[[caption-width-right:298:The King of Knights vs. The Emperor of Thieves! Who will win?]]

''Just an Unorthodox Thief'' is a ''LightNovel/FateZero'' and ''[[Franchise/LupinIII Lupin The Third]]'' crossover by Creator/TheInfamousMan. Yes, the same author behind ''Fanfic/FateZeroSense'' and ''Fanfic/ADifferentKindOfTruth''. It uses the familiar concept of someone summoning a Servant from another series...this time, Kirei Kotomine has accidentally summoned Lupin The Third as Assassin. How will this affect the Fourth Grail War? Read it [[http://www.fanfiction.net/s/8868025/1/Just-An-Unorthodox-Thief here]], and find out.

For those unfamiliar with the ''Fate'' franchise, seven Heroic Spirits are summoned from the Throne of Heroes, a resting place residing [[TheLifestream outside of time and space]] that is reserved for those brave men and women whose deeds have become legends, and are now venerated as eternal guardians of mankind, to fight as Servants in the Holy Grail War. However, being a "hero" isn't strictly required, as some of the summoners discover in this story. This means that for Lupin to have become a Servant, he's been dead... For ten years. Most of the Lupin cast members have been forced to move on after his death. Some have handled it better than others, whereas some still long for the glory days when their friend/enemy/rival was among the living.

For those unfamiliar with the ''Lupin'' franchise, Lupin the 3rd is the grandson of the original GentlemanThief, titular Frenchman ''Literature/ArseneLupin''. Lupin Sr was intelligent, fast, and powerful enough to rival Sherlock Holmes. The grandson is less classy, but even more dangerous. He is normally accompanied by three friends, but this work downplays their influence. He is, however, still chased by a policeman who has dedicated his life to tracking down Lupin, and has collected an impressive arrest record by catching the criminals Lupin has competed with. Criminals like the mages Lupin has been summoned to fight. With the power that comes from being a "Heroic Spirit", Lupin seems to be getting even more incredible.

!!This fic has examples of:
* AbnormalAmmo: Lupin frequently uses ammunition for his weapons that has unique properties, such as exploding bullets and glue rockets.
* AbortedArc: Berserker's true identity as [[spoiler: Lancelot]] goes uncommented upon as he [[spoiler: dies fighting Archer before Saber finds out who he really is.]]
* AbsurdlySharpBlade: All the Servants' weapons, and also Goemon's Zantetsuken.
* ActuallyPrettyFunny: Kireiís general opinion of Lupinís antics.
* AdaptationalBadass: Risei, who in this story is Tokiomi's SmartBall-holding HypercompetentSidekick.
* AintTooProudToBeg:
** Kariya begs Assassin to kidnap Sakura from Zouken, because of the physical and mental torture Sakura is facing.
** Kirei begs his father, Risei, to give Sakura treatment and protection after he and Assassin kidnap her from Zouken.
* AlwaysGetsHisMan: Zenigata, with the exception of Lupin and his gang, always catches the criminals he chases.
* AnachronismStew: During Kiritsugu's flashback [[spoiler: to when he first met Lupin]], it is mentioned that he and Natalia have two Jeircho 941 handguns and a Calico M950 among their weaponry for the job. These two weapons were not available during the time the flashback takes place (1976).
* AndThenWhat: Zenigata had no idea what to do after Lupin's death. Supported by Lupin canon.
* AntagonistInMourning: The Heroic variety. Zenigata eventually lost his drive to catch criminals after Lupin's death, leading to his retirement. Also happens in Lupin canon.
* AntiHero: Assassin may be a straight-up thief but he's too noble to be a VillainProtagonist. Though, he does have a bit more ruthlessness than his "lighter" self from the second anime series.
* AppealToAudacity: This is how Lupin convinces Jigen that he's telling the truth about magic. It also helps that the gang went through all sorts of supernatural shenanigans during their time together.
* ArchEnemy: Archer '''HATES''' Assassin because he stole some of his treasures/Noble Phantasms. Assassin is the only person Archer is actually motivated to kill.
* ArmorPiercingQuestion: When Assassin questions Kirei about his not being upset at seeing Caster's sadism, he asks how Kirei would feel if Caster had captured his daughter. This question makes Kirei so angry that he ''orders'' Assassin to shut up.
* AscendedExtra:
** Daisuke Akimi from ''LightNovel/KaraNoKyoukai''. In canon he just existed to give Mikiya leads. Here he's Zenigeta's [[TheLancer lancer]] and [[NumberTwo right-hand man]] and is a competent detective in his own right.
** Risei gets in on the act as well. He steps into the plot a lot more as his faith in Tokiomi wanes and he decides to more discreetly back Kirei and Assassin while growing into a three-dimensional character.
* AssassinOutclassin: A flashback shows how Kiritsugu met Lupin III when the latter was still alive: Kiritsugu and Natalia had been hired to kill the Edelfelt head, and Lupin didn't want a murder happening on his watch. [[CaptainObvious Not only did the hit fail]], but [[OvershadowedByAwesome Kiritsugu realized how outclassed he was by Lupin and his gang]] even before Goemon [[ImplausibleFencingPowers cut down]] [[MonumentalDamage the Golden Gate Bridge]] to stop Kiritsugu and a few dozens police cruisers from giving chase.
* AwesomenessByAnalysis:
** Assassin's power set is built around this. His EX-Rank ''Eye For Art'' allows him to identify a Noble Phantasm (and from that, the identity of the Servant using it) just by looking at it for a few seconds. In addition to that, his A-Rank ''Discernment of the Poor'' allows him to psychoanalyze anyone instantly, allowing him to know their mental strengths and weaknesses.
** Lancer, as well: he is able to figure out Assassin's tricks and Noble Phantasms after only seeing them once. Of course, Assassin has many, many, ''many'' more tricks and tools at his disposal.
** Zenigata is another example. He figures out that Lupin/Assassin is inside the sewers thanks to a cigarette butt that was put out outside the entrance. The cigarettes are Gitanes, a brand from France and Lupin's favorite brand, and who else other than Lupin would smoke cigarettes imported from France in Japan?
* BadLiar: Tokiomi is certainly this after his second interview with Zenigata and Daisuke. On everything from Sakura to his connection to the Einzberns and Matous, he fails to provide a decent explanation or excuse.
* BashBrothers: Kirei and Assassin finally become this when they work together [[spoiler: to kill Zouken]] in the Fifthteenth Heist.
* BackToBackBadasses:
** Invoked by Saber with Assassin versus Caster's little tentacle monsters.
** Saber and Zenigata versus the Owls of Minerva's Kuken.
* BadassDriver:
** Kirei becomes one when he becomes Assassin's getaway driver.
** Jigen displays his incredible driving skills when fleeing from mobsters.
* BadassGrandpa: Zenigata may be past sixty, but that just shows how damn good he is since he can ''still'' compete with the new and improved, superhuman Lupin. The same could be said about a now-aged Jigen and Goemon.
