->''"Beyond the Hole is a Moment from the past. The Holes you open must be closed, or time won't start up again. The holder of the Pen must have the Time to use it. Once you've gotten the hang of the Pen, come and rescue us..."''

''Time Hollow'' is a point and-click AdventureGame for the Nintendo DS. The player takes the role of Ethan Kairos, an OrdinaryHighSchoolStudent living with his parents, starting on the evening before his seventeenth [[TheHerosBirthday birthday]]. However, during the night, Ethan dreams that his parents are caught in a fire, and upon waking discovers that he lives with his uncle and his parents disappeared twelve years ago. He then inherits a Hollow Pen: an [[InvisibleToNormals invisible]] pen that can create holes through time. With this, Ethan tries to find out what happened to his parents and stop it from occuring. However, a figure from the past is always one step ahead...

!!The game provides examples of:

* AerithAndBob: Ethan, Timothy, Pamela, Derek, Irving, Mary, Jack, Vin, Ashley, Ben, Morris, Eva, Aaron, Olivia, Emily, Sara, Jacob...Kori, which is just an [[MyNaymeIs unusual spelling]] of Cory.
* AnimeHair: Ethan's hair has sideways spikes, and plenty of characters have strange hair colours.
* AnyoneCanDie: There are probably ''less'' named characters who don't die in one alternate timeline or other than ones that do.
* BaitAndSwitchCredits: Being able to see the treehouse catching fire (you only see the planted stick) and Ethan running through a Hole.
* BerserkButton: [[spoiler: ''Ben Fourier'' of all people, whom Ethan describes in his profile as "kind of a wuss, but not a bad guy", has one. The berserk button is dogs. When Ben was a child, he was taking care of a dog named Shiloh, but one day there was a huge lightning storm that set the treehouse on fire... and Ben ''forgot to untie Shiloh from the treehouse before he left,'' causing Shiloh to burn to death. Ben is tormented with guilt, so when he sees a dog named Lucky, he flips out and starts hitting the dog. The little boy who owns the dog calls for help, Aaron comes out of the cafe to investigate the commotion, and his attempt to save the boy from Ben causes the two of them to fight, which depending on whether Ben has access to pliers or Aaron has access to a rock will end up with either Ben or Aaron hospitalized/dead.]]
** [[spoiler: And Emily Niner has a more minor example: as Ashley finds out the hard way in one alternate reality, if Ashley loses money that would've bought Ethan a present, this makes Emily mad enough to shout at Ashley, and if the flashback's picture is accurate even apparently shove Ashley to the ground.]]
* BettyAndVeronica: Shy Emily and boisterous Ashley. True to form, there's a ThirdOptionLoveInterest thrown into the mix, although she's got certain complications.
* CastFromLifespan: Using the pen accelerates your aging process. We see several users who've gone quite gray after using it too much.
* CatsAreMean: Ethan gets a nasty scratch at the beginning of the game when he tries to [[HatesBaths bath Sox]].
* ChekhovsGun: [[spoiler:The scars on Irving's hand are from the incident at Kako High School's rooftop where he pushed Kori off it and she tried to hold onto him, unsuccessfully.]]
* CloseEnoughTimeline: Ethan doesn't bother to fix the timeline in which Morris has dropped out of school because he seems happier that way.
* ColourCodedTimestop: Everytime time stops, the world turns grey.
* DangerousSixteenthBirthday: Ethan turns 17 when he's given the Hollow Pen. He'll need it to repair the horrible deaths of his friends and family throughout the game.
%%* TheDogWasTheMastermind: [[spoiler:Sox. Maybe.]]
* DoppelgangerReplacementLoveInterest: Of a sort. [[spoiler: After Kori is saved by uncle Derek, the ending cut scene reveals a [[IdenticalGrandson girl who looks extremely similar,]] and is implied to be his cousin.]]
* EconomyCast: There's a total of 13 last names of characters in the game, with either siblings or parents doubling up. The same few faces will keep showing up, with almost no disposable characters.
* EducationMama: Morris, though he loves to learn ([[spoiler:even studying in his spare time after he drops out of school]]) and gets top marks, is made miserable by his grade-minded parents.
* FourIsDeath: [[spoiler:Ben '''Four'''ier kills Aaron with a pair of pliers in one reality.]]
