History Manga / ZekkyouGakkyuu

''Zekkyou Gakkyuu (Screaming Lessons)'' is a {{Shoujo}} [[GenreAnthology Horror Anthology]] created by Ishikawa Emi.

** ''Hell's Clock'' [[ZigzaggedTrope zig-zags]] one way and another.

* DaylightHorror: Majority of the stories take place during the day.
* DeadAllAlong: ''The Ocean Is Calling'' [[spoiler:zig-zags the trope all over the place]].
* DeadPersonConversation: Anytime Yomi is actually an appearing character in the story, it turns into this.

* DeadlyPrank: A favorite tactic of a victimized or jerkish Protagonist. Usually results in their death, and sometimes others.
** ''The Devil's Game'' has one, sort of. [[spoiler:Mio's character encounters a murderer in-game and realizes she's in danger in real life, too. She hides in the bathroom, but realizes that she's cornered and the murderer is closing in. Mio then chooses to erase her save file, hoping to save her, just as the door opens... and reveals her friends having dressed up creepily to scare her. Too late, Mio has already erased herself from existence.]]

** ''Hell's Clock'' has the titular clock being given by the school ghost, if you ask her for it. In exchange for using the clock, she takes your most treasured thing away. [[spoiler:Rui ends up losing Kei in a car accident when she first uses the clock. The second time she uses it, she chooses to try to kill herself to keep him safe, but Yomi was so touched by her earnest demeanor that she merely took five years of 'her future'.]]

* TooDumbToLive: Izumi, the protagonist from ''The Red Thread'' tries to prove to a love rival that her crush really do reciprocate her feelings by jumping off the school roof, believing that her beloved would come to her rescue. This is stupid on so many levels since: 1) her crush have no way of knowing that she's going to jump, since she's doing it on pure whim, and 2) he'd have to somehow be close enough to her proximity to be able to save her, which is unlikely. [[spoiler:By [[ContrivedCoincidence happenstance]], her crush does happen to be nearby. But since he doesn't actually like her back, he fails to notice her fall.]]

* AdultFear

* AndIMustScream

* BreakTheCutie[=/=]BreakTheHaughty: Depending on what side the protagonist is on, she will be the cutie to be broken or a haughty facing her come-uppance. There's also generally a secondary character, playing the other side.

* ImAHumanitarian

Despite the series being published in a magazine for preteens and older (''Ribon''), a large portion of the stories are surprisingly dark and terrifying. Cruel twists and terrible fates are the norm, though some stories became a bit more lighthearted over time.

* ''Friend of the Science Room'' doesn't show the [[spoiler:skeleton tearing apart its victims]].
* ''Beloved Plush Toy'' only shows Kurumi [[spoiler:being confronted by her angry stuffed animals]].
* ''The Tale of Twins'' cuts away just as [[spoiler:Nana]] gets confronted by a knife-wielding classmate.

* {{Adorkable}}: Yomi, as well as [[RuleSixtyThree Yumi]].

* GoryDiscretionShot

** ''The Witch of the Library Room'' does this for [[spoiler:Riri's death]]. All that's shown is blood seeping out from under the bookcases.

* DeadlyPrank: ''The Devil's Game'' has one, sort of. [[spoiler:Mio's character encounters a murderer in-game and realizes she's in danger in real life, too. She hides in the bathroom, but realizes that she's cornered and the murderer is closing in. Mio then chooses to erase her save file, hoping to save her, just as the door opens... and reveals her friends having dressed up creepily to scare her. Too late, Mio has already erased herself from existence.]]

** ''Black Cat Saya'' implies that she eventually took to eating humans.

** ''Graduate Number 108:'' Rina and her friends are going to graduate from elementary school soon, but see a strange shadow around Rina in all the pictures from the yearbook. The shadow gets closer and clearer with each viewing of the pictures. Rina figures it must be the spirit of Reiko, a girl that went missing during the previous summer. [[spoiler:It turns out that Rina is a bully and puts herself into the spotlight, something that Reiko is well-aware of and called her out on it. In a fit of rage, Rina killed Reiko and burned the body in the incinerator. When she's about to do the same to the yearbook and gloats about how she'll continue to bully herself friends in middle school and highschool, Reiko pops up and drags Rina into the incinerator.]]

