''You are the killer! ... But don't tell anyone. You've killed one of the faculty members and left her body in the main courtyard, heh. Your role in this game is to kill every other player while surviving yourself; therefore, it isn't a great idea to tell everyone that you're the killer. Use your wits and various tools around the school to help in this goal.''

Web-based multiplayer light-role-playing murder-mystery game that runs through the {{BYOND}} [[http://www.byond.com/?page=Start client]]. The game is similar to standard drama fare "Knives In The Dark": one player is the Killer (hereafter referred to in male terms) and must attempt to bury the unfortunates trapped with him before dawn. Alternative game modes include [[Manga/DeathNote Death Note]] mode, in which one character ('Kira') spawns with a Death Note and another has the Shinigami Eyes, forcing the two to work together in order to kill everyone else; and [[VisualNovel/{{Tsukihime}} Nanaya Mode]], an out-and-out free-for-all. The reason for it being Mitadake "High" is because the default map takes place in a high school; an external map editor allows hosts to create additional maps to play on.

MH is heavily influenced by [[VisualNovel/HigurashiNoNakuKoroNi Higurashi No Naku Koro Ni]], Manga/DeathNote, and VisualNovel/{{Tsukihime}}, with many [[ShoutOut shout outs]] to other anime in the bargain.

An updated version known as [[http://www.byond.com/games/MasterBraska/PyrceHigh Pyrce High]] was created by Masterbraska in late 2011. The remake featured several new modes such as Zombie mode, Witch mode, Doppelganger mode and several others. At some point, a character maker was added to the game, allowing users to select their hairstyle and name, but this was poorly received as the color mixer meant all the hair colors were neon-bright and players would play as the same character every round.
In the end, the game broke up due to internal drama with the staff and the userbase jumped ship to Misuterii High, which had just opened for alpha testing

[[http://www.byond.com/games/Metafrosty/MisuteriiHigh Misuterii High]] was created by Metafrosty at the end of 2013 with the intention of making a game that was more true to the original game. It was well received and updated quickly, making many improvements such as having the game run at a higher framerate so it wasn't as choppy as previous games, and adding pixel movement as opposed to grid based movement. Normal mode was given some upgrades with the randomly spawned Suspect and Accomplice roles to breath some freshness into the basic mode.
The game also features a [[Manga/DeathNote Death Note mode]], an [[VisualNovel/UminekoNoNakuKoroNi Umineko mode]], a [[Manga/{{Shiki}} Shiki mode]], a [[Anime/PuellaMagiMadokaMagica Madoka mode]] a [[VisualNovel/{{Tsukihime}} Tsukihime mode]] and an upcoming [[Anime/PsychoPass Psycho-Pass mode]]. Additionally, users can create their own custom modes using "Mystery Script", a language created for such a purpose which also functions with the map maker, allowing for much more intricate custom maps than before.

----
Provides example of:

* ABloodyMess: Bottles of ketchup can be used to make puddles of fake blood.
* AGodAmI: Primarily occurs whenever Kira can form a cult in Death Note mode.
** Also Judgement Mode mostly consist of this.
* AllAccordingToPlan: A good ChessMaster tend to do this.
* AloneWithThePsycho: Tends to happen when LetsSplitUpGang occurs.
* AndThenJohnWasAZombie: Happens often in Zombie Mode when a student hasn't found a cure after having a dangerous confrontation with a zombie. This happens many many times in Misuterii's Shiki Mode.
* AwesomeButImpractical: Alondite. Sure, it can attack from two spaces, but it doesn't even do as much damage as an axe, burns fatigue like nobody's business, and takes up a lot of inventory room. Newbies who rely on it too much have a tendency to get batted down, robbed, and killed.
** Also, there is the server setting that has each in-game hour last an actual RealLife hour. You can probably tell that it doesn't ever get used.
* AxesAtSchool: Knives can be found in students' desks, implying the more common way this trope plays out. Other weapons are found where they should be, at least on the default map - bats in the bat bin rooms, metal pipes in the basement, [[BreadEggsMilkSquick tasers in the teachers' desks]] et cetera.
