Who... are you?

Who... am I?

Ever17, the second game in the Infinity series, is a Visual Novel made by the now-defunct studio KID, and was one of the first non-erotic 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.

Two Drama CDs were made which act as supplemental stories for what occurs after the game's ending. Fan translations of them have been made.

A sort of Fan Translation patch named Ever17 Himmel Edition was released in 2018 in Reddit. It optimizes gameplay for modern PCs, improves the interface and fixes several translation issues from the original Hirameki-translated script. You can download it for free here.

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, you probably shouldn't look at this page at all before playing the game.


Provides examples of:

  • Action Mom: Tsugumi, if "After You've Gone" is to be believed, is pretty decent in a fight.
  • The Ageless: People infected with the Cure virus age five years before all their cells are replaced with Cure cells, at which point they stop aging. Tsugumi is the primary Cure carrier, but eventually Takeshi, You'Haru, Kaburaki and Coco are all infected as well.
  • 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 Never 7, the first game of the series.
  • Ambiguously Human: It's hinted once or twice that Hokuto and Blick Winkel might really be the same being in some way and that the latter was once less passive of an existence than it is in the “present.” Further, Coco says that she's the same kind of being as Blick Winkel.
  • Ambiguous Situation: Unlike most of the mysteries, it's never made clear what exactly happened in the game of kick the can.
  • Ambiguous Syntax: Near the end, Takeshi says there are five people before correcting himself to say there are six. He means the five members of the group that came down plus Sora, but the rescue squad counted the dead researcher. Meaning that Takeshi and Tsugumi believe Coco was picked up because they count the people as Sora (“dead”) themselves and then You, Coco and the Kid. The rescue operators, however, count it as one dead person from LeMU, Tsugumi and Takeshi left behind and You, the Kid and the researcher picked up. Coco was left behind because she got out of her tube.
  • Arc Number: 17 or various multiples of it appear constantly. The conversions from metric to standard were often done incorrectly, presumably to keep the reference to 17.
    • A few of the times/dates have 17 in them.
      • The most obvious one, being that the year is 2017 except when it's really 2034.
      • Coco's birthday falls on December 17th, 2002.
      • Blick Winkel comes into existence on May 1st, 2034 at 3:17 PM.
      • At 11:17 AM, the final scene of the story begins.
    • Distance are usually measured with multiples of 17 as well
      • 17 meters (56 feet) between each floor of LeMU.
      • The distance Takeshi has to swim to get to Tsugumi's hamster in a sealed off room is 51 meters.
      • IBF is located 119 meters beneath the surface.
      • At 68 meters Takeshi decides to enter the airlock and leave the submarine so that it'll float to the surface and save Tsugumi.
      • Every depth checkpoint Pipi goes by when swimming back to IBF is a multiple of 17.
    • Whenever possible, things seem to happen in increments of 17.
      • 17 minutes from the first round of investigation finishes until the next meetup is scheduled.
      • 17 minutes in the decompression chamber in the prologue.
      • 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.
      • You's father disappeared 17 years ago, when she was 1 year old.
      • The park will collapse in 119 hours.
      • 170 seconds after overriding Sora's authority security overrides LeMMIH regains power.
    • Shows up in various miscellaneous places.
      • Takeshi mentions the Ninneko Song 17 when Coco starts calling him Takepyon.
      • 34 rings in Tsugumi's Jewel Chocolate metaphor to Kid.
      • 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.
      • 34 matches against Pipi in a silly face competition and 34 losses.
      • A type 34 error occurs when trying to hack into Leiblich. Other errors occurred before that, but this is the one that causes Sora's contradicting programs to split in two.
      • In the story of the 800 year old nun, the beautiful young girl is 17. Her boyfriend dies at age 34.
      • In Kid's perspective, when the characters are arguing about names to call him by, one of the suggestions sounds like "Astatiné Kumegawa". Astatine is the chemical element with atomic number 85.
      • Sora's official designation is "LM-RSDS-4913A". 17^3 = 4913, and 4 + 9 + 1 + 3 = 17.
