Who... are you?Who... am I?Ever17, the second game in the Infinity series, is a Visual Novel made by the now-sorta-defunct studio KID (while bankrupt, key members of the company split off into three companies: Cyberfront, 5pb., and Regista), and is one of the very few visual novels to be officially translated into English (by a company called Hirameki International, now completely defunct). It tells the story of six (or is it five? Or seven?) young people who are trapped in an underwater theme park called LeMU when it unexpectedly springs a leak. They then have 119 hours to find a way to escape before the place implodes and they all die. It's a little like The Poseidon Adventure, if The Poseidon Adventure were set in the future and had sinister German pharmaceutical companies and some interesting uses of quantum physics. So not much like it at all, really.The game has two first-person protagonists, each with their own set of paths. The first is an amnesiac boy known only as the Kid; the second is Takeshi, an ordinary college student. Other major characters include Coco, a fourteen-year-old who looks ten and acts about five; You (it's a nickname, not a pronoun, although it's still pronounced "yuu," and not "yo"), a cheerful and friendly employee of LeMU; Sara, an imaginative girl who is a little obsessed with ninjas; Sora, a calm and mature woman who also works at LeMU; and Tsugumi, an enigmatic and unfriendly girl who seems to want little to do with anyone else.The game is also a huge Mind Screw and possessed of a plot so twisty that any attempt to explain or describe it more thoroughly would, by necessity, involve spoilers. Speaking of which, beware of falling spoilers in the trope examples section; some tropes are big spoilers just by being listed.A manga adaptation (based on the Xbox 360 version of Tsugumi's Route) ran from 2011-2012 (translated chapters).Two DramaCD's were made which act as supplemental stories for what occurs after the game's ending. Fan translations of the plays can be found here and here.See also Never 7, Remember 11 (the other two games in the series),12Riven (a spinoff of sorts that takes place in a similar setting), Code18 (the "official" fourth game in the series, though without any input of the original staff), I/O, Root Double (directed/written by the game's director/main writer), and Nine Hours, Nine Persons, Nine Doors (directed/written by the other main writer), all which have similar themes and setups.Due to the nature of the game, the trope page contains many SPOILERS even after following our usual spoiler policy. If you are the type of reader who is bothered by them, probably you shouldn't look at this page at all before playing the game.
Action Mom: Tsugumi, if "After You've Gone" is to be believed, is pretty decent in a fight.
All There in the Manual: The origins of the Cure Virus, as well as the significance of Tsugumi's friend Julia and Shigezo Morino, is only revealed in Never7, the first game of the series.
Aloof Dark-Haired Girl: Tsugumi is tall with long, dark hair and is highly distanced from the rest of the cast. If nothing else, Takeshi is intrigued enough to follow her around a lot.
Ambiguous Situation: Unlike most of the mysteries, it's never made clear what exactly happened in the game of kick the can.
Arc Number: 17, 34 or other numbers divisible by it.
A few of the times/dates have 17 in them.
The most obvious one, being that the year is 2017. The seventeen-year time gap obviously counts too.
Coco's birthday falls on December 17th, 2002.
BW comes into existence on May 1st, 2034 at 3:17 PM.
17 meters (56 feet) between each floor of LeMU.
17 minutes in the decompression chamber in the prologue.
Takeshi mentions the Ninneko Song 17 when Coco starts calling him Takepyon.
17 seconds for the lights to come on after repairing the generator. In 2017, Tsugumi correctly times this by pressing the switch on Takeshi's count of 17, ending with 0 as the lights come on. In 2034, You/Sara/Kid press the button on Kaburaki's count of 34, and Sara counts 17 as the lights come on.
34 rings in Tsugumi's Jewel Chocolate metaphor to Kid. Like the above example, this is a reference to the 2034 incident being a repeat of 2017, in addition to Tsugumi's hinting that she's figured everything out, and is playing along for both the cause of rescuing Takeshi/Coco, as well as collecting her "rings," being her children Sara and Hokuto.
