Introduced in EXE: Late
Kei "Chaos" Asuma
Voiced by: Yoshitsugu Matsuoka
- He schemes. Staring down his opponents from behind his glasses.
He keeps a beast within, and a book filled with nothing but chaos.
He awaits the chance to unleash his power. The desire to find his beloved friend,
and a comrade who tries to stop him. But which he was going to pick was obvious...
the beast shows its fangs, crushing anything it finds in its path.
- Height: 174 cm (5'8½")
- Weight: 57kg (125 lbs)
- Blood type: A
- Date of Birth: December 5th
- Weapons: Codex of Disorder: Chaos Code
- EXS ability: Umbral
- Known alias: Bloody Chaos
His EXS ability is the EXS of Illusionnote : Umbral, which, as the name implies, gives him control over an illusory creature. Umbral allows Chaos to project and manifest the creature, where its form is based on a particular catalyst that is specifically limited to books, most likely stemming from Chaos' affinity to them. Chaos was unable to fully utilize this ability in combat without a particular catalyst, one which he later steals from Licht Kreis. The particular catalyst happened to be a book called the Codex of Disorder: Chaos Code (No not that one.) which allows him to summon a Void called Azhi Dahaka. The book's mysterious inscriptions became legible for Chaos to read and freely command Azhi to his whims. He is the game's resident puppet-fighter but plays differently compared to other puppet fighters with all of Chaos' specials being related to Azhi's own moveset. His Force Function Sneak Around has him performing a side-roll through his opponents and reposition himself to get out of harm's way or sandwich his opponents between himself and Ahzi. It is one of the few moves he can use outside Azhi aside from his Reflect ability.
His Chronicle Mode story is A Sage Cometh in the Night, where it details his transformation into an In-Birth after wandering into the Hollow Night, his endeavor to seek out a suitable catalyst for his ability, and him joining Amnesia as their tactician.
- Adjusting Your Glasses: How could he not? He primarily does this in his round-win victory animation while he does this in his recovery frames for certain attacks.
- Animal Battle Aura: Subverted. While his docile looks and snobby personality might help in masking his combat prowess, a number of people are able sense something akin to "hidden fangs and claws" just waiting to be unleashed around him.
- Attack Reflector: His Code Reflect command normal works like one, where it'll grow larger for each projectile it absorbs.
- Badass Bookworm: Even though Azhi does most of the fighting for him. He states that he prioritizes intelligence over strength while fighting. On the other side, he's a scholar who loves books and seeks to learn anything that he finds interesting. Despite all of that, he is still able to kick some ass without the need of Azhi.
- The Beastmaster: He summons a reptilian creature named Azhi Dahaka to fight alongside him.
- Breath Weapon: One of Azhi Dahaka's moves (and thus is one of Chaos' special moves) and Chaos' only projectile attack next to his Code Reflect command normal.
- Catchphrase: Not so much a phrase but a favorite word, with Chaos' favorite being "intelligence".
- Constantly Curious: As a scholar, his curiosity and inquiring mind led to his current position as Amnesia's strategist. His curiosity is also what led him to become an In-Birth.
- Cool Pet: While Azhi is definitely something frightening to behold, it almost resembles a dog during Chaos' win pose where Chaos pets it and it wags its tail. Azhi also might count as an Empathy Pet as it represent's Chaos' own inner violent nature.
- Covert Pervert: He discovers that the being he can summon with his EXS, Azhi Dahaka, assumes different forms based on which book he uses to summon it. The thought of using a female idol's gravure photo collection... hasn't crossed his mind.
- Delinquent: His backstory says he used to be one, being a bit of a brute-force fighter before relying more on intellect.
- Difficult, but Awesome: A very notable example. Chaos lacks notable defensive tools such as reversals and even quick-to-use anti-air attacks other than solid pokes, along with attacks that are easily punished and over-reliance on Azhi Dahaka. However, should he be mastered, Chaos along with Azhi can easily pummel his opponent from around anywhere at anytime with solid space control, as Chaos is the only Puppet Fighter who can easily apply the sandwich combo-type of offense.
- Evil Genius: While Amnesia is not particularly evil, Chaos acts as the brains of the group as Hilda is too busy partying to ever plan things out on her own. He sets up the plans, goes over logistics, thinks about their group's image and reputation, and scouts around to find new recruits.
- Heterosexual Life-Partners: With Gordeau, where the latter apparently freeloads in Chaos' house when not working.
- Hipster: Considers himself as such.
- I Know Karate: A lot of his physical attacks involve pretty precise chops.
- In-Series Nickname: His title as "Bloody Chaos" might actually be just a joke among his Amnesia peers. He doesn't like being called that by any means and Gordeau and Hilda tease him frequently by using it.
- Insufferable Genius: Chaos takes great pride in the pursuit of knowledge and he's rather blunt about how he thinks of others for challenging him thoughtlessly.
- Jerkass: He has a particularly nasty habit of putting people he considers stupid below him.
- Jerk with a Heart of Gold: He's an well-meaning and polite person but gets particularly demeaning against people who try and pick a fight with him. He treats his friends, minus Hilda, very well and his amicability is most noticeable during Chronicle Mode where he is the most outgoing member of Amnesia as he scouted out for other in-births to join their cause. He also frequently visited Gordeau to console him after Roger's death and was on friendly terms with Enkidu. He is also amicable towards Seth and Orie in the brief times they interacted.
- Light 'em Up: Has a ton of light-based moves in a majority of his attacks, even if in minor traces.
- Leitmotif: "Erudite Eyes" and "Cross Thought" in matches against Gordeau.
- Mysterious Employer: Chronicle Mode reveals that he is Seth's employer and gives him the Eliminators in exchange for his cooperation, though it was hinted Kuon was the one who gave Chaos both his task and the daggers without his knowledge.
- Number Two: Is this to Hilda. Chaos does all the actual work in planning out operations and sometimes even recruitment while Hilda mostly parties away, making him do all the work she as the boss should be doing. He is constantly at odds with her simplistic tactics and decisions. They do seem pretty friendly over all though.
- Puppet Fighter: He can summon his creature and use it as his main tool to help him in fighting. In some ways it's the only tool he has, since all of his special moves involve it. But compared to Orie, he's the only character who can apply any and notably potent sandwich combos.
- Recruitment by Rescue: Subverted. His victory-screen dialogue has him suggest the person he just beat up to come speak with him later if they were interested in joining Amnesia. Chaos himself was recruited by Gordeau after the former was able to manifest Azhi for the first time and escape from Orie.
- Reluctant Warrior: Chaos tries to avoid conflict since he apparently doesn't like fighting anymore but tends to be pulled into the action to simply prove that brain trumps brawn. With his primary role as that of the strategist, he's much more comfortable sending others to fight when necessary and downplays his own skills to try and avoid being sent out himself.
- Reverse Mole: Averted. While Chaos is intent on achieving Amnesia's goals of bringing authorities like Licht Kreis down, he's currently more focused on helping Gordeau track down Wagner than have faith in Hilda's plans to become a Re-Birth.