      • The code that Sara is said to have cracked had a 68-bit key, and the one protecting LeMMIH is 136 bits.
    • Uchikoshi finally revealed in an interview why he chose 17 as the arc number: his birthday is on the 17th. This took Nakazawa by surprise now knowing that there really wasn't that deep of a reason to choose 17.
  • Artistic License – Biology:
    • Tsugumi states that after five 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.
    • Jumping from 12.5 atmospheres to 1 atmosphere is suicide, yet Takeshi manages to do this with no ill effects. Then again, he was told this would kill him and it probably would have if he didn't have Cure.
  • Audience Surrogate: Blick Winkel is just an observer with no real attachment to what's going on. He simply watches events unfold as though they were completely unrelated to him. In other words, he's exactly like the reader of a story.
  • Back from the Dead: The narration claims that Takeshi is dead when Blick Winkel / Hokuto revives them. In fact, he should have been dead for quite some time. It's speculated briefly onto how this could be possible, but it's brushed aside.
  • Belligerent Sexual Tension: Takeshi spends most of his time fighting with Tsugumi as she tries to resist getting close to him and sticking to her 'woe is me' values. It gets so bad at points that they nearly comes to blows. However, in Coco's route, Coco's presence in one or two scenes keeps them from getting acrimonious and smooths out the later problems in Tsugumi's route, cutting out much of this part of their dynamic.
  • Beneficial Disease: 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.
  • Bilingual Bonus:
  • Bittersweet Ending: In Tsugumi's ending, everyone escapes the park and the lab below. However, on the way out, 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, Coco was unknowingly left behind.
  • "Blind Idiot" Translation: Not as bad as some, but it has its moments.
    • A line that's supposed to be like "Of course I know what a hacker is" became "Naturally, I knows the hacker".
    • "Kid" was originally going to be referred to as "Youth", but at some point they changed it — with a really sloppy find-and-replace job. For some reason, it ignored spaces, leaving us with baffling typos like "Kidere" and "Kidink," instead of "You there" and "You think".
    • "Tooling test" was suppose to be "Turing test".
  • Blood from the Mouth: Tief Blau causes internal bleeding, puking blood and makes the sinuses bleed, which is invariably fatal if untreated. Even both of the possible treatments only delay it so that the body can try to fight it off, giving it a low success rate.
  • Book Ends: Both the prologue and the epilogue start on a boat, narrated by Takeshi.
  • Broken Bird: Tsugumi is clearly holding some sort of dark past that makes her very unsocial. To make a long story short, she was infected with a disease that made her immortal and hard to kill, which caused her to be experimented on for eight years. By the second incident, she's even worse.
  • Calling the Old Man Out: In You's ending, she gives her mom an earful for lying to her about her parentage and essentially manufacturing her Backstory wholesale.
  • Casual Danger Dialogue: Even as he prepares to exit a submarine on the ocean floor and inevitably drown, Takeshi sits and laughs about how Tsugumi must surely know what he's doing. After all, she's the one that taught him about buoyancy.
  • Chekhov's Gun: The Archimedes principle comes back up when Takeshi jettisons himself from the submarine so it'll have enough buoyancy to take Tsugumi to the surface. Down in IBF it's mentioned that the oxygen pods have numerous other functions like cryogenic stasis. The life readings being 6 and still saying 1 at the end when everyone is gone is a hint not brought up until the Coco route where Hokuto points out that the reading should be 5 since Sora has no real body. The flawed readings is probably due to Blick Winkel, though in what way is hard to say. There's many more than that, many of which aren't even explained directly.
  • Chick Magnet: Takeshi. Both Tsugumi and Sora fall for him short order, the latter of which shouldn't be possible. Yubiseiharukana also confesses to him in the Takeshi bad ending. His daughter Sara also says that he's definitely her type.
  • Chekhov M.I.A.: You's father disappeared seventeen years ago, but she's still looking for him. 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.
  • Classified Information: Security restrictions prevent Sora from volunteering everything she knows, which first comes up in regards to how her AI works and where her personality programs are stored and later when Tsugumi successfully uncovers the lab beneath LeMU, which Sora knows about but can't talk about.