* BadassNormal: Zenigata and Jigen. How badass? Zenigata is still able to chase Lupin and Jigen [[spoiler:KILLS GILGAMESH!]]
* BadassPreacher: Kirei and Risei.
* BandagedFace: [[spoiler:Pycal]] has one.
* BeatStillMyHeart: Caster does this during his tirade about Assassin in the Fifth Heist. To add insult to injury, thanks to Caster's magic the poor child is ''still'' alive.
* BerserkButton:
** Assassin normally has NervesOfSteel and refuses to let anything get to him, but a few things are shown to make him genuinely angry:
*** Caster, in a case of EveryoneHasStandards.
*** Assassin also deems Zouken to be such a monster, so he gets more serious, wears his green jacket, and makes his fight with Zouken [[ItsPersonal personal]].
*** People disrespecting [[WorthyOpponent Zenigata]].
** Zenigata surprisingly has one: Lupin being accused of crimes that do not fit his M.O. Lupin may be a thief, but he's not a sociopath in Zenigata's eyes.
* BiggerBad: Count Luis Yu Almeida. He's been dead for years but his atrocities still cast a shadow over many characters and have set many tragedies into motion.
* BigBadEnsemble: Currently the two biggest antagonistic forces are split between Assassin's opponents in the Holy Grail War and [[TheSyndicate the Owls of Minerva]].
* BigBadWannabe: In the end, this is all [[spoiler: Zouken]] is. When he goes up against someone who can actually fight back against his tyrannical abuse he folds like wet cardboard.
* BigDamnHeroes:
** Berserker intercepts Archer before he can kill Assassin during the docks battle.
** Just before that, Rider saves a Gae Buidhe-less [[SpannerInTheWorks (Assassin stole it)]] Lancer from being cut down by Saber.
* BlackHumor: Assassin dabs in this from time to time.
-->'''Assassin''': ''[After explaining how he burned Caster's book using a portable flame thrower]'' So when I give someone the finger, you know I mean it!
* BodyHorror: The Kuken are not a pretty sight with their outfits torn off.
* BoomHeadshot:
** How [[spoiler:Lancer]] kicks the bucket.
** Lupin tries to do this to [[spoiler:Zouken]], but it doesn't stick.
** [[spoiler:The almighty Gilgamesh]] is killed this way. [[DeathByIrony With bullets made of]] [[spoiler:[[DeathByIrony Lancer's stolen weapon]]]][[DeathByIrony , no less]].
* BoundAndGagged: [[spoiler: Sola-Ui]] suffers this thanks to Lupin.
* BrainwashedAndCrazy: The Kuken oh so much.
* BrokenMasquerade: Tokiomi is convinced that Lupinís calling card giveaway at the end of the Second Heist has caused this. Risei calms him down by stating that A) as Lupin has been confirmed dead for over a decade, the public would probably think it's the work of a copycat and B) the Grail War has been so well guarded that most {{Muggles}} wouldn't realize the significance of its mention.
* TheBully: As Assassin points out, this is all Zouken is at the end of the day. [[spoiler: This is why he's a BigBadWannabe.]]
* ByronicHero: Kiritsugu as always. But an entire chapter aptly titled "The Killer Called Kiritsugu" is dedicated to showing how broken Kiritsugu is inside.
* CameBackStrong: Lupin, of course.
* TheCameo:
** First is Daisuke Akimi, a mundane cop from ''LightNovel/KaraNoKyoukai''. He's more of a CanonImmigrant now because of The Nasuverse, and due to becoming a regular supporting character as Zenigata's partner.
** Then there's Mayu (and company) from ''Manga/ElfenLied''. Goemon retired from thieving and became a bushido instructor in Kamakura, watching over Mayu in particular as a surrogate father. WordOfGod said this was done purely as a ShoutOut to the series.
** Riko Mine, AKA Lupin the IV, from ''LightNovel/AriaTheScarletAmmo''. [[spoiler: She was conceived the night before Lupin's death.]]
** And of course, we can't forget [[spoiler: Shirou, who gives Zenigata the lead he needs to track down Ryuunosuke.]]
** Taiga's grandfather is mentioned as one of Lupin's contacts.
* TheCavalryArrivesLate: Zenigata and the police show up just in time to arrest [[spoiler: Ryuunosuke]], AFTER [[spoiler: Lupin and Saber have killed Caster]]. In this case, it's lucky they did arrive late, otherwise they would have been slaughtered by Caster.
* TheCasanova: Lupin LOVES the ladies, and can charm almost anyone with the right lines, the only exceptions being Fujiko and Saber. (Though, he doesn't really try with Saber due to the fact that her body does not suit his tastes.)
* CassandraTruth: Lupin DID tell Zenigata that a cube confiscated from him would make the vault go boom. Zenigata refuses to believe him and tosses the cube over his shoulder...
* CatchPhrase: Goemon's "Once again, I have cut a worthless thing."
* CharacterDevelopment:
** To protect Lupin from his father, Kirei [[spoiler: claims that Lupin was acting on his orders in killing Caster. He is also surprised that he was feeling joy when he thought about sinners being punished for their crimes]].
** Lupin is revealed to have been a lot darker before teaming up with the others, softening over time.
* ChainedToABed: Fujiko Mine's parting gift to Lupin after their night together.
* ChaseFight: Jigen has a shootout with mobsters while trying to drive away to safety.
* ChekhovsGun: Remember how Lupin stole [[spoiler:Gae Buidhe]] back in chapter 5? Over twenty chapters later, it's revealed what he did with it.
* TheChessmaster:
** The leader of the Owls of Minerva, the Count, has plans for the course of the war. [[spoiler: They have tabs on the various masters and Servants, substances that can affect even Servants, and a wide net of operatives all poised to manipulate future events]]. Kiritsugu believes that Lupin is one of these as well
** Lupin. Though he feels bad about it, he delays Sakura's rescue to follow his plan. Risei actually thinks that Assassin's every flight of fancy is a carefully calculated move contributing his overall victory. It's unknown if this is true, but the Laughing Peacock heist has made Assassin too well protected for Tokiomi to order his death.
* ClapYourHandsIfYouBelieve: Lupin inspires Sakura in this way as he rescues her from Zouken.
* ClockKing: Kirei even comments on how organized and precise Lupin can be in regards to heists, assuming that Lupin isn't forced to resort to the IndyPloy.
* CombatPragmatist: Lupin of course. If he can use something to gain an advantage in a fight, he'll use it immediately with few exceptions. Some examples include attacking Masters, stealing the weapons of Servants, blinding enemies, etc. Saber even does this once [[spoiler: to bring down Caster's guard in order to kill him]]. Kiritsugu is an extreme example.