- The Rival: Apparently, to Gordeau. It's to the point that they have the first rivalry-specific music in the game.
- Smart People Wear Glasses: Bespectacled, and one of the smartest characters not just in Amnesia, but the setting as a whole.
- Spell Book: Holds one of these in battle, used to either cast his own magic or control Azhi Dahaka.
- Spell My Name with an "S": Azhi Dahaka in the English localization is instead spelt as "Aji D'haka".
- This even applies to his name, where Chaos in katakana is written as "Keiasu" instead of the usual ways to write in katakana being "Kaosu", "Keeosu" and "Keiosu". It may instead actually hint at the portions used for his name if written in Western order however....
- Throw the Book at Them: His Code Reflect has him magically sending his book forward with a light rune accompanying it.
- Tranquil Fury: He's absolutely livid when he finds Gordeau badly hurt from fighting Hilda and Hilda just decided to leave him there to die in arcade mode.Chaos' thoughts: (If he's not waking up why didn't you take him to a hospital, you dumb cow?)
- Unnecessary Combat Roll: Has one as his Force Function, which not only can dodge attacks, but can easily cross-up his opponent during sandwich combos or get him out of tight spots into a nifty position of a reversal in the hands of a skilled player.
- White Collar Worker: He seems to make a fair bit of money from his unspecified profession, at least enough to confidently say he and Hilda's income can keep Gordeau's bar in business with their patronage alone. Tidbits suggest that he's part of some business firm.
Voiced by: Mayu Iizuka
- She dances. Taking on the pure air from the night sky, she seeks the one who turned
her into an In-birth. The young boy with a long red blade. Her pure and silky white skin,
that is contrasted with her body that has been consumed by the night.
The traces of her innocence are clouded. Is what she is feeling truly the desire for
vengeance? Perhaps the answers will present itself in the story... maybe.
- Height: 159 cm (5'2")
- Weight: 44 kg (97 lbs)
- Blood type: O
- Date of Birth: February 15th
- Weapon: Zephyr
- EXS ability/Known alias: Windmill
A second-year middle school student that heard rumors of the Hollow Night and decided to investigate the claims with her friend, while having a slight misunderstanding of the context of what the Hollow Night actually involved. She accidentally runs into Hyde where she accuses him of being some lecher and ensuing commotion of their meeting caused a Void to bite Nanase. Hyde dispatches the Void and saves Nanase's life and leaves her in the park after she regains consciousness. Since then, Nanase is strangely infuriated by her transformation into an In-Birth and hunts Hyde with a notable passion that quickly earned her a reputation out in the night.
Nanase possesses the EXS of Vengeancenote : Windmill, which grants her power over wind and the ability to summon her blade called Zephyr as well as granting her the small wings on her shoes to help her float. Nanase's gameplay is reflected with her emphasis on staying airborne, manipulating her fireball trajectories, and extensive air combos. Her Force Function Liberté of the Gentle Breeze gives her a secondary jump mechanic that further increases her air-time and allows for her to set-up ambiguous jump-in angles and attacks.
Her Chronicle Mode episode is called Dreams of the Night where she and her classmate Tomomi head out into the city's park at night to confirm the rumors regarding the Hollow Night are true, where Nanase mostly thought to herself that the rumors involved something of harassment and general misconduct instead of anything related to super-powers. She encounters Hilda before she runs off and encounters Hyde, who she tries to antagonize before she is bitten by a Void in the confusion.
- Action Girl: Fueled by some twisted sense of vengeance from gaining super-powers, she heads out into the night to hunt Hyde.
- Belligerent Sexual Tension: It's implied by her arcade ending, character description, and some lines in Chronicle Mode that one of the reasons she's so fixated on Hyde and thinks he was coming on to her like a pervert when they first met is because she finds him attractive. Unfortunately, her youthful immaturity that comes with being a middle schooler and constant misunderstandings lead to her not being able to express these feelings properly.
- BFS: Her sword, Zephyr. She is apparently able to swing it so easily because of the ever-constant stream of wind that follows her.
- Blessed with Suck: What she thinks being an In-Birth is. Compare this to Phonon who actually WANTED powers and is absolutely ecstatic that she has them.
- Blow You Away: Her EXS ability pertains to controlling the wind, which she integrates into the majority of her moveset.
- Childhood Friends: With Phonon.
- Confusion Fu: In essence, this is what her playstyle boils down to. Nanase has some of the most aerial movement options in the game so the best way to play her is to move in ridiculously unpredictable paths while airborne. While unpredictable movement is best with any character, Nanase's tools allow her to do almost anything once she jumps, making reads extremely hard against her. On the ground, she's significantly more limited but she has a fast sliding dash just in case she decides not to jump for another surprise for the opponent.
- Dangerously Short Skirt
- Deconstructed Character Archetype: Nanase is a subtle Take That! to violent Tsundere girls that jump to conclusions that have overrun anime and games for years. Instead of being endearing or having heartwarming moments with her dere side, she not only causes trouble for the actual protagonists, no one can understand her thought processes either and her few friends have to have a lot of patience to tolerate her. It's still Played for Laughs, but her multitude of negative traits land her solidly in Joke Character territory.
- Deus Sex Machina: How she initially thinks people become In-Births due to her ridiculously low intelligence and misunderstanding everything she hears. This is because Nanase stumbled upon a pornography site while looking up the Hollow Night and believed that people become In-births through sex. As a result, she thinks the void biting her was Hyde using brainwashing powers to molest her for some reason when he obviously did nothing of the sort in fact it should have been fairly obvious to most people he was desperately trying to protect her even with Nanase being completely uncooperative with him, nor can he even mind control people to begin with. It finally takes Linne, Orie, and Vatista spelling it out to her that her situation has nothing to do with him for her to drop it, and at most she becomes a very Tsun-sided Tsundere towards him.
- Dramatic Wind: Even when she's standing idle, wind blows on her Girlish Pigtails.
- Early-Bird Cameo: Originally meant to be in arcade version of original version of Under Night In-Birth. Until she went Ascended Extra to be Promoted to Playable in console version of Exe: Late update.
- Gratuitous French: All of her moves, including her Force Function are written in a combination of both French and Japanese.
- Final Boss: Of Phonon's arcade mode.
- The Friend Nobody Likes: Most of the other characters don't hate her and she is definitely not on the bad guys' side, but tolerating her antics gets tiring for even the likes of Vatista and Orie. Nanase's only real friend is Tomomi with Phonon being too lost in her made up persona to be anything more than a complete Jerkass to her, even if Nanase still considers her a friend.