  • Clone Angst: Inverted. The You in the Kid's routes (Yubiseiakikana) is a clone of the You in Takeshi's routes (Yubiseiharukana); however, it is 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.
  • Closed Circle: Six or so people all trapped at the bottom of the ocean inside a theme park that only has roughly six days before it collapses due to the water pressure. The exits are sealed, communications are cut and there is no cell phone signal.
  • Continuity Nod: Several to Never7, such as the mentioned characters of Shigezo Morino, the father of Izumi and Kurumi Morino, and Julia, one of the origins of Cure Syndrome.
  • Corporate Conspiracy: The accident in the LeMU park is caused by Leiblich Pharmeceuticals attempting to cover up the fact that a very deadly virus they manufactured, Tief Blau, had been released within the park. In the epilogue You has given the go ahead sign for a long planned whistle blower operation, resulting in massive public scrutiny on Leiblich, which is forced to close down.
  • Cover-Blowing Superpower:
    • 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, she doesn't catch Tief Blau, meaning You's suspicions that she's a Cure carrier are confirmed.
  • Covered in Scars: Beneath her form concealing clothing, Tsugumi's skin is crawling with scars. Most are long healed in appearance, but still there.
  • CPR: Clean, Pretty, Reliable: Subverted. When it seems like Sara has drowned token efforts are made to revive her with CPR, but everyone gives up instantly. The Kid keeps at it when everyone tells him it's useless, but it works out and she vomits a great deal of water.
  • Curtains Match the Window: Coco, the only one with an impossible hair color. Her pink eyes match the pink hair.
  • Daddy Had a Good Reason for Abandoning You: Even if Tsugumi could evade Leiblich, she knew that the flight would make it so she could never settle in one place for long. Her children could never know peace or go to school. So she put them up for adoption around the time they were two.
  • Dead Person Impersonation: 2017's Kid is playing Takeshi's role in 2034, although real Takeshi is Not Quite Dead.
  • Death Seeker: Tsugumi.
  • Debate and Switch: Tsugumi and Sora's argument about whether or not Sora is hiding potentially life saving information is cut short when Coco begins showing signs of Tief Blau, which overrides Sora's security restrictions enough that she can start volunteering a certain level of classified information.
  • Decoy Protagonist: Not fatal for anyone involved, but the protagonist of both Takeshi and Kid's route is the same person and neither one is Takeshi or the Kid. Rather, it's someone watching the world through their eyes: Blick Winkel. The first LeMu accident in 2017 is replicated in 2034 to make Blick Winkel watch both and confuse them for each other. Set up properly and given enough hints that the two events are separate, he finally wakes up and takes action for himself.
  • 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.
  • Deus ex machina:
    • At the end of the Takeshi routes, Pipi somehow discovers six ampules of the Tief Blau fighting serum.
    • At the end of Coco route Takeshi revives himself from the dead on the ocean floor and swims back to IBF. Hokuto briefly speculates on how this could have happened, but then decides he doesn't care.
  • Diabolus ex Machina: As Tsugumi and Takeshi escape IBF in the submarine, the battery dies and Takeshi has to eject himself onto the ocean floor to give the sub enough buoyancy to reach the surface. After this and sort of between routes this is used as the basis for the Kid's routes: Blick Winkel, You and Kaburaki plan a rescue for Takeshi and Coco, who was also left behind. It requires replicating the first disaster.
  • Disappeared Dad: Part of You's back-story.
  • Does This Remind You of Anything?:
    • You demonstrates a point about perception to the Kid by making him cap a pen with one eye closed. The tip is slippery. It won't go in the hole. It's his first time doing this.
    • People with Cure 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? Word of God has stated that this was a leftover of an old concept that was rejected.
  • The Dog Bites Back: 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.
  • The Dog Was the Mastermind:
    • The one who came up with the plan is Blick Winkel, which is a character the reader didn't even know was the true progatonist of the story. His goal is tricking himself and ultimately allowing Hokuto to call out 17 years into the past to his father.
    • It's 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.
