History Characters / UnderNightInBirthOriginalCast

* BaitAndSwitchBoss: In Orie's arcade mode, where she's fought before [[ArchEnemy Merkava]]. In Late[st] she's fought as the second to last opponent on Phonon's arcade mode, where she makes way for Nanase.
** She would've been this for Nanase herself, [[ButtMonkey except that the game makes it perfectly clear way before that point that Hyde will be the last opponent]].

** Hilda's initi

* InformedAttractiveness: A notable amount of characters call her cute, with Hilda going as far as to say she has a pretty face. They're not wrong, but she's not that different from the other females in the series.

* MechanicallyUnusualFighter: "Charge" moves are standard for several fighting game characters, but virtually all of Vatista's special moves are charge moves, with a few even being required for some of her most powerful combos, making her unusual in that her entire playstyle centers around charging up moves as she's using other ones.

* SayingSoundEffectsOutLoud: Vatista occasionally makes sounds when using her abilities, most notably her extremely cute "[[MoreDakka Ba ba ba ba]]" when using her force function finger bullets on the ground.

* StoneWall: Physically. Her unique trait nullifies the unique properties of counter hits landed on her (e.g. no extra wall/ground bouncing or OTG pickups). Averted with high-level Vatista players, her combos are quite possibly the hardest in the game but their damage is insane. With resources, she can nearly KO [[FragileSpeedster Seth]] from full hp in a single combo.

* DifficultButAwesome: Seth's incredible speed gives him plenty of combo options, but using him effectively requires proper timing, execution, and positioning as his health is still the lowest in the game and has little to no plus-frame moves that allow him to keep constant pressure without good knowledge on his blockstrings. Played well, he can rush his opponent down and burst down their health bar very quickly and maintain some unpredictable mix-ups. This can be taken up a level further where Seth is the only character in the game to have unblockable set-ups that can either range to a combo afterwards, or a long-chain of unblockable wake-up set ups with an orb in place to fully deplete an opponent's life bar should he have the corner, vorpal, and the meter to do so.

* GreenEyedMonster: Seth's grudge and rivalry with Hyde stems from the fact that Hyde recently became involved with the Hollow Night yet has everything Seth has ever desired and strove to obtain his entire life: the companionship of Linne, the weapon required to end her eternal curse, and the freedom from the Night Blade's oppressive burdens. Even with all of his powers Hyde refuses to kill Linne, making Seth believe Hyde isn't worthy of his gifts, leading to the Assassin antagonizing Hyde in order to take them for himself, which he supposedly achieves in his arcade ending.

* HourglassPlot: With Waldstein. Both are members of the Night Blade who are connected to Linne, with Seth trying to kill her to end her curse of reincarnation while Waldstein protects her as her guardian. However in Sys:Celes, the roles are reversed with Waldstein now after his ward to get her seal of reincarnation for Kuon's scheme while Seth works together with her to kill Kuon.

* ChildhoodFriend: To Hyde. She finds him very cute and affectionately refers to him as "Hyde-kyun". She seems to be a bit concerned about how he's grown into looking like a punk. They stopped seeing each other after Hyde did something that traumatized both of them, but their thoughts show that they both miss each other badly.
* ClothingCombat: She can use her coat in her attacks.

* GratuitousEnglish: Her jumping A had her exclaim "ELBOW!" while doing an elbow drop. No doubt that watching too much TV, possibly pro-wrestling shows, got Yuzuriha doing it.

* IWantMyBelovedToBeHappy: Yuzuriha mentions internally in her chronicle mode that she hopes Hyde has found some other girls to be with, but thinking about this causes her no small amount of emotional distress.

* MasterSwordswoman: Her family dojo practices the ancient Sougetsu Itto-ryu Battojutsu (roughly translating into Sougetsu One Blade Drawing Style) and Yuzuriha is no slouch in applying it in combat. Her movelist point out that the style's techniques are numbered.
** First Form: Paulownia- Yuzuriha's command normals functioning as a three-way slash that are weaker versions of her second form techniques.
** Second Form: Bloom- Yuzuriha's primary slashes that reach nearly 3/4ths of the screen and allow her to keep herself distanced while also letting her continue her combos if she lands a hit.
** Third Form: Sever- Yuzuriha's aforementioned Force Function that lets out an empowered slash that not only gives pause and then resumes her momentum if done in the air, it can also be charged to become an unblockable.