- Foil: To Phonon. While Nanase never wanted powers, Phonon actively seeks them out. Their transformations into In-Births are very different as well. Phonon nearly gets herself killed in a traumatic experience due to seeking out a void on her own that almost eats her. This leaves her begging for her life and at that moment wishes for a normal life as long as she doesn't die before she gets her powers and gets drunk on them, but in Nanase's case she wasn't in any real danger due to Hyde being there and because she passed out during the process her transformation was much less mentally scarring, and only accepts her power after she realizes she's stuck with it and it isn't Hyde's fault. Nanase also is mostly well-intentioned Idiot Hero with an emphasis on "idiot" who values her friends, while Phonon is smart (but nowhere near as smart as she thinks she is) and is a jerk to everyone even if they care about her. Nanase is also completely disgusted by Hilda's behavior, but Phonon wants to become just like her.
- Hypocrite: Chronicle mode revealed that only reason that she mistakenly thinks Hyde is a pervert and a molester is that she herself tends to jump to extremely perverted conclusions. Nanase's imagination tends to gravitate towards the more lewd explanations when she doesn't understand something, and with her Hilda-level intelligence, Nanase misunderstands just about everything. Funnily enough, chronicle mode also revealed that Hyde's thought process has a few of the exact same problems. But he's slightly smarter and MUCH nicer in comparison to Nanase and as a result, has more self-control. In fact, it's heavily implied that Nanase actually has a crush on Hyde, which makes her behavior towards him even more erratic around him than it is normally.
- Idiot Hero: Not only does she somehow mistake Hyde for being a pervert when there's absolutely no way he did anything wrong to her (he actually saved her life), she presses her senior, Phonon's Berserk Button multiple times by calling her by her real name. Despite being fairly difficult to interact with and causing a lot of trouble, she's on the good guy's side and is probably on decent enough terms with Hyde after her arcade mode.
- In a Single Bound: Her Force Function, Soyokaze no Riberete (Liberté/Liberty of the Gentle Breeze), which causes her to fly high into the air for some aerial gimmicks. Can also be done in midair like a Double Jump, but not from the grounded version of the Force Function.
- Insane Troll Logic: The only reasonable explanation as to why she thinks Hyde "violated" her. Chronicle mode finally showed her thought process, and it makes even less sense now.
- Jerk with a Heart of Gold: A complete Brainless Beauty that jumps to wild conclusions and nearly gets herself killed by being uncooperative, and then blames her savior when she becomes an In-Birth. Her entire arcade scenario involves her nearly ruining Hyde's relationship with several other girls with her false accusations born from said wild conclusions. That said, she cares about Phonon enough to not break Phonon's Chuunibyou delusions to keep her happy even after Phonon beat her up quite badly. Nanase also tells herself that she never wants to grow up to be as cruel and heartless as Hilda, and she does warm up to Hyde a bit in her ending. To put it simply, Nanase is just an average middle schooler who lacks the intelligence or maturity to not be a jerk to most of the cast despite being a decent human being.
- Joke Character: Storywise only. Nanase's arcade mode (and some of her chronicle mode) is basically one giant joke at Hyde's expense. Hyde is not amused.
- Launcher Move: Her 3C, much like Hyde's. Only she handstand-kicks her opponent upward. Also has a ton of these with her other moves. She carries a unique trait where she's the only character who can jump-cancel off blocked launchers.
- Leitmotif: "Gallant Girl ~Blowing Wind that Flows from the Sky~"
- Nice Shoes: Her small boots even have little wings on them.
- One-Handed Zweihänder: Occasionally wields her sword like so for some moves, but other than that, she normally wields it two-handed.
- One-Word Vocabulary: At least when it comes to the English Language. Nanase found the word Windmill exceptionally cute for some reason and wouldn't you know it, that's what becomes she's known as out in the Night, as well as being the name of her ability.
- Power Palms: Her Infinite Worth, Atomosufia no Tenkuu (Atmosphère/Atmosphere/Ambiance of the Aether), involves her uppercut-slashing Shoryuken-style her opponent into the sky, then generating a wind-ball on her free palm to grind into them not unlike Naruto's Rasengan.
- Rant-Inducing Slight: Her story opening has her ranting about how Hyde "defiled" her. Turns out in her ending that she just turned into an In-Birth after he saved her from a Void, and she chases Hyde so that he takes responsibility and returns her to normal. In her ending, Linne, Vatista, and Orie all tell her that chasing Hyde will never change the fact that she is an In-Birth and nor can he change her back. She appears to take it to heart. For now.
- Chronicle mode explains that the reason why she thinks Hyde defiled her is that she came to the ridiculous conclusion that In-Births gain their powers through Deus Sex Machina, and that Hyde was responsible for turning her into one. She is eventually convinced that this is NOT the case.
- Sempai/Kohai: Kohai to Phonon
- Ship Tease: She becomes a Tsundere towards Hyde in her arcade ending, showing him a minuscule bit of her dere side.
- Shoryuken: Her midair 8C, Tamani wa Ra Aruto (La Halte/The Stop/The Halt Once in a While), Anju no Sasoi (Ange's/Angel's Invitation) and Kaze ni Mau Purumaaju (Plumage/Feathers Dancing in the Wind).
- Ungrateful Bitch: How does she repay Hyde for saving her from a Void? By accusing him of being a pervert and chasing him all over the city just to kick his ass.
- Tsundere: Acts a lot like one. Nanase is Deredere by default, with the Tsuntsun rearing its ugly head when Hyde is involved somehow. She starts to show a tiny bit of Deredere to Hyde in her ending.
- We Used to Be Friends: Nanase is a bit frustrated in Phonon's arcade ending about Phonon attacking her and trying to forget their time together. She still decides to play along to make Phonon happy anyway.
- Wind Is Green: She dresses primarily in green, and the tornadoes she summons for her attacks are also green.

- They nest. The web will lure and consume any prey that goes near.
He, for her, and her for herself, they fight.
Her feelings point to one direction, to a friend defeated.
She sips on blood, and mud alike, chasing a shadow.
His eight legs will crawl through the night once more, carrying with him her feelings.
- Height: 116 cm (5'5")
- Weight: 50 kg (110 lbs)
- Blood type: A
- Date of Birth: December 24th
- Weapon: Eight Legs of Shredding: The Predators
- EXS ability: Chelicerata
- Known alias: The Non-Volitional Predator
His EXS ability is the EXS of Dark Spikesnote : Chelicerata, which allows him to spin webs like that of a spider's and prey upon the EXS of others. His weapon is the Eight Legs of Shredding: The Predators, which takes the shape of eight large dagger-like blades similar to a spider's legs that mysteriously hover around Byakuya's body. They are able to be freely manipulated into spinning, growing in length, cutting, and essentially act as extra limbs for him to use. In terms of gameplay, Byakuya is able to space out his attacks with his long-range and utilize his grd-block stealing webs to keep his opponents trapped on the screen. His Force Function Can I Leave This Gadget Over Here? (Just kidding) adds to his repertoire of tools to open his opponent's defenses by feigning a web set-up and striking with his extended Predator blades.
His Chronicle Mode Story is I Love My Sister which covers Byakuya's close relationship with his sister and how he eventually succumbs to some mysterious creature before he awakens and finds himself reborn as an In-Birth.