** Subverted when the mapmaker turns off weapons, leaving the people to wonder how the hell the teacher was murdered, and slowly go mad enough to kill themselves.
* AxCrazy: This happens a lot with bad roleplayers, especially in the [=RK=]-rounds.
* Badass: The majority of the characters.
** BadassAdorable: If someone's playing an obvious {{Kawaiiko}} and using complete sentences, chances are they're both a very good roleplayer ''and'' a very good player. Attack at your own risk.
** BadassNormal: Everyone, except from those with Death Notes, Shinigami Eyes or Mystic Eyes.
** Some players in Pyrce High can take out large groups of players by themselves. With the knife. Given ping below a certain level of course.
* BadPowersGoodPeople: Sometimes the witch is a good guy... [[SubvertedTrope But then again they may be fooling you.]]
* BatmanGambit: Chessmasters love to do this at the end.
* BattleOfWits: Between the killer and the students.
* BatterUp: Baseball bats are available weapons. They come in wooden, metal, and [[ItemCrafting nailed]] variety.
* BewareTheNiceOnes: The killer may be AffablyEvil, and the perfectly normal student who only picked a weapon up to defend him/herself may be {{Badass}}.
* {{BFG}}: The 7th Holy Scripture from Tsukihime sometimes spawns in-game. It is not technically a ''gun'', mind you, but it's awesome nonetheless.
* {{BFS}}: [[FireEmblem Alondite]], a weapon that can be found, can be one of the more effective melee weapons if you fight intelligently since it can hit from two squares away -- though it's weaker than the axe and drains energy insanely quickly, so if you don't kill the opponent within the first few blows, you're in a lot of trouble.
* BigDamnHeroes: When you're at the mercy of the killer another student can always be your saving grace.
* BodySurf: The killer has a lot of fun in Doppleganger Mode.
* BoringButPractical: Forkkie's server rules. [[TakeThat "It's like I can SEE fun, but I can't reach it!"]]
** Most server rules in general are either this, or completely ineffective at preventing idiots from being idiots.
*** Forkkie actually had to ban a lot, but had a ton of good players. Her name was also Forkk. She liked Pancakes.
* BreakableWeapons: ObviousRulePatch to the previously mentioned {{GameBreaker}}s below: the Baseball Bat and Alondite.
* BreakTheCutie: Find a cutie. Attempt to kill said cutie, but fail. Cutie is now broken, if they're a decent [=RPer=].
* CastFromLifespan: In new Manga/DeathNote Mode the shinigami/GodOfDeath can do this with Kira for the sum of kira losing half of his/her game time. For example, if the ingame time is 10 (8 hours left), you'll die when there's 4 hours left.
* {{Catgirl}}s: Strictly speaking, the game contains no sprites like this, but it's easy to RP as one if the server allows you to.
* ChessmasterSidekick: For Kira's side, the game is won or lost by the Shinigami Eyes. A competent Eyes can usually meet up with Kira easily, barring the usual bad luck, stupid random attacks, or a MagnificentBastard among the other students, while an idiot will get themselves killed or keep quiet the whole game. A good Kira ''can'' win without meeting the Eyes, but it's not easy.
* {{Cosplay}}: People like adding this to their character.
* CouldntFindAPen: If you ''really'' need to write something, being covered in blood works just as well as having a Mechanical Pencil in your inventory. Bizarrely, having a weapon that is covered in blood is ''not'' sufficient if you are not bloody yourself, nor can you ever carve your message into the paper with said weapon.
* CriticalExistenceFailure: You're fine as long as you still have a sliver of HP.
* CrazySurvivalist: It's not uncommon to walk into a random room, or especially the basement, and find a barricade, with one of these inside.
* CruelAndUnusualDeath: Death by butterflies!
* CurbStompBattle: Neither love nor money will save you if you are accused of being the Killer and the people playing are idiots.