* CompositeCharacter: Lupin is this of himself. He has the manga version's {{Chessmaster}} abilities, his ''The Woman Called Fujiko Mine'' and first anime version's charisma, skill, and a bit of their ruthless side, and his Second Series version's morals... which actually makes a lot of sense, since Heroic Spirits are idealized versions of their original selves. It makes perfect sense that the Servant Assassin has all of Heroic Spirit Lupin III's best attributes.
* ContinuityNod: Various Lupin series episodes, movies, and even a bit of the original manga by Monkey Punch are mentioned throughout the fic.
* CoolCar: Lupin and Kirei's yellow Fiat 500.
** Jigen's black Nissan Skyline.
* TheCorrupter: To a minor extent, [[ManipulativeBastard Assassin]] is this to [[KnightInShiningArmor Saber]].
* CostumeCopycat: thanks to his notoriety, people have begun wearing outfits and hairstyles similar to Lupin's. Justifies his use of a PaperThinDisguise since he looks like those copying him.
* CrashIntoHello: How Lupin reunites with Fujiko Mine. [[spoiler: And also how he first meets his daughter.]]
* CrazyPrepared:
** Lupin, of course, with one of his Noble Phantasms geared towards it.
** Zenigata also counts. In the case of the Laughing Peacock, he attempts to use guards, surveillance equipment, himself, and even a tracking device to stop Lupin. He still fails, but points for effort! Humorously, we find out that he keeps a pair of handcuffs under his pillow just in case Lupin enters his bedroom!
** Maiya muses to herself about Kiritsugu's Crazy Preparedness after Kiritsugu explains Lupin's tactics for creating a body to believably fake his death and admits that if he had the resources, it's more-or-less exactly how he would do it.
* CrouchingMoronHiddenBadass: Lupin himself, as per his series.
* CrowningMusicOfAwesome: [[InvokedTrope Invoked]] [[WordOfGod by the author]]. TIM has suggested some pieces of soundtrack for specific scenes.
** ''[[https://www.youtube.com/watch?v=g4mwKjoOhQY Afro Lupin]]'' for a CarChase between Assassin and Zenigata.
** ''[[http://www.youtube.com/watch?v=j8IYmYreGWQ Wuthering Heights]]'' for a confrontation with Caster.
** ''[[https://www.youtube.com/watch?v=cRBQz-yd7-Q Super Hero]]'' for the CarChase between young Kiritsugu (TIM [[LampshadeHanging admitted the]] {{Irony}}) and Lupin.
** ''[[http://www.youtube.com/watch?v=0xL5IQVg3Yk Elegy 1]]'' as the song for when [[spoiler: Lupin dies.]]
** ''[[http://www.youtube.com/watch?v=FX2ci_vr8o4 Lupin the 3rd Theme 80]]'', the theme standard for Creator/HayaoMiyazaki's work on the franchise, for a CarChase between Lupin and the police after rescuing Sakura in Chapter 19, "Fourteenth Heist".
* CurbStompBattle: How Archer kills [[spoiler:Lancer]]. He's so [[TranquilFury serious]] about killing Assassin that he demands that [[spoiler:Lancer]] leave and kills him when he refuses, all without so much as a taunt or glance.]]
** The "Fifteenth Heist". [[spoiler:Kirei]]'s ruthless, NoHoldsBarredBeatdown of [[spoiler:Zouken]] when the latter [[spoiler:comes to the church to try and take Sakura back]]. [[spoiler:Kirei]] holds nothing back and turns [[spoiler:the elder Matou]] into little more than a bloody smear on the pavement, before [[UpToEleven completely obliterating his soul]]. Justified, in that giving him no chance to recover kept him from [[spoiler:dispersing into Crest Worms and escaping]], and completely awesome and satisfying to behold.
-->[[spoiler: '''Kirei''']]: ''Kyrie Eleison.''
* CutLexLuthorACheck: Subverted. The first thing Lupin does after stealing Archer's Noble Phantasms is sell them for extra cash.
* DareToBeBadass: Lupin does this to Kirei in an effort to get him to be true to himself and find his own place in the world outside of what others expect of him.
* DarkReprise[=/=]SoundtrackDissonance: TIM gives every major scene a song from Franchise/LupinIII, during a flashback episode a chase between Lupin and Kiritsugu TIM said that Kiritsugu's theme was a song called ''Super Hero'' which becomes this if you compare Kiritsugu and Lupin's view points. The song basically boils down to a "Lupin is Cool" song with lines like "Scream for me, a romantic modern hero" and "Everyone wishes they could be like me" it fits Lupin perfectly as he effortlessly outfoxes two of the worlds greatest assassins while saving an innocent life, but from Kiritsugu's angle it becomes a Sarcastic Echo as the lyrics mock him by basically being what he wants a Hero of Justice to be, and in a way, what he wants to be, all while basically saying that a common thief is a better superhero than he is. The song really becomes rather sad if you listen to it and make it Kiritsugu's theme, instead of Lupin's.
* DeadManWalking: Kariya admits that he is one of these thanks to the worms in his system.
* DeathByAdaptation: [[spoiler: Zouken [[NoHoldsBarredBeatdown gets]] [[HumiliationConga what]] [[CruelAndUnusualDeath he]] [[UndignifiedDeath deserves]] ten years earlier than in canon. [[CrowningMomentOfAwesome And it is ]]''[[CrowningMomentOfAwesome glorious.]]]]''
** [[spoiler: Archer doesn't escape either.]]
* DefeatByModesty: Goemon cutting off the clothes of police officers, forcing them to run away as a result.
* DestroyTheEvidence: [[spoiler: The entire mansion was rigged with incendiary explosives to prevent information from falling into enemy hands]].
* TheDevilIsALoser: While Zouken isn't Old Scratch (and doesn't have Angra Mainyu under his control) he pretty much hits all the marks showing how much of a loser he really is as Assassin and Kirei awesomely ruin his life.
* DidYouJustScamCthulhu: Assassin successfully steals ''[[WorldsStrongestMan Archer's]]'' Noble Phantasms and gets away with it. [[{{Understatement}} Archer is pissed.]]
* DidntThinkThisThrough: Zenigata takes personal satisfaction in pointing out to the bank manager that ANY sort of challenge to Lupin in regards to this thieving skills WILL be accepted.
* DidntSeeThatComing: Zouken supposedly had the perfect plan to deal with Assassin, [[spoiler: too bad he underestimated those muggle policemen.]]
** Zouken does this again by ''somehow'' forgetting about [[spoiler:Assassin's Master, Kirei the Executioner]], while talking to Assassin.