- Ambiguous Disorder: Probably the best answer as to why he's completely obsessed with his sister. Although Chronicle Mode does reveal that Tsukuyomi is the only family he's got left.
- Animal Motifs: The spider. He traps his opponent in webs for several of his moves and his Infinite Worth EXS Endless Nightmare shows the eight floating daggers he wields attached to his back, which only makes him look like one.
- Arch-Enemy: Is most likely going to become this to Zohar. Considering that she was the one who nearly killed Strix and put her into a Zero Vessel state.
- Ax-Crazy: To say that this kid is unhinged is one hell of an understatement.
- Berserk Button: Don't ever, ever threaten or harm his sister.
- Born Unlucky: Judging by what he says about himself in his Chronicle Mode story and his sister's death, Byakuya's luck is almost nonexistent. Evidence suggest that his body is rather frail to begin with.
- BrotherSister Incest: His love for his late sister is a bit too on the side of obsessive, to the point where he had various pictures of her, risque or otherwise, pinned around his room. He tries to deny having any incestual thoughts, but whether or not he's being honest is up in the air.
- Brother-Sister Team: With Tsukuyomi. Except his ending reveals that they were only pretending to be one. This is actually played straight once he learns her true intentions and decides to keep helping her.
- Confusion Fu: Byakuya is able to fake planting a web in both his "Shall I Leave This Gadget Over Here?" and "Almost Ready To Eat!" specials. The former being his Force Function. He also has a feint "command grab" like maneuver and his Infinite Worth is also a unique that it counts as a grab and cannot be blocked normally.
- Difficult, but Awesome: That being said, Byakuya has a ton of ways to setup traps in both offense and wakeup to pretty much limit his foes' options. However, the biggest weakness he has tends to be his laggy tools and the gaps that in his movements that can easily be exploited by knowledgeable opponents; adding to this is the fact that he has no normal attacks that come out faster than 5 frames, giving him some weak mashing-poke options at best.
- Creepy Child: He's rather short, and his mannerisms can be absolutely unsettling.
- Dumb Muscle: Downplayed. While he's not muscular, he is certainly powerful and treated as such. Likewise, while he's not dumb he doesn't feel easy with things like details or small talk.
- Driven to Suicide: After psychotically lashing out at people on the street and breaking down crying, Byakuya completely goes off the deep end and starts talking about being with his sister "forever". The implications speak for themselves, though it takes surviving a Void bite to make him snap out of it and continue living on.
- Dull Eyes of Unhappiness: He doesn't really emote much.
- Hair-Trigger Temper: He can go from calm and mild-mannered to angrily yelling like a lunatic in a moment's notice.
- Humanoid Abomination: Certain characters such as Chaos, who is notable for his observational skills, and Merkava, an intelligent monster, particularly ask what the hell is Byakuya's deal physically. Apparently, Merkava senses that Byakuya's stomach is similar to his own, suggesting that Byakuya might have something "in" him. Chronicle Mode confirms this after showing something slide down the poor kid's throat.
- I'm a Humanitarian: As noted above, he eats his victims. Sometimes alive.
- It's All My Fault: After Tsukuyomi dies, Byakuya develops an intense guilt complex, blaming himself for her death. It only ends up causing him to spiral further into madness.
- Leitmotif: "Beat Eat Nest".
- Names to Run Away from Really Fast: He is referred to as "Predator".
- Not Blood Siblings: As revealed in his ending. Chronicle Mode reveals that his real sister was killed months ago.
- O.O.C. Is Serious Business: In an insanity-induced trance, Byakuya goes out to look for his dead sister. The noise of the bustling city and the bright lights end up getting to him and he completely loses it.
- Ordinary High-School Student: He looks like one and Hyde even supposes he's coming from another middle school nearby when they meet in his Arcade mode.
- Rant-Inducing Slight: Byakuya is already barely holding it together after his sister's death, but the bustling noise of the city streets causes him to completely and utterly flip his shit.Byakuya: "It's all NOISE! Just NOISE! TRASH! You guys are in my way! Hurry up and go away!! Go away!! DON'T GET IN THE WAY OF ME AND MY SISTER!!
- Shout-Out: Byakuya bears a resemblance to Yu Narukami. Meanwhile, his use of floating blades somewhat resembles that of the Murakumo units.
- Slasher Smile: His story dialogue sprites include an fairly creepy one.
- Trap Master: His playstyle allows him to place down webs that allow him to trap opponents and can even combo off of placing down a web. Also one of the privileged few who can combo off their grabs.
- Tragic Monster: Chronicle Mode reveals that he was once a pretty normal kid, rather unhealthy obsession with his sister aside. Until one day, he winds up finding his sister's corpse in the street after getting into a fatal car accident, causing him to go off the deep end. All of this turns into a downward spiral, resulting in his transformation into an In-Birth.
- Trauma Conga Line: To start, Byakuya loses his sister in a fatal car accident. This ends up driving him into a suicidal depression. After that, he ends up being attacked and nearly killed by a strange creature, leaving him with strange claws growing out of his back and driving him even more insane. By the time he meets Strix, he's apparently fallen so far into madness that he went on a killing spree while looking for his sister, who he knows died months ago by that point.
- Troll: He takes quite a bit of pleasure of winding people up to goad them into fighting him.
- Undying Loyalty: To his sister, Tsukuyomi. During his story, he's mostly her attack dog. In his ending, it's revealed to be charade they both put up. It even looked like he was going to betray and eat her at the end, but after learning what her motivations are, he decides to keep helping her. He also becomes completely convinced that Strix is his sister reincarnated, despite Strix being born around the same time as her.

- She wishes. For the paranormal ability, from the deepest spirit of hers. Along with
the white follower. False shell at present. The wish will be fulfilled when the time comes
right here. The sword speaks. The path to the bright future. She fails. The sword exposes. The
path from the cloudy past. She overrides.
- Height: 157 cm (5'2")
- Weight: 45 kg (99 lbs)
- Blood type: AB
- Date of Birth: August 5th
- Weapon: Muniel
- EXS ability: Baroque Noise
- Known alias: Chemeti
Phonon possesses the EXS of Resonancenote : Baroque Noise, which allows her to generate extremely powerful, sound-based attacks. This is paired with her weapon of choice, Muniel, a snake-like Void gifted to her by the EFG members during her induction. Muniel transforms into a whip and the lashing is paired with sound-projections that she is able to send out against her enemies. Phonon's sound-based abilities are exemplified through her projectiles multi-hitting properties as well as through her disjointed reversals and ground projectiles. Her Force Function Impulsive Frustration acts as Phonon's anti-air move where she swings her whip in a large circle above her head before she slams it back down.
Phonon's Chronicle Mode episode is A False Identity, A True Self that covers her attempts at becoming an In-Birth, succeeding at running into a Void out at night, and making it out the encounter alive. Days later, Phonon is scouted out by members of the EFG who bring her to their headquarters and ask for her temporary cooperation to which she accepts after being bribed with a weapon they offer her in return.