You's father disappeared 17 years ago, when she was 1 year old.
The password to the system is a haiku, which is 17 syllables long (5-7-5)
The Tief Blau virus is labeled "Tief Blau 2017-Rev.17"
Likewise, the Cure virus is known to affect the p53 function on the 17th chromosome.
Due to her condition, Tsugumi stops aging, making her forever 17, at least physically.
It's even expressed in the game's internal logic: Getting Tsugumi's Good End requires 17 affection points.
Artistic License - Biology: Tsugumi states that after seven years, every cell in the human body has died and been replaced. The neurons in the cerebral cortex are never replaced.
Maintaining the complex at six atmospheres of pressure and expecting people to be comfortable? Including children and elders? They transition over 17 minutes, but still.
Also, if you happen to know both Japanese and German, you will make the connection between Sora and the "Himmel" door before it actually comes up in the story. After all, both Sora and Himmel mean Sky.
Bishōnen: 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.
Bittersweet Ending: The "good endings" that aren't the true final ending, mainly Tsugumi and Sora's endings.
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 among the fanbase.
Whenever someone posts a screencap of that line, a post of "Oh You" may follow.
A more literal example would be near the beginning, where someone in a tanuki suit (which, in the first place, is really a lemur suit) being bitten by a girl who is being bitten by a dog. The dog looks nothing at all like the tanuki, and yet the game calls the dog a "smaller tanuki". And then, mind-bogglingly enough, the game later states the obvious and tells you that it's not a tanuki.
Not to mention all the "find and replace" errors, as in "youth" with "Kid". The result gives us sentences like "Kidere" and "Kidink," instead of "You there" and "You think".
Which is particularly ironic, considering a find-and-replace error is an actual plot point during Kid/You's scenario. This is how You'aki' discovers that mentions of her (grand?)parents were purposefully deleted from LEMMIH.
"Tooling test" was suppose to be "Turing test".
Book Ends: Both the prologue and the epilogue start on a boat, narrated by Takeshi.
Broken Bird: Tsugumi. Twice. You"haru" and Kaburaki have essentially become this by 2034.
Chekhov's Gun: Too many to list. Archimedes principle. The cryogenics function on the pods. The coffee machine. The lemur suit. "Life readings: 6." The broken mirror in the bathroom. Can you swim 100ft? "I am You." You's mom had a robot dog... EVERYTHING is important.
Chick Magnet: Takeshi. Getting the affection of Tsugumi, Sora and You'haru'.
Even Sara falls for him, who answers 'papa' when asked of her ideal boyfriend in the audio CD.
Cloning Blues: The You in the Kid's routes (Yubiseiakikana) is a clone of the You in Takeshi's routes (Yubiseiharukana). Unlike most examples of this trope, however, the one being cloned did it willingly.
Defrosting Ice Queen: Tsugumi. Then she refrosts again, and then defrosts permanently by the True End.
Determinator: Takeshi. The game even states that he's actually probably drowned at this point, and he still gets up and saves the day. After having enough done to him to kill him in about six different ways without eating in over a day because he threw up his last meal after swimming through frigid water and without resting at all. Unless you consider being dead at the bottom of the ocean "rest".
All of the survivors of the 2017 incident probably count. Organizing a 17-year-long scam, using your children as pawns, to trick a hyperdimensional being into retconning history takes some balls.
Diabolus ex Machina: Tsugumi's good end, where she and Takeshi board the remote sub and escape just as IBF collapses around them, cue them talking about the future and the forthcoming happy ending right? Nope, the sub just happens to run out of battery power and starts sinking at the conveniently worst possible moment, necessitating Takeshi's Heroic Sacrifice to save Tsugumi's life, and the Tear JerkerDowner Ending.
Ditzy Genius: Sara is perhaps the silliest character, saying the silliest things (both how she says them and what she says, though a lot of it is lost in the English translation), but she is a genius, especially when it comes to computers. Judging by the flashbacks, her silly personality seems to be due to associating with You. Coco is silly too, but she's a Token Mini-Moe so it's expected.
