[[caption-width-right:324:Where there is Mogeko, there is nightmare.]]

''Mogeko Castle'' is a surreal horror game created by Creator/DeepSeaPrisoner (aka Mogeko) in UsefulNotes/RPGMaker. The main creatures are based off of the Geko cat. The game was originally made in RPG Maker 2000 and released on April 1st, 2012. A [[VideogameRemake remake]] made in RPG Maker VX Ace was released on early 2014.

Yonaka Kurai, an ordinary high school girl, is taking the bus home. Her dearly beloved brother has finally come home, and she's looking forward to seeing him again. During the ride back, she drifts off, and reawakens to find the bus has stopped at an unfamiliar station.

While looking around, she encounters some strange yellow, cat-like creatures: the Mogeko. These odd little creatures appear to be [[{{Ephebophile}} disturbingly obsessed with high school girls]], and want to 'play with her'... Soon, Yonaka finds herself trapped inside the titular Mogeko Castle, searching for a way to escape back home.

Along her journey to the seventh floor, she encounters various Mogeko, which help her out. One of them, after she sets him free, joins her on her quest. Can she escape the castle with her sanity intact or will the Mogeko succeed with their perverted plans for her?

This game was translated by vgperson. Those interested in playing can find it [[http://www.vgperson.com/games/mogekocastle.htm over here]]. Be forewarned, however, that the game contains some potentially triggering content, mainly violence and implied rape. The author rated the game 'ages 15 and up', but acknowledges this may be too low from a non-Japanese perspective.

Mogeko's other works are ''VideoGame/TheGrayGarden'' and ''[[VideoGame/{{Wadanohara}} Wadanohara and the Great Blue Sea]]''.
----
!!''Mogeko Castle'' provides examples of:
* AllJustADream: Yonaka wonders if the castle was just this upon finding herself [[spoiler:on a bus back home]]. However, [[ThatWasNotADream she realizes otherwise]] after noticing [[spoiler:the blood on her hands]].
* AllLowercaseLetters: King mogeko is distinguished from the usual Mogeko by the fact his name is in lowercase. This extends so far that somebody screams his name as "KING mOGEKO!"
* [[AllMenArePerverts All Mogekos Are Perverts]]: Almost every single Mogeko Yonaka meets are after Yonaka because they want to have sex with her. They actually confess that they love high school girls, which might imply that they've abducted countless girls before Yonaka and either raped and/or murdered them. They also have a wide collection of porn and record their masturbation sessions.
* AlmostDeadGuy: [[spoiler:Hasu]] has been tortured and crucified by Moge-ko by the time you find them, yet hangs on long enough to explain how they were caught and about the castle's history before slowly succumbing to their injuries.
* AmbiguousSituation: Comes into play in [[spoiler:the Happy Ending]], which leaves [[spoiler:Yonaka's status]] deliberately unclear. [[spoiler:Is she trapped back in Mogeko Castle, or is she back home and the final scene just symbolic of her mental state? Is King mogeko drugging her or is she on antipsychotics/antidepressants?]]
* AnimalisticAbomination: The fifth floor has one of these that eats Mofukos. Moge-ko lets it out of its cage to help chase Yonaka and Defect Mogeko.
* ArmorPiercingQuestion: Moge-ko asks Yonaka if she really wants to return home and she stumbles over her answer for a moment.
* AttemptedRape: The majority of the dialogue between Yonaka and the Mogekos is the latter alluding to what they're about to do to her, then {{Zerg Rush}}ing her to try and make it happen. [[spoiler:[[MultipleEndings The first Bad End]] and most instances of a standard GameOver comprises of them getting exactly what they're after.]]
* AxCrazy: Several Mogekos qualify for this trope, but Moge-ko is in a league of her own.
* {{BFG}}: Yonaka and Defect Mogeko [[ItMakesJustAsMuchSenseInContext find a RPG in the hospital]] and puts it to use later. The first time Defect Mogeko uses it he tries to kill Moge-ko and the giant man eating monster with it, only for Moge-ko to NoSell it with a force field. The second time he uses it on King mogeko, which catches him off guard and blows up the throne room.
