[[http://inbirth.info/ Under Night In-Birth]] is a HD 2D FightingGame made by French Bread, the makers of Videogame/MeltyBlood, released on September 20, 2012 in arcades. [[http://gematsu.com/2014/04/night-birth-coming-ps3-japan-july It will receive a PS3 port in July 2014]], and [[http://shoryuken.com/2014/07/04/aksys-games-bringing-under-night-in-birth-exelate-to-north-america-in-2015/ will be localized at 2015]]. French Bread is also upgrading the game in arcades under the title of ''Under Night In-Birth Exe:Late'', which rebalances the roster, features updated HD graphics and adds several new characters such as Chaos and [[VideoGame/AkatsukiBlitzkampf Akatsuki]].

The game is shaping up to be the SpiritualSuccessor of the Melty Blood series, in the same vein of VideoGame/BlazBlue to GuiltyGear just without the {{VisualNovel/Tsukihime}} characters and mythos, although it does feature [[Videogame/MeltyBlood Eltnum]]. You can expect the characters to be heavily story-driven this way, though.
%% It also features OneHitKill, in the same vein of those ArcSystemWorks games.

The roster include so far:
* Hyde: Possibly TheHero of the series. Wields a long sword.
* Linne: CuteBruiser who wields a knife and a long sword.
* Waldstein: Hulking white [[AnimeHair Anime Haired]] giant who wields giant [[SpiderMan Dr. Octopus-like]] tentacles as glove extension, [[WrestlerInAllOfUs he is the resident grappler]].
* Carmine: AxCrazy dude who fights by [[BloodyMurder manipulating his own blood]].
* Orie: Blue-haired LadyOfWar fighting with a rapier and a [[Manga/JoJosBizarreAdventure Stand]]-like entity.
* Gordeau: A stylish man in dark purple coat, able to summon a huge [[SinisterScythe scythe]] out of whim.
* Merkava: An... alien-like creature bearing resemblance to [[Anime/NeonGenesisEvangelion Angels of Evangelion]].
* Vatista: TokenMiniMoe, floats and fighting people with magic
* Seth: Cold, brooding young assassin who fights like a ninja and wields two daggers.
* Yuzuriha: Busty, boisterous oriental lady who fights with a long-ass katana.
* Hilda: WingedHumanoid, possibly the BigBad
* Eltnum: GuestFighter from "[[VideoGame/MeltyBlood a certain town]]".
* Chaos: An unknown [[TheBeastmaster Beast Master]], happens to have a relation to both Hilda and Gordeau.
* Akatsuki: GuestFighter, whom is also [[VideoGame/AkatsukiBlitzkampf a long way from home]]

The console version boasts a few new exclusive characters:
* Nanase: A young schoolgirl who wields a broad sword and seemingly connected with Hyde.
* Byakuya: An enigmatic young man with CrossdressingVoice and controls multiple floating swords as his weapon.