You seems to be pretty smart too, but most of silliness seems to stem from the fact that she's a Genki Girl.
Downer Ending: Both of Takeshi's endings count, as well as all the bad ends. In Tsugumi's ending, Takeshi makes a last minute Heroic Sacrifice to allow Tsugumi to escape to the shore while he drowns, as she cries for him not to die. In Sora's ending, not only does SHE not escape, but Takeshi is caught in the collapse and everyone but Tsugumi is slowly dying of Tief Blau without any available treatment. Luckily, the true end is NOT a continuation of THIS route.
It can be assumed that in the Sora arc, Tsugumi treated all afflicted persons on on her own, while Takeshi was unconscious. Otherwise he probably would not have been able to get to Sora, let alone survive the sudden decompression. Of course this still qualifies as a Downer Ending by a wide margin.
Given how resistant Tsugumi is to that idea in her own route, and how hostile relations are between her and the rest at the end of the Sora route, that is quite unlikely. Most likely, either this was due to Takeshi being The Determinator, or he had gotten infected whilst in the Jellyfish Gondola.
Then again, it is quite explicitly stated in Tsugumi's arc that Takeshi gets some of Tsugumi's blood in his mouth when they kiss. As this means he's infected with Cure, he quite probably can't even die from the pressure. But even if he survives, if he can't get up, the Downer Ending gets even worse.
Everyone Is Related: Out of the nine (ten if you count BW) main characters in the game, six are related to at least one other person (seven if you want to get technical).
To elaborate: Takeshi, Tsugumi, Hokuto and Sara are all a family; You'aki is and You'haru's daughter and clone; Yoichi (You's father) had a hand in the creation of Sora, and thus she also has some relation to You. There's also Coco "adopting" BW as her older brother (and boyfriend).
On the other hand, in a slight subversion, the game leads the player to believe that there's some relation between Coco and Sara. This is highlighted by the fact that they're the major missing link between Takeshi's routes and Kid's routes, they both appear in the same places, sing the same lullaby, and further promotional and extra art typically shows the two together. Fast-forward to the end and epilogue of the game, and there's neither relation nor any real interaction between the two. The Drama CDs don't have the two interact much either (justified in After You've Gone, given their circumstances).
Expy: Most of the characters' personalities and archetypes are similar to characters from Never7.
You is based off of Yuka.
Tsugumi takes traits from Haruka and Saki.
Sora's personality is very similar to Izumi's.
Both Sara and Coco have traits from Kurumi.
Face Doodling: You and Sara do it to sleeping Takeshi. Kaburaki, who was one of the survivors of the first incident, eventually had it happening to him in the second. He probably knew it was going to happen.
If you chose to hit him, Tsugumi's affection points actually go up.
Go Mad from the Revelation: The Kid has brief moments of mental stress no less than three times when he starts to discover his past. You does this rather comically when she learns part of the Kid's past as well.
Golden Ending: Coco's route, which requires every good route to be completed to be unlocked. Coco and Takeshi survive, everyone is reunited, and all the answers are revealed.
Hidden Eyes: A strange version of this: while we never see either Takeshi or the Kid while playing as them (except in some CGs, but even there they are not fully seen), we see exactly what the other looks like while playing from the opposite perspective. Or so we're lead to believe.
On Tsugumi's face when she proves her Healing Factor by "killing" her pet hamster that has the same condition and then proceeds to lay out her backstory.
Honorary Uncle: A variation. Coco begins to call Takeshi and Tsugumi "father" and "mother." By the end, she's calling Blick Winkel "brother."
Human Popsicle: Takeshi and Coco are both cryogenically frozen in order to avoid dying of Tief Blau.
Idiot Hero: Takeshi, at times. Both routes, actually — Kaburaki does a pretty good job of mimicking it, compared to his original, somewhat low-key personality.