* DirtyCop: The Fuyuki Police Department Chief is one. He is paid by Tokiomi to conceal evidence of magi, transfers Byakuya Matou before he can be interrogated by Zenigata, and is overheard implying that he [[spoiler:lent SWAT vans to Russian mobsters to help them facilitate a kidnapping]].
* TheDogBitesBack: A mild version. Tohsaka treating Risei like a servant causes Risei to chew him out.
* DragonInChief: Tokiomi realizes that [[WorldsStrongestMan Archer]] is this to him and fears him becoming TheStarscream because he'll have a 100% chance of success.
* DragonWithAnAgenda: As the plot unfolds, Kirei's loyalty shifts to Assassin, wanting to help him with his goals rather than Tokiomi's.
* DressingAsTheEnemy: [[spoiler:Lupin and Saber]] steal the clothes of two SWAT officers to escape the police. However, Zenigata sees right through them. Also mixes with SpottingTheThread, as [[spoiler:Lupin's use of slang and the ill-fit of the uniform on Saber give them away to Zenigata.]]
* DroppingTheBombshell:
** Lupin outs Caster's identity during the Seventh Heist.
** Lupin takes ''great'' pleasure in the shocked looks on Jigen and Goemon's faces when he admits that he's finally managed to bed Fujiko.
* DudeWheresMyRespect: Due to constantly failing to get Lupin, Zenigata can't catch a break with his fellow cops in the Fuyuki police department. It gradually goes away thanks to his string of closed cases while working with them.
* EnemyMine: Assassin/Lupin convinces Saber to work together with him long enough to [[spoiler:kill Caster]]. [[spoiler: [[TragicHero Kariya]] also seeks him for an alliance shortly after the first one dissolved.]]
* EntertaininglyWrong: Tokiomi assumes that Riseiís wariness around Lupin is due to the fact that the latter has successfully managed to rob the Church. Itís actually because [[GenreSavvy Risei]] knows that [[ManOfWealthAndTaste Tokiomi]] is ''exactly'' the kind of guy whom Lupin loves to rob blind.
* EvilCannotComprehendGood: This is Zouken's biggest weakness. He can't see anyone but as selfish, petty, and monstrous as himself, leading to him not realizing that having a ZeroPercentApprovalRating will lead to anyone having a shred of dencency wanting him dead, rules be damned.
* EvenEvilHasStandards:
** Lupin may be a thief, but even HE hates Caster's cruelty. Kiritsugu also points out the fact that the women Lupin supposedly 'raped' (In reference to the implications in the manga that Lupin is a rapist) were simply lying to cover their own skins.
** Count Luis Yu Almeida was considered so fucked up that ''the Nazis'' kicked him out due to moral disgust.
** Jigen reflects on how Lupin in the past would use everything and everyone to win whereas Jigen, himself, could not.
* EvilIsPetty: Assassin points out that this is all Zouken is during an awesome TheReasonYouSuckSpeech. He points out underneath all of Zouken's monstrousness is a bully who can only lord his power over people weaker than him and the only reason why he does the horrible things he does is because he ''knows'' that it is all he can do other than die.
* {{Expy}}:
** The Count seems to be a callback of classic James Bond villains, as were most of the villains in the Lupin III franchise.
** The Owls of Minerva, themselves, are slight references to the Batman villains 'The Court of Owls' with some of their henchmen being similar to the Court's henchmen, the Talons.
** Daniel Gump, the man Lupin and the gang steal from during Lupin's last heist, is based off of Creator/DonaldTrump.
** The two Yakuza members at the docks in Chapter 25 are based of off Jules and Vincent from ''Film/PulpFiction''.
* ExtendedDisarming: PlayedForLaughs. Lupin has a lot of hiding places for his gadgets, and Zenigata knows most, if not all, of them, as he proves when he starts disarming an apparently caught Lupin. Among other things, Lupin's hairpiece has a lit bomb under it and one of his wrists has all the parts needed to build a small radio under the flap of fake skin.
* EyepatchAfterTimeSkip: Goemon is wearing an eyepatch when we finally see him. It later gets explained during the {{Flashback}} to the day Lupin died.
* EyeScream:
** The Kuken have their eyes held open ''ALL'' the time with hooks!
** Goemon lost his eye thanks to [[spoiler:helicopter shrapnel]] during Lupin's last heist.
* FacingTheBulletsOneLiner: [[spoiler:Kariya]] to [[spoiler:the Owls of Minerva]], after helping to kill [[spoiler:Archer]] and having OneLastSmoke.
--> ''"What are you waiting for? I don't have all day."''
* FakingTheDead: Lupin supplies fake corpses of himself and Kirei after [[spoiler:Maiya's assassination attempt]].
* FamousLastWords: Lupin's last living words.
--> ''"Hey guys...it was fun!"''
* FantasticDrug: The Owls of Minerva's Fraulein Eule has incredible hallucinogenic effects even on Servants.
* FatalFlaw:
** Kayneth's pride and Lancer's [[MyMasterRightOrWrong loyalty]]. [[spoiler:Assassin plays on this by managing to convince Kayneth to fight Tokiomi and Archer.]]
** Zouken's LackOfEmpathy and self-centeredness, along with looking down on muggle police and law. [[spoiler:Even if he ''did'' somehow take Sakura back from the Church, he'd have to go through the police to do it and [[ExactWords the geis is very specific about the terms of Sakura's adoption.]]]]
** Archer's arrogance, [[CharacterDevelopment which he seems to be cured of after two unsuccessful attempts on Assassin's life.]][[spoiler:Unfortunately, this gives him a new flaw: tunnel-vision. He's so focused on Lupin when he appears directly in his line of sight that he fails to notice a muggle sniper (Jigen) lining up a fatal shot on his head.]]
* ForWantOfANail: Lupin's presence and actions turn ''Fate/Zero'' canon upside down. New alliances and rivalries arise, Servants are defeated in different order and in different manner, static characters like Saber and Archer get actual character development, and Kirei's character takes a turn for the better.
* ForTheEvulz: One of Ryuunosuke's motives for murder.
* FriendlyEnemy: Assassin and Zenigeta's relationship is this. Saber and Kirei are baffled by the concept.
* FusionFic: In this story's continuity -- and in a major contrast to most ''Fate'' crossovers -- Lupin III was an infamous thief in the Nasuverse and all of his exploits are very well known. Some characters from ''Fate/Zero'' actually met him before his death.
* GambitPileup: Lupin and the Owls of Minerva are the main Chessmasters in this fic, though every other Master/Servant pair have plans of their own.
* GenreThrowback: Of '70s anime/manga and partially of spy thrillers like ''Franchise/JamesBond'', right down to the idealism and fun while also retaining its own sense of moral ambiguity.
* GentlemanThief: Lupin III is proud to be one.