* GainaxEnding: [[spoiler:So... the pink-haired girl at the end of the game is Ethan's cousin, or a time duplicate, or what?]]
* TheGlassesGottaGo: You can make Ethan enforce this trope on Emily by [[VideoGameCrueltyPotential having him steal her glasses from through a Hole]]. You're given several opportunities to give them back, but [[VideoGameCrueltyPunishment if you don't...]]
* GuideDangIt: A minor example in chapter 1. Depending on whether you place an envelope of money in a locker or outside the Chronos Cafe, [[spoiler: Ethan receives either a bag of homemade cookies, or a homemade birthday card. Obviously the bag of cookies is the better gift, but there's no hint as to which solution results in which. You're actually supposed to place the envelope inside the locker so you can get the cookies; if you place it outside Chronos, Emily and Ashley don't have time to get you any real presents, so they settle for a birthday card.]]
* IdenticalGrandson: At the end of the game, [[spoiler:a girl with pink hair greets Ethan at Kako High School. She looks ''exactly'' as Kori. It's implied she's Kori and Derek's daughter.]]
* IdiotHero: There are idiot heroes. And then there is Ethan Kairos. When his friend Morris tells him of a book about parallel universes that might greatly inform his current predicament, Ethan thinks about it for a moment - then decides he can't be bothered to retrieve it from their clubhouse and wants to go to a nearby antique shop instead. He routinely, [[StupidityIsTheOnlyOption stubbornly refuses]] to acknowledge the blindingly obvious and just as often fails to do ''anything'' to follow the leads that are actively handed to him.
* ImprovisedWeapon: A pair of needle-nose pliers may not sound like a particularly impressive weapon, but that doesn't stop [[spoiler: Ben from ''killing'' Aaron with them]] in one timeline.
* InSpiteOfANail: Despite [[spoiler:Mary's]] best efforts, nothing seems to stop [[spoiler:her son from killing Kori]]. The fact that this seems to be an invariant in the timeline drives the main plot of the game.
* InTheBack: [[spoiler: Kori is stabbed with a knife in the back by Irving (or rather, Jack) at the end of the penultimate chapter. This makes her vanish of existence, as she had been displaced of time prior to the game's beginning.]]
* InvisibleToNormals: The hollow pens themselves can only be seen by other hollow pen users. Even former users can no longer see them.
* IWantMyBelovedToBeHappy: Uncle Derek exhibits this with [[spoiler:his younger self]] in the game's final timeline, as [[spoiler:after going back in time and saving Kori's life, he's show to have gone into hiding and watched his younger self grow up and marry the girl he loves.]]
%%* {{Joshikousei}}: Kori, Emily and Ashley.
* KillAndReplace: [[spoiler:Irving]] goes back in time several years ([[spoiler:thus escaping the flow of time]]), kills [[spoiler:Ethan's teacher]] and assumes his identity from then on. Ethan is the only one who remembers this thanks to his RippleEffectProofMemory -- the rest of the world doesn't know this impersonation ever happened.
* KindheartedCatLover: Good thing, too, since your cat helps you out in your adventure.
* KnifeNut: [[spoiler:Irving]] seems to have knives as his weapon of choice. [[spoiler:Mary even mentions that stopping him from pushing Kori just leads to him stabbing her.]]
* LikesOlderWomen: Ben shows traits of this, as does Aaron in a world where he never meets Olivia.
* MakeWrongWhatOnceWentRight: The BigBad does a lot of this.
* MayflyDecemberRomance: [[spoiler:Kori/Derek and Kori/Ethan, although the former is finally able to happen normally once the final version of her is saved without having to leave the flow of time.]]
* MeaningfulName: "Kairos", according to ThatOtherWiki, refers to the exact moment an action must be taken for it to work.
* {{Meganekko}}: The cute Emily wears a pair of glasses.
* MegaNeko: Okay, how many people thought that the stuffed Sox was an ''actual'' cat?
%%* MindScrew: With so much time travel, how could it not be?
* MyGodWhatHaveIDone: [[spoiler: Emily, in one timeline, caused Ashley to run off and disappear by yelling at her and shoving her when Ashley supposedly lost the money needed to buy Ethan a present.]]
%%* MysteriousWaif: Kori
* NeckSnap: This is how [[spoiler: Morris]] gets killed in one of the timelines you must fix.