Hokuto/Blick Winkel also have their moments. The most notable is at the end of the final path - my friends are cryogenically frozen at the bottom of the ocean, and have been for 17 years already? Well, let me just grab a stone and jump and sink to the bottom of said ocean, instead of just calmly asking someone for a submarine. You"haru" even calls Hokuto/BW out on it.
Ironic Echo: During his Heroic Sacrifice in the Tsugumi route, Takeshi says "Don't touch me" when Tsugumi tries to stop him, which is what she said early on in their relationship when he tries to stop her from leaving in disgust.
Karmic Death: All of Leiblich's Kick the Dog moments, such as capturing Tsugumi, Hokuto, Sara, and Dr. Tanaka, developing and accidentally releasing Tief Blau, and various experimentation comes to bite them back in the ass as they all contribute to the Japanese branch's eventual shut down at the end of the game.
Lethal Chef: There's a reason Takeshi was designated as the one to cook the chicken sandwiches, as one scene proves. You's, Kid's and Coco's sandwiches apparently don't taste bad, but they end up looking bad. Coco's sandwich in particular has a long list of ingredients that probably don't go well together.
Limited Wardrobe: While "Takeshi" and Tsugumi's clothing being the same in 2034 is justifiable, You"aki" still wears the same casual clothes that her mother did in 2017, despite 17 years having gone by.
The Le MU uniform remaining exactly the same after it being detroyed, rebuilt, and 17 years having passed, is also a stretch.
Lost in Translation: The scene about the deaths of Yukie and Yoichi may throw some people off if they're used to the month/day/year calendar system as opposed to the year/month/day system Japan uses.
Love Makes You Crazy: Both Sora and Tsugumi get steadily more unstable in Sora's route resulting in Tsugumi first half killing and then basically raping Takeshi (ot at least taking advantage of his confusion) on the gondola, followed by Sora having a minor Freak Out and trying to drown Takeshi with the sprinklers.
Love Triangle: Sora, Takeshi and Tsugumi. Obvious in both of his routes but only really problematic in Sora's when both have mild breakdowns because of him, with Tsugumi apparently raping Takeshi on the Gondola after asking him to kill her and Sora's reaction of a mental breakdown through jealousy. The Kid as well, sort of, but his two choices aren't a Broken Bird with a Sugar and Ice Personality and a Tin Man with emotional expression issues.
Though one of them is his sister. Good thing the other one is the "canonical"/True Ending love interest, huh?
All the UST between Sara and the Kid admittedly does disappear instantly after that reveal. But there was more there than in any other route in the game which is mildly disturbing.
Luke, You Are My Father: Hokuto and Sara are actually the son and daughter of Takeshi and Tsugumi, though in a slight subversion, Tsugumi already knew this.
Lyrical Dissonance: Sara's Image Song, "Lullaby of Tears", is a poppy, catchy, obnoxiously cute song about how alone and sad she is and how much she misses her brother.
Making Love in All the Wrong Places: Takeshi and Tsugumi have sex in the Qualle (the jellyfish gondola) in Sora and Coco's routes, and in the IBF sickbay in Tsugumi and Coco's routes.
Morning Sickness: 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.
Mr. Exposition: Sora generally fullfills this role inside LeMU while You"haru" does so at the end of the game for Hokuto/Blickwinkel.
Multiple Endings: An interesting subversion occurs here since the "True End" is actually much, much happier than the so-called "Good Ends".
Older than They Look: Coco. Takeshi thinks to himself how energetic elementary school kids are these days... then is shocked to find out that Coco is a third-year in middle school.
Tsugumi as well. In 2034, all characters except Hokuto, Sara, You'aki and Sora are this. Coco looks 10 then although she's actually 32.
One Degree of Separation: Hokuto and Sara are Tsugumi and Takeshi's children. You'aki is You'haru's clone, and the elder's father helped design Sora and LeMu with Coco's father. You'aki and Hokuto are hooked up at the end. Coco has some sort of strange tie to Blickwinkel, and it's not entirely clear who or what that is. That leaves only Kaburaki as essentially having nothing to do with the rest.