!1st Clause. DIVIDE.
* AlwaysNight
* BadassLongcoat: Gordeau's purple duster, and Seth's black trenchcoat.
* {{BFS}}: Yuzuriha's katana is REALLY long. Likewise, Gordeau's scythe is massive.
* BigBad: Hilda.
* {{Bishounen}}: Hyde and Seth.
* BloodKnight: Carmine
* BloodyMurder: Carmine is shown to fight by using his own blood.
* CastFromHitPoints Carmine is also shown to use attacks that drain from his HP, he can heal via a grab.
* CastingAShadow: Both Hyde and Seth. Gordeau also has a few darkness-like attacks
* CoatCape: Yuzuriha.
* CoolSword: Hyde has this.
** Also, Orie and Yuzuriha.
* DarkIsNotEvil: Despite his appearance, attitude, and job as an Assassin, Seth is the game's AntiHero.
* {{Expy}}: Hyde has the hair-style of [[VideoGame/BlazBlue Ragna the Bloodedge]], the fighting stance of [[Persona4Arena Yu Narukami]], and his sword general fighting style brings to mind [[Manga/{{Bleach}} Ichigo Kurosaki]].
** Speaking of Narukami... newcomer Byakuya is often said to have a paler but similar face with Narukami... with [[VideoGame/BlazBlue Nu's floating swords]].
** Gordeau himself has very similar look with [[Videogame/ArtOfFighting Robert Garcia]] per his appearance in ''VideoGame/NeoGeoBattleColiseum''
** Chaos bares a passing visual resemblance to {{Persona 3}}'s [[Persona4Arena Elizabeth]].
* FashionableAsymmetry: Seth and Hilda.
* GenkiGirl: Yuzuriha, if the notes that come out of her sprite during battle are any indication.
* GratuitousEnglish: Just like [[Videogame/MeltyBlood its predecessor]], if not worse.
** Gordeau is, aside from the name and menus, the most notable example. GURIIMU REEPAAH! MORTARU SURAIDO!
** "FIRST CLAUSE! DIVIDE!"
** "DOWN! DEPLETION OF EXS!"
** "BREAKDOWN! VANISHMENT OF VOID!"
** Orie goes for PunctuatedForEmphasis for her super: "REST! IN! PEACE!"
* GuestFighter: {{Videogame/Melty Blood}}'s Sion Eltnam Atlasia? [[spoiler: Technically, Eltnum is (more or less) Sion Eltnam Atlasia in an AlternateUniverse. She is subject to the same events as in Melty Blood, with most of Sion Eltnam Atlasia's back-story (and a massive design change). It should be noted that Eltnum is said to be intruding on the events of [=UNiB=].]]
** Played far straighter with [[VideoGame/AkatsukiBlitzkampf Akatsuki.]]
* {{Homage}}
** Because of her existence, there are a few thing from Eltnum that pay Homage to her ten years as a combatant in [[MeltyBlood MelBlo]]...
*** BootstrappedTheme[=/=]CrowningMusicofAwesome: Her theme being the biggest one. A remix of Blood Drain, Melty Blood Actress Again's title theme.
*** [[spoiler: There is also the small fact that Eltnum [[LeaningOnTheFourthWall lives on the Forth Wall]] in story mode, having fought for ten years... she sees herself as viewing how the "next generation" stacks to herself. As such, she views her relationships with other characters as something of a SempaiKohai relationship, especially with Hyde. [[{{Cloudcuckoolander}} Just about everyone brushes her off as insane]].]]
*** And [[spoiler: She is finally free of that Goddamn [[{{Nasuverse}} Shroom]] (read one: Kinoko Nasu) in her ending.]]
** Well, he is here... so you can't just summon the [[VideoGame/AkatsukiBlitzkampf Blitz motor user]] with out some references to his struggle.
*** BootstrappedTheme[=/=]CrowningMusicofAwesome: The theme that accompanies Akatsuki isn't his own, similar to Eltnum... War Start -Again- is a remix of title theme to AkatsukiBlitzkampf.
* HumanoidAbomination: Merkava. Most of the other Void probably qualify as well.
* IaijutsuPractitioner: Yuzuriha. With a {{BFS}} no less.
* KatanasAreJustBetter: Yuzuriha's got one nice katana. Hyde's swors is also a katana
* KnifeNut: Seth
* LadyOfWar: Orie is pretty much checking every list of requirements of this trope. Yuzuriha's fighting style is also pretty graceful, but she's more [[GenkiGirl energetic]] than most examples.
* MightyGlacier: Waldstein
* MultiColouredHair: Both Hyde and Seth. Hyde's is black and blond, while Seth's is black and white.
* LightEmUp: Orie
** YinYangBomb: Hilda
* NamesTheSame: Do not confuse Vatista with {{Batista}}
* NoblewomansLaugh: Hilda, of course.
* OneHandedZweihander: How Gordeau wields his SinisterScythe.
%% * OneHitKill: They are called "Infinite Words EXS" (Pronounced "Exist").
* PowerDyesYourHair: Carmine's hair starts out white, but turns red when he activates his powers.
* RatedMForManly: Gordeau certainly looks the part.
* RedOniBlueOni: Hyde and Seth respectively. There's also the blue-haired [[LadyOfWar Orie]] and the redhead [[GenkiGirl Yuzuriha]]. Carmine and Gordeau also exhibit this trope in the former's Arcade Story.
* TheRival: Seth to Hyde, at least according to the intro and a few promotional materials.
* SinisterScythe: Gordeau has this... [[HyperspaceArsenal notice that he's pulling it out of thin air]]
* TokenMiniMoe: Vatista
** ElegantGothicLolita
** LittleMissBadass
* WalkingShirtlessScene: Gordeau
** NoShirtLongJacket
* TheWorfEffect: In Orie's Arcade mode, [[spoiler:Merkava comes in out of nowhere after [[FinalBoss Hilda]] is defeated, and devours/kills her before fighting Orie himself.]]
* WrestlerInAllOfUs: Waldstein, and to some degree Merkava.
* ZettaiRyouiki: Linne and Orie. There's also Eltnum, natch.
