[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/crepuscule-part_ii_tvtropes_2050.png]]''Crepuscule'' is an ongoing Korean webtoon by Mirchi and Yamchi, and follows the story of Lark Alfen living in an alternate world where monsters live and lead fairly normal lives.

The story begins with 5-year old Lark being bullied for his red eyes, which are said to be those of a monster's. Then, one day he meets Setz, a pureblood vampire who shares the same eye color and becomes his friend. When Lark finds out that he is to be sent away, Setz decides to bring Lark back home with him. Of course, the said home is in Crepuscule, where vampires, succubus, ghosts, zombies, and werewolves live, which makes Lark's identity as a human a bit of a problem.

Note that there are two versions of the story, with the older, canceled edition being penned by [=TieRo=] and muchi.

!!''Crepuscule'' provides examples of:
* AbsurdlyPowerfulStudentCouncil: Consisting of Setz, Karne, Neal, Bathory, and Sai.
* AbusiveParents: Navarus. [[spoiler:Although Setz is officially his adopted son]]. Karne's mother was also less than kind to her while alive.
* AllLoveIsUnrequited: So far, the list goes:
** [[spoiler: Carne -> Setz, Setz did care for her deeply though and they were engaged. It was possible for this couple that it would have been subverted, but then Carne died.]]
** [[spoiler:Sai -> Bathory, Sai joined the student council for Bathory. She treats him as an annoyance at best]]
** [[spoiler:Sia -> Seere, Seere is more focused on Lark then Sia, and he knows it.]]
** [[spoiler:Sylvia -> Navarus, Sylvia dedicates her life for him, but realizes he'll never return her feelings because of his wife. Navarus was furious at Sylvia for killing Angela and seems to view her as worthless.]]
* AllOfTheOtherReindeer: Lark, who was bullied for having red eyes. [[spoiler:Nergal]] was also bullied heavily for being a werewolf with no physical strength.
* ApologeticAttacker: Riu, while beating up [[spoiler:Setz]].
* ArrangedMarriage: Setz and Karne are in one. Has some shades of PerfectlyArrangedMarriage, as Karne does fall in love with Setz, and while Setz's feelings might be more platonic than romantic, he genuinely cares for Karne as well. [[spoiler: shame about her powers going berzerk...]]
* AxCrazy: Neal.
* BattleButler: Riu.
* BecauseYouWereNiceToMe: The basis of Sia's crush on Seere. As well as why he's friends with Lark.
* BewareTheNiceOnes: Karne. Setz as well as a child, once furious enough at Neal that he might've seriously killed him.
* TheBerserker: Those that fall into a rampage are this. With the added bonus of getting a huge boost in power and blood lust. They died at the end of their rampage though.
* BlessedWithSuck: Sia has remarkable endurance and low sensitivity to pain. However, his general lack of senses has also led him to finding life to be incredibly dull, hence why he'd rather just sleep all day.
* BookDumb: Lark, who ends up failing all his exams. Once can assume Sai is this as well, as he's failed for three years and is thus still in school.
* BreakTheCutie: Setz, thanks to [[AbusiveParents Navarus]], which Angela predicted would happen. Karne as well, thanks to [[ManipulativeBastard Neal, emphasis on the bastard]].
* BrilliantButLazy: Sia.
* BrokenBird: As of recent chapters, this seems to be the case with [[spoiler:Bathory]], though now that [[spoiler:she's found Angela, her only surviving relative, she seems to be on the mend. But with Angela's death, she back to broken.]]
* ChekhovsGunman: [[spoiler:That white fox Lark was caring for in the beginning? It's Nergal, the first generation pureblood werewolf who governs the land of the same name.]]
* ConvenientlyAnOrphan: Lark's foster parents weren't exactly nice either which is why he decided to go over to the other world.
* CoolBigSis: Bathory wants to be this to Setz and Lark. They're... not as enthusiastic about the idea.
* CreepyChild: Those two jerkass Elders.
* CuteLittleFangs: Setz and Bathory, notably.
* DarkerAndEdgier: Part 2 as a whole. [[spoiler:Part One was mostly Lark's entering the school. It had its dark moments, but they were usually countered with comedy the next chapter. At the start of Part 2, Angela is killed and it just gets darker from there.]]
* DefrostingIceKing: Setz.
* DiedInYourArmsTonight: [[spoiler:Karne, in Setz's]].