One Steve Limit: Subverted with Takeshi: he shares the same first name as Coco's father, Takeshi Yagami (although their names were spelled with different kanji in the Japanese version).
It probably would had made a lot more sense to pair Kaburaki and You'haru together, considering that they spent 17 years together.
Parental Abandonment: You's father died in an accident when she was young, which lead her to work for LeMU to find out what happened to him. He was blackmailed by Leiblich, who faked his death and forced him to continue working for them, and is found in IBF, where he dies of Tief Blau, but not before talking to You one last time.
Takeshi and Tsugumi also do this to Hokuto and Sara, though given their differentcircumstances, they can hardly be blamed. Not that Hokuto and Sara seem to mind...
The Plan / Batman Gambit: The entire storyline is a massive trick, played by the player perspective, on himself.
Properly Paranoid: Tsugumi. Especially in 2034. At least in 2017 it really was an accident.
Psyyyyychic Powers]: Coco claims to have this (spelled like that too), though the extent of her powers is vague. Her feats, however, include the ability to "borrow" the perspective of beings from "the other side" (the 4th dimension), enabling her to see the past, present, and future of everyone in LeMU (which would explain how she knows everything about what Blick Winkel eventually finds out). She's also able to project herself across time, allowing her to speak directly to Hokuto/Blick Winkel, in addition to actually being able to see the latter when they travel across time. Oh, and she can bend spoons with her mind.
The Drama CD "After You've Gone" takes Coco's telekinetic ability further, as she uses her powers to toss around a man who has restrained Tsugumi, while Coco herself is miles away at school. The feat left her mentally drained, however, and she ended up passing out on her desk as soon as she got back to class, but not before wishing Tsugumi good luck.
There's actually a scene with an extended bit of exposition specifically about the legend of Pygmalion as a thinly veiled allegory for the relationship between Takeshi and Sora. May bea Lampshade Hanging, but probably is not.
Really 700 Years Old: Tsugumi, who stopped aging at seventeen due to her genetic code being rewritten by the Cure virus. By the end of the game, Takeshi, You'haru, Kaburaki and Coco have also become this.
Red Herring: Several, but two notable ones only applies to Japanese players/those who played Never7 first. Word of God says that The Kid having the 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.
The Remnant: Non-military example: In "After You've Gone", Kleinmare, a branch of Leiblich, attempts to continue their activities by luring Tsugumi there, though it backfires in the end.
Rip Van Winkle: Takeshi and Coco, who sleep for 17 years in cryo-sleep, though more the former than the latter (as Coco had access to Blick Winkel's viewpoint. In fact, the story of Rip Van Winkle is discussed by Takeshi, You, and Coco at one point as Foreshadowing.
The scene where Coco is introduced as a third-year in middle school is close to Kurumi introducing herself as a third-year in high school. Both of them are Younger than They Look, and likewise act the same mentally.
The same argument over the name of the card game. Coco/Izumi call it "Super Memory," You/Kurumi call it "Mental Guts", Tsugumi/Makoto call it "Concentration", and Takeshi/Makoto settle for "Concenmemory".
"A girl who doesn't have an older brother can call someone who's like a brother to her, 'Onii-chan'" — a "made-up" rule stated by Coco near the end of the game, but one that Kurumi also abides to.
A scene with a sleeping male character (who is the only other guy in the group apart from the current protagonist), who mutters things in his sleep that change/randomize depending on how many routes have been cleared beforehand.
The entire epilogue, where everyone is going home on a boat. Not necessarily Book Ends in Never7, but the idea seemed to be pulled from there.
Stepford Smiler: You, Coco, and Sara, though the last is a slight subversion as her Genki Girl personality is actually genuine due to being free from Leiblich.