* BigBadEnsemble: There are three antagonists Yonaka Kurai faces in her quest to escape the titular castle:
** [[TheCaligula King mogeko]] created the titular castle and the [[CuteAndPsycho Mogeko species]] and is trapping Yonaka inside so they can rape her.
** [[DragonInChief Moge-ko]], a sadistic Mogeko girl who is the king's enforcer but terrifies even him and wants Yonaka to herself.
** [[spoiler:Shinya Kurai, Yonaka's brother, killed their parents and wants to kill Yonaka herself, but is [[PlotIrrelevantVillain otherwise unrelated to the main plot]].]]
* BigBrotherWorship: Yonaka thinks very highly of her brother.
** In the bonus room, one of the characters is bold enough to ask if this borders on BrotherSisterIncest. Yonaka denies this idea, of course.
* BittersweetEnding: Regardless of if you get the Normal or Happy Ending, [[spoiler:Defect Mogeko and Shinya are dead]].
* BlackComedy: This is one way to look at the game, hidden among all of the perverted nature of the Mogeko and the homicidal behavior of Moge-ko.
* BloodSplatteredInnocents: Yonaka ends up this way after [[spoiler:Nega-Mogeko is shot]].
* BookEnds: The game's FramingDevice is a Mogeko telling a bedtime story. In the Happy End, we return to this scene [[spoiler:and learn it's King mogeko speaking to Yonaka]].
* BreakTheCutie: Yonaka, at an approximate rate of [[TraumaCongaLine once every 10 minutes]]. It starts with [[AttemptedRape a very clear rape threat]], [[FromBadToWorse and somehow manages to get worse]].
** By the normal end, [[spoiler:she ''[[FaceHeelTurn snaps]]'' and becomes a WoobieDestroyerOfWorlds]].
* BrokenAesop: While Yonaka comes to the conclusion that running away won't solve her problems, the two endings she can get after coming to this conclusion are both [[BittersweetEnding unpleasant]]: her happiest ending comes from running away with Defect Mogeko.
* ButThouMust:
** Given that Yonaka's already met and is running from the perverted Mogeko, and the castle has a giant Mogeko head forming one of the roofs, you'd think that heading inside would be the last thing she wants to do. However, choosing not to enter leads to the first Bad Ending.
** A few 'choices' ask if you want to take a certain action, with your options being 'Yes', 'Hai', or 'OK!'
* TheCaligula: [[DragonInChief Moge-ko]] and [[BigBad King mogeko.]]
* {{Cap}}: Any item you can repeatedly acquire, has a limit of 99 of that item in your inventory.
* ChekhovsGun: The [[spoiler:rocket launcher]] doubles as a bit of a boomerang; the first time it's used, it appears to be wasted with little effect. However, when [[spoiler:King mogeko appears, Defect Mogeko whips it out again and uses it more effectively]].
* ContentWarnings: The game starts with a warning about its violence and sexual themes.
* CruelTwistEnding: [[spoiler:The "Happy End" initially seems like just that, but then reveals that King mogeko was the one reading the story, he's reading it to Yonaka, and will continue to torture her for all eternity.]]
* CulturePolice: Mogeko who deviate from Mogeko Castle's social norms are rounded up and executed. Social deviants include, but are not limited to, Mogeko who have qualms about sexual assault or ''just don't like prosciutto that much''. Only the Seven Special Mogeko are exempt to a degree.
* CuteAndPsycho: The Mogekos may look like {{Cute Kitten}}s with curly tails, but are disturbingly obsessive and casual about violence and rape. Moge-ko is [[AxCrazy even worse about the violence]].
* DidTheyOrDidntThey: One Mogeko sleeping in a bed asks Yonaka to sleep with him. She can accept. Nothing is shown and nothing horrific occurs, leaving what happened ambiguous. Maybe they just cuddled...?
** Though it's worth mentioning that after the scene, Yonaka's Student ID changes from 'Female Student' to 'Woman'.
* DoubleEntendre: The fifth bad ending sounds almost... sexual. Compared to what the game offers, it wouldn't be too surprising.
* DoubleStandardRapeFemaleOnFemale: Averted. Moge-ko's violent lust for Yonaka is played for horror, just like every other Mogeko.