All stories begin with a narration by a strange girl, who is eventually revealed to be called Yomi, talking about an event that will become the focus of the current story. She also gives another narration at the end, mentioning the {{Aesop}} of the story and warning the reader that they could end up trapped in the same situation as the protagonist has just been in.

** ''Bloody Valentine'' shows Misaki [[spoiler:being confronted as the delusional yandere she is and, refusing to let reality set in, attack her crush and his girlfriend with a stone]] and the sounds of an ambulance approaching. The epilogue shows that Naoyuki is in the hospital, but his condition is stable and he'll be released soon. We hear that the girl who attacked him was institutionalized and his girlfriend is coming to visit him. [[spoiler:The silhouette at the door is Misaki, who managed to frame the actual girlfriend into being locked away, and has gotten off scott-free herself.]] Naoyuki's horrified face says it all.

* TooDumbToLive: Izumi, the protagonist from ''The Red Thread'' tries to prove to a love rival that her crush really do reciprocate her feelings by jumping off the school roof, believing that her beloved would come to her rescue. This is stupid on so many levels since: 1) her crush have no way of knowing that she's going to jump, since she's doing in on pure whim, and 2) he'd have to somehow be close enough to her proximity to be able to save her.

* IdiosyncraticEpisodeNaming: All chapters are called Periods.

* IdenticalTwinMistake: ''The Story About Twins'' has Nono and Nana constantly be mistaken for the other on mere sight. [[FridgeLogic Despite them having different haircolors]].

* {{Backstory}}

* SuperIntelligence: ''Supplements for the Brain'' features a pill that increase a person's latent intelligence, as long as they make sure to only take one pill a day.

* LighterAndSofter: Later chapters have eased up on the gore or body horror, as well as getting some happier endings to them. Likely changed due to the series being published in ''Ribon'', a magazine aimed at preteen girls and parents found it a bit ''too'' dark.

This series is complete at 20 volumes. A sequel series with new stories, labelled ''Zekkyou Gakkyuu Tensei'', debuted in summer 2015.

** ''The Slit-Mouthed Woman'' has one of Miya's friend mention ''The Girl Under the Bed'' as a story she mentioned last time. Someone asks Endou if he heard the story, who replies, "[[LeaningOnTheFourthWall I think it was in a manga]]".

* AfterlifeExpress: The titular bus in ''The Bus To The Underworld''. Anyone can board the bus, even if it is not their time yet, as Miku notices. [[spoiler:She refused to get off the bus when it arrived at its destination, leading to her waking up in her home and learning that she fainted at the bus stop and was in a coma for the past three days.]]

** ''An Endless Game Of Tag:'' Hiroko was bullied and mocked for being bad at playing tag back in 1st Grade, leading to her staying behind after school and practicing running, until she was hit by a car. And with a rumor of a monster appearing in people's dreams that forces them into a terrifying game of tag, it's believed that the deceased Hiroko's spirit may be behind it. Since [[JerkJock Chika]] is the best when it comes to playing tag, she's not worried when the time comes for her to have the nightmare. [[spoiler:Unfortunately, Chika gets caught. Years pass and it's revealed that Hiroko didn't die during the accident, but has been in a coma since. And so has Chika by now, with both of them stuck in nightmares, playing tag.]]

* ArtisticLicenseBiology: ''The Land Of Mermaids'' has Nana get a lot of plastic surgery done and she's seen shortly after, now with a bigger bust, different face and long hair and looking beautiful like a doll. It's common knowledge that a person is not beautiful after getting surgery done, due to swelling and bruising. Realistically, Nana would require a few weeks to look that good after getting so much done.

** ''The Birth Of Yomi'' expands by serving as an interim between the above and Yomi's role as a narrator. [[spoiler:Yumi's spirit haunted the old home-ec room of the school. When some bullies decide to rip off the protective charms from a nearby shrine, the unleashed spirit was going to devour the bullies and other students. Yumi sealed the spirit inside of herself and gained her [[ExoticEyeDesigns unusual eyes]] and apparent joy for horror.]]