* NeverMyFault: [[spoiler:Irving, ''big time''. At one point in the story, he says the Kairos family exists to torture him. There are two problems with his theory; one, ''he's'' the one doing the torturing every time he screws up the timeline and does something nasty to Ethan's parents or friends. Two, he thinks the Kairos family is torturing him by killing his mother, Mary. But Mary is actually killing ''herself''...and she's doing this because ''Irving keeps deciding to kill Kori''!]]
* NewGamePlus:
** After completing the game, you can start over and stop the ''entire game'' from happening at the prologue. With your memories from the endgame, you have to convince the BigBad to abstain from MakeWrongWhatOnceWentRight so you can directly avert his DarkAndTroubledPast [[SequenceBreaking ahead of time]]. Needless to say, this rerun is ''very'' short: it takes less than 30 minutes to complete.
** There is a second one, which is nearly identical to the first except near the end. Some dialogues change and give more meaning to Sox's role in the game.
%%* NewTransferStudent: Kori
* NoOneCouldSurviveThat: [[spoiler:Jack falls off a cliff in the road where the bus crash happened. He's considered dead, but he suddenly makes an entrance at the end of the game to try and foil Ethan's attempt to avert Kori's death ''and'' displacement of time.]]
* NoRomanticResolution: Ethan never does pick between Emily, Ashley and [[spoiler:Kori - or, when she's pulled out of the running, her [[IdenticalGrandson identical]] [[KissingCousins daughter]]]].
* NotTheFallThatKillsYou: [[spoiler:How Derek saves Kori. He appears in midair, stops her fall, and the remainder of the fall isn't enough to kill her with him cushioning her.]]
* NotQuiteDead: [[spoiler:It turns out that Jack didn't die after falling from the cliff in the penultimate chapter. You learn this the hard way: he tries to foil your attempt to avert the cause of every conflict in the endgame.]]
* NotQuiteTheRightThing:
** Ethan prevents an accident where a woman he knows dies, but the accident instead injures a boy and kills his dog. The only way to save all of them is to not to fix the woman's bicycle, which is what Ethan did first to save the woman, but to fix the truck that caused the accident in the first place.
** He also prevents [[spoiler: Ben Fourier from killing Aaron by taking away his pliers, but that causes ''Aaron'' to win the fight instead and put Ben in the hospital. Or, if the player removed the pliers in advance, Aaron wins the fight first by shoving Ben down as Ben hits his head on a rock, so Ethan fixes it by moving the rock...but then Ben beats Aaron instead. The only real way to stop the fight is to go further back in time and save the life of a dog Ben left tied up in a fire, to prevent Ben from getting traumatic memories every time he sees a dog, which is what always starts a conflict between him and Aaron]].
** He also saves someone else's life, but causes his friend to drop out of high school. Unlike with the previous examples, [[CloseEnoughTimeline Ethan doesn't bother to fix this]].
* NumericalThemeNaming: Irving Onegin, Jack Twombly, Vin and Ashley Threet, Ben Fourier, Morris Fivet... This continues to Kori Twelves.
* OffingTheOffspring: [[spoiler:Mary Onegin keeps changing the past to cause her and her son's deaths when she realizes he's pure evil. Unfortunately for her, he always ends up living and she always dies.]]
* OlderThanTheyLook: [[spoiler:Kori is no longer a teenager even if she looks like one. She hasn't aged a bit in some years since she was displaced from time.]]
* OmniscientCouncilOfVagueness: [[spoiler:And do we ever learn who they are or what they want? No! They only speak in shadows ''once''. It could just be Kori and Irving, but there's no proof of that]].
* OrdinaryHighSchoolStudent: Ethan had a normal life until his 17th birthday, which saddles him with the conflict of the Kairos-Onegin families.
* PhotographicMemory: Flashbacks seem to work like this. They are literally represented as still images, though Ethan has to ask other people for such things as the date and location. In one instance, Ethan learns of the time of a flashback from a clock shown in the flashback itself.
* PowerPerversionPotential: Ethan can have lots of fun coping a feel of Emily and Ashley in some flashbacks.