* GoOutWithASmile: Lupin does this in a flashback to the end of his actual life.
* GoodIsNotDumb: As long as it doesn't involve Kirei, Risei is a very smart and GenreSavvy man.
* GunStripping: In Chapter 9 (Eighth Heist), Assassin is cleaning his gun while reviewing last night's heist with his Master.
* GutFeeling: How Fujiko realizes that Lupin is, well, [[BackFromTheDead Lupin.]] Which leads to this gem:
--> '''Lupin''': [[WasItAllALie Ah, was our bond really that weak guys?]] [[WomenAreWiser Fuji-cakes could tell it was me from just a feelin'!]] You had to try to kill me and then interrogate me before you knew it was me! [[WithFriendsLikeThese What kind of friends are you?]]\\
'''Jigen''': Shut up.
* HannibalLecture: Lupin gives Lancer such a good one about his blind obedience to chivalry and Saber's willingness to put her honor aside that Lancer actually has a brief HeroicBSOD.
* TheHeavy: Assassin is a rare protagonist version of this trope. Every change of the plot has been caused by him and almost every character has been reacting to his actions.
* HeroOfAnotherStory: Zenigata is this to Lupin, investigating the troubles of Fuyuki City as Lupin fights in the Grail War and they occasionally crossing paths.
* HonorBeforeReason:
** Saber takes her pride and integrity as a king and a knight seriously. However, [[spoiler:in the case of letting Caster live for another night to kill more innocent children, she decides it is necessary to let go of her honor in order to save them.]]
** Kayneth and Lancer, which ultimately leads to [[spoiler:Lancer being killed]].
* HopeSpot: [[spoiler:Lancer]] has a brief one when he [[spoiler:launches Gae Derge at Archer]].
* HowDareYouDieOnMe: Zenigata does this in a flashback when he finds out that Lupin is really dead.
* HumiliationConga: [[spoiler:Tokiomi]] goes through this, between losing his Servant [[spoiler:Archer]], getting eliminated from the Holy Grail War, [[spoiler:having all of his money stolen by Lupin]], and [[spoiler:receiving threatening phone calls from people who believe that he sold Sakura into sexual slavery to the Matous]]
* HyperspaceArsenal: Assassin's "Tools of the Trade" Noble Phantasm gives him access to ''any'' item which he requires to complete a "heist." These range from the mundane (grappling hooks) to the exotic (rockets, fake limbs) to the why-would-you-even-''have''-that? (A replica of the Laughing Peacock with its head replaced by his own, an inflatable Lupin balloon the size of a building.)
* {{Hypocrite}}: Saber condemns the Lupin III cosplayers who get plastic surgery to look more like him:
-->''Completely ignoring the life they had been given for an opportunity to be someone else? It was worse than trying to escape reality. It was obsession to an unhealthy degree.''
::She's not wrong about the cosplayers, but from ''VisualNovel/FateStayNight'' we know that this wording describes Saber's motivation for winning the Holy Grail pretty well. She wants to use the Holy Grail to erase her rule as KingArthur by choosing not to pull the sword from the stone, ignoring all the good she did as king and trying to become someone else.
* IfIWantedYouDead: Lupin tells Saber that he could have easily poisoned her drink when she wasn't looking, leading to a very painful death for her, if he were taking things seriously.
* IgnoredExpert: Risei Kotomine. To his credit, he knows better than to underestimate Asassin because Lupin stole from the Church numerous times, including the [[http://en.wikipedia.org/wiki/Papal_tiara Papal Tiara]] within a day of his calling card and escaping the Executioners guarding there. Tokiomi brushes the concerns aside, but when Assassin not only survives Archer but delivers calling cards all over Fuyuki about winning the Grail, Risei all but says, "I told you so."
* ImpaledPalm: Assassin has his hand impaled by Gae Dearg during his fight with Lancer. However, this stops a fatal blow from striking his chest.
* ImpossibleFencingSkills: Goemon can safely cut clothes off of people and can cut right through a suspension bridge.
* ImpossibleThief: Lupin is already this in canon, but as a Servant it's brought UpToEleven. Why? He can steal Noble Phantasms, including Archer's, which would normally be impossible due to his power to recall them at will (the theft blocks this power).
* ImprobableAimingSkills: Jigen displays them during the Chase Fight. Not only does he fire at the cars behind him and kill his targets almost without looking, he shoots out the bolts holding up an overhead traffic light so that it falls on one of the cars chasing him, all of this while driving at high speed.
* ImprovisedWeapon: Zenigata can use his handcuffs in many ways, including using them as bolas to catch his target.
* InadvertentEntranceCue: In the First Heist.
--> '''Lupin''': Would have expected Archer to attack by now... Maybe heís got the runs or something?\\
''[Cue Gilgamesh]''
* IndyPloy: When his original plans fail, Lupin can come up with backup ones on the spot.
* InTheBack: Two bullets in the back [[spoiler:killed Lupin during his final living heist.]]
* {{Irony}}:
** Archer, the character who in all of fiction is famous for his AesopAmnesia, is learning from his mistakes.
** Continuing with Team Tohsaka, Tokiomi is a man who prides himself in his ability to control any situation. Every member of his faction either is a DragonWithAnAgenda, is TheStarscream, or has gone behind his back in some way. This includes Risei, who in canon is Tokiomi's YesMan.
** [[DeathByIrony Of the deathly variety:]] [[spoiler:Archer DIES because he took a fight too seriously.]]
* ItOnlyWorksOnce: Lupin's ''Better Luck Next Time'' Noble Phantasm works like this. Lancer nearly kills him when he figures that out by going for the same fatal strike again.
* JustAFleshWound: Many characters show examples of this trope, some even being capable of combat despite having what most would consider mortal wounds.
* KillItWithFire:
** Lupin/Assassin's solution to Caster's regenerating Familiars.
** Assassin later tries to kill Lancer this way as well.
* KilledMidSentence: [[spoiler: Lancer.]]
* KnightOfCerebus:
** [[WouldHurtAChild Caster]] is this to the point where his very presence causes a complete ''GenreShift''!
** Zouken takes up the mantle, with him being a pathetic excuse of sub-human life and all.
** The Count and the Owls of Minerva by dint of being {{Combat Pragmatist}}s to the core.
* KnowWhenToFoldEm: Lupin is never afraid to run away from a fight. He even outright states that in a straight-up fight against opponents like Gilgamesh he would surely lose.
* LaserGuidedAmnesia: How Risei hides the Holy Grail War.
* LeeroyJenkins: Averted by Zenigata due to him being OlderAndWiser. He even lampshades his lack of this during the search of Kariya's apartment, that a younger him would have stormed in without thinking about it, warrant or not.
* LegacyCharacter: Invoked In-Universe, where the various Lupin copycats who sprang up after the original's death held a competition to see which one of them deserved to hold the title of "Lupin the Third."
