->In the year 2061, a team of elite Strategic Military Service pilots from the SVF-118 Mobius Squadron performed a test on an experimental new fold engine. In the resulting accident, they found themselves stranded in an alternate universe with seemingly no way to return home.

->It is once again the early twentieth century, and mankind is embroiled in a war against an unstoppable alien foe. They are outnumbered, outgunned and pushed to the very edge of extinction.

->But this time, there is no hope.

->In this world, the enemy cannot be reasoned with, the thought process of the enemy too alien to even comprehend or communicate with. In this world, mutual understanding cannot be found even among the disparate factions of humanity. In this world, the sky, and all the freedoms and possibilities it promises, is seemingly forevermore denied to man.

->This travesty, above all others, is the one that the four wings of Mobius Squadron will not accept.

''Muv-Luv: Do You Remember Luv?'' (aka ''Muv-Luv: DYRL'') is a series of interconnected fanfics written by Sasahara17, a crossover between Anime/MacrossFrontier and VisualNovel/MuvLuvAlternative. The general thrust of the story is this: during a field test of a new fold booster, four pilots of SMS' Mobius Squadron are flung from their home universe into the world of VisualNovel/MuvLuvAlternative, arriving just before [[LightNovel/MuvLuvAlternativeTotalEclipse Total Eclipse]] begins. Alone and cut off from their home verse, they do their best to survive and reunite, and to bring hope to a shattered world.

The first story, ''[[http://www.fanfiction.net/s/8919734/1/Muv-Luv-DYRL-Try-Again Try Again]]'', opens just after the Kamchatka arc, with newly-promoted Captain Takamura Yui announcing the new direction of the XFJ Plan: To reclaim the skies for mankind, by introducing a new type of weapon. Officials call it the [[TransformingMecha Variable Tactical Fighter]]. The pilots call it the Valkyrie. And as she makes her speech to the world, SMS Lieutenant Yuuya Bridges, callsign Mobius One, takes to the skies to dance, and to plan for when the four wings of Mobius Squadron will be reunited.

Several months later, ''[[http://www.fanfiction.net/s/9002368/1/Muv-Luv-DYRL-Valkyries Valkyries]]'' follows IJA Cadet Sendou Yuzuka, as she prepares for the last day of pre-graduation training excercises, and runs into a interesting TSF mechanic by the name of Hibiki Tatsunami. But there are other forces at work, and Yuzuka finds herself in the middle of a web of intrigue focused on Hibiki.

And moving the setting forward by over a year and a half, ''[[http://www.fanfiction.net/s/9309460/1/Muv-Luv-DYRL-Journey-Home Journey Home]]'' follows four of 207B's alumni, as they meet again after their paths have wildly diverged.

While the setting does feature mecha, it's mostly window dressing to the real focus of the story: the interaction of characters with completely different worldviews, and the culture clash between the despair of MuvLuv and the hope of Macross.

!!Tropes included in this fic include:

* AcePilot: Yuuya and his team, which consisted of Ilfried von Feulner, Lilia Kjellburg, and Hibiki Tatsunami.[[note]] All of whom are protagonists of their own Alternative Chronicles: Ilfried is the main of Euro Front, Lilia's perspective experiences The Day After 0, and Hibiki is the hero of The Day After.[[/note]]
* AlternateUniverse: The crossover has led to a number of major divergences from Alternative, particularly the [[GivingRadioToTheRomans tech inlfux]]. For example, by 2003, the F-35 Joint Strike TSF program has been revamped and is now in EMD phase, the F-23A Black Widow is in initial low rate production, the Shiranui Niigata is the Type-'''02''', being deployed in 2002, two years earlier than canon, and Boeing never makes the F-15SE Silent Eagle.
* ArcWords: ''"I am one who flew on the wings of the Valkyries."''
** Valkyrie also keeps popping up, for A-01, Project Valkyries, the nickname of the [=VTF=]s, and as the VF-12 Valkyrja.
* BiggerStick: The whole point of Project Valkyrie is to do this, by introducing gamechanging new technologies (that are reverse engineered from Yuuya's VF-19A). The VF-19A itself is a unique case; it's almost 15 years old, has been ridden hard, and is outdated compared to the VF-25 Messiah or the VF-27 Lucifer, but is still decades ahead of anything on Earth.
* BreakingTheFellowship: the A-01 Valkyries all go their separate ways after a terrorist incident at Yokohama. Yuuko, Akane, Michiru and Mitsuki are presumed dead, and Marimo returns to the IJA. Class 207B likewise splinters: by 2003, Chizuru is a Captain in the IRG, Kei is an IJA battalion commander, Mikoto is an intelligence agent, Tama-chan is a Project Valkyrie test pilot, and Meiya is an [=ISAF=] [=VTF=] mechanic.
* BreakTheCutie: Hibiki suffers from this due to his time at a mental asylum. Not only was he subjected to be told his previous life was all in his head but he's also is disgusted with the xenophobia and racism by the Imperial Japanese forces.
* {{Codename}}: All the Mobius pilots seen have their own personal callsigns. Yuuya is [[VideoGame/AceCombatZeroTheBelkanWar Cipher]], Hibiki is [[VideoGame/AceCombat5TheUnsungWar Blaze]], and Ilfried is [[Franchise/{{Dragnet}} Friday]].
* ColonelBadass: Surprising everyone who knew her, Ayamine Kei becomes this.
* CoolPlane: The Valkyries, all of them, from the VF-8 Crusader II to the VF-171EX Nightmare Plus to the VF-19A.
* DidntThinkThisThrough: [[spoiler:Akane realize her mistake when apart from the fact Yuzuka is friends with Akira whose is Michiru younger sister, she has nothing else to convince Yuzuka to help her get Hibiki.]]
* DroppedABridgeOnHim: [[spoiler: The Japanese Shogun, Kobuin Yuuhi, is apparently killed in 2002 by Alfred Walken.]]
* DrowningMySorrows: Has so far happened twice, played for laughs each time.
* DynamicEntry: Ilfried's preferred modus operandi. Nothing like bouncing a castle at Mach One in afterburner. This causes Hibiki to worry when she makes a quiet, no-fuss landing: [[OOCIsSeriousBusiness Illfriede doesn't make normal landings.]]
* EasyLogistics: Discussed and mostly averted for the Valkyries. Yuuya's VF-19 runs out of ammo very quickly, and can only make a few sorties before lack of spares grounds it permanently; Lillia Kjellberg runs out of ammo in short order, and the F-15OT Over Eagle that Vincent designs has [[MoreDakka a lot of guns pilots love]] and ammo consumption logistics personnel hate.
* {{Expy}}: The VF-8 Crusader II is essentially this to the VF-0 from Anime/MacrossZero, with some modifications.
* [[GivingRadioToTheRomans Giving Valkyries to Alternative Earth]]: Yuuya and his backseater, Shinsei Industries engineer Vincent Lowell, decide to help Alternative Earth tech up as much as possible, by reverse engineering the technologies in their VF-19A. As a result of this, the XFJ Plan, [[LightNovel/MuvLuvAlternativeTotalEclipse originally conceived to develop a new TSF for Japan]], is reborn as Project Valkyrie, an R&D project to develop new warfighting technologies (though it's less developing, and more reverse-engineering technologies from Yuuya's VF-19, and adapting them to the limitations of Alternative Earth). Among their early successes include making the EML-99X railgun a more practical weapon and developing prototype Valkyries based off the VF-0.
* ForWantOfANail: Yuuya Bridges being an SMS Valkyrie pilot instead of a US Army [=TSF=] pilot changes quite a few things, particularly the Kamchatka arc: [[spoiler: Ibrahim was piloting the 94 Second Phase 1 testbed, and died at the forward base, covering Yui's retreat; Natassja Ivanova was shanghaied by Yuuya to be his backseater in the VF-19A, with them eliminating the Lasers, so she survives Zhar's elimination; Leon Kuze's Raptor is stolen during the RLF Incident; Sagiri's battalion and the Fuji School Brigade receive railguns and the coup happens in 2002.]]
* FragileSpeedster: The VF-8 Crusader and the EF-2002 Dragoon Variable Tactical Fighters. In-universe [[http://www.fanfiction.net/s/9162721/1/ Evaluation]] notes that they hold significant advantages over conventional [=TSFs=], but lack the ammunition capacity for prolonged firefights and rely on hit and run attacks.
* InsistentTerminology: It's not a Variable Tactical Fighter, it's a Valkyrie.
** While in Japan, Hibiki writes his name in Western order (first name, last name) instead of Japanese (last name, first name).
** Roy Focker refers to the ''John F. Kennedy'' as a boat and is corrected by Claudia La Salle; "boat" is for small boats and submarines, a carrier is a "ship."
* InterserviceRivalry: Humorously shown in "Anchors Aweigh", the first sidestory in the snippet collection, where US Navy Commander Roy Focker leads Skull Flight and their Crusaders on a MissionFromGod: to defeat the US Army's Infinities and their Raptors. [[spoiler: Both groups are later found [[DrowningMySorrows sharing the same bar]], thanks to the Marines in their Crusaders winning Blue Flag 02.]]