- Action Girl: While other girls are out to fulfill a duty, pursue their noble goals, or strive for ultimate power, Phonon is mostly out there fighting because she wants to simply use her powers and revel in how cool she is.
- Ambiguous Disorder: Implied to be the source of her Chuunibyou personality and disturbingly strong desire to throw away her identity.
- Animal Motifs: Considering that her weapon is a snake.
- Boredom Montage: Wasn't satisfied of her peaceful life and seeks for her "true self" instead.
- Berserk Button: She doesn't like being called by her actual name, Yoshiko, and insists that you call her Phonon. Make that mistake repeatedly, and she will whip you real good, as Nanase learns the hard way.
- Childhood Friends: With Nanase, who she used to be close with during their younger days. Phonon was an avid storywriter and a fan of magical girls and Nanase admired her for her imagination. These days they're still good friends, but their personalities tend to clash a lot more.
- Chuunibyou: Phonon, or rather, Yoshiko's, defining character trait. She jumps at the chance to make her magical girl fantasies real albeit with a bit more of an edgelord variety fitting of a middle schooler. This leads her to make some incredibly stupid decisions and even makes her attack Nanase when Nanase is only trying to be nice to her.
- Combat Stilettos: Wears a nice pair of black heels which also serve to add to her Sadist theme.
- Cool Pet: Meuniel, her pet-snake doubles as her whip but has a time-limit depending on Phonon's concentration. Her win-screen quotes might have the cute snake returning to its non-weaponized form and affectionately slithering around its master. It's also a fragment of a Void that more or less been pacified through being awakened by its host's EXS.
- Cute, but Cacophonic: Her voice can be rather annoying at times.
- Deconstructed Character Archetype: Much like Nanase deconstructs the typical anime Tsundere, Phonon or rather Yoshiko deconstructs the cute young Chuunibyou girl character type. It quickly becomes clear that unlike typical examples of this in recent anime where the girl is kind and harmless but needs friends to pull them back to reality and usually will do so after a dramatic experience brought on by their constant seperation from reality, Yoshiko's delusions are strong enough to make her a physically violent Jerkass who is so in to her made up identity and worried about being embarrassed that she is incapable of having friends, with a particularly bad violent outburst at Nanase. When a chance to actually gain powers shows up, she becomes Lethally Stupid in her pursuit of them. Her Suicidal Overconfidence problems continue after gaining her powers, putting herself in constant danger during the Hollow Night. She also has constant fears of embarrassment from being a normal girl that is so overwhelming that she only temporarily discards them during a near-death experience.
- Ignored Epiphany: Phonon learns nothing from the absolutely terrifying experience of nearly being eaten by a void and feeling like she was dying from her In-Birth transformation sickness. She desperately wishes that she wants her normal life back during her near-death experience, but goes back to being obsessed with EXS powers immediately after.
- Headphones Equal Isolation: Subverted as it mostly protects her own ears from being damaged by her sound-based attacks.
- Insufferable Genius: She's noted to be quite fond of wisecracking, and looks down on others.
- Jerkass: Yoshiko's delusions cause her to act extremely selfish and cruel to those around her. Being a moody middle school aged girl, anything she finds embarrassing (and fitting of a middle schooler she's embarrassed about almost every aspect of her life) will set her off, causing her to become rude and even violent. Her opinion of herself is also far too high when in reality she isn't too wise and is just as much of a plaything for the supernatural forces of the Hollow Night as everyone else, leading her to treat everyone else like crap.
- Leitmotif: "Sounds Of Night Wind♪"
- Long-Range Fighter: She's got one hell of a range with her whip.
- Not So Different: From Hilda, something that horrifies Gordeau. Not only does also she have an overblown ego, thinking that she's far stronger and smarter than she actually is, she also shares Hilda's sadism and domineering personality. It's mostly Played for Laughs. She also shares a similar playstyle to Hilda's being a long ranged zoner that fills the screen with hitboxes while keeping away from her opponent. She also longs for powers that no one is meant to have out of overconfidence that she can handle it. Her experience becoming an In-Birth is eerily similar to Hilda's seeking to become a Re-Birth and may be subtle Foreshadowing of Kuon's warning to Hilda. Up until the point where her life is in danger, Phonon shows no fear and seeks out something that can kill her or worse, but it all comes crumbling down once she encounters the void. After a long and horrifying chase Phonon internally starts begging for her life as her soul's existence starts to become unstable from the void's bite. Once the initial danger is over, she reverts back to her Suicidal Overconfidence, jumping into the Hollow Night with no concern for her own safety.
- O.O.C. Is Serious Business: As Phonon's main defining character trait is I Just Want to Be Special, her horror and frantic wishing for a normal life in her near-death experience shows how in over her head she really is. She immediately regrets ever wanting powers as long as she doesn't die. Unfortunately, the lessons from this experience don't stick.
- Ridiculously Cute Critter: Meuniel, a small, white snake that sounds like a cat and communicates via cow noises. It manages to possibly outdo Kuu in the cute Void department.Meuniel: Muu...
- Sadist: Her playstyle certainly looks the part, with some dominatrix elements incorporated into it. This image of a sadist-dominatrix is something she tries to pose as during the Hollow Night and her Arcade Mode has her looking to meet Hilda to learn how to best live out this image despite the protests of Gordeau.
- Sempai/Kohai: Sempai to Nanase.
- Shout-Out: Of Whip in term of playstyle and personality.
- The Stoic: She's normally rather cool and collected out of battle, but...
- Not So Stoic: Her cool facade comes down when her Berserk Button is pressed or in battle. Actually, it comes down a lot more frequently than one might think. While she is definitely skilled, she's still very new to the scene. She tends to overthink things and play herself up more often than not. She also panics when the void she searched for nearly kills her, wishing she had never done it and that she only wants to be normal as long as she survives.
- Whip It Good: Her weapon is a whip, which transforms from her pet snake.
- You Gotta Have Blue Hair: She has green hair, it originally used to be a more black/brown color.

- Height: 142cm (4'8')
- Weight: 35 kg (75 lbs)
- Blood type: B
- Date of Birth: March 2nd
- Weapon: Pachebel Cannons
- EXS ability: Diesel
- Known alias(es): Fauster, Executor no. 10
Mika's ability is the EXS of Drivenote : Diesel, which most likely enhances her already staggering strength. She utilizes two over-sized gauntlets called the Pachelbel Cannons that not only complement her power but also act as propulsion to further add more force to her attacks or rocket her around in the air. All of Mika's specials help her close the gap between her opponents which lends to her strong pressure game. Her Force Function is Mika-Chan Crash that allows her to bring her enemies down with her in a downward, rocket-propelled punch.
Her Chronicle Mode Story is called Meeting with a Friend which details Mika's escape from Licht Kreis' headquarters, where she defies her orders to stay behind and finish her assessment, to help Orie and her friends in Japan. Mika survives her superior's rather brutal challenge of being forced to abandon plane mid-transit, living off the land in a remote island, and eventually crossing the sea on a makeshift raft before she finally arrives in Japan.