** Unless, of course, you're just that {{Badass}} and can [[OneManArmy kill everyone yourself.]]
*** Also when you're alone with the witch and the witch does not feel generous.
* DangerouslyGenreSavvy: The Killer must become this in order to win. Some players may need to become this as well to survive.
* DidTheyOrDidntThey?: The only way to find the killer is to question who is the killer.
* DidYouJustPunchOutCthulhu: Technically, any time Ramiel is beaten in combat. Defeating the Witch in battle will cause a similar response both from the other characters and the players.
* DrivenToSuicide: Serious roleplayers will do this if their character and situation requests it. Others will do it if they have to go or are bored with the game.
* DummiedOut: Although Pyrce added Black Haired Girl, Pink Haired Boy is not coded to be given to anybody despite having an icon in both versions. Misuterii does have Pink Haired Boy and Black Haired Girl, though.
* EasterEgg: Nanatsu Yoru and the 7th Holy Scripture from Tsukihime may randomly spawn.
* FaceStealer: This is the only way the doppelganger can change its form.
* FanNickname:
** Green-Haired Boy is commonly known as "Cabbage-kun", and Green girl is "Lettuce".
** The two different hairstyles for Black-Haired Girl is why she has two different nicknames: Hairwings and Hairspider.
** The two characters with goggles, The Boy with Goggles and the Girl with Goggles, are often times named Google, or Go-Go
* {{FanWebComics}}: MitadakeSaga
* GambitPileup: If you're playing a game with several intelligent, witty players with well-thought-out plans, expect this to happen a lot. ''Especially'' in Death Note mode. Obviously averted in Nanaya Mode.
* GameBreakingBug: The taser bug. Tasing someone who's unconscious destroys their inventory; in the case of the holder of the Death Note, this means that there's no more Kira and the game might as well be rebooted.
* GameplayAndStorySegregation: The most common argument amongst players is where the line between good player and bad roleplayer (or the opposite) should be drawn.
* GenreSavvy: You need to be this for your gambit to be on top.
* GlassCannon: The Alondite read above at AwesomeButImpractical.
* GiantSpaceFleaFromNowhere: Ramiel. Of course, he [[RandomEncounters doesn't show up in every game]].
* GoMadFromTheRevelation: You think you know who the killer is? Great, go hunt them down... oh, look, [[SuspectExistenceFailure the REAL killer got to them first.]] That sound is your brain breaking. In-Character, of course.
** On the other hand, a player may have tons of evidence against someone being the killer, and decide to just outright kill them and explain when they have time. By the time you find this out, the person who found it all is already dead.
* GrandTheftMe: The special power of the killer in Doppleganger Mode.
* HeroicComedicSociopath: Startlingly, though unsurprisingly, common.
* HighSchool: Unless you are playing on a custom map which isn't one.
* HitPoints: Measured by a LifeMeter, naturally.
* HuntingTheMostDangerousGame: You are hunting the Killer. The Killer is hunting you.
* IKnowYouKnowIKnow: Experienced players tend to do this with PDA Numbers in Death Note mode: being able to instantly contact your allies is fantastic, but there's the danger that one of them is Kira and could ID you through the school's database (assuming the host hasn't disabled computers due to abuse). If you can grab a PDA off a corpse, you're all set.
* IdiotBall: A great number of games have been lost simply by Kira or the Killer getting a little too overconfident or saying the wrong thing at the wrong time, or occasionally, a paranoid idiot just getting lucky and killing the right person.
* IfYouKillHimYouWillBeJustLikeHim: Sometimes players will try to trap the killer rather than kill him in order to avoid this. A good killer can use this to convince them to kill each other. Occasionally taken literally in Death Note mode - if someone kills Kira, the killer will (usually) pick up the Death Note and assume his role.
* TheLastDance: The killer has everyone against you as well as around you, ready to kill you. What are you going to do?.....''GO OUT LIKE A BADASS!''
* LethalJokeItem: Wooden weapons. Even after the update that made them BreakableWeapons. (It now takes a lot more technique to use wooden weapons than it used to, but they're still wonderful for punishing heavily-armed newbies.)
