Describe ''I Am Negima and So Can You'' here. Yeah, you go on and try.

The best way to describe this is what an actual crossover by Creator/StudioSHAFT would be like, rather than just lipservice/cameos.

@/{{Cygnus}}'s breakout into the ''Manga/MahouSenseiNegima'' fanfic world, but set in the ''Negima!?'' continuity. Why?

The second half is ''Anime/PaniPoniDash''. [[spoiler: a third part includes SonicTheHedgehog]]

Negi finds that his class is struggling in math thanks to a new teacher on the block.

Dean Konoe's solution? Call Rebecca Miyamoto.

But this turns into an ExcusePlot when Becky's gang follow her, leading to one of them going missing, just as the heroes also ''actually find'' the legendary chupacabra... Or is it? And thusly they become involved in something increasingly bigger than the child teachers can imagine.

As he was annoyed with the feeling TheyWastedAPerfectlyGoodPlot in ''Negima!?'' despite loving the flawed series otherwise, this author decided to railroad the Star Crystal arc [[spoiler: for a little while]] in favor of a new and more involved plot. Seriousness need not apply--it's a SHAFT work after all.

Is part of a series, divided up into Acts much like a play [[spoiler: or a Sonic level]].

* [[ Act I: Scheme!?]]
* [[ Act II: Nightmare!?]]

One last thing: Don't be fooled by one of the characters sharing a name with this troper, it is NOT a self-insert by any means.
This story provides examples of:
* AllGirlsWantBadBoys: Rokugou's attraction to Cygnus.
* AntiVillain: Cygnus, who holds many types but is primarily a NobleDemon.
* BatmanGambit: Frequently employed by Cygnus to further his plans, [[spoiler: Konoka uses one against ''him'' at the end of ''Scheme!?'' so he would waste his then barely-out-of-control powers]].
* BoundAndGagged: Poor Rokugou... Cygnus has an attack that induces this, [[spoiler: Konoka's turn might be coming soon...]]
* BossFight: Used and lampshaded in ''Nightmare!?''
* CameBackWrong: [[spoiler:Akira Ookouchi, Type 4, forced by Cygnus to prevent her from becoming a Type 2 naturally]].
* ChessMaster: Konoka, [[spoiler: Chao Lingshen]] for the good guys. Cygnus is the villain for this trope.
* DrunkOnTheDarkSide
* CrouchingMoronHiddenBadass: Himeko.
* EldritchAbomination: [[spoiler: Cygnus Cantus]].
* EnemyWithin / SplitPersonality: [[spoiler: Anti-Asuna, who isn't really evil but is something more akin to Asuna's [[KingdomHearts nobody]], and Asuna's Heartless, which is the EnemyWithin part.]]
* IAmLegion: Lirael, [[spoiler:since all the mermaids are failed clones of herself]].
* LetsGetDangerous: Most of the PPD cast
* ReluctantMonster: [[spoiler:Sonic, during most of ''Nightmare!?'']]
* ShoutOut: Just about everywhere. The entirety of ''Nightmare!?'' is a shout out to the ''Franchise/{{Castlevania}}'' franchise, certain fights play out like boss fights from certain video games, etc.
* StealthPun: Dialogue in Episode 9:
-> "What the hell is up with Lirael?!" - Becky
-> "Same thing you get when you cross an elephant with a rhino." - Asuna
* StockholmSyndrome: Rokugou and Cygnus. The other characters don't like this, fearing StockholmShnozzing. [[spoiler: ironically enough, Cyg's biggest rival Konoka does not care]].
* TomatoSurprise: The chupacabra in Act I turns to be [[spoiler: Sonic the Hedgehog, or rather Misora Kasuga masquerading as Sonic the Hedgehog, stalling for time on Chao's orders until the real Sonic can show up.]]
* WakeUpGoToSchoolSaveTheWorld: How the story begins, but averted and takes a backseat to the issues at hand.
* WithGreatPowerComesGreatInsanity: Cygnus's OneWingedAngel form, [[spoiler: Rokugou's armor card]], an inversion with Himeko's armor card, which makes her less spacy and slightly more aggressive.