- Action Girl: While not the sharpest tool in the shed, she's got the strength to make up for it. She definitely means well as her duties as an Executor has her out fighting for a just cause.
- Amazon Brigade: The Vanguard of Orie's 4-person Executor Squad.
- Ascended Extra: Mika is only mentioned and seen in Orie's Arcade ending. Come Late[st], she becomes a fully playable character.
- Ass Kicks You: Her Hip Attack super and 3B both involve her leaping into the opponent rear end first.
- Bare Your Midriff: Thanks to her rather revealing combat outfit.
- Badass Adorable: Equally capable of taking names and captivating hearts.
- Beware the Silly Ones: Don't be fooled by her idiocy and Cloudcuckoolander tendencies. Mika is rumored to have enough strength to rival the likes of Wagner.
- Butt-Monkey: If the piles of humiliation she suffers in her own Chronicle mode story aren't enough, she hurts herself even after winning a match.
- Church Militant: As per her duty as an Executor of Licht Kreis.
- Cloudcuckoolander: She's certainly out there, if her suddenly bursting into rap during her argument with Silvaria is anything to go by.
- Cute Bruiser: She's an adorable, if unintelligent, young girl and she hits like a freight train.
- Determinator: If her introduction is to be believed, she went through a lot just so she could help Orie.
- Turns it it's all absolutely true.
- Dumb Blonde: She's not a very bright individual and is frequently teased for her lacking intelligence. Her fellow teammate Kaguya is notable for messing around with her the most.
- Dumb Muscle: She can rival the likes of Hilda in terms of stupidity.
- Engrish: Specials aside, she has a few instances of this. Most notably in her dashing C and Force Function.
- Genki Girl: Mika is very hyperactive. It's rather noticeable in her walking animation, where she skips instead.
- Girlish Pigtails: Rather short ones too.
- Glass Cannon: Despite how much damage she can put out, she takes hits about as well you'd expect a teenage girl wearing next to no armor to.
- Idiot Hero: She's an Executor of Licht Kreis, obviously meaning that she fights on the side of good. She's also hilariously stupid.
- Joke Character: Her Chronicle mode "story" more or less amounts to one long Humiliation Conga for her as she tries to get to Japan to meet up with Orie, all depicted in terrible crayon drawings. She used to be considered this in gameplay, but players getting better with her has made Mika be taken more seriously in the competitive environment.
- Leitmotif: "Forceful Step" and to an extent, Canon in D.
- Megaton Punch: Her modus operandi.
- Muscles Are Meaningless: She's somehow able to heft around and slug things with those massive gauntlets of hers with little issue.
- Pint-Sized Powerhouse: She's a measly 2 centimeters taller than Vatista, the shortest member of the cast, but shares Waldstein's role as the local grappler.
- Plucky Comic Relief: When she was introduced, she beat out Nanase as the number 1 joke character of the series. Her Chronicle Mode episode seems like something ripped straight out of a gag-manga.
- Power Fist: Her weapons of choice, called the Pachelbel Cannons.
- Shout-Out: Her boisterous attitude, reliance on a pair of oversized steel gauntlets, and partnership with a more traditionally ladylike enforcer may remind people of Vi. Even their poses in both their official artwork and idle stances are the same.
- Standard Snippet: Her leitmotif incorporates a small snippet of Pachelbel's Canon in D, the same track that her fists get their name from.
- Stripperific: Her sleeveless, midriff-revealing top and shorts aren't exactly modest.
- Stylistic Suck: Most of the background images of her Chronicle Mode story consist of her rather poor crayon drawings.
- Tomboy and Girly Girl: The Tomboy to Orie's Girly Girl.
- Underestimating Badassery: She gets this a lot due to her childish appearance and her low rank in the Licht Kreis. No one, save for Waldstein, takes her seriously.
- Unskilled, but Strong: Mika's fighting style mostly consists of flying into her opponent via her Pachelbel Cannons and wildly attacking with rapid-fire punches, fist slams, butt bounces and tripping herself up when up close.
- Verbal Tic: Ends most of her speech with "yuu".
- Who Wears Short Shorts?: Mika wears fairly puffy short shorts that look more like bloomers than anything..

- Height: 214 cm (7'¼")
- Weight: 94 kg (207 lbs)
- Blood type: A
- Date of Birth: August 24th
- Weapon: None
- EXS ability: Maelstrom
- Known alias(es): The Sin-Slaying Beast, The Maneater
Enkidu possesses the EXS of Calamitynote : Maelstrom, which only slightly buffs the power of his strikes. The extent of his powers in his normal state only allows him to fire energy blasts from the palms of his hands, while his IWEXS suggests that he has more power than he lets on when his wrist-chains come off. He has no weapon to speak of, only relying on his mastery of the martial arts he has dedicated himself to over many years. Enkidu's unique gameplay mechanic Havoc adds extra frames of hitstun as well as damage to opponents he lands a counter-hit on, allowing for combos routes not normally possible without Havoc's effects. His Force Function Revolving Heaven Whirl acts as his anti-air move that has him perform a rising, spinning kick to catch airborne opponents.
Enkidu's Chronicle Mode story is Festival Flames which details Enkidu attending the victory over Bankikai afterparty thrown by Hilda at her building where he attends a meeting with Chaos and Hilda, where he gets slightly more acquainted with the both of them.
- Ambiguously Brown: Has a darker complexion than most characters, but is never elaborated on.
- Ascended Extra: His only appearance up until he was made playable was as a brief cameo in Hilda's ending.
- Barefisted Monk: Enkidu doesn't use any weapons, and his EXS powers are quite weak, but still fights completely bare-handed.
- The Big Guy: For Amnesia. He leaves at the end of his Arcade story however.
- Blood Knight: To the extent that he allowed himself to be bitten by a Void because he ran out of human opponents to fight. He's quite thankful that the Hollow Night lets him fight with all he's got.
- Blue and Orange Morality: If someone insists on fighting Enkidu and he is not pleased with his opponent's strength, he considers them to be a weakling wasting his time and he will kill them. Orie learns this the hard way in his arcade route, despite his "The Reason You Suck" Speech to her and multiple attempts to make her leave. However, if he thinks someone gave him a good fight, there is a chance he will let them live in hopes of bringing him more good fights in the future.
- Chained by Fashion: Has two large, broken cuffs on his wrists with chains hanging from them.
- Challenge Seeker: After running out of human opponents to fight, Enkidu voluntarily became an In-Birth so he may find supernatural ones instead.
- Charles Atlas Superpower: His immense strength is from years of martial arts training.
- Cool Old Guy: While he seems like a stoic, quiet figure, he's actually rather easygoing and is said to often tease Gordeau every now and then. He is also rather polite with how he thanks his opponents during his match-winning dialogue for giving him an enjoyable challenge. He is also empathetic to Gordeau as he had also lost someone close to him in an unforeseen accident.
- Counter Attack: His Stance of Circulating Control will nullify and/or counter anything that isn't a grab. But it's reliability is rather poor.