Coco is really only like this in a few scenes in her route, and Hokuto can see through it. Most of the time, she's genki to the extreme, and when she does get sad or depressed, she shows it.
Sugar and Ice Personality: Tsugumi. When she's not being visibly disgusted with everyone (especially Takeshi), she'll prefer a cold emotional distance.
Talking to Himself: Takeshi and the Kid, which happens in the prologue and the end of the game, but is otherwise averted due to them having no voiced lines in their own routes. The two Yous also go through this.
At the end of their routes, the game does slip up and show that their hair color is not as the player expects them to be, but most of the time, the attention is drawn to something else. See the Tear Jerker that is Tsugumi-Sora's bad end.
Averted on the one of the covers for the game, which blatantly shows Takeshi with bluish black hair.
The Dog Was the Mastermind: The one who came up with the plan is Blick Winkel (a sort of player avatar) with the goal of tricking himself and ultimately allowing Hokuto to call out 17 years into the past to his father. Basically, the player the mastermind behind the plans to trick himself.
Its hard to say who is the real mastermind though. Blick Winkel told You'haru the plan only because he knew about the plans from watching You'haru and Kaburaki carry it out in the year 2034. However, You'haru and Kaburaki only carried out the plans because they were told to do so by Blick Winkel. But Blink Winkel told them the plan only because he knew about the plan from watching... See the Temporal Paradox here? No one will ever know who originally came up with the plan. Then again, if you studied real life Time Travel philosophers, you might argue that the plan did not originate from anywhere, and it never needed to.
The Rashomon: Takeshi and the Kid both come off as being far more competent and interesting in their own routes. In Takeshi's routes, the Kid is a semi-stable, emotional kid who follows whatever the group says. In the Kid's routes, Takeshi is a huge Butt Monkey. But it's a huge subversion because both of these are correct. 2017 Takeshi is much more confident and has stronger leadership qualities than 2034 Takeshi, who is a grown up version of the Kid from 2017.
True Companions: Takeshi gives a lecture to Tsugumi about the meaning of "nakama" (which is translated as "friend"), though she rejects the idea. By the Epilogue, the 2017 and 2034 groups have essentially become one large group of True Companions.
Tsundere: Tsugumi by the end of her route, and the epilogue.
Updated Re-release: The "Premium Edition", which contained about 15 new C Gs (most of them related to Coco's Route), new sprites, and different bonus pictures. The C Gs and sprites were also included in all PC versions of the game.
Valley Girl: Played for Laughs- In Sora's Route, Sora asks Takeshi to teach her how to act more human-like. The ultimate result is that she begins speaking like the trope. However, after it ends up making Coco cry, Takeshi and Sora agree she should just talk like she normally does.
Verbal Tic: Sara, being a ninja fangirl, sometimes refers to herself as "sessha" and ends sentences with the archaic "de gozaru". The translation renders this as over-the-top flowery Antiquated Linguistics.
Walking Spoiler: The Character Sheet has a separate folder for characters who fall under this trope.
What If the Baby Is Like Me: 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 Sapiens/Cure hybrids who grow up normally, and are immune to the effects of the Cure virus.
What Year Is This?: The Kid asks Takeshi this since he can't remember a thing. Takeshi seems to not know either and has to rely on his admission ticket. Of course, when you're playing as the Kid, "Takeshi" (also known as the "original" Kid) lies to you, which is just the beginning of setting up the enormous Mind Screw that is Ever17.
Translators Cannot Do Math: There are 17 meters between each level, but America doesn't really use the metric system. So they converted it to feet. The only problem is that there are about 3.3 feet in a meter and not just three. So not only do you lose another reference to 17, the conversions aren't done properly in some places.
Yamato Nadeshiko: Sora, Justified as that's her programming as a park employee AI. However, it's subverted at one point in her route after she sees Takeshi and Tsugumi having sex, where she briefly goes Yandere out of confusion.
