''Jack Frost'' (잭 프로스트) is an ongoing manhwa series by Jinho Go (고진호). It follows the story of Noh-A Joo, the new student at Amityville High School. Things start off rather poorly for Noh-A as she quickly comes to realize that the school is not as it appears. Caught in an interschool war between vampires, monsters, and other creatures, she must quickly learn what her new role is as the "mirror image," and how to handle the weird nurse Jin, the mysterious Jack Frost and his boss, Helmina. [[note]]In all seriousness though, Jack Frost and ''Manga/{{Hellsing}}'' have strong superficial similarities, but diverge later on.[[/note]]

What is known about Amityville: There have been 13 wars/classes, only Jack has survived them all. There are 4 districts North, East, South, West, and north is smallest. The combined population of the 4 districts is equal to a country in the living world. Those who come there are removed from the karmic cycle of death and rebirth, thus death is truly final there with no hope of any reincarnation or afterlife. There have been multiple statements hinting that the mirror image is somehow able to change this.

Not to be confused with the ''JackFrost'' films ([[NamesTheSame any of them]]) or [[Franchise/ShinMegamiTensei the demon]] [[VerbalTic that goes hee-ho!]].

* AbsurdlyPowerfulStudentCouncil: The heads of the four districts.
* ActionGirl / DarkActionGirl: Eva, another death god. We're not yet sure if she's evil. Also, Jin.

* BadassGrandpa: Omu.
* BadassLongcoat: The Devil Thread. IT GROWS [[BladeBelowTheShoulder BLADES!!!]]

** Ethan.

* [[spoiler:DrivenToSuicide: She jumped from a skyscraper.]]

* EmotionlessGirl: Jin, who may in fact be an [[RobotGirl android]].

* TheGunslinger: [[spoiler: Jin, previously.]] [[CrouchingMoronHiddenBadass Hansen]] as well.

* HospitalHottie: Jin, the North District school nurse.

* LastOfHisKind: Maru, the last Unicorn.
* LosingYourHead: Noh-A, frequently.
** Avid after [[spoiler: Jack beats him.]]
* MacGuffinGirl: Noh-A, again. Part of the plot is figuring out why she's important and what the world of the dead wants with her.
* MaleGaze: You will not ignore Helmina when she is in panel. This is a fact.
* MeaningfulName: Somehow, Jack has the same name as the [[spoiler: ONLY, as he died shortly afterwards]] doll Noh-A received from her father.
* {{Meganekko}}: Helmina.
* MindRape: Anyone who is bitten by a vampire must face their greatest fear. [[spoiler: Doesn't stop Jack, though.]]

* PantyShot: Noh-A and Eva.
** Helmina spends most of Vol. 4 parading around in her panties and [[StockingFiller garters]] for all to see. Of course, being ''[[MagnificentBitch Helmina,]]'' she shows absolutely no signs of giving a crap.
* PetTheDog: Helmina gets a few in Hansen's backstory. There's also Ji-hon's attitude to Eva.
* PsychoForHire: Guess.
* RapunzelHair: Helmina.
* RefugeInAudacity: [[LargeHam Helmina]] uses Jack to challenge EVERYBODY in the other districts. They're all frightened, except for the other heads of the districts, who are ''impressed.''

* ReplacementGoldfish: [[spoiler:Helmina]] looks just like Agathe, [[spoiler:Hansen's lover before she was killed.]]
* RuleOfCool: But, of course.
* RunningGag: Noh-A's decapitations and pantyshots, Hansen's masochism, Helena's sadism, Jin ignoring the last two.
* SadisticChoice: Jack receives one in the first book: back off or Avid makes Noh-A a vampire. Played for BlackComedy. Played completely for drama when [[spoiler:Ethan holds Noh-A's father's soul hostage unless she joins the East.]]
* SempaiKohai: Or "Sunbei and Hubei." Jack says this to Avid. [[CasualDangerDialog He is, of course, joking.]]

* [[spoiler:SnowMeansDeath: Noh-A's father bleeds to death in the snow [[HarmfulToMinors in front of her.]]]]
* StepfordSmiler: [[spoiler:Hansen and Noh-A.]] Type A.
* TallDarkAndSnarky: Jack, when he's not making {{nightmare face}}s.
* WhamEpisode: Chapt. 19:[[spoiler:Noh-A committed suicide because she's a DoomMagnet.]]
** Chapt. 21: [[spoiler:Jin is from the South, she was sent to kill Jack and Helmina and Siegfried is her former lover.]]
** Chapts. 28 and 29: [[spoiler:Hansen is the sole survivor of a vampire massacre Camilla initiated to feed Avid. And Kay, his brother who was killed in said massacre, is alive. And pissed.]]
** Chapt. 37.
* WhenSheSmiles: Noh-A's pretty cute when she smiles.
** Jack's a inversion: When he smiles, [[SlasherSmile he's more frightening than ever.]] When he frowns, however, he's damn near {{Bishonen}}.
* ZombieApocalypse: Besides suffering MindRape, Avid's victims also rise as vampire zombies.
