-->''Dear Lord, forgive our deception. One, two... three~!''

''Kaitou Saint Tail'', translated as ''Phantom Thief Saint Tail, Mysterious Thief Saint Tail, Saint Tail'' or, as known by {{Tokyopop}}, ''Sweet Tales of Saint Tail''. Based on the manga by Tachikawa Megumi.

The titular thief is a 14-year-old MagicalGirl named Haneoka Meimi, daughter of a magician and a {{Kaitou}}-turned-housewife, who goes to a Catholic school. One of her classmates, and her SecretKeeper, is a [[NunsAreMikos trainee nun]] named Mimori Seira; on duty, she listens to the troubles of the people that visit her church. If someone's been the victim of larceny, Seira tells Meimi all the details, both from the testimony and from her own sneaking around. Meimi transforms into Saint Tail, uses a combination of her father's magic tricks and her mother's stealth, and steals the stuff back. Saint Tail is idolized as a hero by the girls at school, but the police have an obligation to catch her, even if all she's doing is returning things to their rightful owners. In comes Meimi's classmate, detective-in-training and on-off crush Asuka Jr., [[SympatheticInspectorAntagonist who becomes obsessed with catching Saint Tail.]]

Asuka begins to fall for both Meimi and Saint Tail, and Meimi becomes jealous of her own alter ego. A few other characters are introduced that have it in for Saint Tail, and Seira continues to remind her that even if she does have feelings for Asuka, she can't let her identity slip. Meanwhile, although Meimi's mother, who had far less altruistic motives than Meimi does, was never captured, her past as a phantom thief is catching up with her.