* ILied: Lots of this due to the nature of the game.
* MadnessMantra: Verbal and written, sometimes both at once.
* MagicalEyes: One player always spawns with the Shinigami Eyes in Death Note mode, and players have a (bizarrely high) chance of spawning with them in Normal Mode, as well as a chance of spawning with the [[VisualNovel/{{Tsukihime}} Mystic Eyes of Death Perception]]. Or both at once. It's happened.
* MagnificentBastard: Some Kiras take extreme joy in [[InvokedTrope invoking this trope]], and a good Kira or Eyes player usually either is or becomes one, especially if Kira is clearly manipulating the Eyes player to do his bidding.
** Bonus points for writing your own name in the Death Note set for a time past the end of the game (say, 7:00 AM) and then giving it to your Eyes and spending the rest of the round skulking while they kill everyone, since now they can't backstab you and write your own name in.
* ManipulativeBastard: Many killers pull this one.
* MeleeATrois: Make a few wild accusations. The players will immediately divide into those who believe you, those who don't believe you, and the real killer.
* MindRape: Could happen in any mode, but Misuterii's Umineko Mode almost relies entirely on this.
* TheMole: In a good-sized game, someone besides Eyes will be helping Kira.
** ReverseMole: Unless they're not.
*** [[MindScrew But if they're good,]] [[ParanoiaFuel you can never tell if they're one or the other.]] Often, [[WildCard they themselves haven't decided who they're really working for until the crunch comes]], [[TheStarscream and many will prepare for either outcome]].
* MoralDissonance: A good way to catch Kira is to pretend to be the Eyes, and vice-versa. This usually leads to all but you and your prey dead, followed quickly by your prey's death.
* MyDeathIsJustTheBeginning / ThanatosGambit: This can easily occur in Death Note mode if Kira is a sadistic prick or simply cannot worm his way out of the oncoming storm. As Kira, take your Death Note, hide it somewhere the Eyes will find it, fake your own death, and hide. The Eyes will gladly kill off the other players for you, only to find that you've written their name in the back of the book for 5:00 AM. Savvy tropers will note that this is a fair recreation of the actual plot of Manga/DeathNote.
* NamesToRunAwayFromReallyFast:
** Back when the game was a more cerebral experience, the announcement of certain players to play certain modes often triggered a mass exodus from the server.
** Others give themselves screennames that sound menacing, such as {{Yandere}}.
** When the update that allowed players to choose their own names and sprites was published, others would give their characters names that were ShoutOuts to dangerous characters in other media (such as the last name [[Manga/DeathNote Yamagi]].
* NeverSplitTheParty: You go it alone, and the killer will find you. Of course, if your "teammate" is the killer, you're screwed anyway.
* NinjaLooting: If you can justify it, an art form and a masterstroke RP. If not, you will be yelled at, insulted, and despised. Either way, a valid game tactic.
** Particularly if, as the Eyes, you loot a KO'd Kira.
* ObviousRulePatch: People who get the role of Kira have a tendency to rush to the office, check the student records, and write every name into the note, defeating the purpose of [[NeedleInAStackOfNeedles having several dozen extra names]]. Now the host has the option to disable computers completely.
** The security tapes seemed like a good idea when the game was starting out, but now that everyone and their mother knows how to rush the tapes in twenty seconds flat, a toggle was put in to disable them. Only after this toggle was put in did it become well-known that the tapes often lie.
* OneManArmy: Most of the time, the killer must try to manipulate the other players into killing each other. But not always. There have been examples of some clever masters of the combat system defeating as many as six enemies. [[{{Badass}} At the same time.]] In extreme cases, two of these may meet and keep on fighting for the whole round.
* ThePlan: Pretty much required for Kira or the Killer, sometimes turns into a GambitRoulette.
* PoorCommunicationKills: Boy does it ever.
* PowderKegCrowd: Inevitable. If you know which way the crowd will go when it goes off, you will win. If not, you will die.