- Damage Over Time: Havoc's effects work similarly to a poison/burn debuff where it's extra damaged is applied separately.
- Dumb Muscle: Enkidu has no problem admitting that he's not the smartest individual but his thirst for fighting belies his philosophy and insightful view of battle, though he seems less impulsively stupid compared to other examples. He's also well aware that he is genius compared to his former boss, Hilda.
- Empowered Badass Normal: While an In-Birth like the others, Enkidu's powers are significantly weaker than normal due to the small size of the Void bite he received, but he bridges the gap with his years of martial arts training and experience.
- Eyes Always Shut: He is almost never seen with his eyes open, only opening one during his match start animation and opening both during his IWEX.
- Expy: To Kouma Kishima gameplay wise and Geese Howard in terms of design. Character wise, he serves as this series' answer to the likes of Akuma and Azrael, a Blood Knight with a strict sense of honor and wishes to find a Worthy Opponent in battle.
- Foil: To his rival, Waldstein. Both are old men and for the most part fight with their bare hands, but while Waldstein is loud and boisterous, Enkidu is more reserved and diligent. Meanwhile, Enkidu lacks any notable strength, but has the combat experience to make up for it, while Waldstein prefers a more direct and brutal fighting style that takes full advantage of his strength.
- Graceful Loser: Most characters are in shock, disappointed, angered, sad, or even embarrassed when they lose by time-out. Enkidu, however, has the least annoyed expressions during his time-out loss pose as he simply sits down seiza style waiting for the next match to begin.
- Even when he's victorious, he's courteous in thanking his opponents for providing him with a challenge and even humble when he admits that he's still very inexperienced.
- Hurricane Kick: Subverted. Instead of going horizontally, his Force Function has him go upwards in a spiral akin to Rock Howard's Rising Tackle.
- Large Ham: He tends to be rather loud whenever he's fighting.
- Leitmotif: "Extreme Stream"
- Mr. Fanservice: Perpetually shirtless, putting his heavily muscular tone and arm tattoo on full display.
- Names to Run Away from Really Fast: Some of his nicknames include "The Maneater" and "The Sin Slaying Beast".
- No Social Skills: Slightly subverted. While he's not exactly hopeless, he still struggles a bit when it comes to extended civil conversation.
- Not So Above It All: According to Gordeau, the normally stoic and quiet Enkidu can be somewhat of a joker and likes to tease the former every now and then. Similar to Chaos, Enkidu also likes to take jabs at Hilda.
- Only Known by Their Nickname: Subverted. Either due to natural forgetfulness or old-age, Enkidu mostly refers to his colleagues by their nicknames. He refers to Gordeau as Greedy One/One of Greed (Gouyoku no mono), Chaos as Chaotic One/One of Chaos (Konton no mono), and Hilda as Dazzling Darkness (Mabayuki Yami).
- Power Limiter: The shackles on his wrists seem to act like this.
- Power Palms: His Infinite Worth, Rasen Soushouda (Spiral Twin Palm Strike). When used from a distance, however, it functions as a Kamehame Hadoken.
- Power Tattoo: During his IWEXS, Enkidu's entire body-outline becomes a shadowy figure with his eyes, mouth, and his tattooed right arm surging with power.
- Red Baron: He's garnered a reputation as the Maneater (or literally, "Rakshasa").
- Red Oni, Blue Oni: The blue to Waldstein's red.
- Screw This, I'm Outta Here!: At the end of his arcade scenario, he quits Amnesia and leaves to parts unknown, believing to have done his part. He promises to be back for the next Hollow Night to kill them all in one on one combat, despite somewhat liking them.
- Shockwave Stomp: His Trampling Echo special.
- Suddenly Voiced: In his debut in UNIEL, he doesn't speak a word.
- The Quiet One: Only speaks when absolutely necessary. He becomes a lot louder when fighting however.
- The Rival: To Waldstein and Gordeau. While he entered the Hollow Night specifically to fight Gordeau, it's been mentioned that he has a score to settle with Waldstein.
- The Stoic: To the very end.
- Three Strike Combo: Enkidu's normals are unique as his Medium and Heavy buttons can be repeatedly pressed to have him execute a simple three hit chain, six if all three hits from the medium attacks are canceled into the heavy ones. His Three Forbidden Impacts special are also, as their name implies, three powerful strikes. The charged medium and EX version instead goes for a singular, but powerful punch.
- Troll: Teases Gordeau quite alot.
- Walking Shirtless Scene: Wears a robe that only goes down one side of him in cutscenes, exposing most of his bare chest. In battle, he ditches the robe.
- Weak, but Skilled: Not by human standards, but Enkidu is noted to have very faint In-Birth powers. His skill with ancient martial arts bridges the gap in power quite nicely. This was apparently the reason why Hilda recruited him and a feat that surprised Seth on how someone with very little grasp on their EXS abilities is able to survive out in the Hollow Night.
- Wild Card: As of his Arcade ending, he has disbanded from Amnesia to seek out stronger opponents, meaning he has no allegiance to any of the current factions and serves as neutral party.
- Worthy Opponent: His desire to find one is what led him into the Hollow Night in the first place. He appears to have found a few in Waldstein and Gordeau. He is however unable to fight both of them properly as his fight with Waldstein has Enkidu realize that Wald cannot fully fight to the death because of his duty towards Linne. In Gordeau's case, Enkidu considered Gordeau unfit to fight at his absolute best with thoughts of his late-friend still heavy on his mind.
Erika "Miyashiro" Wagner
Voiced By: Shizuka Ishigami
- She annihilates. Enveloped in the inherited scorching flame.
Admires the name of the clan, takes an oath of the eternal loyalty to Adelheid.
Without forgiving herself. Without loving herself. She only exerts her sword.
Even when goddess smiles upon, her soul is bound to the battlefield.
Treads on the ash of the dead, waits for the judgment at the endless battlefield.
- Height: 160 cm (5'3")
- Weight: 43 kg (95 lbs)
- Blood type: AB
- Date of Birth: May 23rd
- Weapon(s): Fire Brand, Ancile and Aegis
- EXS ability: Flame Tyrant
- Known alias(es): The Void Hunter, The Crimson Knight, Executor no. 4
Wagner possesses the EXS of Incandescencenote : Flame Tyrant, allowing her free reign over fire as well as making her immune to cold temperatures. She goes into battle wielding her shortsword and shield combo of Fire Brand and Ancile, which work in conjunction with her abilities to strengthen her attacks. Her mask, the Aegis, is another one of her armaments. Wagner's Force Function, Schild (German for "Shield"), has her perform a back-handed shield bash that nullifies projectiles and knocks opponents back, stunning them if fully charged. Buffing her shield beforehand grants her Force Function a guard-point that can punch through most opposition that tries to impede the shield bash.