* BeautyIsBad: In some stories, the beautiful and well liked people are actually selfish and cruel on the inside. ''The Bonds Of A Curse'' makes it clear that, while [[spoiler:Sakahara-senpai]] is quite good-looking, the person's character is anything but pleasant. On the opposite end, [[spoiler:Kurosawa]] is described as gloomy, but turns out to be wonderful.

* BrokenAesop: ''The Bonds Of A Curse'' has Yomi tack on a moral about how killing is wrong, though this is one of the few early stories that had a genuinely happy ending. [[spoiler:Ai and her new friend, Kurosawa, face no consequences for cursing Sakahara. While Sakahara died, he was an [[AssholeVictim utter jerk]] who deserved to die for torturing a helpless puppy to death. And Ai and Kurosawa are moving on with their lives, now that the puppy has been avenged.]] The more obvious and better-supported Aesop for the story would have been the typical [[FaceOfAnAngelMindOfADemon don't judge a book by its cover]].

* ChainOfPeople: A horrifying variant is used in ''The Land Of Mermaids''.

* CloseKnitCommunity: ''The Friendly Apartment Complex'' is a perfect example. The residents take care of each other, the adults and older children tutor the younger ones and they have a vegetable garden where they grow all their food, so there's no need to head out and buy any groceries. And they get strangely obsessive over any neighbor in the complex that wants to go outside.

** ''The Slit-Mouthed Woman'' has one of Miya's friend mention ''The Girl Under The Bed'' as a story she mentioned last time. Someone asks Endou if he heard the story, who replies, "[[LeaningOnTheFourthWall I think it was in a manga]]".
* CozyCatastrophe: The epilogue to ''The Boyfriend Lesson'' reveals that [[spoiler:virtual humans have replaced the majority of humanity and the [[ChildlessDystopia birth rate is at zero]]. Why bother going to the trouble of finding a partner and raising offspring, if one can simply create the ''perfect'' one with a few clicks? And the [=AIs=] are so pleasant to be around that]] even the Prime Minister's response is to 'let nature take its course'.

** The entire doll collection in ''The House Of Dolls'' counts. [[spoiler:They are made of the skin and clothes fabric of real people.]]

** ''Guardians Of The Mountain'' has the elderly couple ask people to be on their best behavior while camping there. And if one happens to litter or pee into the river [[spoiler:they'll be killed, cooked into a stew and served to the next batch of campers]].

** The two-parter ''The Day I Became A Demon'' has Kana stand up for Erika and ends up getting bullied, with [[UngratefulBastard Erika]] joining the bullies herself. When Kana travels back in time, she chooses to side with the bullies this time and picks on Erika. Including locking Erika into a burning room. [[spoiler:And Kana only goes back when she realizes that Erika's wish caused time to revert itself because she felt horrible over bullying Kana.]]

* DoesThisRemindYouOfAnything: One story was just a big metaphor for female puberty. In the hopes of being treated more like a girl, the {{Tomboy}} heroine gets a flower stuck to her head. When it blooms, she's got all the attention she wanted from boys and girls alike, but as the flower gets bigger and bigger the boys get more desperate for her nectar. The metaphor is hammered in at the end, when the resident SchoolIdol (who also has a flower) looks at the heroine's corpse and mocks her for trying to grow it so quickly instead of letting it bloom over time.
* TheDollEpisode: ''The House Of Dolls''; ''Mary's Dining Table'' and ''At Emily-chan's House''.

* EvilDetectingDog: Kotaro from ''The Bonds Of A Curse''.

* TheFakeCutie: Moeno from ''The Last White Day'' looks sweet on the outside to boys, but in reality is only nice to them to get tons of return gifts when White Day rolls around.

** ''Best Friends Chocolate:'' [[spoiler:Mari appears to abandon her friend when she gets stalked by Chiyoko-san, a loner that is said to kidnap anyone she gives her cursed chocolate to. It turns out that Mari merely pretended to do so because she was working with the teachers to catch Chiyoko-san and save Hina. Unfortunately, Hina only learns of this after pushing Mari down some stairs and moments before Chiyoko-san kidnaps her.]]