* DownerEnding: [[spoiler:The so-called Happy End leaves Yonaka with a dead brother and a broken mind, either TrappedInAnotherWorld or just haunted by King mogeko as one of her personal demons.]]
* TheDragon: Moge-ko.
** DragonInChief: Even ''[[TheCaligula King mogeko]]'' is terrified of [[CuteAndPsycho Moge-ko]].
* DramaPreservingHandicap: When Yonaka is hiding from a Mogeko in the storage room, he mentions that he'd be able to track her down by her scent much easier if not for his pesky hay fever.
* EldritchLocation: The titular castle has normal-looking architecture at first, but its environments get increasingly weird while going through its floors.
* EmotionlessGirl: Yonaka. She definitely has WhenSheSmiles moments in the game.
* EscapeSequence: At several points, Yonaka must flee from oncoming hordes of Mogeko. Hope you don't take a wrong turn—!
** Moge-ko joins in on the fun twice, once with a horde of Mogekos and again with a giant maneating monster.
* EvilCounterpart: {{Inverted}} with [[spoiler:Nega-Mogeko]], who is explictedly a Good Counterpart of King mogeko. As his complete opposite, they don't share any of the usual Mogeko traits with him, meaning they aren't a selfish, PsychopathicManChild.
* EvilGloating: Moge-ko and King mogeko both engage in this whenever they get the upper hand.
* EvilerThanThou: King mogeko is obsessed with high school girls, sex, killing, and prosciutto. Moge-ko is feared even by ''King mogeko'' for her split personality, unpredictable nature, and being brutally sadistic in her tortures. It says something when the King wants her dead.
** In the normal ending, [[spoiler:Yonaka usurps all three of the major villains to become Lord Prosciutto, the new Mogeko ruler, and the sequel's trailer implies that [[RogueProtagonist she will be the main villain]]]].
* EyesDoNotBelongThere: Several horrific elements involve unnaturally realistic eyes in contrast with the usual art style. For instance, the cover of the "Scary Book" found in Moge-ko's room.
* TheFatalist: Defect Mogeko is initially resigned to his fate when he meets Yonaka, but becomes convinced while helping her that it's possible to ScrewDestiny and help her escape.
* FisherKingdom: Mogeko Castle is implied to be one; many of the Special Mogeko mention that it was originally a much nicer place to live before [[spoiler:King mogeko]] arrived and started reshaping it to their will.
* {{Foreshadowing}}:
** Various portraits show Mogeko with either [[TheBlank completely blank faces]] or [[{{Cyclops}} a single creepy eye]] in the middle of their face. [[spoiler:Both of these are depicting King mogeko after he TurnsRed.]]
** One Mogeko mentions that he'd have an easier time tracking down Yonaka by her scent if he wasn't suffering from hay fever. Near the end of the game, this comes up again when [[spoiler:Nega-Mogeko tells Yonaka that the stench of his blood should cover her scent and make it easier for her to escape unnoticed]].
** Several times, Yonaka is asked if she ''really'' wants to escape. [[spoiler:[[MortonsFork Neither of the two "true" endings are particularly happy.]]]]
** When Mofurru tells Yonaka about the symptoms of blancfluff parasite infection, Defect Mogeko tells her that it doesn't affect humans or the Seven Special Mogekos. [[spoiler:Defect Mogeko is actually Nega-Mogeko, the seventh special Mogeko.]]
