"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 Adventure Game for the Nintendo DS. The player takes the role of Ethan Kairos, an Ordinary High School Student living with his parents, starting on the evening before his seventeenth 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 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:
Aerith and Bob: Ethan, Timothy, Pamela, Derek, Irving, Mary, Jack, Vin, Ashley, Ben, Morris, Eva, Aaron, Olivia, Emily, Sara, Jacob...Kori, which is just an unusual spelling of Cory.
Anime Hair: Ethan's hair has sideways spikes, and plenty of characters have strange hair colours.
Anyone Can Die: There are probably less named characters who don't die in one alternate timeline or other than ones that do.
Bait-and-Switch Credits: Being able to see the treehouse catching fire (you only see the planted stick), Ethan running through a Hole, and Ethan being the one to jump out the window and grab Kori.
Education Mama: Morris, though he loves to learn (even studying in his spare time after he drops out of school) and gets top marks, is made miserable by his grade-minded parents.
Four is Death: Ben Fourier, who kills Aaron with a pair of pliers in one reality.
Gainax Ending: So is it Ethan's cousin, or a time duplicate, or what?
Identical Grandson: The most common interpretation of a certain point in the ending.
Idiot Hero: 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, 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.
Improvised Weapon: A pair of needle-nose pliers may not sound like a particularly impressive weapon, but that doesn't stop Ben from killing Aaron with them in one timeline.
In Spite of a Nail: Despite Mary's best efforts, nothing seems to stop her son from killing Kori. The fact that this seems to be an invariant in the timeline drives the main plot of the game.
Invisible to Normals: The hollow pens themselves can only be seen by other hollow pen users. Even former users can no longer see them.
I Want My Beloved to Be Happy: Uncle Derek exhibits this with his younger self in the game's final timeline, as 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.
Mayfly December Romance: 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.
Meaningful Name: "Kairos", according to That Other Wiki, refers to the exact moment an action must be taken for it to work.
Not the Fall That Kills You: 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.
Not Quite The Right Thing: Ethan prevents an accident where a woman he knows dies, but the accident instead injures a boy and kills his dog.
He also saves someone else's life, but causes his friend to drop out of high school. Unlike with the previous example, Ethan doesn't bother to fix this.
Numerical Theme Naming: Irving Onegin, Jack Twombly, Vin and Ashley Threeth, Ben Fourier, Morris Fivet, I can keep going...
Offing the Offspring: Mary Onegin keeps changing the past to cause her and her son's deaths when she realizes he's a Complete Monster. Unfortunately for her, he always ends up living and she always dies.
Photographic Memory: 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.
Power Perversion Potential: Ethan can have lots of fun coping a feel of Emily and Ashley in some flashbacks.
Ripple-Effect-Proof Memory: Anyone who is a holder of a Hollow Pen or does not experience time has this. Occasionally overlaps with Only Sane Man, such as when Irving kills Ethan's homeroom teacher in the past and assumes his identity.
Theme Naming: 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".
White Gloves: Irving wears some of these to hide the scars he received from Kori.
White-Haired Pretty Boy: Irving, although not pretty, does have white hair and fulfills the role of main villain.
Why Don't You Just Shoot Him?: Zig-zagged. Irving switches between trying to stop Ethan by messing with the past and just plain trying to shank him with alarming frequency.