* LetsGetDangerous: Assassin switches to his green jacket, showing that he's treating [[KnightOfCerebus Zouken]] as a serious threat.
* LifeOrLimbDecision: Lancer has a minor example of this where he slices at his own feet to escape being immolated by Assassin's fire chemicals, Lupin lets himself gets impaled in his hands to prevent a killing blow to his chest.
* LittleMissBadass: If anyone gets too touchy-feely with her, Taiga WILL kick their ass.
* LoveMakesYouDumb: It almost makes [[SmugSnake Kayneth]] sympathetic.
* {{Magitek}}: The Owls of Minerva have created cyborg owl familiars.
* MajorInjuryUnderreaction: [[spoiler:Zouken]]'s reaction to being [[spoiler:shot in the head]] by Assassin is to ask if it was really necessary.
* ManipulativeBastard: Don't let Assassin's charm fool you. Although he has standards, he will twist your emotions around to get what he wants if he deems it necessary. This is best shown when he manipulates [[spoiler:Saber]]'s inner goodness to make her [[spoiler:abandon her Chivalry in order to kill Caster]].
* MasterOfDisguise:
** Another of Lupin's specialties via his ''Mistaken Identity'' Noble Phantasm. [[spoiler: Neither Kayneth nor Lancer have any idea that the Sola-Ui they're speaking with is Lupin in disguise]].
** Berserker is also capable of this if his Master uses a Command Seal.
* TheMole: The police chief is this for Tohsaka, keeping him informed of possible breaches regarding Magecraft to the public.
* MoralityChain: Lupin tries to invoke Kirei's daughter as this. When Kirei's sadistic tendencies take over, Lupin usually asks Kirei what he would feel if X happened to Caren? So far, [[EvenEvilHasLovedOnes it has worked.]]
* MrExposition: [[HyperCompetentSidekick Risei]] increasingly becomes this to Tokiomi, much to his annoyance.
-->''[[LampshadeHanging Did he have to spell it out for the man?]]''
* MurderIsTheBestSolution: Kirei is ready to kill the police officer inspecting his truck if the officer sees Assassin, whom he's looking for. Fortunately, Assassin takes care of it with an optical illusion.
* NeverMyFault:
** Kayneth definitely has this attitude, constantly blaming Lancer for any and all failures.
** To a lesser extent, [[spoiler:Tokiomi]]. He refuses to believe that he caused his own downfall.
* TheNicknamer: Assassin rarely calls anyone by their actual name.
* NaziNobleman: Count Luis Yu Almeida used to be one while he was alive, but got kicked out because everyone else thought he was a sick and twisted monster.
* NoNonsenseNemesis: Archer becomes one through character development, which is rather scary considering it disables his FatalFlaw.
* NobleDemon: Assassin, a.k.a. Lupin III, is a world-renowned criminal with his own moral code, particularly concerning rape and the safety of women and children.
* NotSoAboveItAll: Daisuke gradually takes to calling the "copycat" Lupin as well, despite not believing him to be the real deal.
* NotSoDifferent:
** Kirei starts to draw a few parallels between Lupin and Kiritsugu.
** Lupin and Kirei share a lot of similarities as well, a fact which the latter takes a while to clock onto.
* NotSoStoic: With enough trauma the Kuken go absolutely insane.
* ObfuscatingStupidity:
** Lupin, despite seeming like an idiot, is actually a very skilled tactician and can use any tool to his advantage. He is also very capable of stating his intentions of killing someone with a happy grin.
** Zouken is completely aware that the Owls of Minerva are spying on him and that Assassin is targeting him.
* OffscreenMomentOfAwesome: Natalia versus Jigen during a flashback chapter.
* OldCopYoungCop: Zenigata and [[LightNovel/KaraNoKyoukai Daisuke]], respectively.
* OlderThanTheyLook: Fujiko, with Lupin commenting her to be a hot granny. Same goes for Lupin due to being summoned as Assassin.
* OneLastSmoke:
** Lupin's last request during his final moments in life.
** [[spoiler:Kariya]] also has one (Lupin gave him a cigarette and lighter earlier) before he is killed by [[spoiler:the Owls of Minerva]].
* TheOnlyOneAllowedToDefeatYou: Zenigata has this attitude towards Lupin. A mob boss has this attitude towards killing Lupin.
* OOCIsSeriousBusiness:
** Kirei freaks out a bit when he fails to understand why he's acting the way he is now. It takes an explosion at his apartment to snap him out of it.
** A more common one is when Assassin stops smirking. When he does that, all hell is about to break lose.
* OvershadowedByAwesome: Zenigata failing to catch Lupin during the Laughing Peacock heist has led to a lot of mockery and derision from the rookies/desk jocks of the Fuyuki police surrounding his inability to catch Lupin in the past. But Kirei's narration makes it clear Lupin could've made capturing him ''even more'' difficult. Lupin seems to be teaching him how to enjoy life on the edge.
* PaperThinDisguise: Lupin only wears a fake mustache and glasses outside of a police station and doesn't get arrested. Justified to himself by the fact that apparently a lot of people like to cosplay as him.
* PoliceAreUseless: Averted. Many Magi are caught blindsided with what the police can accomplish when someone competent (Zenigata) is leading them.
* PooledFunds: Lupin would sometimes literally bathe in money back in the '60s, but it's hinted that he only did this when he was high.
* PuttingTheBandBackTogether: Inspector Zenigata comes out of retirement, and later on [[TheGunslinger Jigen]], [[MasterSwordsman Goemon]], and [[FemmeFatale Fujiko]] head to Fuyuki City. [[spoiler:Subverted in the sense that Lupin's old gang has moved on since he died, with the only exceptions being Jigen, whom Lupin is getting one last favor from, and Zenigata, who is too stubborn to let Lupin go.]]
* {{Pride}}: Lupin has full knowledge that he's the greatest thief that ever lived, and doesn't mind boasting it. Though, he's usually more subtle with boasting about his skills unless he ''really'' wants to rile up someone.
* ProperlyParanoid: Zenigata proves to be this in regards to keeping quiet about evidence that he gathers during the events of the Grail War, since revealing it would result in confiscation and Memory Manipulation to hide it away.
%%* ReactionShot: The end of the Second Heist.
* TheReasonYouSuckSpeech: Lupin gives one to Lancer regarding his complete obedience to his Code of Chivalry and honor.