Wagner's Chronicle Mode story is A Saint Appears, which details Wagner's every-day life at school with her attendants Sakurai and Murayama. In the middle of her mundane discussions with them over lunch, she is finally given orders from Licht Kreis' HQ to monitor the upcoming duel between the groups Amnesia and Bankikai. She is also notified that she will not be attending her current all-girls academy any longer in favor of further expanding her perspectives by attending a co-ed school, much to her horror.
- 0% Approval Rating: Virtually everybody that knows of her steers clear of her, including her own allies within Licht Kreis such as Orie and Lex. Even Hilda thinks she's deplorable. Her only real "friends" are her two attendants, Sakurai and Murayama and even their connection with her is questionable.
- Adorkable: She has shades of this in Chronicle Mode, where she's living student life and trying to overcome her lack of social skill.
- Arch-Enemy: Gordeau really hates her and wants her dead for her execution of Roger after he was transformed into a Void. It really isn't personal though. Gordeau is just taking out his frustration at not being able to Mercy Kill Roger. In reality, she saved Gordeau's life.
- Ascended Extra: Was only mentioned by a select few characters at first and never appeared in the actual story outside of Chaos' Arcade ending CG in Exe: Late. She finally made her first on-screen and playable appearance in the console version of Exe: Late[st].
- Big Bad: Of Gordeau's arc.
- Broken Tears: At the end of her arcade mode, Wagner completes her assignment to dismantle Amnesia and leaves the Altar of Light and Darkness and burns it to the ground, with Gordeau and Hilda still inside. As she contemplates that she's just taken two more lives and how she's nothing more than a tool to be used, she walks away with tears in her eyes.
- Char Clone: A rare female version. She's blonde, has a Cool Mask (that she doesn't wear in battle, unfortunately), dresses primarily in red, and sees a rival in Orie.
- Church Militant: As per her duty as an Executor of Licht Kreis, though it veers more into Knight Templar territory.
- Combat Stilettos: Wears knee-high boots with heels into battle.
- Damage Over Time: Possesses a unique debuff in the game that applies a Burn effect on her opponents.
- Everything's Better with Spinning: Her Kugel Blitz and Wachenröder involve drilling through her opponents while she's surrounded with fire. The latter is her Shoryuken-reversal that has her ascend while spinning with fire dancing around the edges of her sword.
- Evolving Attack: She can apply fire to her sword and shield to give them additional effects. These include increased chip damage on her sword-based attacks, frame advantage if her shield attacks are blocked, armor on her shield specials, and follow-ups to her sword drill.
- Face of an Angel, Mind of a Demon: She's quite attractive without the mask, and yet she's much worse than Carmine in terms of sadism and killing intent.
- Fantastic Racism: Granted, it's in the job description for the Licht Kreis to hunt Voids, but Wagner has far more passion for it than is perfectly healthy.
- Finishing Stomp: Her unique grab, "Filthy dog!" While not optimal nor frame advantageous, is a combo ender that can be used to finish out a match in a satisfying manner.
- Foregone Conclusion: Because Chronicle Mode takes place before Arcade mode, the player has probably played through Wagner's Arcade story and already know that Adelheid's plan to get her to break out of her Knight Templar mindset by sending her to have a normal school life is doomed to fail, despite Wagner showing some signs that she might improve. If anything, Adelheid made it worse by making Wagner think the whole ordeal is a waste of time..
- Glass Cannon: In Exe: Late[st], she and Hyde have the second lowest HP totals of the entire cast, with Seth just being the lowest possible below them.
- Gratuitous German: All of her move names, and of course, her surname.
- Hidden Depths: Her Arcade mode ending makes it clear that she's starting to crack from all of the violence and murder she commits for Licht Kreis. Unfortunately, she doesn't actually regret any of the horrible things she's done either.
- Jerkass: Takes great pleasure in cutting the enemies of Licht Kreis down without mercy, and she has a track record of killing its allies as well.
- Kick Them While They Are Down: Her combo-ending "grab" has her step on her opponent and send them flying with a fiery explosion.
- Kill It with Fire: She hunts down Voids with not only a sword and shield but also with formidable fire-based abilities thanks to her Flame Tyrant ability.
- Knight Templar: Extremely ruthless towards her foes, and sometimes her allies, to the point where she killed the Third Executor. Yet she still believes that she fights for a just cause.
- Lady of War: She has the appearance of one, but considering the rest of these tropes about her, the "lady" part rings hollow. She is however a proper "lady" as she comes from an influential family with ties to Licht Kreis that has lasted for multiple generations. Her attendants also address her as "Erika-sama".
- Last-Name Basis: In-game, she is most commonly referred to by her surname, Wagner.
- Leitmotif: "Flame & Destiny"
- Light Is Not Good: Her appearance gives off the imagery of that of a Knight in Shining Armor, yet she's absolutely merciless in her methods.
- Luckily, My Shield Will Protect Me: Buffing her shield allows for her Sturm Brecher and Force function to eat through projectiles and enemy attacks if the move is contested against her. Her regular FF also negates projectiles. A blocked Shield Charge that is buffed gives her a frame advantage.
- No Social Skills: She has lived quite a sheltered life with many amenities coming from her family's influence. While she's not entirely spoiled, her problematic demeanor in her work ethic as well as inability to speak her feelings easily leaves her with trouble making friends. One of the primary reasons she was sent to Japan and made to attend school there was for her to learn a few life-lessons and break out of her narrow world-views. She apparently lacked in this department so much that her cover as a student was just as it was: as an "ignorant rich girl", made easier so she didn't have to act. Her Chronicle Mode chapters do reveal that she is trying to get better. She is also notably aware that her narrow hyper-focus when it comes to missions is one of the biggest hurdles she has there, as she keeps getting distracted and sidetracked.
- By her arcade mode ending, she's basically given up on trying to fix this and goes full throttle into her Knight Templar worldview, vowing to kill everyone in the Night Blade.
- Playing with Fire: Her EXS ability, Flame Tyrant, gives her control over fire.
- Red Eyes, Take Warning: She has red eyes which she typically hides behind a mask, the first red flag that something is seriously wrong with her.
- Red Oni, Blue Oni: As mentioned in Orie's folder, she's the red to her blue which is even reflected in their clothing. The two are frequent sparring partners and Wagner treats the relationship as a one-sided rivalry while Orie never sought to compete with her.
- Shield Bash: Her Force Function and Shield Charge.
- Superpowerful Genetics: Dialogue between her and Orie as well as her introductionary text imply that Wagner's Flame Tyrant ability has been passed down from someone else in her family.
- Team Killer: Sometime before the story, Wagner killed Licht Kreis' Third Executor for unknown reasons.
- The Rival: She views Orie as one while the latter has no idea why they need to compete against each other. Chronicle Mode reveals it may be for the sake of keeping up appearances, however.
- Token Evil Teammate: For Licht Kreis, where it's stated that she even killed the Third Executor.
- Tornado Move: Her EX Lohen Garde will cover her in a pillar of flame that buffs both her sword and shield, as well as dealing damage to those caught up in it.
- Who Wears Short Shorts?: She wears these, but unlike Mika's, her's hug her body tight.