* RefugeInAudacity: Nobody will kill you if you explicitly tell them you are Kira.
* ShoutOut:
** There are posters up all over the walls promoting Tsukihime, Melty Blood, TengenToppaGurrenLagann, [[CodeGeass Orange-kun's]] [[spoiler: fully upgraded form]] and the like.
** The blatantly-titled Death Note game mode.
** The help file has commentary from [[VisualNovel/Tsukihime Neco-Arc]].
** Some of the arsenal in the game include [[HigurashiNoNakuKoroNi a billhooked cleaver, a steel baseball bat, a taser]], the Manga/DeathNote, [[FireEmblem Alondite]], and the [[VisualNovel/{{Tsukihime}} 7th Holy Scripture]].
** There's also an item called a [[VideoGame/{{Touhou}} Mystia Coin, that lets you see in the dark.]]
** Sometimes, [[Anime/NeonGenesisEvangelion Ramiel]] randomly attacks the school (unless the host spawns him/them).
** The page image, which displays before the game starts, is a {{Higurashi}} shout-out. Most of the character sprites are HigurashiNoNakuKoroNi characters, as well.
** You can always play a ShoutOut of your own. This became much easier in Pyrce after the update allows you to choose your own name and sprite.
** In Misuterii, there is something called [[Anime/{{KillLaKill}} Rending Scissor Blade]] that one can make with the right materials.
* SchoolgirlLesbians: All the time - there are players who refuse to [=RP=] any other way. [[PsychoLesbian Sometimes]] the characters are sane.
* SomethingCompletelyDifferent: Nanaya Mode. No [=RPing=] this round, just KillEmAll, unless the host defies the trope by managing to get everyone under control before the round starts. When this happens, you often get a well roleplayed and interesting game. (Of course, it's still something completely different.)
* SpannerInTheWorks: Almost everyone who has been Kira or the Killer has constructed a brilliant plan only to have one person completely ruin it, often without realization.
* SpiritualSuccessor: to ''VideoGame/SpaceStation13''.
** Has its own in [[http://www.byond.com/games/MasterBraska/PyrceHigh Pyrce High]], which is even based on its code.
* SprintMeter: Which is drained by using (or being hit by wooden) weapons and running. When the meter runs to 0% or below, your character faints for a short while.
* TheStarscream: Many Eyes players turn on Kira at the first opportunity and steal the Note for themselves.
* SunglassesAtNight: While you are inside a building with lights the entire game, the lights can be switched off.
** "SUNGLASSES. IN. DARK"
* SurroundedByIdiots: Yes, you are. Bad [=RPers=] and good [=RPers=] [=RPing=] as idiots. In character wise, this often happens as well.
* TenLittleMurderVictims
* TheChessmaster: Kira pretty much needs to be one of these in order to win.
* TheHunterBecomesTheHunted: The students can always hunt down the killer, if they are better armed of course.
* ThereCanBeOnlyOne: "[[color:red 'Warning: Nanaya test sequences about to begin. Any staff still present in the building should vacate immediately. For test subjects in the building, your purpose is simple; if you wish to become the new 'Nanaya', or simply wish to live, kill everyone but yourself. That is all.'']]"
* UnwittingPawn: You have ''no'' idea. Especially likely to happen when there's a personal relationship between the two players.
* VideoGameCaringPotential: The killer has a tendency to choose one student (of their preferred gender) and spare them. This doesn't always happen, mind you, but more often than you'd think.
* VideoGameCrueltyPotential: Again, with real people, far more common than the trope above.
* WoundedGazelleGambit: Some killers will say that their (dead) victim attacked them first when another student asks about their bloody clothes.
* YouKillItYouBoughtIt: When Kira gets killed, it's ''extremely'' common to see another player take up the Note and become the next Kira. Sometimes invoked when Kira's player has things to do [[RealLifeWritesThePlot in the real world]].
* ZombieApocalypse: Zombie Mode, apart from the rounds when nobody is turned before the original zombie is dead.