** That is nothing compared to the absolutely awesome one Assassin tells Zouken. Read it:
---> '''Assassin:''' All this is pointless in the end, don't you see that? Even if ya demanded to [[spoiler:have Sakura back]], it wouldn't last. Pops and the cops are lookin' for ya, and I don't think that the old man is going to completely cover for ya. If anything he will wipe their memories of any magic-related stuff and make you up to be just some sick old rapist. That alone will make them relinquish you as Sakura's legal guardian, and hunt you down to take her from you. And even if you were to avoid them and try to start fresh, the terms of the geis wouldn't hold because the stick in the mud signed off Sakura to ''Matou Zouken'', and no one else. You're disgraced and alone, so why bother tryin' to [[spoiler:get her back]]? Because of pride. [[SoreLoser Ya hate losin']], because you haven't lost in a long time have ya? You so desperately want to save this plan because you know that without Sakura or Kariya, you and your family are finished. And once your family is gone, you'll wither away and die. Face it. You're just an old, sick, and stubborn man who has lived too damn long for a goal he probably doesn't even remember. All you're doin' is torturing a child and beatin' a sick man who can't defend himself anymore. Tell me, 'cause I'm actually a little curious... what does that even accomplish?
* RetiredBadass: Zenigata... at least until his Lupin senses start tingling. Also, the rest of Lupin's old gang.
* RefugeInAudacity: All of [[MagnificentBastard Assassin's]] plans hinge on being so over-the-top that no one will believe that they would work.
* RevealingCoverup: Tokiomi's failure to convince the police causes Zenigata to get even more suspicious about the participants of the Grail War.
* RevolversAreJustBetter: Jigen's weapon of choice is a .357 Magnum.
* {{Sadist}}: In a similar vein to ''Fate/Zero'', Kotomine Kirei is a budding sadist living in denial. Unlike ''Fate/Zero'', Lupin is here to prevent Kirei from going full blown For The Evulz-mode and help him find enjoyment in (slightly more) moral ways. See SmitingEvilFeelsGood below.
* SaveThePrincess: Lupin describes his mission of saving Sakura this way to her.
* SayMyName: As per canon, Zenigata LOVES yelling Lupin's name.
* SecretKeeper: [[spoiler:Jigen]] becomes one for Lupin regarding his resurrection and the Grail War.
* SelectiveObliviousness: It's pretty jarring how Risei's POV changes from a GenreSavvy BadassPreacher to an easily dupable fool whenever Kirei is involved. It ''is'' his son, of course. As long as Risei doesn't really question Kirei's behaviour, he'll probably stay oblivious. (The poor priest still thinks the boy was in love with his wife!)
* ShameIfSomethingHappened: Risei regretfully tells Kirei and Assassin that he has no choice but to [[spoiler:give Sakura back to Zouken]] if Zouken arrives at the church--keyword being ''arrive'' at the church. Risei will be perfectly happy to look the other way if something "unfortunate" happens to Zouken before he reaches the church.
* ShoutOut:
** During the Laughing Peacock heist, Lupin dresses up as a brown-haired, green-eyed waiter called [[Anime/CodeGeass Suzaku.]]
** The mafia men chasing Jigen and Taiga dress like, act like, and have the same verbal tic of saying 'bro' in every sentence as the Tracksuit Draculas from [[Creator/MattFraction Matt Fraction's]] run on ComicBook/{{Hawkeye}}.
** In chapter 21, Sakura wakes up to [[Anime/NeonGenesisEvangelion an unfamiliar ceiling]].
** Lupin mentions that "[[Anime/SpaceDandy the girls at Boobies are out of this world]]".
** The song that Bruno beats up Jigen to is "[[Film/ReservoirDogs Stuck In The Middle With You]]".
* {{Sidekick}}: Kirei is this to his own Servant, and unlike Waver, doesn't seem to realize it.
** Subverted in that Assassin doesn't see either of them in a Master-Servant relationship, but equal standing Partners.
* SkywardScream:
** Archer: MMMMMOOOONNNNGGGGRRRREEELLL!!!
** Zenigata: '''[[HesBack LUPIN!]]'''
* SlasherSmile: Assassin flashes one when he almost burns Lancer alive.
* SmartBall: Risei shows an impressive spike in intelligence in this story. Usually he's the guy that effortlessly gets knifed. Here, he's one of the few people who doesn't underestimate Assassin and tends to be the one who fixes Tokiomi's plans when they go wrong.
* SmitingEvilFeelsGood: TIM seems to be working on an inversion with respect to Kirei Kotomine. Since summoning the Assassin who was known as Lupin III, Lupin has been talking to Kirei about ''how'' he has fun being more important than ''why'' he has fun. Kirei considers himself a very sinful man, not a hero like the trope description expects, but Lupin is widely admired and impressive, partly for whom he targets. Lupin seems to be slowly teaching Kirei that imitating him will lead Kirei to an enjoyable lifestyle, as long as he would PayEvilUntoEvil. It doesn't matter if Kirei enjoys killing people, so long as the people he's killing are people that deserve to be killed.
* SmugSmiler: Assassin is always described to have a cocky smirk on his face. When he's not, it's a sign that shit's about to go down.
* TheSocialExpert: Assassin has an excellent understanding of the human mind and his "Discernment of the Poor" skill enhances this even further. Seeing as ''Fate/Zero'' is one big DysfunctionJunction, this is a great skill to have.
* SomeoneToRememberHimBy: Riko Mine was conceived the first (and only) time Lupin and Fujiko slept together [[spoiler:on the eve of Lupin's death.]]
* SomethingOnlyTheyWouldSay: Jigen verifies Lupin's story via his words and mannerisms.
* SoreLoser: Pretty much the only reason why [[spoiler:Zouken]] tries to [[spoiler:retrieve Sakura]], according to Assassin.
* SpannerInTheWorks: One of Assassin's current goals in non-life is to screw up canon as much as possible.
* SparedByTheAdaptation: [[spoiler:Ryuunosuke]], though in his case that's only so that Zenigata can arrest him.
* SpottingTheThread: Zenigata learns about Tokiomi having a second daughter when he spots a picture with a folded end and examines it. He also catches on to Assassin and Saber's disguises due to Assassin's use of slang and Saber's ill-fitting uniform.
* StealthMentor: Assassin seems to have something planned for Kirei, with him constantly asking Kirei seemingly innocent questions that always make Kirei question himself and what he wants.
* SympatheticInspectorAntagonist: The former TropeNamer has shown up, providing the audience with a Viewpoint Character among the non-mages, trying to work out what's going on in this town. He's ''still'' obsessed with catching Lupin, and has jailed one of the Masters, as well as [[spoiler:Byakuya]], when a lead on [[spoiler:Sakura]] brings them to the [[spoiler:Matou household]].
* TalkToTheFist: Kirei doesn't give Kayneth the time to finish monologuing before attacking him.
* TakingYouWithMe:
** [[spoiler:Lancer]] hoped to at least achieve this in his battle with [[spoiler:Archer]].
** As well as [[spoiler:Berserker]] hoped for with [[spoiler:Archer]]. However it succeeded post-mortem.
* TearsOfJoy: Kariya cries these when [[spoiler: Jigen reveals that Lupin has successfully rescued Sakura from Zouken]].