** Fifth Form: Vivid- A yet unseen technique that has Yuzuriha slash out a projectile. This is only conceptual as this move is found in the game's files but not usable.
** Secret Art: Luster Birth- Yuzuriha's Infinite Worth
** Zeroth Form: Life Crimson- Yuzuriha's Infinite Worth EXS
** Et Cetera: Multi-Layer Ring- A technique that is presumably of her own creation where she slashes out 8 simultaneous attacks in an orb like pattern behind her.

* NoodleIncident: With Hyde, both have yet to fully recover from it. Most of their inability to repair their friendship is fueled by Hyde's guilt since Yuzuriha knows that he's actively avoiding her. Because of this, she decides to let him be despite her wishes to see him again. At some point between the end of the first big Hollow Night and the start of the Final Night, Yuzu has seemingly rejoined Hyde's regular circle.

* SixthRanger: Has ostensibly joined up with Hyde's group to collectively help Linne and deal with Kuon after spending the first big Hollow Night on her lonesome.

* NoodleIncident: With Hyde, both have yet to fully recover from it. Most of their inability to repair their friendship is fueled by Hyde's guilt since Yuzuriha knows that he's actively avoiding her. Because of this, she decides to let him be despite her wishes to see him again.

* UnresolvedSexualTension: Her and Nanase's chronicle modes heavily imply that Yuzuriha and Hyde's relationship was definitely not heading in a platonic direction before the NoodleIncident that drove them apart. Both her and Hyde are still in a lot of emotional turmoil being caught between how badly they hurt each other and their wish to be close again.

* BenevolentBoss: She's very polite, friendly and cordial towards her subordinates most of the time. This even extends to those who left her organization, as she's still very friendly towards Gordeau. This however extends to being quite a few ways above being casual with her status as a leader and most of the work falls to Chaos. [[YouHaveOutlivedYourUsefulness This only lasts until she feels like she doesn't need someone anymore, as Gordeau and Chaos find out the hard way in their arcade modes]].

* BigBadWannabe: She's the final boss of the first game and it revolves around her plans to become a Rebirth, but is completely unaware that she's merely being used by Kuon. Adding insult to injury, unlike the rest of the cast, her theme transitions from "Overwhelm Despair" to "Relatively Despair" indicating how much of a threat she actually is compared to [[GreaterScopeVillain Kuon]].

* CastingAShadow: Her attacks are mostly darkness-based.

* {{Determinator}}: She is hellbent on becoming a Re-Birth, despite the protests of Hyde, Yuzuriha and even [[spoiler: Kuon]]. And if she fails and becomes a Void, then so be it.

* TheFriendNobodyLikes: Despite officially being their boss, none of the other members of Amnesia seem to actually like her. Chaos is infuriated with her when she just leaves Gordeau bleeding out in his Arcade Story, Enkidu spends most of his Chronicle episode internally snarking at how dumb she is, and Uzuki is annoyed by the prospect of taking orders from her. The only two people that seem to have any semblance of friendship with her are her fellow founders Gordeau and Roger, the former of whom quits the organization due to the latter's death.

* HatedByAll: The reason she's either the FinalBoss or ClimaxBoss of every character's Arcade story besides Enkidu's and her own; nobody wants to see her as a Re-Birth. It's been suggested that not even her own allies within Amnesia seem to like her that much or fully agree with her plan, and most of them have other reasons to be in the organization besides genuine loyalty to her.

* ShamelessFanserviceGirl: Hilda flirts with ''everyone''. The most shining example is her first encounter with Hyde. When she catches him staring at her chest, she starts dancing seductively and shows him even more skin.
* SlouchOfVillainy: She does this on a seat of darkness when using certain moves.

* SneezeCut: Is subject to this in Phonon's Arcade Route. When Phonon encounters Gordeau, he mentions how Phonon's faux-air of being a sadist reminds him of his friend and former boss, cue the scene quickly changing to Hilda sneezing in the Altar of Light and Darkness, and immediately back to Gordeau and Phonon.

* SuperPowerLottery: Her winning it so hard drove her crazy with power and is the only reason anyone cares about her existence. Her EXS allows her to teleport and craft some kind of black matter from nothing. It's so strong Gordeau doesn't think he has a good chance against her, even though she's not even that good at using her own powers.

* TheUnfought: Hilda isn't fought whatsoever in the Arcade stories for Enkidu and Londrekia. This can be chalked down to Enkidu simply having no interest in her and Londrekia's main priority being Orie and Wagner.
* UngratefulBitch: She attacks Chaos in his arcade mode even though all he wanted to do was get Gordeau medical attention, despite Chaos doing literally all her work and planning for her.

