History VisualNovel / Ever17

* TheAgeless: People [[spoiler:infected with the Cure virus]] age five years before [[spoiler:all their cells are replaced with Cure cells]], at which point they stop aging. [[spoiler:Tsugumi is the primary Cure carrier, but eventually Takeshi, You'Haru, Kaburaki and Coco are all infected as well.]]
* AllThereInTheManual: The origins of the Cure Virus, as well as the significance of Tsugumi's friend Julia and Shigezo Morino, is only revealed in ''VisualNovel/Never7'', the first game of the series.

*** Likewise, the Cure virus is known to affect the p53 function on the 17th chromosome.

** Jumping from 12.5 atmospheres to 1 atmosphere is suicide, yet [[spoiler:Takeshi]] manages to do this with no ill effects. Then again, [[spoiler:he was ''told'' this would kill him and it probably would have if he didn't have Cure.]]

* BeneficialDisease: [[spoiler:The only real downside to Cure is that it makes you vulnerable to direct sunlight. Some disease. That said, everybody but Tsugumi wants it or doesn't care either way.]]

* BittersweetEnding: In Tsugumi's ending, [[spoiler:everyone escapes the park and the lab below.]] However, on the way out, [[spoiler:Takeshi has to eject himself down to the ocean floor to get Tsugumi to safety.]] Further, though you don't learn this until the end of the Cure route, [[spoiler:Coco was unknowingly left behind.]]

* ChekhovMIA: You's father disappeared seventeen years ago, but she's still looking for him. [[spoiler:He actually does appear in Coco and Sora's routes, but neither You nor the reader realize that he was the dying researcher except in the Cure route.]]

* ContinuityNod: Several to ''[=Never7=]'', such as [[spoiler:the mentioned characters of Shigezo Morino, the father of Izumi and Kurumi Morino, and Julia, one of the origins of Cure Syndrome.]]

** [[spoiler:Tsugumi's healing factor clues Takeshi in to the fact that she's a Cure carrier even though he's never heard of Cure. Earlier, she also knew a door was too hot to touch and would release clouds of steam if opened, but never explains how she knew. She can't; the only explanation is the truth, which is that she can see heat.]]
** Even more directly, [[spoiler:she doesn't catch Tief Blau, meaning You's suspicions that she's a Cure carrier are confirmed.]]

** People with Cure [[spoiler:pass it along with blood, have enhanced physical abilities, can't stand bright sunlight, can see in the dark and have superhuman healing abilities. Vampirism?]] WordOfGod has stated that this was [[WhatCouldHaveBeen a leftover of an old concept that was rejected.]]

* EmergencyTransformation: Unintentional, though known to be a risk. [[spoiler:A vaccine for Tief Blau is created from Tsugumi's blood, but it also transforms everyone in the first incident into Cure carriers.]]

** May 6th is devoted to this as everyone is infected with Tief Blau. [[spoiler:Ironically, the cure is Cure.]]

* MorningSickness: [[spoiler:This is how Tsugumi began to realize that she was pregnant. Particularly notable in her case, as she has the Cure virus, meaning she ''can't'' normally get sick, meaning something was clearly up.]]

* RedHerring: Several, but two notable ones only applies to Japanese players/those who played ''VisualNovel/{{Never7}}'' first. [[spoiler:WordOfGod says that The Kid having the [[Creator/SoichiroHoshi same voice actor as Takeshi]] was meant to deceive players into thinking Kid was a clone of Takeshi (which was pulled off in ''[=Never7=]''), and the Kid's premonitions and mentions of Cure was also meant to fool players into thinking he had Cure Syndrome.]]

* SelfMutilationDemonstration: In spirit, at least. Since Takeshi won't believe in [[spoiler:her own healing ability despite having healed from a grave wound overnight that left nothing but a thin scar, Tsugumi instead crushes Chami in her hands and then shows that he's still fine. Like her, he has Cure. Somehow.]]