** The choice leading to the Happy Ending is labeled [[spoiler:[[CruelTwistEnding "On the Path to Falsehood"]]]].
** Despite generally being a [[NiceGuy Nice Girl,]] Yonaka can do some cruel things to certain Mogekos, none of which actually do anything to harm her. In certain choices, she [[spoiler:[[ButThouMust will not allow you to say no to killing]]]]. [[spoiler:[[UngratefulBastard She can even kill the ones that help her.]]]] The title screen shows her with [[RedEyesTakeWarning creepy red eyes,]] and [[spoiler:a late-game InterfaceScrew gives her pause menu picture red eyes ''and'' a PsychoticSmirk]]. She's also an EmotionlessGirl; worryingly, [[spoiler:she doesn't seem the least bit surprised with what her brother [[SelfMadeOrphan has done to their parents,]] and is perfectly willing to forgive him and stay with him]]. All this hints at [[spoiler:the sweet little girl [[BewareTheNiceOnes having a hidden violent side]]]]. Come the normal ending, and [[spoiler:she [[CurbStompBattle effortlessly defeats]] [[BigBadEnsemble Shinya, King mogeko, and Moge-ko]], then [[KlingonPromotion usurps power]] and [[ProtagonistJourneyToVillain becomes the new Mogeko leader — and will presumably be]] [[RogueProtagonist the sequel's villain]] and an ''[[EvilerThanThou even worse tyrant]]'' than her predecessors! Seems [[AxCrazy Ax-craziness]] [[ItRunsInTheFamily is genetic]] for the Kurai family]].
* FourIsDeath: '''Yon'''aka and '''Shi'''nya. [[spoiler:Relatedly, Shinya just so happens to be an AxCrazy TortureTechnician bent on making Yonaka his next victim.]]
* GagDub: One exists in the form of the fan creation: [[https://www.youtube.com/playlist?list=PLSRV2j8i5ybYsMSrTzNHtm6BXxu3Zo-WH 'Mogeko Castle With Voices,']] by WebVideo/TheWithVoicesProject.
* GratuitousItalian
* HappyPlace: There's vague hints that [[spoiler:at least some of the Happy End may take place in this instead of reality. The choice for it is called the Path to Falsehood, the Bad End you can get as part of it is called Fictitious Truth, and King mogeko makes reference to Yonaka being trapped in a happy dream.]] Nothing's remotely conlusive though.
* HeroicBSOD: Yonaka teeters on the edge of a full breakdown after [[spoiler:Nega-Mogeko's death]], and [[spoiler:remains touch-and-go for the rest of the game]].
* HeroicSacrifice: [[spoiler:Nega-Mogeko makes a LastStand after being shot to give Yonaka time to reach the seventh floor.]]
* InfiniteSupplies: If you can collect an item by inspecting part of the scenery, you can farm that item endlessly if you please. One wonders how a single trash can can hold infinite amounts of garbage, a bookshelf contain infinite amounts of porn, or Moge-ko's drawers contain infinite amounts of her panties.
* KarmaHoudini: [[spoiler:The happy ending has the terrible King mogeko continuing his tormenting of Yonaka. Moge-ko survives in either ending, though the normal ending implies that she serves Yonaka.]]
* KleptomaniacHeroFoundUnderwear: In Moge-ko's room and [[spoiler:Yonaka's room]], you can find their respective underwear. [[spoiler:Although the Kleptomananiac part is subverted in Yonaka's case, as they're her panties.]]
* KlingonPromotion: In one ending, [[spoiler:Yonaka]] takes over the castle by murdering the king, [[spoiler:scalping him, and wearing the top of his head as a hat]].
* LaughingMad: Moge-ko. She tends to giggle madly when she gets excited about killing or torturing someone. [[spoiler:Once Yonaka kills the king in the normal ending, then she also gets a laughing fit.]]
* MortonsFork: Yonaka has to deal with this [[spoiler:near the ending]]: [[spoiler:go back home and face her murderous brother, or return to Mogeko Castle, which is as about as far from a safe haven as you can get]]?
* MultipleEndings:
** Bad End 0: [[spoiler:Everlasting Dream]]: If Yonaka decides not to go into the castle, [[spoiler:a swarm of Mogekos will appear behind her and, after admitting what they know about her, they will gang-rape her, presumably to death (actually, make that "''hopefully'' to death", since [[SexSlave the alternative]] [[FateWorseThanDeath is]] ''[[FateWorseThanDeath considerably]]'' [[FateWorseThanDeath worse]])]].
** Bad End 1: [[spoiler:Assimilation]]: If Yonaka decides to unleash the madness of the first Mad Mogeko, [[spoiler:it will consume her and she will ask many questions about herself, including who she is. She will then "become one with the darkness of Mogeko Castle"; whether this means that she's dead, insane, or something else [[NothingIsScarier is left ambiguous]]]].
