Yuuno are unceremoniously shipped out to New York City in order to study Earth mages. To date, they've been mentioned only three times. [[spoiler: And then they go missing after an attack.]]
** The side story ''Parallel Invesigations'' they are expected to be main characters along with the [[{{NCIS}} Gibbs's Team]], [[JackieChanAdventures Section 13]], and several OCs.
* PuttingAHandOverHisMouth: Nodoka uses this to stop Konoka from explaining about Pactios.
* SecretKeeper: Arf acted as this to Chamo regarding Negi's mage status, Chamo being capable of speech, and of the existence of mages on Earth, until Chamo finally blew his cover (On purpose, mind you).
* ShoutOut:
** Chapter 6, [[spoiler:Hayate has just been mind raped into seeing everything she loves die. Her cries for help are the same ones Simba from Disney/TheLionKing shout, word-for-word, after Mufasa dies.]]
** A far less depressing one happens in the next chapter when Negi [[spoiler: channels his inner [[TengenToppaGurrenLagann Kamina]] during the aforementioned BigDamnHeroes moment]]
** [[Series/StarTrekTheNextGeneration Data]] tries to greet the girls with the [[WesternAnimation/TransformersTheMovie Universal Greeting]].
* SneezeCut: Used almost as commonly as GondorCallsForAid. To list several:
** One breaks the fourth wall when Alyssa {{Lampshades}} the absurdity of having a ten-year-old boy teaching school. This results in KenAkamatsu having to stall the next release of the manga.
** When Shamal says that Hayate's courage is stronger than her magic, Negi sneezes, and Ayaka implies that [[CuteMute Zazie sneezed as well]].
* StealthHiBye: Albireo does this to Negi over his phone when the group decides to sit down for some "Albiero Fried Chicken"
* TakenForGranite: When the villains attempt to MindRape Negi, they show him everyone he knows having been petrified.
* TakeThat: In Chapter 23, it's shown that the Library Club used to pick apart books, anime, and cartoons for inaccuracies in their magic systems. ''Literature/InheritanceCycle'' is said to have one of the worst.
* TeamDad: Chamo for Negi. Surprisingly, he's the lone voice of reason, trying to talk the poor kid out of exhausting himself trying to protect everyone. Again...
* TeamMom: Lindy effectively turns Negi into her surrogate son while Chrono is off hunting mages in America.
** Ayaka claims she's one as well, [[InformedAbility but it has yet to be proven.]] Meanwhile, Shamal is slowly improving her cooking skills, and Signum's cover story introduces her as one for the rest of the knights.
* TheCorruption: The Magia Erebea is this for Negi. Succumbing to it is probably the thing he fears most.
** There also seems to be a large amount of 'Dark Magic' around Uminari City which seems to be attributing to this phenomenon
* TheReasonYouSuckSpeech: Yue's speech to Negi drips of this.
* TrainingFromHell: Negi does it again. It comes to bite him in the ass. '''Hard.'''
* WarriorTherapist: Signum, surprisingly. She delivers a good YouAreBetterThanYouThinkYouAre speech to [[spoiler: Hayate, the morning after her MindRape.]] While she doesn't do this DURING the battle, her reputation AS a warrior certainly gives her the title.
* WhamEpisode: [[spoiler: Yuuno and Chrono have been attacked in New York and the Asura can't do a thing about it]]
** [[spoiler: The side story has [[{{NCIS}} Team Gibbs]], [[JackieChanAdventures Section 13, along with Uncle and Tohru]] among others investigating the cause and perpetrators.]]
* WhatHappenedToTheMouse: how Negi planned to fix the Mundus Magicus problem is never addressed.
* WhatIsThisThingYouCallLove: [[spoiler:Nanoha seems to be having some problems with this.]]
* WhatCouldHaveBeen: An In-universe example: Chamo's original plan for revealing Earth magic to the TSAB involved bringing everyone to Mahorafest. Any fan of MahouSenseiNegima knows that would have been a recipe for disaster.
* WhatTheHellHero: Yue calls Negi out at length for abandoning 3-A.
* TheWorldIsJustAwesome: The view of Earth in Chapter 19.
* YouAreNotAlone: It's officially the author's favorite trope. Invoked verbatim by Signum to [[spoiler: Hayate after her MindRape]] and by [[spoiler:Negi when he rescues her from said Mind Rape.]]