  • Double Standard Rape: Female on Male: In Sora's route, Takeshi is lured into a confined space with Tsugumi, strangled, pinned to the floor, and then subjected to a Forceful Kiss before being stripped and, well. No one seems to consider this rape, least of all Takeshi, whose only objection to having a private conversation with Tsugumi afterwards is that it would be kinda awkward. To exacerbate matters, Sora later tries to murder him for "cheating" on her. Instead of pointing out that Tsugumi didn't give him much choice, Takeshi is simply silent and dejected, implying he agrees with her viewpoint.
  • 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.
  • Dub-Induced Plot Hole: The I Never Told You My Name moment in Kid's part of Coco's route. The translation team forgot to insert the most important part, actually using the name a character isn't supposed to know.
  • Dying Declaration of Love: You to Takeshi in the Tsugumi-Sora Bad End.
  • Earn Your Happy Ending: The final route. Until that point each character went through: crashed underwater amusement park twice in Ryogo and Tsugumi's case, Tief Blau infection, being seperated from family member for years, being hunted by evil MegaCorp, cryostasis, 17 years of plotting to save two friends or all of the above. But ultimately it ended well for everyone.
  • Emergency Transformation: Unintentional, though known to be a risk. A vaccine for Tief Blau is created from Tsugumi's blood, but it also transforms everyone in the first incident into Cure carriers.
  • The End... Or Is It?: At the end of a route, the viewpoint moves back to the control room. There's one life sign left in LeMU. And only you are still trapped in the Infinity loop.
  • Everybody Lives: The True Ending.
  • 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).
    • 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.
  • Find the Cure!:
    • May 6th is devoted to this as everyone is infected with Tief Blau. Ironically, the cure is Cure.
    • This is also pretty much the plot of both Drama CDs, with Sora in "2035" and Sara in "After You've Gone".
  • First Girl Wins: For both protagonists. Although Takeshi (and initially, the player) doesn't realize that it's Tsugumi under the tanuki suit. The next girl would be Coco, who gets paired with Blickwinkel.
  • Flat "What": After eating a sandwich with Takeshi's special ingredients (sage, soy sauce, mayonnaise, Tabasco, etc.), Tsugumi claims it tastes like pizza, and Kid's first thought is this.
  • Foreshadowing:
    • 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.
    • Near the end of each of the routes, there's a CG that fully shows that route's protagonist (although Takeshi is obscured by the text box and Kid's is in the epilogue portion), one of the very few hints that the game's trying to fool you into thinking routes show the same incident.
  • Gas Chamber: The LeMU incident (the first time around, that is) turns out to be an unplanned version of this.
  • Generation Xerox: Deliberately invoked on Yubiseiakikana by her mother, in order to make her as similar to her mother as possible, as part of the Batman Gambit to trick Blickwinkel. As this includes tricking her into thinking she has the same backstory as her mother, You is obviously not happy when she finds out.
  • Get A Hold Of Yourself Man: Takeshi has the option of using one of these on the Kid. Subverted if he does do it, as he instantly regrets it and is looked down upon by the others.
    • However, if you do chose to hit him, Tsugumi's affection points actually go up.
    • And if she does it instead, apparently it's just fine and no one bats an eye.
  • Give Him a Normal Life: Tsugumi put her children up for adoption when she realized that if they stayed with her, they could never settle down and go to school or have friends.
  • 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.
  • 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.
  • Go Out with a Smile: Close, but no cigar. The researcher was trying to smile as he died because of relief that his daughter was okay, but when Takeshi looks at him later he notices that the agony was much and contorted his face.
  • Gratuitous English: The message at the end of every route except Coco's.
    This story is not an end yet. Because only you are in the infinity loop.
  • Gratuitous French: "Comprendez-vous?" As anybody who knows French can tell, the d doesn't belong there, but that can be explained as Takeshi just not being fluent.
  • Gratuitous German: LEMMIH's system declares its announcements in German. Also, Leiblich originated from Germany.
    • There's also Tief Blau (Deep Blue) and Blick Winkel (View/Perspective).
    • All the music tracks have German titles.