** Bad End 2: [[spoiler:Insects]]: [[spoiler:If Yonaka goes in the room with Mogeko larva, she gets swarmed and becomes a host for Mogeko Eggs, which presumably [[FaceFullOfAlienWingWong have been laid inside of Yonaka by the larva]].]]
** Bad End 3: [[spoiler:Meat Party]]: [[spoiler:If Yonaka decides to lift the cage filled with Mad Mogeko, they run towards her and Defect Mogeko and attack them, eating them alive.]]
** Bad End 4: [[spoiler:Toy]]: If Yonaka and Defect Mogeko leave Moge-ko's room instead of going for her bed, [[spoiler:Moge-ko will corner the duo, drag them to her torture chamber, kill Defect Mogeko, and make Yonaka her new toy. She will hang her on one of the many crosses in her torture room and [[ColdBloodedTorture torture (and presumably rape) her for a long time]].[[note]]In earlier versions of the game, Moge-ko just straight-up killed Yonaka. The RPG Maker VX version of the game extended this ending, resulting in the version described above.[[/note]] Her followers will then spy on them during one of their sessions and see the worn-out Yonaka]].
** Bad End 5: [[spoiler:Parasite]]: If Yonaka decides to touch the blancfluff parasite, [[spoiler:it will jump in her mouth and works its way to her stomach. While it's doing that, Yonaka is screaming as it squirms around in her body. Eventually, Yonaka will turn into a Yonafluff]].
** Bad End? 6: [[spoiler:Elopement (Prosciutto Love Affair: Vows on the Sunset Hill)]]: If Yonaka chooses to elope with Defect Mogeko and abandon her quest to return home, [[spoiler:she and Defect Mogeko will run away together and presumably get married. Actually the real happiest ending in the game]].
** Bad End 7: [[spoiler:Fictitious Truth]]: [[spoiler:If Yonaka gets caught by her brother, he will pull out a knife and stab her multiple times while she screams in pain.]]
** Normal End: [[spoiler:Yonaka Castle:]] If Yonaka [[VideogameCrueltyPotential kills any or all of the Special Mogeko]][[note]]including Hasu; he may be dead by the time you get to interact with him, but you can still [[DesecratingTheDead stab his corpse]] for no good reason[[/note]] and [[spoiler:kills her brother, [[KlingonPromotion she will return to Mogeko Castle, knock out Moge-ko, and kill King mogeko. She will scalp King mogeko and wear his scalp like a crown; then, just as the other Mogeko are ready to attack her, she turns into Lord Prosciutto. She renames the castle after herself and decides to use her powers to resurrect her brother, though we don't get to see whether or not she succeeds…]]]]
** Happy End: If Yonaka doesn't kill any special Mogeko and [[spoiler:kills her brother, he will momentarily return to his senses and give her one more smile before passing on. After the credits, King mogeko will be by someone's bedside. He will initially start by talking about happiness. Then, he will reveal that he's by Yonaka's beside and that [[CruelTwistEnding because she is either comatose or on an anti-psychotic/antidepressant medication, she is unable to see or hear him. Meaning, he will continue to haunt her and never leave her alone.]]]]
* MummiesAtTheDinnerTable: One frustrated Mogeko declares that if he can't find Yonaka, he'll blow up the whole castle and sift through the rubble to find her body — "[[ILoveTheDead A corpse is fine, too!]]"
* MythologyGag: The RPG Maker VX remake of the game includes several references to the author's past work, particularly ''VideoGame/TheGrayGarden'', which is an anime in the Mogeko world if the Yosafire figurines and TV broadcast are any indication. [[Videogame/{{Wadanohara}} Wadanohara]] figurines are also seen, and Kurotsuno makes a couple of cameo appearances.
* NotWhatItLooksLike: Averted when Yonaka comes home to find [[spoiler:her parents dead and her brother with a knife]]. "It's exactly what you think."
* OptionalSexualEncounter: Yonaka can "spend a sweet night" with one non-rapey Mogeko. It doesn't have any bearing on the plot; the only difference is that the title of Yonaka's character sheet changes from "Female Student" to "Woman".
