[[caption-width-right:250: Hauntings: More awkward than you'd think.]]

''Tasogare Otome x Amnesia'' (aka ''Dusk Maiden of Amnesia'') is a [[GenreBusting tragedy/horror/supernatural/shounen/mystery/romance/ecchi]] manga by Maybe (and yes, that's the creator's [[OnlyOneName name]]).

Kanoe Yuuko has been a ghost in the OldSchoolBuilding for a long time without being able to make contact with the living, until first-year junior high student Niiya Teiichi came along. Now they try to solve the mysterious circumstances under which Yuuko died, hindered by the fact there are at least ''seven'' different ghost stories about the school, some of which are possibly based on distorted accounts of her death.

An [[AnimatedAdaptation anime adaptation]] by Creator/SilverLink aired as part of the Spring2012AnimeSeason.

----
!!Examples:
* ACupAngst: Kirie is jealous of Yuuko in this regard.
* AdaptationDistillation: The anime cut out a number of elements, such as Okonogi being a year older and a member of the newspaper club.
* AdaptationDyeJob: Yuuko and Kirie have normal black hair in the manga while the anime gives them relatively dark/muted purplish and green-bluish hair respectively.
* TheAloner: For nearly 50 years, Yuuko has wandered the labyrinthine school where she died. Though she can still interact with physical objects, she's often completely unseen by other people; she can still try talking to them, but they only register her voice as coming from 'someone over there'. People who ''do'' catch glimpses of her are quickly frightened off by [[ClapYourHandsIfYouBelieve the horrifying apparition they expect to see in a 'haunted school',]] further alienating her from the world. It's a miracle she hadn't broken down after all that time... [[spoiler:though later chapters reveal that her ghostly coping mechanism is a bit... [[ShadowArchetype extreme.]]]]
* ArtShift: A few. Chapter 18 has a sudden one, while Chapter 21 has several panels containing little more than rough outlines. Whether these are due to a [[CreatorBreakdown creator breakdown]], [[DeusExMachina deus ex machina]], [[ExecutiveMeddling executive meddling]] or the [[http://en.wikipedia.org/wiki/2011_Sendai_earthquake_and_tsunami 2011 Sendai Earthquake]] is as of yet unknown.
* [[spoiler: [[BackFromTheDead Back From The Afterlife]]: Yuuko returns due to Teiichi's efforts.]]
* BarbieDollAnatomy: Played straight often, since we see Yuuko (and occasionally one of the other girls) at least partially nude every few chapters.
* {{Bishonen}}: Teiichi. Most obvious during the times he (reluctantly) cross dressed.
* BleachedUnderpants: Explains the Fanservice. Also, two minor characters from the early chapters are from one of Maybe's hentai stories.
* BoyMeetsGhoul: Teiichi and Yuuko sitting in a tree, K-I-S-S-I-N-G...
* BreakTheCutie: Yuuko's past. [[spoiler: Was killed by other villagers and her own beloved sister by having her leg broken and thrown into a basement to slowly die.]]
** [[spoiler: Yukariko also suffered from this event. She sacrified her sister because she was most important to her and authentically believed that it was the way to cure the plague. Problem was that it didn't. Everyone around her died and her father committed suicide over Yuuko's death. The cherry on top was seeing Yuuko's shadow ghost and having it try to kill her. When it chose to spare her, she took it to mean that Yuuko wanted her to suffer by living. For the rest of her life, she'd continue to be haunted by her sins since she only ever saw Yuuko's shadow, and never the other part of her.]]
* [[CaughtTheHeartOnHisSleeve Caught The Heart On Her Sleeve]]: When Yuuko decides to walk out of Teiichi's life, this is his response.
* CerebusSyndrome: [[spoiler: Shadow Yuuko]] sucker-punches the manga's comedic slice-of-life nature with a tire-iron, especially [[spoiler: when Yuuko's true past is revealed.]]
* ChekhovsGun: Akahito-san. [[spoiler: Turns out Akahito-san is the name of the emissary of the mountain god Yuuko was sacrificed to appease.]]
* ChickMagnet: Teiichi, who has three different women pining after him.
* ClapYourHandsIfYouBelieve: To most people, ghosts are only visible if they already believe there's going to be something there, and then they usually see some ghastly specter in line with their fears rather than the real ghost. [[spoiler: Also applies to those who can see a ghost already, as their perception of the ghost can be changed by making them believe the ghost truly looks different.]]
* {{Cloudcuckoolander}}: Momoe.