* TemptingFate: The manager at the Fuyuki National Bank decides to advertise that their bank is safe from Lupin, a man who takes such things as a challenge.
* ThereWasADoor: Kayneth blows a hole in Tokiomi's manor despite there being a perfectly good door. In fact, he blows the hole around the door.
* TheStraightMan: Kotomine Kirei finds himself in this situation due to his Servant.
* TookALevelInBadass: [[spoiler:Pycal, who went from being a fake mage to the head of the Russian mob, and now apparently has actual magical abilities]].
* TranquilFury: Gilgamesh is driven to this after being humiliated again by Lupin and having more of his Noble Phantasms stolen.
* {{Troll}}: Not to the levels of SelfDemonstrating/{{Deadpool}} in TIM's [[Fanfic/FateZeroSense other stories]], but Assassin certainly earns the ire of the three knight classes.
* {{Ubermensch}}: Assassin lives by his own rules and no one else's.
* UnderestimatingBadassery:
** Everyone but Risei and Kiritsugu start out COMPLETELY underestimating Assassin's skills.
*** Played straight by Kiritsugu, in a flashback, when he [[spoiler:first met and therefore underestimated Lupin. As a teen working with Natalia, the two of them were given a job to kill a magus that had contracted Lupin for an artifact. They failed]]. He is ''trying'' to avoid making that mistake again.
** Kayneth underestimates Kirei, and crosses a bit into TooDumbToLive territory. Kayneth believes that hunting down Kotomine Kirei is a good idea. Given that Lancer is still missing Gae Buidhe and that Kirei was able to evenly fight Kiritsugu while impaired in canon... Sola-Ui even lampshades this later on.
** The Owls of Minerva also have this attitude towards Lupin. Crosses over into TooDumbToLive territory since they've clashed with him repeatedly when he was alive, so they really should know better.
** Tokiomi joins the club, making the classic blunder of thinking Zenigata is an incompetent twit just because he can't catch Lupin.
* UnfamiliarCeiling: Happens to Saskura in Chapter 21.
* UnwittingPawn:
** The Count uses [[spoiler:both Lupin and Kirei]] (or at least he thinks so) for the Holy Grail War.
** Assassin uses [[spoiler:Kayneth]], who later passes out upon the realization.
* UriahGambit: Tokiomi ''tries'' to pull one on [[MagnificentBastard Assassin]] in the second chapter, deeming him worthless. It obviously doesn't work.
* VillainDecay:
** Inverted. Originally all of the Servants were completely caught off guard by Lupin's antics, but by the second encounter they wise up to his tricks. Saber realizes that it's just smarter to roll with the insanity instead of fighting it, Lancer invokes ItOnlyWorksOnce, and Archer becomes a NoNonsenseNemesis.
** Caster's another inverted version. Ever since he saw Assassin ''defile'' "Jeanne", he is vehemently willing to go all out on him in their confrontations. [[spoiler: But before he could summon [[OneWingedAngel his strongest monster]] in their last encounter, Saber acted as Jeanne long enough to leave an opening.]]
** Justified for [[spoiler:Zouken. Without the Crest Worms infesting Sakura, Zouken can't use her as either a hostage, host, or plant, and Kariya's too far gone for the Worms' removal to really matter. With Byakuya in jail and Shinji overseas, there's no one else around for Zouken to manipulate. The ''best'' he could do is run away on his own.]]
* WeakButSkilled: Assassin. His stats have Strength and Mana at very low rank compared to other Servants, but he compensates with great Agility and Endurance, outrageous Luck (further increased by the Noble Phantasm "Better Luck Next Time", which allows him to escape certain death), sheer skill, and a Noble Phantasm capable of ''[[DidYouJustScamCthulhu stealing his foes' Noble Phantasms]]''.
* WhamEpisode:
** The origin of the Owls of Minerva, the secret to their new drug, the connection between the Owls and the Association... a LOT is revealed in Chapter 22.
** Chapter 26, full stop. [[spoiler:Both Berserker and Archer bite it, with Archer falling to Lupin's brilliant planning and Jigen's legendary sniping]].
* WhatIsThisThingYouCallLove: Kirei seeks the answer to this question among others.
* WorfHadTheFlu: During Saber and Zenigata's alliance, Saber has to pretend to be a normal human, so she can't fight with her full power against the Eulen-KŁken. Normally, the fight would have lasted two seconds.
* WorthIt: Getting involved in the Grail War, dying from having his body infested by worms, working with Lupin; Kariya was more than willing to go through all of this to save Sakura.
** And when he succeeds in [[spoiler:helping Lupin to kill Archer]], Kariya doesn't even care that he's going to die anymore.
** Kariya also has this attitude because he was able to [[spoiler:not only save Sakura but]] screw over Tokiomi [[spoiler:before his death]].
* WorthyOpponent: This trope is very common.
** Lupin and Zenigata as always. As a matter of fact, one of the few things that angers Lupin is people disrespecting Zenigata.
** Lupin is also constantly pushing Saber to prove that she could be considered a worthy opponent to him, if for no other reason than to keep himself from becoming ''bored'' of the war. As of chapter 20, Saber is doing her own research on Lupin so she can be prepared when he finally does come for her, even calling him "Lupin" rather than "Assassin."
** Assassin weaponizes this trope against Lancer by telling him that he doesn't consider him a worthy opponent, making him slip up.
** Archer tells Lancer that he ''also'' doesn't see him as worthy, causing Lancer to [[spoiler:make the mistake that causes his death]].
** Rider sees Assassin as one, evidenced when he gets ''pissed off'' at Caster when Caster appears to have killed the Assassin.
* WouldntHurtAChild:
** Despite delaying his rescue of Sakura, Lupin would never hurt a child himself.
** Averted with Count Almeida considering that he GLEEFULLY used children in experiments (Some of them he personally raped) back in World War II, among all the other immoral stuff he did in the proceeding years.
* XanatosGambit: Lupin has a flair for these. [[spoiler: Chapter 19 shows the result of his previous chapter's plan. Either [[NoNonsenseNemesis Archer]] or Lancer would die from Kayneth's attack on the Tohsaka residence, eliminating one of his two enemies. Lancer was too weak.]]
* YouHaveFailedMe: [[spoiler:Kayneth]] feels this way about [[spoiler:Lancer]]'s death.
* YouMonster: Count Luis Yu Almeida definitely qualifies. When even the ''Nazis'' think you're a fucked up monster, you've crossed lines upon lines upon lines.
* YourDaysAreNumbered: In a flashback Lupin is visted by an Owl of Minerva, who proclaims this. The number of days he has left? One.