** ''Boys And Girls'', with similarly bad results.

* GenderBlenderName: ''Boys And Girls'' has Yuuki, who is a girl or boy, depending on the universe.
* GenderFlip: ''Boys And Girls'' has alternate universes be this, with the female Yuuki being a boy in a different universe. The final page also shows a gender-flipped Yomi.

** ''The Witch Of The Library'' does this for [[spoiler:Riri's death]]. All that's shown is blood seeping out from under the bookcases.
** ''Boys and Girls'' has the scene cut away and return just as Yuuki [[spoiler:beats up all the boys who bullied her with a chair, with their bodies bloodied and piled over each other in the aftermath]].
* GrassIsGreener: Yuuki hates being her gender and only sees the bad in it, so she wishes to become a boy instead. Little did she realize that being a boy comes with its own problems, and that her situation didn't change at all just because she's free of feminine worries. [[spoiler:Her male counterpart evidently goes through the same thing in her body.]]

* GrowsOnTrees: ''The Money-Tree'' is a special bonsai tree that has ''yen bills'' as its harvest!

** ''Best Friends Chocolate'' shows Mari receiving Chiyoko-san's chocolate.
** The end of ''Marionette Lover'' has Aki stuck in the same position he was in at the beginning: with a super possessive girlfriend who really cares about her own happiness. [[spoiler:Except it's Junko this time, not Nishino, and at the very least Aki's caught on early.]]

** ''Guardians Of The Mountain'' has [[spoiler:the elderly couple]] killing and eating people [[spoiler:that don't respect the mountain's nature. And they feed that food to the other campers]].

* IrritationIsTheSincerestFormOfFlattery: ''The Matching Classroom'' starts off this way before getting creepy.

** ''The Bonds Of A Curse'' has Kotaro, a sweet little puppy that a class is taking care of and Ai loves him to death. Even Kurosawa, the weird loner girl, seems to like the puppy. Kotaro is found dead one morning and Ai learns that [[spoiler:the popular Sakihara-senpai has been using the dog as a stress-reliever by putting a rope around its neck, tieing it to his bike and dragging the dog along]]. In response to that, Ai asks Kurosawa about cursed voodoo dolls she's rumored to have power with. [[spoiler:Last we hear, Sakihara's clothes got stuck to a truck and he was dragged to death.]]

** ''Supplements For The Brain:'' Ayumi just cannot get any good grades when it comes to math. Even at cram school, she's put into the lowest class and can barely keep up a good average. She finds an ad for pills that make someone smarter and orders them, with the instructions insisting on only taking one pill per day. The pills work! Ayumi's grades improve and she gets put into the best class with her friend, Megu. But she overhears how Megu and other girls talk how Ayumi's sudden improvement is strange and she must be cheating. In her anger, Ayumi takes a handful of pills and, when she surpasses her friend in the next test, rubs it in Megu's face. [[spoiler:When she comes home, the pill company reprimand her for having taken more than the recommended dosage and she will be collected today, so that they can perform tests on her brain. Ayumi hides in terror and gets a message from Megu, who apologizes for talking badly about her friend and admits that it was because she was envious. She struggled to get good grades, while Ayumi made it look so effortless. Realizing how wrong she was about her friend, Ayumi breaks down as the people from the company arrive to pick her up.]]

** ''The Girl Under The Bed:'' The story of a girl hiding herself under the bed of traitors before killing them gives Yukina the idea of playing a prank on her friends. She hides under the bed to scare them, but instead overhears how her friends say they really don't like Yukina and wish she'd leave them alone. Unable to let go of this betrayal, Yukina begins to play more and more pranks on the girls to scare them and punish them for just pretending to be friends. [[spoiler:It turns out that Yukina's friends knew all along it was her and tell her to leave them alone. In the end, the titular girl under the bed appears under ''Yukina's'' bed for being the real traitor amongst friends.]]

** ''The Day I Became A Demon'' has Kana plan to do this to Erika. [[spoiler:Averted, when Kana comes to Erika's rescue.]]
* LackOfEmpathy: Most of the monsters. Some are justified in their actions, since they are looking to get revenge on those who wronged them [[note]]''Slit-Mouthed Woman'' and ''Graduate Number 108''[[/note]] and others simply have no human morals or don't understand how their actions are wrong. [[note]]''Best Friend''[[/note]]