** [[spoiler:Yubiseiharukana had herself cloned and gave birth to herself when she about sixteen.]] Given the reasons this occurred in the first place, the baby's grandmother takes care of it. [[spoiler:When her heart condition is healed by Cure and her own mother dies of Tief Blau, she begins raising You'Aki herself before ceasing to age three years later.]]

* WeakenedByTheLight: [[spoiler:Cure carriers have poor ability to cope with sun and no defenses against cancer, so they have to avoid direct sunlight. However, not all Cure carriers get all the symptoms, so while Tsugumi is the only one shown to have all the positive aspects like longevity, healing and infravision, she's also the only one who has to wear a suit to completely hide her body.]]

* WhatIfTheBabyIsLikeMe: [[spoiler:Tsugumi is worried that her children might be Cure species, and won't be able to grow up like normal children. Luckily, her children end up as [[HalfHumanHybrid Sapiens/Cure hybrids]] who grow up normally, and are immune to the effects of the Cure virus.]]

** Four years ago [[spoiler:from the standpoint of 2017, You]] was diagnosed with [[spoiler:a non genetic heart condition and was told she'd be lucky to make it to graduation.]] That said [[spoiler:while Tief Blau was a disaster for the world that claimed tens of thousands of lives, it led to her contracting Cure, which repaired her heart.]]

* {{Bishonen}}: [[spoiler:Takeshi and Hokuto. At first you wouldn't think Takeshi is, but that's because it's not really him. The real Takeshi is described as being ridiculously good looking.]] On a different note, it's kind of amusing when even a {{bishonen}} trope involves major spoilers.

** May 6th is devoted to this as everyone is infected with Tief Blau. [[spoiler:Ironically, [[JustForPun the cure is Cure.]]]]

** In the prologue, You's line [[GratuitousEnglish "I am You"]] is said JustForPun. Next time, [[spoiler:it's said to You'haru by You'aki, to signify that they are the same person.]]

* NoAntagonist: The charaters try to survive in flooded amusement park which is several days away from colapsing. There are some bad guys mentioned, but their villainy is of-screen and they don't provide direct opposition.

** In the prologue, You's line [[GratuitousEnglish "I am You"]] is said JustForPun. Next time, [[spoiler:it's said to You'haru by You'aki, to signify that they are [[CloningBlues the same person]].]]

* CloningBlues: Inverted. [[spoiler:The You in the Kid's routes (Yubisei''aki''kana) is a clone of the You in Takeshi's routes (Yubisei''haru''kana)]]; however, it is [[spoiler:You'haru]], the person who ''was cloned'', who experiences the most angst over it. The clone doesn't seem to care and is much more concerned with other personal issues.

Two {{DramaCD}}'s were made which act as [[PostscriptSeason supplemental stories]] for what occurs after the game's ending. Fan translations of them have been made.

* DeathBySex: [[spoiler:Takeshi dies shortly after having sex with Tsugumi. Sort of.]]

* AluminumChristmasTrees: Yuubiseiharukana is an actual name; the writers said they just found it in a name dictionary.

* CloningBlues: Inverted. [[spoiler:The You in the Kid's routes (Yubisei''aki''kana) is a clone of the You in Takeshi's routes (Yubisei''haru''kana)]]; however, it is [[spoiler:You'hara]], the person who ''was cloned'', who experiences the most angst over it. The clone doesn't seem to care and is much more concerned with other personal issues.

** When the park begins flooding, in the middle of trying to get Takeshi to evacuate Sora mumbles about something called Tief Blau as if it were the more important problem. There are numerous other hints throughout the game for plot points that may not even come up in the same route.

* RapunzelHair: Tsugumi's hair extends to around her knees.

* YouGottaHaveBlueHair: Coco's is pink. Everyone else's is a reasonable color.

* OverlyLongName: That's why she wants to be called You instead.

** A line that's supposed to be like "Of course I know what a hacker is" became "Naturally, I knows the hacker", which became a minor {{meme|ticMutation}} among the fanbase.

** "All of the sudden"