!!This program provides examples of:
* AnimeCatholicism
* BelligerentSexualTension: Meimi and Asuka Jr. Oh boy... out of all magical shoujo, they should be FAMOUS for this.
* CallingCard: Saint Tail's use of stage magic is one. Also, Saint Tail has the habit of sending Asuka Jr. warnings of where and when she'll commit a caper ''on his request'' (he dared her, and she accepted), warnings that [[CrowningMomentOfHeartwarming look suspiciously like spectacular and very romantic requests for dates]] ([[ObliviousToLove not that Asuka Jr. noticed the latter until it was shoved on his face...]]).
* CanonForeigner: Mayor Morinaka and Asuka sr.: while known to exist since the start in the manga, they first appear in the very first anime episode, and when they finally appear in the manga it's with their anime looks and characterization.
* CatholicSchoolGirlsRule: In spite of all characters going to a catholic school, the one hit by this is ''Seira'', whose good looks have been remarked by complete strangers and has a love interest who ''knows'' she's a nun-in-training. Too bad that Seira is not only not interested (to the point she's oblivious about a rather romantic romantic tradition of the school that even the ''transfer student'' knows), but completely ObliviousToLove...
* ChristmasEpisode
* ChristianityIsCatholic: And so is the whole town, apparently, despite being in a [[FridgeLogic predominantly Shinto country.]]
* ClarkKenting: Subverted. The only differences between Meimi and Saint Tail are the clothes and Saint Tail's ponytail, but Saint Tail takes care to keep people from seeing her face. Meimi and Saint Tail also act differently (to the point that Saint Tail started showing off after putting herself in a situation where Meimi had nearly fainted out of shyness), and Meimi doesn't show how good an athlete and magician she is to avoid suspicion (and the one time she slipped and accidentally showed her agility, Rina added it to the list of hints that Meimi could be Saint Tail).
* ClingyJealousGirl: Rina.
* CutenessProximity: Rosemary gets this in presence of both Meimi and Asuka Jr. [[FoeYay She also mentions that Meimi was just as cute as her mother in the past]].
** Also, it could happen ''[[TheFourthWallWillNotSaveYou to the viewer]]'' when Ruby is on screen or whenever the characters are shown in {{Chibi}} form.
* DarkMagicalGirl: Kaitou Lucifer, i.e. Meimi's mother Eimi, before Meimi's father convinced Eimi to turn good and they married.
* DatingCatwoman
* {{Determinator}}: Asuka Jr doesn't give up on catching Saint Tail for pretty much the whole series no matter how many times he fails.
* EmbarrassingFirstName: Rosemary's true name is Kabako Sendo. Why is it embarrassing? Well, Kabako can be translated as ''Miss Hippopotamus''. For obvious reasons, calling her by name in public is her BerserkButton.
* FlashedBadgeHijack: Asuka jr. once did it to the bicycle of a ''police officer on patrol''.
* GenerationXerox: Religious-themed phantom thief runs from chief detective Asuka, who dedicates his life to unmasking her. Now are we talking about Eimi and Asuka Sr. or Meimi and Asuka Jr.? One big exception, though: Meimi steals from thieves and gives to the rightful owners, but Eimi stole from the rich and gave to herself.
* GenreSavvy: Both Asuka jr. and his father know that Saint Tail steals only to help people. With time, Saint Tail's warning she'd steal something became enough to make Asuka sr. investigate how it was obtained and if it was the genuine article, just in time to find out why he has to arrest the 'theft victim' immediately after the caper.
* TheGhost: Mayor Morinaka and ''especially'' Asuka sr. in the manga: Morinaka doesn't show up in person until the two-parter of chapters 18 and, ''three quarters through the storyline'' (and promptly disappears again), while Asuka sr. appears only in the final panel of the prequel chapter published ''after the end of the manga''.
* HugeSchoolgirl: Rina is easily the tallest girl in the class, and the second tallest student period (only Sawatari is slightly taller), and she's rather shocked, and flustered, when the very short Asuka jr. hits his grown spurt and becomes taller than her.
* ImportantHairCut: At the end of the manga series, [[spoiler: after the skip forward in time, it is revealed that Meimi cut her hair. Symbolically, it points out that she is no longer Saint Tail.]]
* ImpossiblyAwesomeMagicTrick: The main character is the daughter of an ImpossibleThief and a StageMagician. Of course this trope gets involved. Despite being a MagicalGirl, her "magic" is explicitly all stage magic, but she routinely pulls off impossible feats, such as being carried off by just a [[{{Balloonacy}} a handful of balloons]].
* IWantMyBelovedToBeHappy: Once Meimi and Asuka Jr. gets together, Rina, previously ''the'' ClingyJealousGirl of the series, starts supporting them, even helping Meimi to recover her courage when Asuka Jr. disappears.
* JustLikeRobinHood: Saint Tail steals from thieves and gives them back to their owners.
* KarmaHoudini: Rosemary kidnaps Asuka Jr., puts Meimi through hell, and threatens both of their lives. In the end, she simply walks away after seeing their love for one another and goes on to rob people in other towns.
* LoveLetter: [[LampshadeHanging As pointed out by Pandora]], Saint Tail's 'burglary warnings' double as such.
** LoveLetterLunacy: Said love letters took the forms of notes popping out from the strangest places (including ''a ball that had just hit Asuka jr. in the face''), messages written on his face while he sleeps, [[CrowningMomentOfHeartwarming written with food in a lunchbox she prepared for him]], or ''[[CovertPervert his bath towel as he was taking a shower]]'', and even an announcement made to the whole town ''with a blimp''.
* MagicalGirl: Both figuratively and literally.
* MarketBasedTitle: The first release of the anime and manga, from TokyoPop, called it ''Sweet Tales of Saint Tail'', because the phantom thief genre on its own wouldn't attract young girls.
* MegatonPunch: Rina is rather prone to dish them out, having sent flying even a couple cops.
* MissionFromGod: It's never outwardly stated, but Meimi seems to have been given her powers from {{God}}. Her InTheNameOfTheMoon speech indicates that at least ''she'' thinks so.
* MysteriousParent: Mysterious to us; Meimi knew all along, and it's strongly hinted from the beginning.
* NunsAreMikos: Tachikawa Megumi freely admits that she assumed things about nuns when creating Seira that are only true of miko.
* NunTooHoly: Seira has lied and violated the confessional secret multiple times, is in cahoot with a thief, and, in the manga, even committed one theft herself (the key of a confessional she 'reserved' for private talks with Meimi). True, she doesn't exactly like any of that (she justifies it as [[IDidWhatIHadToDo having to do it to redress wrongs]], and even gave herself a WhatTheHellHero in one occasion), but she still did, and even was the one to come up with the idea to send Meimi around as Saint Tail (and coined the name) to [[JustLikeRobinHood steal stolen things and give them back to their legitimate owners]]... And the DistantFinale implies she never stopped violating the confessional secret, only now she does it to point ''Asuka Jr.'' at the wrongs to redress.
** NaughtyNun: Played with: Seira keeps her vow of chastity, but ends up as Sawatari's love interest (and, [[ObliviousToLove when she finally realizes his feelings]], there are hints she may reciprocate them, even if she'll keep them strictly platonic), and her good looks are remarked multiple times, ''especially when wearing her nun garb''.
* ObliviousToLove: Asuka Jr. is this about not only Meimi's feelings, but also the much more evident ones of Rina and Meimi as Saint Tail (whose 'burglary warnings' look suspiciously like love letters, with some being impossible to mistake for anything else). [[LampshadeHanging Lampshaded]] by Pandora when [[ItMakesSenseInContext Asuka Jr. receives as promised the warning Saint Tail would steal him]] and calls it a burglary warning and she corrects him as it's an ''obvious'' love letter.
** Also, Seira: near the end of the manga Sawatari falls for her, yet she doesn't realize his feelings (which are just as evident as Rina's and Saint Tail for Asuka) until he makes her a barely-veiled declaration.
* OnlySixFaces: As with all Tachikawa works, even now though her drawing style has [[http://www6.plala.or.jp/mts/irasuto1.htm changed over the years]].
* PhantomThief: Meimi/Saint Tail
* TheRival: Rina to Meimi for Asuka's affections. Rosemary to Eimi/Kaito Lucifer in the past.
* RoofHopping: Used often by Saint Tail.
* SchoolNewspaperNewsHound: Sawatari.
* SecretKeeper: Asuka jr., in the end (Seira doesn't count because she's an accomplice).
** In the anime, Eimi is implied to know that her daughter is Saint Tail, and actually covered her once.
* SureLetsGoWithThat: The manga reveals Saint Tail got started this way: after what was supposed to be Saint Tail's ''only'' outing (and even before the name was coined) to recover a stolen key, the school journal published a bad picture of her taken by Asuka Jr. and dubbed her a PhantomThief, and Seira, in her [[NunTooHoly nun garb]], told Meimi she would be one with the name of Saint Tail. Meimi, not thinking about it as a MissionFromGod yet, was less than amused.
* SympatheticInspectorAntagonist: Asuka Jr.
** Also his father Asuka Sr., who in his youth chased [[spoiler: Meimi's mother when she was the phantom thief Lucifer]] and is shown being the one chasing Saint Tail before Asuka Jr. nearly catches her, getting the mayor to make him take over. He's still the one who arrests the crooks exposed by Saint Tail.
* TransformationSequence
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Lizards?]]: Meimi is absolutely terrified by lizards. [[HilarityEnsues Hilarity Ensued]] when a pet Saint Tail was supposed to steal happened to be a particularly large one.