* YoungerThanTheyLook: In her early 20's suggested by her frequent visits to Gordeau's bar and collection of alcohol. She is said to be two or three years older than Yuzuriha, who is at least around ages 18-20.

** JerkWithAHeartOfGold: A ''very'' minor example. While he does find Azel annoying, he refuses to attack him due to his age, shows concern for his wellfare during the Hollow Night, and jokingly muses that he may have been too soft on him after they say their goodbyes.

** Vatista winds up receiving some with Kuon during her Arcade Mode, seeing that after living for centuries Kuon never forgot her face since she handed him the Insulator during the Licht Kreis war and would've preferred meeting under more ideal circumstances. They still have to clash because of the Aeon's ambitions, but its the thought that counts.

* VocalDissonance: Vatista in chronicle mode speaks without her MachineMonotone in a deeper voice that doesn't match her childish appearance at all and loses her quirky, NoSocialSkills robotic mannerisms. Her chronicle voice is almost completely unrecognizable from NaoTouyama's previous performance as Vatista in the Arcade mode stories and gameplay to the point that some thought a different voice actor was used. [[spoiler: It's implied that this is what Vatista sounds like in her true adult form with all seven wings. Hearing Vatista suddenly start speaking like this while she is still in her child form is odd, to say the least]].

Yuzuriha's Force Function is called '''Third Type: Sever''', which has her utilize a multi-hitting slashing technique that strikes out in front of her. She can enter her stance through this maneuver, allowing for her to return to a safe position, reapply pressure, or trick her opponent out by fully charging it to make it unblockable. UNI2 showcases another technique of her own design '''Et Cetera: Ten'I Muhou''' that has her performing a rising slash and putting her into air stance.\\\

* EndearinglyDorky: She's not very good at conversing with others, but not for lack of trying.

* WasOnceAMan: [[spoiler: If her win quotes in ''BlazBlueCrossTagBattle'' are true, then Vatista used to be an ordinary human before her soul was infused into her current body. She is aware of this process, but she doesn't remember whose soul was used to create her.]]

* PerpetualFrowner: While his work coat and off-work scarf covers his mouth, this is his most common expression.

* BigBadWannabe: She's the final boss of the first game and it revolves around her plans to become a Rebirth, but is completely unaware that she's merely being used by Kuon. Adding insult to injury, unlike the rest of the cast, her theme transitions from "Overwhelm Despair" to "Relative Despair" indicating how much of a threat she actually is compared to [[GreaterScopeVillain Kuon]].

* CanonCharacterAllAlong: [[spoiler: His good ending in ''[=UNI2=]'' reveals that Merkava, or rather his original human form, is in fact none other than the Hollow God himself, the man who first gave the Night Blade the secrets of EXS in the first place.]]

* RedEyesTakeWarning: Though he's a good guy.

* UndyingLoyalty: To Linne, mostly out of his pact with Kuon.

* SpannerInTheWorks: Vatista woke up on the Hollow Night where Hilda executes her grand plan to become a Re-birth, becoming this to latter in her arcade story as [[ManipulativeBitch Paradox]] had no way of accounting for Vatista's presence beforehand.

* YouSeeImDying: [[spoiler: In his ''UNI2'' ending, he ends up taking on both Linne's Curse of Reincarnation and Kuon's Curse of Immortality unto himself, causing him immeasurable pain and ultimately leaving him in a broken, pitiful state even though he tries his hardest to bear the sins of his clan. By the time "Linne" finds Seth, he states that the process of him losing himself to the other persona of the Void that now exists within him has already begun, and resigns himself to death at her hands. She, however, implies it's entirely up to him now whether he or the Void can survive.]]

* HidingBehidnYourBangs: To hide his [[GlowingEyesOfDoom Glowing Eye of Doom]] when not in battle.

* {{Leitmotif}}: ''[[https://www.youtube.com/watch?v=HLWVSSP_38U&t=129s Overwhelm Despair]]''. ''Sys:Celes'' gives her a new one by the name of ''Relatively Despair''. She's notably the only character to get an entirely new theme instead of a remix of her original one like everyone else.

* BigBadWannabe: She's the final boss of the first game and it revolves around her plans to become a Rebirth, but is completely unaware that she's merely being used by Kuon.