* PayEvilUntoEvil: The vast majority of Mogeko are hedonistic rapists, but the game throws some pretty awful things at them. Moge-ko, for one, and even Yonaka herself; [[spoiler:[[VideoGameCrueltyPotential she can run about stealing their precious prosciutto, trap some in a cage to starve to death, and straight-up murder a few]]]].
* PressXToDie: Most of the choices leading to a bad ending are explicitly labeled as such, with the game even outright stating something along the lines of "If you do this, you'll die! [[AreYouSureYouWantToDoThat Do you still want to?]]"
* ProtagonistJourneyToVillain: [[spoiler:Considering that the Gaiden Trailer reveals the Normal End is (seemingly) canon, Yonaka has seemingly usurped King mogeko… only to become a cruel tyrant that surpasses Moge-ko herself. In fact, she's possibly even worse than the King, as she has no fear of asserting herself to Moge-ko and makes it dreadfully clear she's in charge by ''sitting on her.'']]
* PsychopathicManchild:
** King mogeko leads by example. Unfortunately, the example he sets is that of a SpoiledBrat with no sense of morality and a disturbing obsession with high school girls.
** Moge-ko is even more of a SpoiledBrat who treats her Mogeko followers as an endless supply of living 'toys' that [[AxCrazy she enjoys breaking]].
* RedEyesTakeWarning: Yonaka has these on the title screen. Moge-ko also switches between normal black eyes to slit-pupiled red eyes when talking about her cruel intentions or going into a rage. Also seen on [[spoiler:Shinya; they turn black after Yonaka stabs him in the Happy End. Yonaka herself gains these once she's "On the Path to Falsehood" in said ending]].
* RidiculouslyCuteCritter: The Mofuko. Yeah, they have a tragic story, but they're sooooooo cute.
* SelfMadeOrphan: [[spoiler:Shinya kills Yonaka's parents while waiting for her to get back.]]
* SequelHook:
** The Happy End contains a pretty obvious hook, and leads into the trailer for ''Mogeko Castle Gaiden: General Hashasky's Great Adventure''.
** One of the bonus room features is an in-character interview, where the host gleefully mentions that [[spoiler:the sequel's going to take ''EVEN MORE'' from Yonaka]].
* SoundtrackDissonance:
** During a scene where Yonaka is hiding from a Mogeko, cheerful piano music plays while he's crying over his High School Girl Radar being broken.
*** The scene was likely intended to be [[HilarityEnsues humorous,]] so it makes sense.
** The same cheerful piano music plays in Bad End 5 and when Defect Mogeko tries and fails to use a rocket launcher against Moge-ko.
* SplitPersonality:
** Moge-ko might have this. She easily goes back and forth between an almost nice facade to a bloodthirsty monster.
** [[spoiler:This may also be the case for Yonaka's brother, Shinya. While waiting for his sister to return, he tortured, murdered, and mutilated their parents. His red eyes should be proof of this terrifying behavior.]]
* StylisticSuck: The game sometimes uses the sound of a bad-quality [[SyntheticVoiceActor speech synthesis]] for the Mogekos. It may have been deliberately chosen for its creepiness.
* ThousandYardStare: Yonaka develops one when [[spoiler:Nega-Mogeko is shot, and subsequently burnt at the stake]].
* TooDumbToLive: The cause of the bad endings.
* TrademarkFavoriteFood: Prosciutto. There are a few other foods mentioned, like peppers and sea-salt chips, but this is the primary obsession of the Mogekos, to the point that they have an entire religion revolving around it.
* VideogameCrueltyPotential: Yonaka can steal prosciutto from a few Mogekos and leave them in tears, [[spoiler:destroy a switch trapping some in a cage forever to starve to death, and kill quite a few of them. None of these Mogekos do anything to hurt her — she can even kill the ones that ''[[UngratefulBastard helped]]'' her!]]
* YouCantFightFate: King mogeko taunts Yonaka and Defect Mogeko by claiming they can't escape the castle no matter how hard they try, and should just give up and submit already. [[spoiler:[[DownerEnding And he's right.]]]]
* ZergRush: Individually, your average Mogeko isn't very strong, and can easily be dispatched by, say… a knife to the face. However, they have a tendency to swarm, and in the various {{Escape Sequence}}s, Yonaka has to keep ahead of ''hordes'' of the little yellow beasts.
