When a teacher is killed in Mitadake High School, the school's security system automatically places the building on lock-down, preventing anyone from entering or leaving...including the murderer.

Mitadake Saga was a {{webcomic}} hosted on Website/ComicFury. It was based on the Byond game, VideoGame/MitadakeHigh, by Devourerofsouls, which pays homage to many animé and their stereotypes.
There were plans for three overall story arcs
* ''Death Note Mode''
* ''Duo''
* ''Terminus''

As you can probably work out from the first subtitle, the first arc was related to ''Manga/DeathNote''. The Byond game has a Death Note mode which replaces the killer with Kira and adds a player who has Shinigami eyes. This arc ended in March 2011.

''Duo'' was to be based on the normal mode of the game. ''Terminus'' was a secret. A prequel arc, called ''Prelude'', was planned to go in between ''Duo'' and ''Terminus'', but it was cancelled after the creator decided that it'd make the project too long, and was too light-hearted in comparison to the other arcs.

Unfortunately the comic has vanished from the internet and the site it was hosted on has been deliberately excluded from the Website/InternetArchive making this comic most likely LostForever.

!!''Mitadake Saga'' provided examples of:
* ABloodyMess: Inverted and invoked. The Silver Haired Girl notes that the school's ketchup is odd, drawing attention to how it is drawn just like blood. In the original game ketchup could be used to make fake blood, so there's a good chance this trope will be played straight later.
* AdventuresInComaLand: Potentially. [[spoiler: Zero is knocked out whilst fighting Keiichi and finds himself in an entirely white expanse of nothing, with no-one but him and his dead friend Zaraki around. However, whether it's really happening is debatable, as Yuki (and all the other dead students) suddenly appear too. Not to mention that when Zero gets back to reality, the "ghosts of all the dead student appear in front of Keiichi and protect Zero, but that could easily be down to Keiichi's own delusions, as he seems quite insane by that point.]]
* AnimeHair: Expected, considering both the comic and game's nature
* ArtEvolution: The earlier art is very iffy. It continued to improve over time, with increasingly complex backgrounds, more distinct character designs, and softer shading effects.
* [[AscendedFanboy Ascended Fangirl]]: The comic's co-author, Espeh, was recruited to work on the project after her and Frosty met at college, and she contributed some good ideas.
* AxesAtSchool: Kazu Ito is carrying around an axe. Hmm...
* BigNo: Keiichi lets out a huge one stretching across several panels right before [[spoiler: his death.]] One panel even has it written scattered around alphabet soup-style amid a rain of hoarded keys.
** {{Lampshaded}} by the Author's Notes underneath: Trope Unlocked: Big No
* BlindingBangs: Keiichi Hideki's hair completely obscures his eyes
* BloodFromTheMouth: [[spoiler: Koji]] coughs up blood upon being stabbed
* TheCameo: Appropriately enough, three characters from the actual ''Manga/DeathNote'' series appear during that arc, though mostly off-panel.
* TheChessmaster: In the Kira arc, [[spoiler: Keiichi Hideki takes the opportunity presented by the lockdown to test out the finer points of using the Death Note, by manipulating Kazu Ito into killing two people. All without writing his name in the book itself.]]
* ClosedCircle: The automatic lockdown provides this.
* TheCorpseStopsHere
* DeadManWriting: [[spoiler: Zero receives a message from the Late-Daichi at the end of Chapter three.]]
* [[EventFlag Death Flag]]: During the Kira arc, several characters InfoDump about their pasts, perhaps unintentionally giving the impression they're collecting Death Flags.
* DecoyProtagonist: [[spoiler: Zaraki Yagami looks to be the protagonist, especially considering his goggles, but is killed by Kira fairly early on]].
* DrivenToSuicide: [[spoiler: Daichi Takana's mother was swindled by Mai Saito's father, causing her company to go bankrupt, leading to her suicide. Oh dear...]]
* DroppedABridgeOnHim: A few characters have gotten this treatment. [[spoiler: Zaraki Yagami was the first one introduced and was also the first one killed in the comic. Mai Saito was also killed only 12 pages after she was introduced. AnyoneCanDie indeed...]]
* EasilyForgiven: Kazu [[spoiler: kills Daichi because he thought he was Kira.]] Zero and Koji accept this excuse a little too easily. Then again, there wasn't really time to have a calm discussion about it after he finally finished explaining why he did it.
* EveryoneIsASuspect: The whole premise.
* EvilGloating: Kira engages in this throughout the final chapter of the Death Note arc.
* ForTheEvulz: At the end of the Death Note arc, it's revealed part of the tragedy occured because [[spoiler: Ryuk was bored]].
* {{Foreshadowing}}: Reread through the comic and you can catch some subtle hints that you probably didn't notice before.
