One night in 2006, a call goes out to NHK and the Tokyo police, giving notice of a suicide jumper from the then-incomplete Tokyo Sky Tower. Ordinarily, this wouldn't be ''too'' unusual, except for one small detail: Akiko Yamaguchi, the suicide jumper, is a MagicalGirl. She has fought a long, lonely war against {{Cult}}s, a CircusOfFear, and the embodiments of fear itself for years and has reached her breaking point. She transforms on live television and takes the plunge. But before she becomes a wet crimson smear on the pavement, a black-clad angel swoops in to save her - [[LyricalNanoha Fate Testarossa]], with Nanoha Takamachi flying in shortly after.

In response to the news that they ''aren't'' the only ones with magic in the world, {{Magical Girl}}s and their support groups all around Earth come out of the woodwork and close ranks. In so doing, the magic which has kept TheMasquerade in place since the fall of [[Franchise/SailorMoon the Silver Millennium]] comes unravelled and TheMagicComesBack. The people of Earth must now come to terms with the extremely magical world they live in; the enemies of Earth must contend with public knowledge of their existence; and the defenders of Earth lock arms against the encroaching darkness.

Hosted at the [=SpaceBattles=] Creative Writing Forum, it is a multi-author collaborative effort. At present the project is still mostly in the planning stages due to one author handling the entire first arc on his own, but numerous snippets of plot have been written by various authors and the thread broke the 100-page mark in just over a week. Feel free to drop by with your two cents.

[[strike:Chapter One of the First Arc, Unity, was released on October 6th, 2011 on FanFictionDotNet. [[http://www.fanfiction.net/s/7441415/1/Battle_Fantasia_Unity Link]].]] ''' ''CURRENTLY, THE FIRST ARC IS UNDERGOING A PROCESS OF REVISION AND STREAMLINING. [[TwoLinesNoWaiting ONE HALF]] OF THE NEW VERSION CAN BE READ [[http://forums.spacebattles.com/threads/the-nagasaki-heroes-battle-fantasia-project-story.239060/ HERE]].'' '''

The project has also created two {{Spinoff}}s:
* [[http://forums.spacebattles.com/showthread.php?t=185147 Lyrical Chronicles]]: Described by the Author as "The VideoGame/{{Super Robot|Wars}} Route" of Battle Fantasia. It appears to be working towards a CrisisCrossover with LyricalNanoha's [[SubspaceOrHyperspace Dimensional Sea]] as its enabler.
* [[http://forums.spacebattles.com/showthread.php?t=186588 Paved With The Best Intentions]]: An AlternateUniverse sharing the same setting as the main story, but with greater focus on ''Franchise/LyricalNanoha'' and ''Anime/PuellaMagiMadokaMagica''.
* [[http://forums.spacebattles.com/threads/girls-of-the-sorcerer-oneshot-unofficial-bfverse-madoka.235768/ Girls of the Sorcerer]], a One-Shot concerning the MGA's first confirmed brush with the Puella system.

[[http://bfp.wikia.com/wiki/BFP_Wiki Has a wiki]], for easy record keeping of ideas.

Unfortunately, as of 2013, the project seems to have collapsed due to politics and infighting among the various contributors.

As of January 2014, a group of Italian fanwriters have resurrected the project [[http://battlefantasiaita.forumfree.it/ here (Italian only, for now)]].

Not to be confused with either ''VideoGame/BattleFantasia'' or the MagicalGirl [[RealTrailerFakeMovie Real Trailer Fake Game]] movie clips from which the name is borrowed.

!!''Battle Fantasia Project'' provides examples of:

* AdultFear: Several parents have to face the fact that their daughters are Magical Girls engaged in life-or-death battles with the forces of evil. In an early version of the story, Shoutan Himei briefly undergoes a bout of PTSD when she finds out her daughter became a Puella Magi.
* AlternateUniverse: ''StrikeWitches'' and ''InfiniteStratos'' are here in spirit [[PragmaticAdaptation if not in canon]], with their characters and concepts uprooted from their original settings and replaced here in convenient places.
** To elaborate: ''StrikeWitches'' is more or less directly imported from the alternate 1940s setting it takes place in, with the Neuroi being among the numerous extradimensional invaders harassing Earth and the Striker Units being the military's attempts to subvert PoliceAreUseless via {{Magitek}}. ''InfiniteStratos'', likewise, covers life at a magic academy [[NanohaStrikerS where Nanoha is one of the top combat instructors]], with the IS units being Earth-produced devices reverse-engineered from Belkan and Mid-Childan tech.
* BreakingSpeech: One of the tools favoured by the Nightmare Factory.
* BroadStrokes: The general concepts of various series such as ''FateKaleidLinerPrismaIllya'' or ''Anime/PuellaMagiMadokaMagica'' are used, but not the full continuity baggage.
* CarFu: Akiko [[CrowningMomentOfAwesome resorts to this]] in a prequel Snip, using a cement truck and a tank of gasoline to kill a monster which is resistant to her magic. [[http://forums.spacebattles.com/showpost.php?p=5731326&postcount=1614 Observe.]]
* CatchPhrase: For the Alliance, "You are not alone". The thread itself also has the unofficial motto '''''"[[Anime/PuellaMagiMadokaMagica INCUBATOR MUST DIE!!!]]"'''''
* ClearMyName: Due in part by their [[DarkMagicalGirl Unorthodox]] [[EldritchAbomination appearences and powers]], and Akiko's reaction to them in the new version of Akiko's revelation, the majority of the cast assume that [[Franchise/BlackRockShooter Mato and the girls]] work for the Nightmare Factory.
* CombatPragmatist: Akiko, who missed a power-up due to her familiar's death and has to fight season 3 enemies with season 2 magic. She compensates by use of unorthodox tactics like CarFu and using her magic rather... ''creatively''.
* {{Deconstruction}}: Akiko's experience as a magical girl has more in common with ''SailorNothing'' and ''Anime/PuellaMagiMadokaMagica'' than with ''Franchise/SailorMoon'' or ''Anime/PrettyCure'' due to the fact that it shows how mentally scarred and traumatised one would be after fighting alone for seven years, with no support network and no PowerOfFriendship to back her up.
* DefeatMeansFriendship: Deconstructed in ''the cruelest manner possible'' by the Nightmare Factory's MindRape of Nanoha, who twisted her canon motives around and accused her of simply beating Fate until she was more scared of Nanoha than of Precia.
* DespairEventHorizon: Crossing it was what led Akiko to jump.
* DreamWithinADream: The method by which the Nightmare Factory trick Signum into revealing everything she knows about the LyricalNanoha crew.
* DrivenToSuicide: Akiko right at the start. She gets better.
* EarthIsTheCenterOfTheUniverse: Earth is drawing an unusually high amount of Dark Kingdom activity and an equally unusual number of magical girls.
* EnemyWithout: The Nightmare Factory makes a point of manufacturing these things as part of their modus operandi, but only one has any real plot significance. Unfortunately, that enemy is [[spoiler: Dark Nanoha]]. ''[[OhCrap Both of them]]''.
* HeroicBSOD: The Nightmare Factory's primary weapon.
** The Factory's success rate with this tactic tends to vary depending on how at peace their target is with themselves. The Senshi and [[Anime/BlackRockShooter Team Black Rock]], having faced their fears many times before, can NoSell them and turn the tables on their attackers with no problem. Nanoha on the other hand...
* ImmuneToBullets: Double subverted. Small arms can work against mooks, but [[MonsterOfTheWeek Monsters Of The Week]] need tank-killing or anti-structural munitions - a bad idea in UrbanWarfare - while top-tier enemies and {{Eldritch Abomination}}s require magic to hurt them at all.
* LateToTheTragedy: [[FutariWaPrettyCure Honoka and Nagisa]] were busy with diplomacy business on behalf of the Dusk Zone in some of the local sub-dimensions when TheReveal happened. They came home to find the newspapers raving about Akiko and other magical girl sightings.
** Two of the [[Franchise/SailorMoon Outer Senshi]] go to America to help a suspected Magical Girl... Well... Just look at what trope this is listed under.
* MagicalGirl: OF COURSE!
* TheMagicComesBack: Not that it ever really left to begin with, it's just not hidden anymore.
* ManipulativeBastard: [[Anime/PuellaMagiMadokaMagica Kyubey]]. Moreso than in the original series, because the existence of [[Franchise/SailorMoon the Galaxy Cauldron]] means that the heat death of the universe is ''impossible'' and the Incubators have ''other'' purposes in mind for all that energy they're gathering.
* TheMasquerade: Deconstructed. Yes, fighting in secret helps to protect your identity and your family from your enemies, but it also hides you from potential allies.
* MegaCrossover: Far too many series to list them all exhaustively, but for a quick sample of some of the core series:
** Anime/BlackRockShooter (OVA and using elements from a [[RecursiveFanfiction fanmade]] TabletopGame)
** Manga/CardcaptorSakura
** FateKaleidLinerPrismaIllya
** LightNovel/{{Kampfer}}
** LyricalNanoha
** Anime/{{Mai-HiME}} and Anime/{{Mai-Otome}}
** Anime/PrettyCure
** PrettySammy
** Anime/PuellaMagiMadokaMagica
** RoninWarriors
** Franchise/SailorMoon
** SailorNothing
** Franchise/GIJoe
* MercyKill: One of the reasons Akiko is so messed up. When she was ten she had to beat her best friend to death with a barbell. She was transformed by the Circus into one of their monsters.
* MultinationalTeam
* NoodleIncident: Akiko's tenure as a MagicalGirl will largely be this. Not because the authors can't come up with anything horrifying enough, [[SerialEscalation but because they can, and they can't dial it back]].
* NoSell: High-level monsters and eldritch abominations can do this to all mundane weapons regardless of how much 'boom' they have due to the [[{{Slayers}} mazoku-like]] quality of having their true forms hidden away in the astral plane, where only magic can reach them and hurt them.
* OCStandIn: The ''Anime/BlackRockShooter'' cast includes a few characters that weren't in the OVA, with [[OriginalCharacter associated real-selves]].
* OriginalGeneration: Since the vast majority of all magical girls reside in Japan, a host of original characters (of [[SturgeonsLaw varying]] quality) has sprung up to fill out the international community. Few of these characters are involved with the core plot, save for Akiko and the Nightmare Factory.
* PoliceAreUseless: Played with. Because of the way the project uses the ImmuneToBullets trope, police and military are only effective in direct combat against low-ranking mooks. However they can still support the Alliance with training, logistics, transportation, and various other forms of support that the magical girls can't manage on their own.
* RecursiveFanfiction: The ''Anime/BlackRockShooter'' team takes elements (including terminology) from a fanmade TabletopGame based on the OVA. This was before the 2012 anime was released, [[{{Jossed}} which had it's own take on things]].
* ReverseCerebusSyndrome: Things start off very dark; suicide and weaponised mindfuck are not things that come up in the usual MagicalGirl work. The work will eventually move to less grim pastures.
** In the meantime, several snippets set during the current arc help to balance this out a bit, especially the ones featuring the Kampfers and PrettySammy. Turns out that weaponized love and happiness is Super Effective against creatures made of nightmare fuel, and the Kampfers introduce a healthy dose of comedy, especially through [[GenderBender Natsuru's]] "[[PlayedForLaughs nightmare]]" of [[http://forums.spacebattles.com/showpost.php?p=5791226&postcount=4146 becoming a pregnant housewife]] at some point in his future.
* SharedUniverse
* StealthHiBye: Gamlain's take on [[Franchise/SailorMoon Tuxedo Mask]] is fond of using this trick.
* TalkToTheFist: Deconstructed. Using violence to [[ShutUpHannibal get Hannibal to Shut Up]] rather than beating him through reason won't help clear the seeds of doubt he planted. Furthermore, if the Lecturer's main thrust was that you're a trigger-happy belligerent, why, you're not doing yourself any favours, dear [[spoiler: Nanoha]].
** Also played straight in the case of Strength and the rest of the Anime/BlackRockShooter girls, though, who've already dealt with most of their issues in advance and can completely NoSell the Nightmare Factory's attempts to BreakingSpeech them.
* TokyoIsTheCenterOfTheUniverse: Japan has an unusually high number of magical girls.
* TookALevelInBadass: The Senshi are pegged somewhere in between their anime incarnations and their "love and justice-powered eldritch abomination" manga versions, while Tuxedo Mask has been dubbed Batman!Mamoru for his awesome usage of the StealthHiBye. [[PrettySammy Sammy]] is also slated to get a power-up from Tsunami to make her powers more suited for fighting evil, while Ayeka and Ryoko have inherited powers vaguely similar to those that their TenchiMuyo counterparts possess.
* ATragedyOfImpulsiveness: Lindy ''told'' them not to charge into uncharted enemy territory. [[spoiler:Didn't she Nanoha and Signum? Akiko faced these guys for ''four years'' and it results in her attempting to commit suicide? Did you ''really'' think you could wipe them out in one hit?]]
* TwoLinesNoWaiting: The new version of Arc I will be split in two: One plot focusing on Akiko and a number of magical girls in Tokyo, and the second will focus on the [[Franchise/BlackRockShooter Black Paradoxes]] helping out a newly discovered team in Nagasaki.
* TheUnmasquedWorld: The premise.
* WeakButSkilled: The Nightmare Factory is no match for high-powered girls like Nanoha and Signum in terms of pure firepower, but they make themselves a threat by using psychological warfare. Akiko herself, having missed quite a few powerups due to her familiar's early passing, has also had to fight in... unorthodox manners.
* WorldOfBadass: It's been observed by some that this version of Earth is basically the TSAB's version of [[TabletopGame/{{Warhammer 40000}} Cadia]], having been under siege by demonic and extradimensional forces since ''at least'' the fall of the Silver Millennium 10,000+ years ago.
* WoundedGazelleGambit: [[Anime/BlackRockShooter Strength]] uses this on one of the Nightmare Factory's minions, pretending to break down and have a HeroicBSOD in the face of a BreakingSpeech, then turning around and [[WrestlerInAllOfUs suplexing]] the minion for a OneHitKill when it takes the bait.
* YouAreNotAlone: The very core of the whole story.
