History VisualNovel / AoiShiro

''Aoi Shiro'' (''アオイシロ''), officially known as ''Blue Castle'' in English, is a supernatural GirlsLove mystery visual novel created in 2008, that takes place within the same universe as ''VisualNovel/AkaiIto'', also made by Creator/{{Success}}.

* HideYourLesbians: Despite advertising and playing up its GirlsLove, the game plays itself fairly coy regarding any relationship confirmation. Yasumi's feelings for Syouko are blatant, and all of the main characters have ''some'' suggestive interactions with Syouko, but the closest Syouko ever approaches to romantic attraction is [[spoiler:with Kohaku]] of all people!

* WholesomeCrossDresser: Kohaku ([[spoiler:who in her previous life was a double for her brother]]). Though not quite a {{Bifauxnen}}, there were some who (prior to the release of the game) were unsure about her. Considering the kind of [[GirlsLove game it is]], though.

-->--'''Opening Narration'''

Originally for the UsefulNotes/PlayStation2, ''Aoi Shiro'' was eventually ported to the PC in 2009.

* AllMythsAreTrue: ...but don't necessarily matter.

* BittersweetEnding - In one of Yasumi's bad ends, [[spoiler:Yasumi decides to [[HeroicSacrifice jump into the Gate with the <<Sword>> in order to close it]]... and to her complete shock, Syouko jumps in after her, embracing her as the glow of the Gate surrounds them]]. Her bad ends are actually pretty sweet compared to [[TearJerker her normal ends]].

* CuteLittleFangs: Kohaku, Kaya.

* FoodPorn: Every. Single. Meal.

* HighlyVisibleNinja: Lampshaded by Syouko in Migiwa's route.

* IntimateHealing - Blood is power, and there are some suggestive ways of extracting it, from [[spoiler:Yasumi's naked out of body vampire sessions]] to [[spoiler:Kohaku preferring Syouko's breasts to her neck]]. Even better is when [[spoiler:[[TwinThreesomeFantasy Nami and naked-ghost-Yasumi]]]] do this at the same time.

* KissingCousins: [[spoiler:Syouko and Kaya, a.k.a. 'Natsu-neesan']]

* MsFanservice: While ''Aoi Shiro'' is a rather tame game and Kaya is much much more than a pair of walking breasts, she never does learn how to button her shirt properly. At the end of Migiwa's route, she even fights Migiwa topless, with only a convenient miasma floating over certain areas.

* MultipleEndings: Fifty-six of them, in fact! Each route has one Happy End where you resolve the conflict, Normal Ends where Syouko survives, and Bad Ends where Syouko dies. (The normal "[[ExactlyWhatItSaysOnTheTin Possessed by the <<Sword>>]]" end in Kaya's route is the odd exception; every ''other'' time Syouko is irrevocably possessed, it counts as a bad end.) Completing all of the other routes unlocks the Grand Route, where all of the characters team up.

* OurVampiresAreDifferent: Not even real Vampires, but blood-sucking Oni.
* OutOfClothesExperience - [[spoiler:Yasumi, quite frequently.]]

* ReallySevenHundredYearsOld: [[spoiler:Kohaku, Yasuhime, and Nami]]

* SaveScumming: Due to the massive number of bad ends.
* SayMyName: ROURYUU! ROURYUU! BA ROURYUU!

* SceneryPorn: The CG is undeniably gorgeous. What takes the cake, is the Blue Castle. A stunning Lapis, almost EldritchLocation. The time you first see it in the Grand Route will take your breath away. By all means a beautiful game, that's on par with most high budget animes. However...
** SceneryGorn:..as is the fountains of blood, countless deaths of your character, decapitations, and [[spoiler: Eldritch horrors ]]

* SexySoakedShirt: Sexy scene in wet kimono.
* SingleStrokeBattle: Munetsugu is fond of this.

* TalkingIsAFreeAction: During Kaya/Munetsugu's final fight in Kaya's route.

* ThemeMusicPowerUp: [[spoiler:Not a guarantee for a non-Bad Ending...]]

Like it's sister-game, Aoishiro is known for it's scenic atmosphere centered around the pure blue depths of the ocean, and challenging NintendoHard "gameplay".

* LighterAndSofter: While having more "bad endings" then Akai Ito, it's , quote on quote, so called "Good endings" are severely less depressing then Akai Ito's. Though the Normal Ones are just as sad. And the mood of the game is overall less dark. (Shown in it's Motiff. Akai Ito's is Blood, while Aoi Shiro's is water.)

* ArtifactOfDoom: <<Sword>> drives the people who wield it insane. [[spoiler: Which is the fate of Osa in many endings.]]* AxCrazy: The result of using too much power from the cursed sword.

* SenpaiKohai: Syouko and Ayashiro are sempai to Momoko and Yasumi; both are also greatly admired.

* LaserGuidedAmnesia: Syouko has a case of this; she doesn't have many memories of her childhood due to a terrible accident when she was younger. [[spoiler: As it turns out, that "accident" turns out to be ''getting her head partially chopped off''.

* BareYourMidriff: Kaya and her one button; also see Underboobs below. Also Migiwa.

* SempaiKohai: Syouko and Ayashiro are sempai to Momoko and Yasumi; both are also greatly admired.

On September 14, 2022, a Remastered "HD" version of the game was announced for the Nintendo Switch and, alongside it's older "sister-game" Akai Ito, at the Tokyo Game Show,, with a release date planned for 2023. In addition, this
version would receive an official English language option for the very first time, and be given a release outside Japan.

** The upcoming HD remaster, which is not only upscaling the visuals, it's being released with an official language ''English'' option.

* ForgottenChildhoodFriend: [[[spoiler:Yasumi ''and'' Nami end up being this. Osa will confirm either them to the ones in her memories in each of there route, only for it to be confirmed it's ''both'' of them in different memories in the Grand Route.]]]]

She loved meeting new people…She would say, those raised under a high ceiling will grow taller—and seeing the world makes a person bigger.