  • Greater-Scope Villain: Leiblich Pharmaceutical. Their actions are important to the backstory of several characters but their machinations and fight with them occurs entirely off-screen and they dorm no immediate threat to the characters.
  • "Groundhog Day" Loop: "This story is not an end yet. Because only you are in the infinity loop."
    • Different from most other loops in that, like the game says, it's only Blickwinkel that's experiencing the loop, continually going back and forward in time to 2017 and 2034.
  • Half-Human Hybrid: Hokuto and Sara are classified as such, though not a true example of this trope.
  • Half-Identical Twins: Averted. Sara and Hokuto look very little alike.
  • Hand Behind Head: In the Kid's route, Takeshi's right hand is always behind his head except in one cutscene graphic. This is so ubiquitous that Let's Player little_firebird lampshaded it in their commentary at one point.
  • He Knows Too Much: A lone researcher for Leiblich discoved in 2000 that the company was investigating the disease Tief Blau and planned to develop it into a weapon. To silence him, his family was threatened and he was imprisoned to continue researching until the day he died on May 6th 2017 in front of his daughter, You.
  • Helium Speech: Used in the prologue by Coco. Combined with the fact that her normal voice is already high-pitched... your eardrums will explode.
    • In the remake, Takeshi also has this in the same scene (which makes more sense in hindsight, since all voices, his included, should sound like this without the headphones).
  • The Hero Dies: Takeshi ends up drowning on the seafloor at the end of Tsugumi's route. Coco's route includes this scenario and its continuation, in which he's revived and makes it back to IBF.
  • Heroic Sacrifice: Without a moment's hesitation, Takeshi leaps out the airlock of the submarine so that it will have enough buoyancy to reach the surface and allow Tsugumi to live.
  • 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 Ball: 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 Blick Winkel out on it.
  • 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.
  • Immortality: Shigezo Morino lists three kinds of immortality when talking to You'haru: immortality of body, immortality of memory, and immortality of genetics. In the course of the story it becomes apparent that Tsugumi represents the first, Sora represents the second, and You represents the third.
  • Incest Subtext: In the final route, Coco declares Blick Winkel as both her adoptive brother and her boyfriend. For bonus Squick points, Blick Winkel is supposed to represent the player.
  • Incurable Cough of Death: A symptom of Tief Blau.
  • I Never Told You My Name: When Kid meets Sara on Coco's route the first time she calls her by her real name even though he should only know the nickname You used.
  • 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.
  • Leitmotif: Each of the Love Interests have one based on each of the attractions. Tsugumi's is the Jellyfish Gondola, You's is the Lemurian Ruins, Sara's is the Cosmic Whale, Sora's is the Dolphin Carousel. (Sora also has "Hologramm", which is also the Exposition track.) Coco's is named after the Team Pet rather than an attraction: Weisser Hund, or "White Dog".
  • 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 LeMU uniform remaining exactly the same after it being detroyed, rebuilt, and 17 years having passed, is also a stretch.
  • Literal Metaphor: Takeshi wants to crawl under a rock and die out of embarrassment when he gets concerned over Tsugumi in public and makes a big stupid fuss when she was obviously okay. So he does the next best thing and rides the elevator back down, wishing he could sink all the way to the ocean floor.
  • Long-Lost Relative: More of a long-lost family in this case.
  • 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 (or 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 Transcends Spacetime: With the twist that it's familial love. Through it, Hokuto manages to project their consciousness into the past to resurrect his father.
  • 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.
  • 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 Jellyfish Gondola (an amusement park ride) in Sora and Coco's routes, and in the IBF sickbay in Tsugumi and Coco's routes.
  • Mama Bear: Tsugumi, as revealed in "After You've Gone". Simply put, do not mess with Hokuto or Sara, or Tsugumi will kick your ass.
  • A Man Is Always Eager: Judging by what little narration we get during the scene where Tsugumi rapes Takeshi, and Takeshi's blase response afterwards, this appears to be the rationalization.
  • Meaningful Echo:
    • In the prologue, You says the line "I am You". Next time, it's said to You'haru by You'aki, to signify that they are the same person.