* ClingyJealousGirl: Yuuko can get jealous of Momoe's crush on Teiichi.
* CreepyBasement: The underground shrine has all the qualities of this, with a bonus corpse.
* CrossdressingVoices: Creator/JunkoMinagawa as Teiichi in the drama CD.
* CruelAndUnusualDeath: [[spoiler: Yuuko's death. Because of superstitious rumors, several adults (and her own beloved little sister) sacrificed her to village god. By entrapping her in a dark CreepyBasement and breaking her leg so that she couldn't escape, so she would end up dying very slowly and painfully in there.]]
* CryCute: Kirie is prone to this when she's scared.
* CurtainsMatchTheWindow: Teiichi and Momoe (in the manga; the anime gave her green eyes).
* CuteGhostGirl: Yuuko is downright adorable.
* DancingTheme: In an interesting subversion Yuuko does a [[http://en.wikipedia.org/wiki/Bon_dance Bon Dance]] in the [[https://www.youtube.com/watch?v=uZ-pG5BUGnQ opening.]]
* DeadpanSnarker: Kirie, and Teiichi has shades of it.
* DeathGlare: When Yuuko was [[spoiler:an onryo, she was constantly glaring]].
* DisguisedInDrag / SweetPollyOliver: Teiichi and Kirie switch clothes in one of the extra chapters.
* [[DyingDeclarationOfLove Dying Declaration of Hate]]: Yuuko dies while swearing revenge on [[spoiler:Yukariko and the others who sacrificed her.]]
* EmotionlessGirl: [[spoiler: Yuuko was one prior to meeting Teiichi, as she had cast aside [[ThePowerOfHate the one emotion that kept her rooted in the world of the living]].]]
* [[spoiler:EnemyWithout: Shadow Yuuko.]]
* EvolvingCredits: At the end of Episode 7, as the closing song plays, Yuuko [[spoiler: is no longer visible performing the song.]]
* {{Expy}}: Yuuko. Long hime cut? Red eyes? Acts either mysterious or mischievous? Likes making one specific boy really uncomfortable? Yeah, sounds a lot like [[XxxHOLiC a certain Witch of Dimensions.]]
* {{Fanservice}}: Yuuko, my god. And it's surprising, seeing as there are few to no panty-flashes, the fanservice often being done with Yuuko fully dressed.
** FanDisservice: [[spoiler: As mentioned below, Corpse-Yuuko. Still in a towel.]]
* FateWorseThanDeath: See BreakTheCutie.
* FreezeFrameBonus: The observant will see the screen flicker twice during the 1st trailer. [[spoiler: Pausing it reveals [[http://images1.wikia.nocookie.net/__cb20111222173818/tasogare-otome/images/8/8e/Shadow.png this horrifying image of shadow Yuuko]].]]
* FirstKiss: Yuuko and Teiichi have theirs in Chapter 18.
* FunbagAirbag: Teiichi accidentally falls face-first into Yuuko's breasts in the special "Shower Room of Fresh Blood" chapter. He gets a {{nosebleed}} from it.
* GenkiGirl: Momoe, and Yuuko from time to time.
* GenreBusting: Horror + Romance + Mystery + Highschool comedy, to name a few.
* GlamourFailure: In the chapter where Kirie first appears, she tries to convince Teiichi to stop seeing Yuuko as a beautiful ghost girl and recognize her as an evil spirit/monster intent on destroying him. Soon after, [[spoiler: Yuuko loses her regular appearance and appears as a rotting corpse for a while, until Teiichi renews his faith in her and she goes back to being beautiful, voluptuous ... oh, and naked]].
* TheGlassesComeOff: [[spoiler:Kirishima Yuuko originally wore glasses, but stopped wearing them once she decided to get revenge against her bullies and destroy the ghost stories of the school.]]
* GhostAmnesia: The whole plot is built around this. [[spoiler:The shadow Yuuko is literally the spectral incarnation of Yuuko's cast-off memories.]]
* GirlishPigtails: Sahara, Minato and Kirie in her childhood.
* GhostShipping: Teiichi and Yuuko become a couple.
* GreenEyedMonster: Yuuko is rather upset with Niiya after he returns from summer vacation only to start hanging out with Momoe and Kirie.
* HimeCut: Yuuko keeps her hair like this. [[spoiler: Fitting, as she was a YamatoNadeshiko when she was alive.]]
* [[spoiler: HopelessSuitor: Both [[GenkiGirl Momoe]] and [[{{Tsundere}} Kirie]] have crushes on Niiya, but the OfficialCouple is Yuuko and Niiya.]]