** More seriously, ''Journey Home'' shows that the Imperial Royal Guard has succeeded in marginalizing the Imperial Japanese Army, to the point where the [[LightNovel/MuvLuvAlternativeTotalEclipse Type-02 Shiranui Niigata]] is an IRG machine, with the IJA forced to make do with the near-obsolete Type-94 Shiranui and Type-89 Kagerou.
* MarshmallowHell: Makabe Seijuro is subjected to this by Illfried. He just calmly rolls with it.
* MoreDakka: Vincent Lowell manages to build an F-15 variant with up to six assault cannons for even more dakka.
* NegatedMomentOfAwesome: Yuuya pulled off a fantastic one-man airshow, with multiple vapour trail drawings in the sky in ''Try Again''. Unfortunately, everybody was captured by Yui's RousingSpeech and so missed the airshow.
* NegativeSpaceWedgie: Occurred during testing of a new fold booster. It transferred Yuuya and his flight into the Alternative world, and apparently swapped them with their Alternative counterparts. What happen to their Alternative counterparts is never explained.
* NoodleIncident: Due to the InMediaRes format and the timeskips, a number of these occur, such as the details behind Project Valkyrie's move to Dover from Alaska, what ''really'' happened during the Red Shift incident, Makabe getting the Golden Kite with Illfriede's help, and so on.
* OhCrap: Akane gets this reaction, [[spoiler: when Yuzuka decides to bring Alternative IV and Project Valkyrie together]].
* PoorCommunicationKills: In ''Valkyries'', [[spoiler: Suzumiya Akane and Natassja Ivanova come to a confrontation because their parent organisations have no idea what each other is doing and instantly assume they're out to get them and steal Hibiki. It ends badly for Akane.]]
** To clarify, [[spoiler:Project Valkyrie believes Alternative IV are part of Allegiance due to the latter being a top secret group they have never heard before and Alternative IV believes Project Valkyrie are part of Alternative V due to their supporters redirecting Alternative IV funding to Project Valkyrie.]]
* RankUp: By 2003, Sakaki Chizuru is now a Captain in the IRG. Her rival Ayamine Kei, meanwhile, is now a Lieutenant Colonel in the IJA.
** Also, it's mentioned offhandedly that Marimo has gone from being a Sergeant in the UN Army to a Brigadier General in the IJA.
* RealityEnsues: [[spoiler:Akane is easily subdued by Natassja due the former having no experience in close human combat while the latter does.]]
* RedBaron: Yuuya picks up the sobriquet "White Knight of the Atlantic." A so far unnamed ISAF pilot has picked up the handle "[[AceCombatZeroTheBelkanWar Demon Lord]] of the Pacific."
* RightHandVersusLeftHand: In ''Valkyries'', [[spoiler: A-01 and Project Valkyrie come into contact; Yuuko suspects Project Valkyrie to be their enemies, while Project Valkyrie is mistrustful of A-01, having never heard of them before. They're both working towards the same goals. They're in a catch-22 because both parties won't trust each other unless they talk, but neither party will talk unless they trust the other. See PoorCommunicationKills above.]]
* RunningGag: Ellen Aice keeps being declared dead, and keeps showing up alive.
* ShoutOut:
** Yuuya's flight being part of [[VideoGame/AceCombat04ShatteredSkies Mobius Squadron]].
** Also, Yuuya's mentor was [[Anime/MacrossPlus Isamu Alva Dyson]].
** The fighter launch sequence in ''Journey Home'' is a shoutout to [[{{VideoGame/Battlefield3}} Going Hunting]], while the AWACS callsign is [[AceCombatXSkiesOfDeception Crux]].
** In ''Journey Home'', the UN has established a new special task force called [[VideoGame/AceCombat04ShatteredSkies ISAF]], and Stella Bremmer is now a pilot in the [[VideoGame/AceCombatAssaultHorizon Warwolves Squadron]].
** Ayamine Kei's first command is nicknamed [[VideoGame/BattlefieldBadCompany Bad Company]].
** Illfried has a habit of wearing [[CoolShades aviators]] when she's [[Fanfic/StrikeWitchesQuest bouncing people in Dover Castle]].
** Makabe's XO is Kei Nagase of the VideoGame/AceCombat series.
* StrawmanHasAPoint: Hibiki spends most of ''Valkyries'' being disgusted with the attitudes and ethos espoused by Imperial Japan, but Natassja points out that Japan was forced to adopt such attitudes, because it was necessary for survival as a nation.
* TakeAThirdOption: Alternative IV and Project Valkyrie don't know anything about each other and mistrust each other, and their only options are either ignoring each other or opposing each other. [[spoiler: Yuzuka instead decides to try and open a dialog between both groups]].
* TimeSkip: There's a gap of about six months from ''Try Again'' to ''Valkyries'', and about a year and half to ''Journey Home''.
* WildWeasel: Mention is made during ''Try Again'' of how Yuuya took his VF-19 on a sortie to clear Laser-class BETA in Kamchatka, relying on his pin-point barrier for defense.
** By the time of ''Journey Home'' (2003), laserjagd missions are a key tasking for [=VTF=] squadrons, allowing [=TSF=]s and airpower to move freely.
* TheVerse: Apart from the main stories released, there are also some sidestories set in between the timeskips:
** ''[[http://www.fanfiction.net/s/9143871/1/Muv-Luv-DYRL-Snippet-Collection Snippet Collection]]'': A series of sidestories set around the verse, mostly humorous in nature.
** ''[[http://www.fanfiction.net/s/9162721/1/Muv-Luv-DYRL-Garuda-Wings Garuda Wings]]'': Project Valkyrie, as seen through the eyes of [=COSEAN=]'s Garuda Flight.
* VitriolicBestBuds: A mild version between Hibiki and Ilfriede, where they trade barbs, Ilfriede fills Hibiki's cockpit with Haggis, Hibiki makes an earnest attempt to kill Ilfriede (or at least brain her with a heavy wrench), but they're as close as siblings.