    • Tsugumi spends the entire story trying to keep her distance from Takeshi and gets angry when he touches her. In the submarine, he tells her not to touch him as he plans to leave the sub through the airlock. Before he exits, she's begging him not to leave her.
  • MegaCorp: Leiblich Pharmaceuticals.
  • Memento MacGuffin: Sara's pendant, which contains a hologram of what she believes is her deceased father.
  • Mental Time Travel: The Kid wonders, in You's route, if his Déjà-Vus and amnesia are caused by this.
  • Minimalist Cast: There are six characters whether you're in the Takeshi or Kid routes plus one researcher and Blick Winkel. All of them are important with only the dying researcher being even somewhat minor. Even then, he's You's father, a Tief Blau researcher and helped design Sora.
  • Mind Screwdriver: Coco's route manages to clear up virtually every mystery in the game.
  • Moon Logic Puzzle: Without a walkthrough, some paths can be difficult to succeed on a first try. Most notably Tsugumi's good end.
  • Morality Chain: Hokuto and Sara were the only things that kept Tsugumi from becoming a Nietzsche Wannabe after Takeshi's death.
  • Morality Pet: Chami is this to Tsugumi.
  • 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.
  • MST3K Mantra: Invoked. How did Takeshi come back from the dead and swim back to IBF? Don't worry about it. Where did Sora get the robot body? Must have been a miracle. How come she remembers something not stored in her memory? Who knows! Just enjoy your happy ending and quit whining about the details.
  • Multiple Endings: An interesting subversion occurs here since the "True End" is actually much, much happier than the so-called "Good Ends".
  • Mum Looks Like a Sister: Youbiseiharukana and her daughter look to be no more than five years apart in age as they very well ought to given the circumstances.
  • No Antagonist: The characters 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.
  • No Name Given: Tsugumi reveals that Hokuto's and Sara's names are their adopted names. It was never revealed what their true names are.
  • Obfuscating Stupidity: Kaburaki in the 2034/Kid routes. It is not only Obfuscating Stupidity, but also Obfuscating Personality.
  • Official Couple: The story is built around the Tsugumi/Takeshi romance and all the repercussion of it. Sora's route simply isn't possible and the Kid/You romance is largely token, going entirely ignored in the True ending until the very last few lines. Coco's official love interest it's Blick Winkel.
  • 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. See also Really 700 Years Old, below.
  • 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, who shares the same first name as Coco's father, Takeshi Yagami (although their names were spelled with different kanji in the Japanese version).
  • Only Known by Their Nickname: The Kid, by virtue of his amnesia, and You, whose full first name is ridiculously long and full of spoilers. It's stated a few times, but deliberately never dwelled on for long. How long it is probably meant that no one bothered to memorize it.
  • Ontological Mystery: You the protagonist are trapped at the bottom of the ocean with six people in total. Figure the rest out for yourself because that's all that can be stated with any real certainty, especially in the Kid's routes.
  • Our Hero Is Dead: Takeshi in both of his routes, of course.
  • Painting the Medium: The prologue has gray text boxes. Then, when you get into one of the protagonists' routes, it becomes green in Takeshi's perspective or blue in Kid's. This distinction pays off in the true ending, when we start switching between them again, as you can immediately see the change. In addition, the prologue is told in third person, while the routes become first person, denoting that Blick Winkel has identified with one of the perspectives, thinking that he is that person.
  • Pair the Spares: Kaburaki and Sora in the Drama CDs, rather awkwardly.
  • 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 different circumstances, they can hardly be blamed. Not that Hokuto and Sara seem to mind...
  • Pinky Swear: One piece of promotional art depicts Coco and Sara, floating in the sea with pinkies clasped. Interesting in that the two of them apparently never interact or even meet in-story until the very end, but have a mysterious connection nonetheless.
  • The Plan: The entire storyline is a massive trick, played by the player perspective, on himself.
  • Player and Protagonist Integration: Uses the "you are you" variant. (And no, that does not mean you are You.) The true protagonist is the perspective behind Takeshi and the Kid: a fourth dimensional being who can freely move through the timestream and influence certain important events (in other words, a video game player).