* HumanSacrifice: As the Seven Mysteries come together, Yuuko is revealed to have died this way. [[spoiler: Later chapters reveal she was murdered by ''her own sister'' to stop a plague the villages blamed on a sadistic mountain god and its emissary, Akahito-san.]]
* ImportantHaircut / ExpositoryHairstyleChange: [[spoiler:Kirishima Yuuko started out with long hair kept up in a bun, but after deciding to get revenge, she lets it down. She cuts it short after Kanoe Yuuko and Teiichi save her from becoming a sacrifice.]]
* InnocentFanserviceGirl / ShamelessFanserviceGirl: An odd combination. Yuuko sees no reason for modesty in her ghost form, stripping out of one school uniform to put on another right in front of Teiichi, and not bothered at all when, despite having turned away, he gets a ''good'' look in a mirror. When Teiichi finds her actual corpse, fifty-some years dead, however, it's another story entirely -- she's utterly embarrassed, saying that her bones are as naked as a person can possibly get, begs him to cover the body, and calls him a pervert for not doing so immediately.
** [[spoiler: The reason she has no modesty over her ghostly body is that all of her negative emotions have been dumped onto shadow-Yuuko]].
* ItAmusedMe: Yuuko's reasoning for waking Teiichi up in the middle of the night in Chapter 12.
* JapaneseSchoolClub: Yuuko founds the Paranormal Investigation Club, consisting of herself (as the [[IncrediblyLamePun ghost president]]) and Teiichi. Momoe appears to be a semi-member, despite already being part of the Newspaper Club, and Kirie seems to be reluctantly joining the circle.
* {{Joshikousei}}: Two different varieties of them, in fact! The modern uniform the female students wear and Yuuko's old fashioned one both apply.
* KarmaHoudini: The bullies who [[spoiler: attempted to sacrifice Kirishima Yuuko get away nearly scott-free aside from having the living daylights scared out of them by the actual Yuuko-san.]]
* [[spoiler:LaserGuidedAmnesia: Yuuko can apparently cast off any memories that cause her pain or distress. These coalesce into Shadow Yuuko, who, being forced to take on Yuuko's jealousy for Teichii, decided that this time she was going to take all of Yuuko's memories of Teichii from her as well - ''including'' the happy ones.]]
* MarshmallowHell: Teiichi frequently finds himself having his head buried in Yuuko's chest (which is of course initiated by Yuuko). Initially this was part of Yuuko teasing Teiichi, but as they grow closer it's becoming more romantic (and somewhat heartwarming) in nature.
* MayflyDecemberRomance: Yuuko has been fifteen for something like fifty years. She'll be fifteen for the ''next'' fifty years, unless she moves on, or gets reincarnated, or whatever. Teiichi is twelve. Fifty years from now, while Yuuko is still fifteen, he'll be....
* MeaningfulName: The "Yuu" in "Yuuko" means "Dusk/Evening".
** Also [[http://tvtropes.org/pmwiki/pmwiki.php/Main/Moe Momoe]]. [[IncrediblyLamePun Yeah...]]
* {{Megane}} / {{Meganekko}}: Teiichi, Sahara and [[spoiler:Kirishima Yuuko in the past]].
* MoodWhiplash: All over the place, as the story switches between fanservice and jokes to human sacrifice and evil spirits astoundingly fast.
* TheMourningAfter: [[spoiler: Teiichi adamantly refuses to get over Yuuko after she passes on, going so far as to try to bring her back by spreading the truth about her death and afterlife in the form of a new set of rumors, reasoning that because ''he'' was her final regret she wasn't able to fully pass on. Kirie thinks he's gone insane, but it turns out he's correct.]]
* [[spoiler:MummiesAtTheDinnerTable: Soon after Yuuko's death, Yukariko reopens the shrine and goes down to see her sister's body. She ends up crying and resting with her head in the dead Yuuko's lap.]]
* MyGreatestFailure: [[spoiler:Yukariko considers her part in killing her sister in what would be a SenselessSacrifice and ShootTheShaggyDogStory is this.]]
* NiceJobBreakingItHero: Yukariko [[spoiler: sacrificed her sister in hopes of stopping the plague. [[SenselessSacrifice It didn't work]].]]
* NonhumanLoverReveal: Teiichi doesn't realize Yuuko is a ghost when he first meets her, [[spoiler:though he doesn't fall in love with her until later]].
* {{Nosebleed}}: Teiichi has one [[spoiler:during an intimate moment in the school showers, creating a new school mystery.]]
