History Fanfic / TheMoonsFlashPrincess

* OurElvesAreDifferent: Elves on Aincrad are a subspecies of human (scientific name: Homo dryadalis), with the Faeries (scientific name: Nerida magiea) of Alfheim taking the role of elves and being a completely separate species. Albeit, one that has been willingly genetically modified from their archaic ancestors thirty thousand years in the story's past to be genetically compatible with humans due to having reached a population bottleneck where the population was dangerously close to becoming unsustainably low.

* AscendedFanon: A reader suggested the nickname "Zomberyl" for Queen Beryl. Soon enough, it became canon.

''The Moon's Flash Princess'' is a ''Anime/SwordArtOnline''/''Anime/SailorMoon'' fanfiction series {{Crossover}} that posits the potential of what could happen if the ''Sword Art Online'' game was created in a world where the Senshi fight daily to keep the evil Dark Kingdom at bay.

* AdaptationDyeJob: Rather than looking almost identical to Usagi, Minako is pretty much an older and fitter Asuna, [[JustifiedTrope as befitting of her duty as the double of Princess Serenity and her reincarnation]].

* ArtificialIntelligence: Cardinal, Yui and Strea, like in canon.

* BadassAdorable: Silica, of course. Made more so since she was recruited into the DDA by Lind and learning their own brand of [[CombatPragmatist fighting]].

* BareFistedMonk: Boxy, if he has to fight, prefers to fight without a weapon in his hands, despite carrying a mace on his person, due to the fact that none of the weapons he's tried ever felt right in his hands.

* BerserkButton: Kirito's is players in SAO killing other players even though they have been warned that it would kill them in real life. Of course, there's also threatening Asuna.

* ClapYourHandsIfYouBelieve: {{Inverted}}. Kayaba's warning about players dying in RealLife if they died in the game was fundamental to ''prevent'' said deaths from happening. This is because the virus that caused SAO to become a Death Game had such a loophole.

* CombatPragmatist: Kirito has no problem with attacking opponents from behind, as shown by him killing [[spoiler:Kunzite and Jadeite]] in this manner.

* CunningLinguist: Rameses and Kebechet are fluent in three languages (Graelic, Alvarin and Lunarian) even before they come to Earth, having both learned Lunarian due to it being the Lingua Franca of the Silver Millennium and having taught each other their own native languages when they were kids. Both are working on adding Japanese to that list.

* DangerousForbiddenTechnique: Rameses knows one and is ordered by Asuna to never use it again when he does [[spoiler:against Mistress 9]] and nearly kills himself in the process.

* TheDreaded: Jadeite is this for the whole of Minato Ward, to the point that [[spoiler:his death causes ward-wide celebrations]].

* EarlyBirdCameo: Kyouji Shinkawa (Shino's friend from the ''Gun Gale Online'' arc), appears during the SAO incident in the Youma attack on the Dicey Cafe.

* GunsAreWorthless: Played with. Most firearms on Earth really ''are'' worthless against Youma, and the ones that might work have too much a risk of causing collateral damage in the process. Silver Millennium-Era firearms, on the other hand, are effective against weaker Youma, but aren't used due to the fact that there is only one available, and its owner is not going to give it up to anyone who is not specifically trained in its use for their [[UsefulNotes/GunSafety their own safety and the safety of others]].

* HappilyAdopted: Yui and Strea are adopted by Kirito and Asuna.

* HeroicSacrifice: [[spoiler:Princess Serenity killed herself to screw with the Dark Kingdom's plans.]]

* MegaNeko: Sabercats, which are a breed of cat that is descended from Aincrad's Sabertigers, with small adults being about the size of a fully grown Maine Coon. They are also highly intelligent and are notably loyal to any humans they have bonded with and live longer than domestic cats do.
** Ēkate, a Sabercat-domestic cat mix, has been called a small tiger and is at least thirteen years old, given that Kirito adopted him (or he adopted Kirito) when he was still being raised by his parents.

* OhCrap: Persephone, as Sailor Saturn, tends to bring this reaction out by those who know what she's capable of.

* PastLifeMemories: The reincarnated characters have memories of their past life. Some of them adapt better than the others - for example, during the Tenth Floor (a reconstruction of the Moon during the times of the Silver Empire), Asuna struggles to keep Serenity's memories from overwhelming her.

* ShipTease: Kirito and Asuna from pretty much the beginning.

* SideBet: Multiple characters join in a bet on when Kirito and Asuna will get married.