  • The Power of Love: Hokuto is able to project his consciousness onto Blick Winkel in the past and resurrect his father through this.
  • Pretty Boy: 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 Bishōnen involves major spoilers.
  • Properly Paranoid: Tsugumi. Especially in 2034. At least in 2017 it really was an accident.
  • Psychic Powers: Coco claims to have this, 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.
  • Pygmalion Plot: Takeshi and Sora, sort of.
    • 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 be a Lampshade Hanging, but probably is not.
  • 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 and occasional Jerkass. 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.
  • 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.
  • The Reveal: An early one is that Sora is an artificial intelligence. Her form can't even be called a hologram given that she's actually a projection onto someone's eyes.
  • Rip Van Winkle: The story of Rip Van Winkle is discussed by Takeshi, You, and Coco at one point. This is, obviously, Foreshadowing.
    • The event it foreshadows is Takeshi and Coco sleeping for 17 years in cryo-sleep, although the former counts more than the latter (as Coco had access to Blick Winkel's viewpoint).
  • Robot Dog: You inherited one from a friend. It's quite old, so she's surprised it still works. Not just any robot dog: It's actually Pipi.
  • Robot Girl: Sora, although more of a Holographic AI Girl. In the True End, she does get a robot body.
  • Scale of Scientific Sins: You'hara considers their use of cloning as a means to achieve genetic Immortality to be this, explicitly calling it a "sin". However, they never receive comeuppance for it and seem to come to terms with it in the ending, so this may be their own personal hangup rather than an Author Tract.
  • Self-Mutilation Demonstration: In spirit, at least. Since Takeshi won't believe in 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.
  • Set Right What Once Went Wrong: The entire plot is the attempt of a fourth dimensional being to trick itself into tricking itself so that the 2017 accident can occur without the deaths of Takeshi and Coco.
  • Sex Signals Death: Takeshi dies shortly after having sex with Tsugumi. Sort of.
  • Shown Their Work: The authors clearly knew their way around theoretical physics, as well as just what kind of circumstances would be required to operate an underwater theme park.
  • Shout-Out
    • All of the names that the Kid can choose for himself are the names of protagonists from other KID visual novels, except for Prince (which is a Shout-Out to the KID game Banana Prince):
    • In one of the paths, there'll be a party. You will perform an impression of a strange old archaeologist, who had a talent for cracking a whip.
    • There's a few other Shout Outs to Never7, including:
      • 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 Older Than They Look, and both are quite childish.
      • 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.
  • Significant Anagram: LEMMIH spelled backwards is HIMMEL.
  • Sliding Scale of Idealism Versus Cynicism: The fundamental point of disconnect between Tsugumi. As a defense mechanism, Tsugumi holds the position that life is brutal, unpleasant and undesirable because of the suffering that people go through. Takeshi believes that even though you may be suffering now, life is still beautiful. Further, if you hold out, things may very well improve. This is what Tsugumi likes about him: She doesn't want to think of the world as a terrible place, she wants to have some optimism.
  • Snow Means Love: Not in the traditional sense, but when Tsugumi is narrating the birth of her twins in midwinter the entire background is black with only falling snow to accompany it. Familial love.
  • Soap Opera Disease: You'haru turns out to be suffering from a heart ailment that will take her life shortly, which is why she had herself cloned.
  • Someone to Remember Him By: Tsugumi is impregnated by Takeshi in both of Takeshi's routes as well as the slightly altered version present in the Coco route. When he seemingly dies, she's bitter at the world until she realizes that she's pregnant.
  • Space Whale: The "Cosmic Whale Room" has an animatronic one.
  • Spit Take: Takeshi in Kid's routes, when he hears what You's high school club did.
  • Spoiler Cover: Nakazawa asked an artist to include major spoilers on the box of the ports to try something different. This caused a backlash by past fans who were upset that the artist would give away major spoilers to newcomers much to the surprise of Nakazawa.
  • 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.
  • Supernaturally Young Parent:
    • In the True Ending, Takeshi is 20 except on paper since he's been in stasis for 17 years. His children were conceived only a day or two before he went into stasis, meaning he's not even five years older than they are.