* DisappearsIntoLight: [[spoiler:Karne]].
* DreamStealer: [[spoiler:Bathory]] can't actually steal dreams but she can use the dreams to steal information from the target's minds.
* EmotionlessBoy: Sia.
* EvilTwin / SuperPoweredEvilSide: There's a sinister-looking guy who appears in Lark's dreams that looks exactly like him. He claims to be [[spoiler: Vlad Tepes, a powerful vampire who opposed the succubus' dream world idea]]. Later on, [[spoiler: he tells Lark who killed Angela and gives (or unlocks) Lark's powers over light. Strangely, the real Tepes looked nothing like Lark (and is actually a woman)]].
* EyeScream: To Neal (Nirvana). Twice.
* FeelNoPain: Sia.
* FemmeFatalons[=/=]WolverineClaws: Setz, although this is said to be common to pureblood vampires, not a unique ability.
* FriendlessBackground: Lark, before meeting Setz. Sia, likewise, had no friends before Seere and Lark, due to his personality. For that matter, Setz too, depending on whether or not you count Carne as a 'friend'.
* FriendlyNeighborhoodVampire: Setz, Angela, and some others.
* GoOutWithASmile: [[spoiler:Carne]].
* GoodWingsEvilWings: Karne.
* HealingFactor: Sia.
* IWantMyBelovedToBeHappy: [[spoiler: Sylvia, Navarius' werewolf subordinate, wants her master's plans to succeed so badly she murders Angela because she thinks she betrayed him.]]
* IdiotHero: Lark. Jusified, as a human he naturally is weaker than the vampires and wouldn't be able to use their magic. As well as coming from the rural area, his education is no where as extensive as the other students that are members of nobility.
* IcePerson: Gilles de Rais.
* IJustWantToBeNormal: Lark, due to his bullying in the human world, realizes this. An interesting variation in that he lives in the vampire world and in order to fit in with the vampires, he need to be special as a human.
* ImmortalImmaturity: The most extreme form is the two council members who look like children and are [[KidsAreCruel just as vicious]].
* InnocentlyInsensitive: Lark ''meant'' well when he told Setz that he'd actually forgotten about him in a "so don't worry about having abandoned me" way, which Setz knew, but it still hurt him pretty badly.
* InterspeciesRomance: Really nearly everyone in the series is a mix.
* {{Irony}}: Setz hates his dad for being cold and absent without knowing he's taking on tremendous burdens to protect his loved ones; a few years later Setz is doing the exact same thing ''and he still doesn't understand his father''.
* KidsAreCruel: Lark was frequently bullied by other kids for having red eyes.
* KickTheDog: Neal does this repeatedly. [[spoiler:Lark]] begins to indulge it after [[spoiler:Angela's death]] as well, and for that matter, [[spoiler:Tepes]] when she brutally beats up [[spoiler:Sia]].
* KnightTemplar: The council.
* LightEmUp: [[spoiler: Lark's special power.]]
* LightIsNotGood: [[spoiler: the founder that had this power hated humans and wanted to kill them all, since Lark got it he has getting very unnerving to be around]]
* LikeFatherLikeSon: Setz hates that his father is distant, but it's due to him shouldering responsibilities (including people's lives) so great he doesn't care if he's hated. Of course Setz is already doing the same thing.
* LivingEmotionalCrutch: Setz to Karne.
* LonelyRichKid: Setz.
* ManipulativeBastard: Neal.
* MementoMacguffin: The ribbon Karne wears was a gift from Setz, as well as belonging to his late mother. [[spoiler:It's also all that remains after she disappears]].
* NamedAfterSomebodyFamous: Vlad Tepes and Guilles de Rais.
* [[spoiler: NeverFoundTheBody: Angela's, but it's been made clear she's DeadForReal. Probably.]]
* OurMonstersAreDifferent:
** OurGhostsAreDifferent: Bathory is half succubus and half ghost.
** OurVampiresAreDifferent: Vampires were once closer to the typical image of a vampire, but when the race started dying out they began breeding with other demons. The vampiric blood was strong enough to blot out characteristics of the other demons, until they were all considered vampires instead.
** OurWerewolvesAreDifferent: They look like CatGirl[=s=] and they can be foxes too.
** OurZombiesAreDifferent: They're not undead, just oddly colored, exceptionally tough, and resistant to magic.
* TheQuietOne: Sia, due to finding talking bothersome.
* ParentalSubstitute: Angela to Lark.