* RedHerring: At the beginning of the game, Derek comes over to borrow money from his brother Timothy, who refuses and scolds Derek for "relying" on the Kairos family. Derek loses his temper and accuses Timothy of always having been "down" on him, and then leaves while advising Timothy to watch his back. This makes Derek look incredibly suspicious, almost like he's going to be the villain of this story, complete with a motive...[[spoiler: nope, actually he's one of the ''heroes'' of this story, the villain turns out to be someone else entirely.]]
* RippleEffectProofMemory: Anyone who is a holder of a Hollow Pen or does not experience time has this. Occasionally overlaps with OnlySaneMan, such as when [[spoiler:Irving kills Ethan's homeroom teacher in the past and assumes his identity.]]
* SaveTheVillain: Ethan tries to save the BigBad from falling off a cliff. He's unsuccessful. [[spoiler:The fall doesn't kill him, though, and he's going for Ethan in the next chapter.]]
* SayingTooMuch: This is what first tips Ethan off that something's off about [[spoiler: Irving. When Ethan visits Irving's shop, Irving talks about two high school girls, namely Emily and Ashley, buying Ethan a clock for Ethan's birthday. But the reality in which that happened was wiped out of existence earlier in the game, so in this reality they only made cookies or a birthday card! So how the heck would Irving know about the reality in which they bought a clock...unless Irving also has a Hollow Pen?]]
* ScarsAreForever:
** The game's theme song contains the lyric "No scar ever heals."
** [[spoiler:Irving]] has visible scars from an incident nineteen years earlier.
%%* SecondEpisodeMorning: In chapter one.
* SecretKeeper: [[spoiler:Morris]] in two early realities, and [[spoiler:Uncle Derek]] in those near the end.
%%* SetRightWhatOnceWentWrong
* {{Sidequest}}: [[spoiler:Preventing Vin's accident so he can continue playing basketball is completely optional and unadvertised.]]
* SpiritualSuccessor: To ''VideoGame/ShadowOfDestiny''.
* SpoilerOpening: Kori falling from the school. Actually, [[TrailersAlwaysSpoil the entire opening spoils most major events of the game]].
%%* StableTimeLoop: [[spoiler:The ending.]]
* StalkerWithACrush: [[spoiler:Irving in the past]]; this later upgrades to "just plain crazy" with his crossing of the MoralEventHorizon.
* TakingTheBullet: It's a knife, but [[spoiler: Kori jumps in front of Ethan, when Irving tries to kill the other Hollow Pen user.]]
%%* TemporalParadox: Mostly averted.
* TenderTears: [[spoiler: In one timeline, Emily explains that it was her fault Ashley disappeared, since Ashley ran off after Emily didn't believe her about the lost money. Then we get a picture of Emily crying, eaten up with guilt.]]
* ThemeNaming: All characters apart from members of the Kairos family have a surname based on one of the twelve numbers on the clock. ''Kairos'' itself is Greek for "the perfect moment".
* ThemeTuneCameo: Ethan's ringtone is the game's theme song.
* TimeStandsStill: Whenever someone uses a Hollow Pen, this happens to any non-user. [[spoiler:Or those pulled out of time.]]
* TimeTravel
* TimeyWimeyBall: For most of the game the laws of time travel are consistent. However, for the sake of drama, there are a couple of key points near the end which break the story's own rules.
%%* TomboyAndGirlyGirl: Ashley and Emily.
* VehicularSabotage: In one timeline, Irving cuts the brakes on Olivia's bike, and she subsequently dies in an accident
* WhatHappenedToTheMouse: The OmniscientCouncilOfVagueness segment.
** A potential problem for any player on a given play-through, given that it's entirely possible to miss out on changes you can make in some pasts (e.g. fixing Morris' or Vin's lives), despite being made aware that they could use some Hollow Pen help.
* WhiteGloves: Irving wears some of these [[spoiler:to hide the scars he received from Kori]].
* WhiteHairBlackHeart: [[spoiler:Irving]] has white hair and fulfills the role of main villain.
* WhyDontYouJustShootHim: Zig-zagged. [[spoiler:Irving]] switches between trying to stop Ethan by messing with the past and just plain trying to shank him with alarming frequency.
%%* YouCantThwartStageOne: Averted in the extremely short NewGamePlus.
* YoungerThanTheyLook: Timothy Kairos, Irving and [[spoiler:Mary Onegin, all due to using Hollow Pens.]]