* SparedByTheAdaptation: Merida, who died before the Mother's Rosario arc of SAO, has her tumor treated and healed by Persephone. Yuuki and her sister, who had AIDS in canon, have it reduced to "merely" HIV and research is being done to see if they can be cured before resorting to Persephone simply eliminating their disease ''and'' their immune systems to rebuild the latter from the ground up later.

* LanguageBarrier: Subverted with Rameses and Kebechet due to several characters, usually Silica, knowing Lunarian and able to communicate with and translate for them until they can learn Japanese.

* ItsOkayIfItsYou: The only person allowed to call Asuna "Asuna-hime" or "Princess" (to her face, at least) is Kirito.

* AdaptationalHeroism: Kayaba is a good guy in the story and created SAO and ALO to train people up to assist the Senshi.

** At one point Minako got a phone call from a friend from abroad, namely [[spoiler:[[WesternAnimation/MiraculousLadybug Lila Rossi]]. Thankfully, a number of omake imply she never TookALevelInJerkass as a teen, and instead [[TookALevelInKindness became nicer]]]].

* WeWillWearArmorInTheFuture: Asuna, as many of her soldiers as possible, and the Silver Millennium survivors wear armor when in combat.

* ThereAreNoTherapists: In the aftermath of being freed, Akihiko organizes an attempt to bring in therapists to take care of the SAO survivors mental health. Unfortunately, most of them have either already formed their own opinions on the survivors or plan to put them through a medical regime that will prevent them from being able to act normally.

** Umi, despite being only ten, killed a Youma without using weapons or active magic. Granted, she's [[HalfHumanHybrid Half-Spriggan and Half-Youma]], which helped.

* ''Book 2: Waltz of the Unseelie Court'' (Ongoing): Aincrad's Final Boss has been defeated, and the Sword Art Online veterans have earned their freedom - save for three hundred players who mysteriously remain connected. Now, the veterans, their allies and their leaders, Princess Asuna and Commander Kirito, look for the reasons why their three hundred companions remain asleep while they prepare themselves for the war against humanity's greatest enemy.

** Minako is known to be fluent in French and English alongside Japanese due growing up abroad, and may know other languages.

* WorfHadTheFlu: The Sailor Soldiers are nowhere near their best due the stress of the decade-long fight against the Dark Kingdom.

* HeelFaceTurn: Several Youma have turned their backs on the Dark Kingdom.
** HeelFaithTurn: One of them, Boxy, got ordained as a Catholic priest. Grandpa Hino is a Shinto Priest.

* AdaptationDyeJob: Rather than looking almost identical to Usagi, Minako is pretty much an older Asuna, [[JustifiedTrope as befitting of her duty as the double of Princess Serenity and her reincarnation]].

* DamselInDistress: Played with in Silica's case, as she had broken free of her first prison and was well on the way to [[DamselOutOfDistress finishing her escape]] and had evaded Sugou's assistants when she was recaptured.

* {{Irony}}: Sugou chose the names Oberon and Titania for his and Asuna's avatars in Alfheim. When the real Oberon and Titania appear... they are the chief of security and the cook.

* WhamLine: In Chapter 33 of Waltz of the Unseelie Court, Kirito captures one of the D.D. Girls due to suspicions he has about her identity and after Titania finishes a scan of Kirito, Heathcliff, and the Youma:

* WhamLine: In Chapter 33 of Waltz of the Unseelie Court, Kirito captures one of the D.D. Girls due to suspicions about her identity and after Titania finishes a scan of Kirito, Heathcliff, and the Youma:

--> '''Titania:''' The results are in, and [[Spoiler: yes… this Youma is, or at least was, your mother.]]

** {{Zigzagged}} with the Senshi: after Asuna's first transformation modified their outfits based on her own they all found themselves in armor, but before that most were unarmored, the exception being Mars' full suit of armor and and Venus' armored pauldrons-something of a pet peeve for Venus, as she would have wanted more armor from the start.

* CuteKitten: Thalia, a sabercat kitten and is the only remaining kitten from Queen Serenity's last litter.[[note]]Turning into a sabercat and having had litters is a known kink of hers.[[/note]] She also likes to be in Kirito's [[HeadPet hair]] and does a good job at it, despite her silver fur.

* DueToTheDead: Boxy and Rei are brought on the expedition to the Moon, specifically to properly lay the dead there to rest. This is important, as the chapter with the expedition shows that not all the dead