Achey Scars: In the remake, Hokuto has a knife scar across his arm that Sara gave him during their Tykebomb training that Leiblich forced them through. Whenever he has a dream about his past or tries to remember it, the scar aches.
Big Brother Mentor: Takeshi to the Kid. This was slightly present in the original, but really taken to its fullest in the remake.
Bittersweet Ending: The remake changes Sora's Route from a Downer Ending to this. While Takeshi and Sora still die, instead of futilely copy Sora onto a terabyte disk that won't make it out of Le MU, Takeshi instead uploads a program that makes a copy of Sora and wirelessly sends it to the successor LEMMIH computer, meaning that she'll still live on through that computer.
Chekhov's Gun: A "Lemurian Tablet" is in the remake, a mysterious tablet supposedly from Lemuria that has strange hieroglyphics on it that no one can read, and has Coco's drawing on it. As it turns out, the Lemurian Tablet was created by Blick Winkel (via possession of another person from long ago), and the mysterious hieroglyphics have the details of Third Eye Project written on it.
Chekhov's Gunman: Pipi, who is this version actually contains a quantum computer created by Yoichi Tanaka. When Sora's data is backed up, it backs up into Pipi, and Sora essentially becomes Pipi for the next 11 years until her android body is developed.
Enhanced Remake: Contains an additional route (the Blick Winkel Route, an epilogue of sorts that shows some of the events between 2017 and 2034), rewritten story (the main plot and major events are mostly the same, but a lot of the events in-between are completely different), complete background graphic, additional CGs, character conversion from 2D to 3D, remixed soundtrack, and re-recorded voices.
Fix Fic: Essentially the second half of the Blick Winkel Route, where Blick Winkel uses his powers to fix the Bad Endings and give every route a happy ending.
Laser-Guided Amnesia: Kaburaki's amnesia, which was caused by an incident in 2029 where an experiment on space-time oscillation device designed to create an artificial black hole went wrong. Kaburaki had to manually shut it off, but the effects of the black hole briefly sent his 2029 self's consciousness to his 2017 self. The overload of memories caused 2017's Kaburaki's amnesia, but left him with a few fragments of 2029 Kaburaki's memories, which was the source of his "premonitions".
Memory Gambit: In this version, Hokuto was also one of the members of the Third Eye Project, due to his compatibility with Blick Winkel, and therefore had known he was going to lose his memory ahead of time.
Psychic Powers: In addition to Coco's from the original, it's revealed at the end of her route that Kaburaki is a low-level psychic. Furthermore, Professor Yagami in this version was actually researching these powers and their connection to the Third Eye.
Schrödinger's Cast: In the original, Professor Yagami's fate was never revealed, leaving it unknown what happened to him after Tief Blau broke out. Here, he managed to escape from LeMU, made a miraculous recovery from TB, and became a major supporter of the Third Eye Project.
Stable Time Loop: A variation from the original- in the remake, Blick Winkel can only talk to other people when he's in possession of Takeshi or Hokuto (or if they have the Third Perspective, like the former two and Coco), and can't talk to anyone else. As a result, he can't directly tell You"haru" the Third Eye Project. As a result, he goes back in time and creates the "Lemurian Tablet", writing down all the details of the Third Eye Project.
Stepford Smiler: Sara, who was a subversion in the original, has it played straight in this version, though she still has moments of genuine happiness.
Tykebomb: In this version, Hokuto and Sara were trained to be agents of Leiblich, teaching them how to use weapons and various other things. However, Hokuto was removed from training when he was 11 after he protected Sara from a bomb she accidentally set off, injuring him badly. This allowed You"haru" to use her influence to get him out of there.
Vocal Evolution: In the original game, Soichiro Hoshi had two distinct voices: his "Takeshi" voice (which he uses for Takeshi and adult Kaburaki) and his "Kid" voice (which he uses for kid Kaburaki and Hokuto). By the Xbox 360 remake, he's developed a distinct voice for all four (his adult Kaburaki and Hokuto voices are similar to their original types, but slightly different).
