-> ''It was said'' --\\
''There was a mansion that rested on top of a hill, and within it there lived two witches.''\\


It is the late 1980s. Rumors of a witch living inside an old mansion circulate in the city. Unbeknownst to observers, living inside the mansion is an actual witch, Alice Kuonji, a stoic woman and a magus hiding in the present day. Under her tutelage studies [[VisualNovel/{{Tsukihime}} Aoko Aozaki]], a high school student studying magecraft as the head of the Aozaki family. As magi, the two of them secretly fight any threat that enters their town.

Things start to change when a young man unfamiliar with city life, Soujuurou Shizuki, enters their lives. Slowly, he affects the lives of these two magi. And so their story begins...

''Mahou Tsukai no Yoru - Witch on the Holy Night'' is a VisualNovel set in the {{Franchise/Nasuverse}}. Originally a five-hundred-page novel penned by Kinoko Nasu, it was never publicly released and only a handful of copies were distributed. It was announced for a visual novel remake in 2008, but it got stuck in DevelopmentHell several times before finally being released on April 12, 2012. A translation of the demo text can be read [[http://emptyboundaries.wordpress.com/2012/01/26/there-was-a-mansion-that-rested-on-top-of-a-hill here]].

Unlike the other Type-Moon visual novels, ''Mahoyo'' is a linear novel with no branching plot lines. It is also Type-Moon's first all-ages visual novel. [[NoExportForYou Which means it might actually get an official release outside of Japan. We won't hold our breath though.]]

The game has two sequels planned, but WordOfGod is that serious production won't start until the Tsukihime remake is finished. [[DevelopmentHell Here we go again.]]