* NotWhatItLooksLike: Momoe walks in on a situation where Yuuko has fallen on top of Teiichi (she'd put on his glasses for a joke, and they really screwed up her vision and balance) and ''then'' started getting flirtatious. Teiichi promptly yelps that "It's not what it looks like!" ...forgetting that the new girl can't see Yuuko, so it ''didn't'' look like anything naughty to her.
* OneSteveLimit: Averted and justified. Another character named ''Kirishima'' Yuuko eventually appears and the fact that Yuuko is a very common name in Japan is immediately brought up. Sadly, having the same name as the school's infamous Yuuko-san quickly gets some bullies the fodder they need to convince everyone that she has a connection to the ghost of the school and should be ignored at all costs. [[spoiler: This convinces her to take revenge on her tormentors and the ghost stories themselves by tormenting the former and destroying the latter.]] It backfires [[spoiler: when Kirishima's new ghost story ''Akahito-san'' convinces some girls that she should be sacrificed due to her supposed connection to Yuuko-san.]]
* OlderThanTheyLook: Yuuko is old enough to be your grandma, but due to being a ghost, she doesn't visually age, so she still looks and acts like a school girl. However, see also YoungerThanTheyLook below.
* OldSchoolBuilding: The school has been modified a lot over its history, leaving parts that are abandoned and badly neglected. The main characters' clubroom is so decrepit, they are probably breaking every health and safety rule in the book in using it.
* OrdinaryHighSchoolStudent: Teiichi, other than the fact that he can see ghosts when most others can't.
* OvertookTheManga: The first nine episodes are very loyal to the manga, but the anime goes in a somewhat different direction from episode 10 onward. It's a mild example, as it still sticks to the story and characters of the original manga.
* OurGhostsAreDifferent: Apparently other than being invisible or having their appearance affected by those who do see them, ghosts aren't much different from humans in abilities.
** Shadow Yuuko seems to have a few tricks, however.
* PantyShot: Happens often with Momoe and Kirie, but rarely, if ever, with Yuuko (given the length of her skirt).
* PetitePride: Played with. Kirei isn't particularly proud of her small chest, but [[LesYay Momoe thinks rather highly of it.]]
* PleaseKillMeIfItSatisfiesYou: Yukariko practically begs [[spoiler:her sister's ghost to kill her during their first encounter.]]
* ThePowerOfHate: How Yuuko [[spoiler:[[StringyHairedGhostGirl comes back the first time]].]]
** ThePowerOfLove: How she [[spoiler:[[CuteGhostGirl comes back the second time]].]]
* PurpleEyes: Yukariko has these, and her name even has the Japanese character for "purple" in it. [[spoiler:They're a hint to her plot significance as the only remaining survivor of the ritual Yuuko died in and the person responsible for her death.]]
* PsychoticSmirk: At the end of chapter 38, [[spoiler:Yukariko]] wears this alongside HiddenEyes.
** [[spoiler: Shadow Yuuko]] has this down to an artform.
** [[spoiler: Yuuko died with this expression, having sworn to give herself up to hatred and kill everyone involved in her death.]]
* [[RaisedByGrandparents Raised by Grandmother]]: Kirie was raised by her Grandma Yukariko, Yuuko's little sister.
* RapunzelHair: Yuuko-san, Kirishima Yuuko, [[spoiler:Shadow Yuuko, and Yukariko in her youth]] all have very long hair.
* RedEyesTakeWarning: Averted with Yuuko and Kirie, [[spoiler: but played straight with Shadow Yuuko.]]
* SchoolgirlLesbians: ''The Six Year Sakura'' legend revolves around this.
* TheSevenMysteries: This school's seven mysteries are (albeit warped) based on parts of Yuuko's death.
** [[spoiler:It has recently been revealed as of Chapter 33 by Yuuko's still living sister that there are only six mysteries and that the seventh never existed in the first place. [[EpilepticTrees What this means has yet to be revealed.]]]]
* [[spoiler:ShadowArchetype: Shadow Yuuko is explicitly everything Yuuko's repressed and denied about herself, especially any hurtful memories, unconsciously separated from her to spare her the mental suffering.]]
* ShipTease: [[spoiler: Before they finally spit it out]] Yuuko and Teiichi have this a lot. There are also hints of Kirei/Momoe.