    • 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. 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.
    • By appearance instead of age Tsugumi could plausibly get away with saying she's younger than her children given that she's physically 17 even if her age is about 40. Her kids are 16.
  • Synthetic Plague: While Tief Blau is a modification of an existing organism, it's been molded into a disease with almost universal mortality. Fortunately, it's so quick and deadly that during the break out at the end of Tsugumi and Sora's routes the casualties were limited in scope and area. Further outbreaks are also often limited to only a single person because they don't have time to pass it on. There were still tens of thousands of casualties, however. In the epilogue You'Haru has given the go ahead sign for a long planned whistle blower operation, resulting in massive public scrutiny on Leiblich, which is forced to close down.
  • Team Pet: Pipi the dog and Chami the hamster.
  • Teen Pregnancy: Played with. You'Haru had a child when she was about 16, but it was a clone of herself implanted by a character mentioned in Never7.
  • Temporal Paradox: A very unpleasant one; when Blick Winkel realizes this while seeing the happy future caused by Set Right What Once Went Wrong, Takeshi ''slowly decomposes before his eyes''. It's quite graphic.
  • The All-Concealing "I": Cleverly, neither Takeshi nor the Kid's faces are shown when you play as them, not even in CGs, but they are seen in the other's route. This is to hide the fact that the Kid is not the same Kid we see in Takeshi's route, and vice-versa.
    • 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.
  • Together in Death: Sora's ending.
  • Tomato in the Mirror: When Hokuto/Blick Winkel discovers he's not the Kid from 2017.
  • Tricked Out Time: To resolve the 2017 incident with everyone living through it, it can neither be prevented nor can the fundamental details be changed. To do that would leave no reason for Blick Winkel to travel back. He wouldn't even have been awakened. Instead, Takeshi is awoken on the seafloor, rescues Coco and puts her into a pod and then puts the both of them into suspended animation for seventeen years.
  • 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.
  • Unrequited Love Switcheroo: In a manner of speaking. Takeshi spends most of the story trying to get Tsugumi to open up and after rescuing Chami she finally does, but now he's respecting her personal space when she's finally willing to talk a little, much to her irritation. Before much longer, he's stopped seeking out her company and she comes to talk to him instead.
  • Updated Re-release: The "Premium Edition", which contained about 15 new CGs (most of them related to Coco's Route), new sprites, and different bonus pictures. The CGs 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.
  • Weakened by the Light: 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.
  • Wham Line: You's route offers one, though it's easy to miss what it means.
    'You: My name is... Tanaka... Youbiseiakikana.
  • What Happened to the Mouse?: Two mysteries are never solved: what caused the 2017 disaster and tief blau outbreak, and what was the cause of 2017 Kid's amnesia? The Xbox 360 remake answers the second mystery but not the first.
  • 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 Is This Thing You Call "Love"?: Sora's route revolves around this.
  • 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.
  • Who Wants to Live Forever?: Tsugumi wangsts about being immortal, but Takeshi thinks that life is its own reward, even if he gets momentarily rattled by her grief. This is the fundamental root of the conflict between them: To her, life has been nothing but suffering. To Takeshi, it doesn't matter if you suffer so long as you're alive.
  • Writers Cannot Do Math: In this case, a translation problem. 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.
  • You Already Changed the Past: Found out the hard way.
  • Your Days Are Numbered:
    • It's at least possible for every human to escape from park before it collapses, but Sora is stored inside the computer. She can't escape and while there are copies of her in the primary computer on the mainland, they aren't her.
    • Four years ago from the standpoint of 2017, You was diagnosed with a non genetic heart condition and was told she'd be lucky to make it to graduation. That said 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.
  • Younger Than They Look: Sora, who is 6. Justified in that she's an AI, and her age is given as eternally 24.


The Xbox 360 remake provides examples of:

  • Achey Scars: In the remake, Hokuto has a knife scar across his arm that Sara gave him during their Tyke-Bomb 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 LeMU, 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 graphics, 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.
  • Tyke-Bomb: 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).
