''Tweeny Witches'' [-(Japanese Title: 魔法少女隊アルス ''Maho Shôjo Tai Arusu'')-] is a 2004 anime by Creator/Studio4C, and is certainly one of the weirder takes on the fairy tale genre.

In modern day Tokyo, we meet Arusu, an 11 year old girl who has a thing for the occult and is especially obsessed with witches and witchcraft, thanks to a book given to her years ago by her DisappearedDad. When some bullies try to steal her book, a mishap sends her falling (literally) into the world of the witches. Almost immediately, she meets Sheila and Eva, two apprentice witches who are close to her age.

Delighted as she is to be in the Witching World, Arusu is less than delighted at how their society is run. Everyone is either miserable or scared, certainly not overjoyed at the reality of magic, whereas she believes magic should be used to make people happy. More disturbing to her is how the witches capture sprites (or fairies) and keep them behind bars for their use in spells. When she releases all the captive sprites back into the wild, the Elder Witch punishes Sheila and Eva with the Curse of Eternal Youth, leaving Arusu duty bound to become an apprentice witch and join them on their quest to recapture the sprites and break her new friends' curse.

As the series continues, Arusu becomes more familiar with magic and her new friends. She also learns more about her new world and its extremely dark underbelly, one which seems intent on tearing everything apart, and is also very interested in that book of hers...

This series was licensed in North America by Creator/MediaBlasters, who dubbed and released it in 2008.

!! This series provides examples of:

* AdventurerArchaeologist: Arusu's dad Jidan.
* AnIcePerson: Sheila.
* AndYourRewardIsClothes: Atelia gives Arusu a witch's outfit from when she was a child.
* BigBad: Grande.
* CatchPhrase: "Anyone can use magic as long as they believe with all their heart!"
* CurtainsMatchTheWindow: Eva (yellowish green) and Sheila (light purple). Arusu also sort of counts, though her eyes come off as gold whereas her hair is always reddish orange.
* CuteWitch: All three witches in the picture.
* DefrostingIceQueen: Sheila.
* {{Determinator}}: According to Arusu, anyone can do magic if they have a heart that believes.
* DisappearedDad: Arusu's. [[spoiler: He lived in Witch Haven for a while with Atelia, but left since he was still married. Atelia... wasn't pleased.]]
* EldritchAbomination: [[spoiler: The thing that feeds off of Eva at the end]].
* FacelessMooks: On both sides: The witches' have mosquito like gas masks while the wizards' wear armor that make them look like sharks.
* FemmeFatalons: Atelia, leader of the witches, has long red nails. Suspiciously, Arusu also favors long, red nails...
* FirstNameBasis: Arusu's mother, Yoko. Arusu never gives her any kind of honorific or respectful title. Considering how Yoko acts, it's understandable why.
* GenkiGirl: Arusu. At one point she's taken on the task of saving the animals normally used for potion ingredients, learning magic, rescuing her friends, and reuniting witches and wizards. Her friends note that [[LampshadeHanging she may have bitten off more then she can chew]].
** Sheila's mom is so similar to Arusu it's scary.
** When cursed with dangerous levels of bad luck, Arusu tries to use the humor of her own misfortunes to get Sheila to smile.
* GirlishPigtails: Eva.
* HandsOffParenting: Yoko is so depressed and / or drunk that Arusu has to do everything. Then again, she still has a sense of humor so there could be hope for her yet. Sheila and her mom have been estranged for years.
* HeelFaceTurn: Sigma.
* HeroicSacrifice: [[spoiler: Jidan. Or maybe not...]]
* IdiotHero: Arusu.
* InstantAwesomeJustAddDragons: Sheila's house can turn into one.
* InstrumentalThemeTune: The opening song.

* LadyLand: Witch Haven.
* MacGuffin: The True Magic book Arusu's dad left with her.
* {{Magitek}}: That which powers the Warlocks.
* [[spoiler: MessianicArchetype: Arusu.]]
* MiniSeries: Very mini -- the episodes are only 12 1/2 minutes long, counting the (very long) opening in odd numbered episodes, and the ending and preview in the even numbered episodes. Without that, the episodes are about nine to ten minutes a piece.
** There are 40 half length episodes in the main storyline. Combining them into a standard 25 minute slot yields 20. Add to that the six normal-length side story episodes released later, and you've got a full season.
* MissingMom: Sheila's decided to stay with her wizard husband, despite giving birth to Sheila, which would have allowed her to return to Witch Haven.
* MotherNatureFatherScience / ScienceVsMagic: The witches live in a lush valley surrounded by nature, while the wizards (who have lost the ability to use magic, save for a few very old outcasts) live in an underground high-tech fortress. Appropriately they used to all live together, but then the men were taken over by what amounted to warlike scientists.
* NotAllowedToGrowUp: Literally. Sheila and Eva are cursed to remain young girls. [[spoiler: They get better.]]
* NotSoDifferent: Sheila and Sigma.
* OlderThanTheyLook: Ever so slightly. Two of the PowerTrio were punished by being unable to grow older. But not a lot of time passes in story after they're cursed.
* PantyShot: Bloomer Shots, actually. Of Eva.
* PowerTrio:
** Id: Arusu.
** Ego: Eva.
** Super-Ego: Sheila.
* RedOniBlueOni: Arusu is the red to Sheila's blue.
* SceneryPorn: Many of the backgrounds are a real visual treat.
* ShockAndAwe: Arusu whenever she does anything.
* ShoutOut: The masks of the witches' mooks look a bit like that [[Anime/NeonGenesisEvangelion first angel]] with a busted "nose."
** Episode 20 has Arusu doing a [[Series/KamenRider Kamen Rider Ichigo henshin pose]].
* SpellMyNameWithAnS: Arusu. This is her name in both Japanese and English, but the fansubs wrongly called her "Alice."
* TheSpock: Sheila.
* TitleDrop: Episode 20 has Arusu literally say "Magical Girl Squad."
* {{Tomboy}}: Arusu.
* TrailersAlwaysLie: [[https://www.youtube.com/watch?v=CSkrKXp2Ces The promo trailer]] looked ''awesome'' and got a lot of people excited about the series. Thing is, that was actually a mini-pilot and not an actual trailer.
* UtopiaJustifiesTheMeans: Both Witch Haven and Wizard Fortress are amazing places of magic and technology, respectively, but both have dark sides: The warlike Wizards are very authoritarian and the witches have a habit of banishing witches to the desert to live with the wizards [[spoiler: or, if they've been ''really'' bad, making them risk going through a very unstable portal into ''our'' world, where neither magic nor technology exists at that level.]]
* WideEyedIdealist: Arusu.
* WildChild: Lennon, [[spoiler: Arusu's half brother who was lost in the vortex between the magical world and the real world.]]