* ShootTheShaggyDogStory: Yukariko's flashback and [[spoiler: Shadow]] Yuuko's memories reveal that [[spoiler: Yuuko was sacrificed by her fellow villagers to a malicious god with her own sister acting as the god's priest, Akahito-san, in order to stop a plague ravaging the village. The sacrifice didn't work, and worse, Yuuko returned as a StringyHairedGhostGirl determined to kill those responsible for her murder.]]
* SlasherSmile: [[spoiler:Shadow Yuuko, combined with MoreTeethThanTheOsmondFamily. A large part of ''why'' she's terrifying.]]
* StepfordSmiler: To the others, Yuuko is extraordinarily upbeat and nonchalant about her own death. [[spoiler:She has a good reason for this - all her negative emotions have been piled onto Shadow Yuuko, leaving her with only the positives.]]
* StringyHairedGhostGirl: When she first hears of her, Kirie suspects this of Yuuko, though [[CuteGhostGirl she's actually far from it.]] [[spoiler: Chapter 40 reveals Yuuko really ''was'' once a textbook example of an onryo, having been consumed by rage and hatred towards her village and especially her sister when she died. However, she couldn't bring herself to kill Yukariko, leaving her grudge unfulfilled, and eventually cast aside her negative emotions and memories, which manifested as Shadow Yuuko.]]
** [[spoiler: In Chapter 45.1 they investigate a [[GlasgowGrin Slit-Mouthed Woman]].]]
* ThanksForTheMammary: In the first chapter, Teiichi doesn't quite believe Yuuko is a ghost, so he reaches out to grasp her shoulder, reasoning that a ghost will be insubstantial. That's just when she turns to face him, though, so he gets a handful of '''quite''' substantial breast. Yuuko is totally unfazed by this (see InnocentFanserviceGirl). She even jokes about it. ''"I suppose these tend to be quite the temptation."''
** It wouldn't be the last time, either. While convincing Momoe that he's banishing an evil spirit, Teiichi gets another handful of Yuuko's considerable endowments. And he gets a full on [[MarshmallowHell faceful]] in a manga story when Yuuko insists on using the shower with him.
** [[spoiler: The first manages to be somewhat plot-relevant, as Teiichi brings back Yuuko's memories of him by getting another handful.]]
* ThroughHisStomach: In one of the early chapters, Yuuko is shown feeding Teiichi from a bento. On the next page, she pulls him down onto her LapPillow. He's a bit weirded out by this because Yuuko, although very good-looking and ''[[BuxomIsBetter built]]'', has been dead for something like fifty years.
* TrueSight: Though everyone can see ''something'' of Yuuko if they expect something to be there (often of the horrific sort, which changes how she looks to them), only Teiichi and Kirie can see Yuuko and [[spoiler:the second, cast-off version of Yuuko]] as they really are. [[spoiler:Strangely, Yuuko's sister can see shadow Yuuko, as well, but not the normal Yuuko.]]
* {{Tsundere}}: Kirie.
* TwelveEpisodeAnime
* UncannyFamilyResemblance: Kirie is Yuuko's grandniece. A resemblance, particularly of the eyes, was hinted at as soon as Kirie showed up, but in Chapter 20, she gets put into a long-haired HimeCut wig ... and the resemblance just ''jumps'' right out -- except for her [[ACupAngst figure]] (and the CatGirl ears). It's even noted by Kirie's grandmother, Yukariko, who is Yuuko's younger sister.
* UndignifiedDeath: Yuuko's left leg was broken to the point where the bone was sticking through and then she was tossed down a staircase and left to starve.
* UnresolvedSexualTension: There's so much between Teiichi and Yuuko it's not even funny.
** [[spoiler: They finally confessed their feelings in chapter 18.]]
* WhamEpisode: Episode 7 of the anime brings together a number of plot points that the anime had been skipping over (curse rock, [[spoiler:shadow-Yuuko's identity]], Yuuko's breakdown etc) in one wham-packed episode.
** Chapter 37 reveals that Yuuko was killed by [[spoiler: her own sister]].
* {{Yandere}}: One of the SchoolgirlLesbians featured in chapter 10. Yuuko shows signs whenever Momoe gets too friendly with Teiichi, especially in Chapter 17, although this is partially due to [[spoiler:Shadow Yuuko's influence]].
* YoungerThanTheyLook: Most characters due to the art style.
** Teiichi is twelve years old.
** Momoe is actually older than him, but still barely looks her age at thirteen.
** Yuuko looked older than the fifteen years old she was when she died. As a decades-old ghost who doesn't age, she later [[OlderThanTheyLook inverted]] the trope.
* ZettaiRyouiki: Yuuko on occasions.