* FreudianExcuse: Kira's motivation is revealed in a set of silent panels, apparently, [[spoiler: his mother went insane after being the victim of a violent crime]]. Too bad they [[JumpingOffTheSlipperySlope took a flying leap off the slippery slope]].
* GogglesDoNothing: Zaraki Yagami - The Boy With Goggles - funnily enough, wears goggles. In the original game, this is reference to protagonists who wear goggles. Here it's...
* HoistByHisOwnPetard: In the first arc, [[spoiler: Kira is killed by the Death Note]].
* HollywoodHacking: Nana uses this to retrieve the code for the security room from the computer lab.
* InJoke: The actions of some of the characters is a nudge at the constant rulebreaking and metagaming found in the original game.
* InfoDump: Frequently in the first arc.
* [[spoiler: KillTheCutie: Poor Yuki...]]
* KilledOffForReal: Anyone who dies. [[spoiler: Although, a transparent Zaraki did pop up during Zero's fight with Koji.]]
* LateToTheTragedy: Done with a slight twist; Duo's Prologue revealed that [[spoiler: Shiki ''almost'' got back into the school before it was locked down, but since she'd watched a show back home first, she was ''just'' outside and had the doors slam shut in her face.]]
* ManipulativeBastard: The first arc's Kira.
* Meganekko: Aki Mishiba, the purple-haired girl.
* MoodKiller: In Duo's Prologue, Taku butts into a conversation about what happened in the Kira arc before it can really get started.
* MurderIsTheBestSolution: Considering the source game, this occurs a lot.
* MyGodWhatHaveIDone: [[spoiler: Kazu]] has this when he realizes the people he killed were innocent.
* NightmareFetishist: Mizue, who excitedly wants to examine a dead body when the Lockdown occurs.
* NoSocialSkills: Duo introduces Taku, the Gray Haired Boy, as somebody ''really'' interested in what happened during the first arc. And who constantly bugs [[spoiler: the sole survivor]] about what happened. With no regard to their SurvivorGuilt or anything. His utter lack of tact makes him come off as a {{Jerkass}}.
* OntologicalMystery: The school could count, once the lockdown is activated, especially as it's implied that there's more to it than it would seem...
* OtakuSurrogate: Quite a few, especially Zaraki.
* RedHerring: The scene between Zero, Zaraki, Daichi and Mai early on in the story where everyone introduces themselves. [[spoiler: Kira gets their names from other sources, but that doesn't stop the characters accusing each other over it]]
* RetCon: [[spoiler: Keiichi's motives and plans are fairly different from the Kira Monolouge in the third page.]]
* TheScapegoat: Kira was planning to set up [[spoiler: poor Yuki]] as this.
* ScarsAreForever: In the second arc, [[spoiler: Zero has a scar over one of his eyes]].
* SeeYouInHell: Uttered by Koji [[spoiler: as he's about to finish off Zero, right before getting attacked from behind.]]
* ShyBlueHairedGirl: Mai Saito seems to be fairly shy.
* SerialKillingsSpecificTarget: [[spoiler: This is Keiichi's motivation in slaughtering the other students in the school, because he doesn't want the Kira Investigation Force to know he realized that they sent an undercover FBI agent to the school]].
* ShoutOut: A fair few, though this is likely to increase as the series continues.
** Examples; ''Manga/DeathNote'', ''VisualNovel/HigurashiWhenTheyCry'', ''VisualNovel/{{Tsukihime}}''.
* SpannerInTheWorks: [[spoiler: Keiichi]] really hadn't been expecting [[spoiler: Yuki to survive his attack and write his name in the Death Note]].
* SpitefulSpit: Performed by [[spoiler: Yuki to Keiichi, moments before being finished off fog good after he reveals he had been lying to her all along.]]
* [[spoiler: SoleSurvivor]]: In the Kira arc.
* SunglassesAtNight: Fairly redundant because they're inside anyway. Not that that makes them any more practical. Kazu Ito wears them.
* SurvivorGuilt
* TwistEnding: [[spoiler: Yuki, thought to be dead, manages to write Keiichi's name in the Death Note, Shiki is waiting outside the school and Ryuk gave Yuki her Shinigami Eyes out of boredom]].
* {{Yandere}}: Miki is this for her brother, Koji.
* YouBastard: Taku's cheerful attitude about all the murder and mayhem going on comes off as casually cruel to his classmates... but is a good translation of ''Mitadake High'' players who don't bother acting like normal teenagers caught in such a situation would.
* YouGottaHaveBlueHair: Two characters have blue hair. They're easy to confuse for each other, which makes the fact that they interact with each other very early on, somewhat awkward.
** Almost everyone in the cast has an implausible hair colour, ranging from blue, green, purple, pink etc. There are some ordinary hair colours, like brown, black and blonde in there too, so there's a healthy balance.
* YouHaveOutlivedYourUsefulness: In the Death Note arc, [[spoiler: Yuki and Kazu]] fall victim to this.