* PerpetualFrowner: Excluding his time as a child, you can probably count on one hand the number of times Setz smiles or even as so much ''smirks'' in the first hundred chapters.
* PetTheDog: The one person Navarus seems to actually care about is Carne--possibly due to his friendship with her late father.
* PlayingWithFire: Karne.
* PoorCommunicationKills: [[spoiler:Carne attempts to prove to herself that he'll care for her despite knowing that she killed his mother--except because she worded it vaguely, Setz thought she was talking about ''his'' secret and reacted poorly. He then apologized, leading her to think that he was rejecting her, [[UnstoppableRage and then]], [[DiedInYourArmsTonight well]]...]]
* Really700YearsOld: [[spoiler:Bathory is far too old to be a student]]. Similarly, all first generation characters are this. [[spoiler: Neal/Nilvana is apparently much older than he appears too. Arguably Setz, technically he is only 16 but he was in his mother womb for 500 years.]]
* RedEyesTakeWarning: Red eyes are the sure sign of a vampire in both worlds, and Lark's constant bullying is due to him having red eyes.
** [[JustifiedTrope Justified]] because a pact made between humans and vampires made it impossible for humans to have red eyes, and impossible for vampires to breed with humans. Which in turn raises a question about Lark's ancestry, because he can't have red eyes as a human (which he does have) since only vampires can have red eyes, and he is definitely a human (and can't be half-human, half-vampire).
** The author had a handy chart of which types of eyes meant what (IE zombies have solid red eyes, werewolves have slitted pupils, ghosts have pinkish eyes) but there's been so much interbreeding it doesn't really matter.
* SelfMadeOrphan: [[spoiler:Karne, much to her horror]].
* ShoutOut: To SailorMoon
* SquishyWizard: Nergal.
* SternTeacher: Angela. Also qualifies as HotTeacher.
* TheStoic: Setz.
* SamusIsAGirl: [[spoiler: Vlad]] of all people!
* SpellMyNameWithAnS: Karne/Carne? Nirvana/Nilvana? Riu/Liu? And so on and so forth.
* StrangerInAStrangeSchool: Lark is a human attending a school for vampires.
* SugarAndIcePersonality:
** Setz who, while much colder than he was as a child, still remains a decent person at heart.
** Sia's also not the friendliest of people at first, but if you actually bother to get to know him ([[FriendlessBackground which most don't]]), he's a good guy.
* SuperSpeed: Riu, Nergal's secretary.
* TallDarkAndHandsome: Setz.
* TearsOfBlood: [[spoiler:Karne, during her rampage on the school in chapter 76.]]
* TeenGenius: Seere.
* ThemeTwinNaming: Millefeuille and Chocolat, the Meil Twins who are part of the Council, are named after sweets.
* TimeSkip: The first few chapters show Setz and Lark's childhood and meeting, basically acting as a prologue to the main story thereafter.
* TookALevelInJerkass: [[spoiler:Ever since Lark gained his ability, he became arrogant, cruel, and completely out of character, as others of noted. He talks down to Setz when he confronts Larks, and even goes so far as to beat up Sia nearly to death. This sudden change has personality may have more to do with [[DemonicPossession Tepes taking control]].]]
** He goes back to normal once [[spoiler:Tepes]] backs off. [[spoiler:Slightly, at least]].
* TranquilFury: [[spoiler: After Lark learns from Tepes who killed Angela and unlocks his light powers, he calmly blows up a building as a demonstration.]]
* TraumaInducedAmnesia:
** Karne, who initially doesn't remember much about the incident that killed her parents. [[spoiler:Namely, the fact that ''she'' caused it]].
** Given everything he's been through at [[spoiler: Navarius]]'s hands, it wouldn't be surprising if this is what happened to [[spoiler: Neal/Nilvana, who doesn't remember his sister]].
* UnstoppableRage: [[spoiler:Karne, after being pushed over the edge]].
* UsedToBeASweetKid: Setz. He got worse after the time skip, but he's still sweet [[SugarAndIcePersonality deep, deep down]].
* WhiteHairBlackHeart: Gilles and Nergal, both of whom can be vicious in obtaining their goals. Averted with Sia, however.
* WithGreatPowerComesGreatInsanity: What is gradually happening to [[spoiler:Lark]].
* {{Workaholic}}: Setz.
* {{Yandere}}: [[spoiler:Carne is one for Setz at her worst]].