Not to be confused with another manga called ''[[Manga/TheAncientMagusBride Mahou Tsukai no Yome]]''.
!!This visual novel contains examples of:
* AllOfTheOtherReindeer: Lugh's backstory.
* AmusementParkOfDoom: The main setting of Chapter 5 and where the climactic magic clash between Aoko and [[spoiler: Alice with Flat Snark]] takes place in. Also, the dissidents of the park are [[EverythingIsTryingToKillYou constantly out trying to kill]] both Aoko and Soujuurou there.
* AndNowForSomeoneCompletelyDifferent: The story constantly switches between the points of view of different characters, though [[TheProtagonist Aoko]] and [[{{Deuteragonist}} Soujuurou]] still retain the main focus. In the bonus chapter included in the visual novel, [[ADayInTheLimelight Kojika]] replaces them as the protagonist.
* {{Animorphism}}: Lugh can take either the form of a pretty boy or a wolf.
* {{Backstory}}: The entire novel revolves around the high school life of Aoko, a major character in ''VisualNovel/{{Tsukihime}}'' and ''VideoGame/MeltyBlood''.
* BackToBackBadasses: Aoko and Soujuurou in Chapter 5.
* BadassNormal: Soujuurou.
* BigFancyHouse: The Kuonji Mansion, the house Alice, Aoko, and later, Soujuurou reside in.
* BrokeYourArmPunchingOutCthulhu: [[spoiler: Soujuurou literally breaks his arm punching Lugh.]]
* ChekhovsGunman: [[spoiler: Touko]] shows up as early as Chapter 2 but only as a brief cameo and doesn't get to take a more major role until further chapters later.
* ChildSoldier: [[spoiler: Soujuurou came from the same organization as Souichirou, from ''[[VisualNovel/FateStayNight Fate/stay night]]'']]
* ChurchMilitant: Eiri Fumizuka, the priest in charge of the local church in the story, is an Executor who was said to have killed a witch in the past.
* CountryMouse: Soujuurou.
** NaiveNewcomer: Because of this, he readily accepts the existence of magic as just another wonder of the city.
* CreepyDoll: More like creepy puppet, but Aoko and Soujuurou encounter one in the hall of mirrors. Its purposeful resemblance to Aoko and its strange bodily proportions and [[NightmareFace creepy face]] land it a place in the UncannyValley territory.
* DeathIsCheap: [[spoiler: Just when everyone thought that Soujuurou is going to be KilledOffForReal, Aoko activates Blue for the first time and reverses his death.]]
* DidYouJustPunchOutCthulhu: [[spoiler:Soujuurou takes down Lugh, a two thousand year old NatureSpirit whom not even Aoko could defeat, by punching him in the heart and hitting his back with an elbow blow, which freaks Lugh out due to it being a new experience and actually getting beaten in fisticuffs.]]
* TheEighties: The setting of the story.
* EmotionControl: [[spoiler:Using a suggestion spell, Aoko can remove fear from Soujuurou.]]
* EldritchAbomination: While nearly all of Alice's Ploys count as this, [[spoiler: Flat Snark]] takes the cake for its overall creepiness, level of power, and [[spoiler: for being the only Ploy to act independently and outright disobey Alice.]]
* EldritchLocation: After [[spoiler: Flat Snark]] does its magic, the entire park of Kitsy Land gets transformed into this, with the place being constantly warped and expanded at every turn to completely screw with Aoko and Soujuurou. Not only that, but they have to deal with its residents trying to kill them on the spot. Heck, it was even sadistic enough to give them a brief [[HopeSpot hope spot]] by showing them the exit...''which was transformed into multiple gates leading into more gates that stretched on for miles.''
* EyeScream: [[spoiler: Touko's Mystic Eyes explode during her climactic clash with Aoko.]]
* FairyTaleMotifs: Alice's magic revolves around fairy tales and nursery rhymes.
* {{Familiar}}: Lugh to Touko.
* {{Golem}}: Alice has one. Touko has... some.
* HalfTheManHeUsedToBe: [[spoiler:Soujuurou, courtesy of Touko. But he got better.]]
* HomeFieldAdvantage: [[spoiler:The Flat Snark is a barrier-erecting ploy that brings abandoned things to life as fairy tales. In an abandoned amusement park based on fairy tales, it is at its most powerful.]]
* HotBlooded: Aoko.
* HypnoticEyes: [[spoiler: Touko's self made Mystic Eyes of Binding that can trap people in illusions. Finally explained what the eye is after the casual mention in ''LightNovel/KaraNoKyoukai'' that Touko had Mystic Eyes.]]
* IdiotHero: Soujuurou. The guy is just plain clueless.
* InnocentCohabitation: Soujuurou begins to reside with Aoko and Alice, two girls, in their mansion starting from Chapter 6.
* ItOnlyWorksOnce: [[spoiler: Flat Snark, Alice's most powerful ploy, can never be used again after Aoko beats it, according to WordOfGod.]]
* KilledToUpholdTheMasquerade: Aoko explains that this is usually done, not to avoid [[BurnTheWitch persecution]], but because the more people know about sorcery, the weaker it gets as a whole. So to preserve it, they keep it a secret.
* KungFuWizard: Aoko.
* LaserGuidedAmnesia: There is a Rune of Oblivion that can do this, but neither Alice nor Aoko know it by heart and require three months to utilize it, hence why they didn't lead with it instead of trying to [[spoiler:kill Soujuurou.]]
* LeaveNoWitnesses: [[spoiler:Soujuurou stumbling through Alice's barrier leads to both Aoko and Alice trying to kill him a different points. Aoko decides against it and defeats Alice to ensure that this trope is [[AvertedTrope averted]].]]
* LighterAndSofter: Compared to ''LightNovel/KaraNoKyoukai'', ''VisualNovel/{{Tsukihime}}'', and ''VisualNovel/FateStayNight'', ''Mahoyo's'' story is pretty lighthearted in tone, has more SliceOfLife scenarios compared to the Nasuverse works mentioned above, and has almost zero deaths and angst in it. [[spoiler: In fact, the only major death here didn't even stick long.]]
* MagicMirror: Alice has one that she uses to look over the city or manor.
* MagicPrerequisite: Alice requires certain things for her ploys to work properly, including a vessel. The Thames Troll requires a river nearby to come out, for example. [[spoiler:The Flat Snark brings things that are abandoned to life as fairy tales, so in a business district it was virtually harmless.]]
* MarionetteMaster: Touko.
* MonsterClown: One appears in Chapter 5 and this gives both Aoko, Soujuurou ''and'' the reader a chance to react with an appropriate OhCrap face. The JumpScare that involves its appearance doesn't help.
* MythologyGag:
** In one chapter, our resident {{Tsundere}} mage from a relatively well-known magus family chases the local [[NiceGuy nice]] IdiotHero who is new at the whole magic business down a corridor and attempts to blast him with her magic in an attempt to kill him, only for her not to go through with it thanks to a long-haired enemy's sudden interference in her assault coupled with the {{Tsundere}}'s own hesitation towards killing the guy. [[VisualNovel/FateStayNight Sound]] [[Anime/FateStayNightUnlimitedBladeWorks familiar?]]
** The school Alice attends is the same school [[LightNovel/KaraNoKyoukai Azaka, Fujino, Shizune, and Ouji]] study in.
* NighInvulnerability: Lugh {{No Sell}}s a kick that could break a tree in half.
** Alice's fairytale familiars are all invulnerable to modern tech.
* NurseryRhyme: Alice uses these as incantations for her magic.
* PerpetualMotionMonster: The puppet that comes after Aoko uses {{Curse}}s to power itself and can curse itself as well, meaning it would never run out of power.
* PlayboyBunny: Aoko gets to use one in an Extra Scene. Maybe a compensation for the lack of H.
* PowerDyesYourHair: Aoko's use of the [[spoiler:Fifth Magic to fast-forward her own time]] resulted in her hair turning red.
* ResetButton: [[spoiler: Aoko uses her time-manipulating Fifth Magic to make so that Soujuurou's death never occurred by basically ripping the minutes of his death out of the timeline and flinging them into the distant future.]]
* ShipTease: Soujuurou has some moments with both [[RedHeadedHeroine Aoko]] and [[SugarAndIcePersonality Alice]].
* SiblingRivalry: A very ugly one between Aoko and [[LightNovel/KaraNoKyoukai Touko]] over the succession of the family magecraft.
* TheStoic: Alice is described as such. She barely shows any emotion, but [[DefrostingIceQueen seems to have warmed up]] to Aoko and Soujuurou.
* TimeMaster: Whoever controls the Fifth Magic.
* {{Tsundere}}: Aoko to Soujuurou.
* TwoGirlsAndAGuy: Aoko, Alice, and Soujuurou respectively.
* WeCanRuleTogether: Touko offers something akin to this to Soujuurou. In a bit of a subversion, however, Touko states that he would not be so much her equal, but more her [[FriendsWithBenefits mook with benefits]].
* WhatTheHellHero: [[spoiler: The nature of the fifth magic, blue, has some side effects due to the laws of thermodynamics. In the process of rescuing Soujuuro Aoko basically removes a large amount of energy and flings them into the future, requiring the world to correct itself. Touko is mortified at the potential consequences of moving, removing and using up the amount of energy Blue does and calls her out on it.]]
* WholesomeCrossdresser: Ritsuka enjoys crossdressing as a hobby, [[spoiler:and Aoko's first crush being on Ritsuka-in-drag mortified her so much that she now has a lot of antipathy for romance in general]].
* WitchSpecies: Magus as usual, but also actual witches like Alice.
* WithAFriendAndAStranger: Aoko is the protagonist, Alice is her childhood friend and close confidant, and Soujuurou is the stranger whose meeting with Aoko changes both their lives on the get go.
