Live actors: Yuya Matsushita (older Waver), Shinichiroh Ueda (younger Waver)
The title character of the series, having grown in the ten years since his life-changing experience in the Fourth Holy Grail War as the current professor of Modern Magecraft and acting head of the El-Melloi house.
- Adaptational Attractiveness: Though it's not as if he's outright ugly, his portrayals in older character materials and other franchise entries* tend to depict him rather haggard-looking, making his status as a Chick Magnet more of an Informed Attribute. Meanwhile, due in part to Depending on the Artist, his features in the Case Files novels and especially its various adaptations aren't quite so harsh, stress lines notwithstanding.
- Adopted into Royalty: Waver comes from a working-class background but was formally adopted into the El-Melloi II family by Reines, mostly so she could ruffle other lords' feathers by forcing them to treat a third-generation mage as a peer. It also conveniently put the responsibility of paying off the family's rather terrifying debt onto him, which Waver isn't exactly happy about.
- Amateur Sleuth: Though a magic professor by profession, he spends quite a bit of time solving mysteries.
- Ambiguously Gay:
- Waver is entirely uninterested in women to a level that Gray comments on, and which Adashino links to his obsession with reuniting with Iskandar.
- When Flat offers him a strategy guide for a bishoujo game to cheer him up under the assumption it's the kind of thing men like him would enjoy, he's downright offended to the point of physical violence.
- In the anime, Melvin wonders if he lost his virginity during Zero (i.e., thanks to Iskandar), which an embarrassed Waver angrily denies; when Reines asks him if he's a virgin three years later, his response is an annoyed "who cares?".
- Likewise, Kairi draws explicit parallels between him and Wills, who is noted to be in love with and captivated by a supernatural being bound to another realmnote .
- Aristocrats Are Evil: Zig-zagged. He was not born into nobility and, in fact, comes from a very undistinguished background. But after surviving the Holy Grail War and being named Lord El-Melloi II by Reines until she comes of age, he is easily the most moral and scrupulous of all of the Lords of the Clock Tower.
- The Atoner: He picks up the pieces that were left behind after Kayneth was killed and the El-Melloi faction was on the brink of ruin, as he acknowledges that he was partially responsible for the death of Kayneth and Sola. The heir to the El-Melloi faction, Reines, eventually makes him restore the Archibald family's Magic Crest, pay off their debts and become her personal tutor. To bind him to her, she also adopts Waver into the family as her step-brother and grants him the title "Lord El-Melloi" until she comes of age.
- Attack Reflector: He wears his hair long so that he can cut off parts of it to redirect magical attacks towards the ground in a hurry.
- Awesomeness by Analysis: Lord El-Melloi II can "dissect" the symbolism of a magus's magic - what system it uses, what power sources it uses, what kind of power it uses. He then deduces what the magic can do and what it has already done. He usually does this to solve cases. Most mages feel this destroys the "Mystery" of magic and damages magic in general, but he can also instruct a mage in how to use their personal magic far more effectively.
- Badass Baritone: He speaks with a surly, matured tone as a sign of his increased age and experience with an appropriately deeper voice. But his old voice from the Fourth Holy Grail War tends to leak out when he's surprised.
- Badass Bookworm: After he returns as a lecturer at the Clock Tower, he quickly gains a reputation as a practical and superior instructor. The El-Melloi heir eventually recognizes his achievements, orders him to serve her as her personal tutor and makes him Lord El-Melloi II, the youngest Lord of the Clock Tower in its entire history.
- Biseinen: Waver has grown up to be a very pretty man between his flowing hair and angular features.
- Boomerang Bigot: Waver is a mage who is openly contemptuous of mages as a class, both out of justified disgust for their frequent sociopathy and out of intense jealousy of their power.
- British Accents: In Accel Zero Order Kayneth notes that he has traces of a working-class accent (i.e. Cockney or Estuary) in his speech. Neither his Japanese nor English voice actors actually give him one, though.
- Byronic Hero: Flat invokes this, insisting that Waver is basically a protagonist from the tradition of Romantic literature, "just like Sherlock Holmes and Jack the Ripper." Neither Waver nor the other students are flattered by this comment.Svin: Did you just compare our professor to a serial killer!?
- The Cameo:
- He makes an appearance in a bonus chapter of Fate/kaleid liner PRISMA☆ILLYA 2wei. It was early on adapted in the anime of the first season, making it his first anime apperance as Lord El-Melloi II.
- Appears briefly in the 2015 Fate/stay night [Unlimited Blade Works] anime (as Lord El-Melloi II) to have a short conversation with Shirou. Despite not managing to exchange names, Shirou and Waver seem to mutually understand and respect how their experiences of participating in the Holy Grail War made them realize their ideals—and what they should do to attain them.
- He also appears in the first episode of the Fate/Apocrypha anime alongside Flat Escardos to provide exposition for the concept of the Great Holy Grail War. He returns in the final episode to take Caules Forvedge Yggdmillenia under his wing as his newest student after the war is over.
- Celibate Hero: Waver has no interest in any romantic relationship and is more interested in living his life in a way that lives up to Iskandar's legacy as his loyal follower.
- Character Development:
- Much of the first half of the anime involves El Melloi II/Waver's attempts at living his life the way he feels honors Iskandar best. However, his ways of going about it leave him frustrated and feeling inadequate (much like Shirou Emiya struggling with his inherited "hero of justice" ideal from Kiritsugu, especially as shown in Fate/stay night [Unlimited Blade Works] and Fate/stay night: Heaven's Feel). His supportive students, friends and colleagues being around him slowly but surely break him out of it, such that by Episode 12, he can face Dr. Heartless and "Hephaestion"/Faker, finally realizing that Iskandar's life and actions aren't as insurmountable as he made them out to be, and declare that beating them both is about as good as surpassing Iskandar himself.
- Waver starts the series desperately trying to find a way to enter the Fifth Holy Grail War in order to meet Iskandar again and realise his King's dream due to his guilt over Iskandar's death. This is in spite of the very real possibility that Waver could die and despite the fact that the Iskandar summoned of the war would have no memory of their time together. By the end of the Rail Zeppelin arc Waver willingly withdraws from being selected for the war and instead of focusing on his past mistakes decides instead to embrace the future, as his king would have wanted, and resolves to do so by defeating Dr. Heartless and Faker, who are both using Iskandar's power for nefarious ends.
- Chick Magnet: Is noted to be extremely popular with the female students of his class, and has the affections of at least Yvette and possibly Gray.
- Cigar Chomper: Rarely seen not smoking a cigar. The cigars he carries are actually a type of Mystic Code he created, with the tobacco inside them having different purposes depending on the cigar. The reason why he specifically uses cigars is because when he was looking for ways to appear more Lord-like, a drunken magus told him that "A cigar and a suit are a mans weapons".
- Classy Cravat: It helps him fit the image of a Lord of the Clock Tower, although in private he'd rather wear a t-shirt for hanging around in his tiny, unkempt apartment playing video games.
- Comic-Book Fantasy Casting: Bore a heavy resemblance to Severus Snape in his original appearance◊, along with the surly disposition to match. Adaptations maintain this to varying levels, although from Case Files onward he's migrated away from this due to Depending on the Artist and Takeuchi's own Art Evolution.
- Defective Detective: He's haunted by grief for Iskandar, drinks heavily when stressed, and has such poor self-care skills that he needs Gray to brush his hair for him. At the beginning of the Adra Castle case, he's tempted to commit suicide rather than face the possibility of being killed by another mage (the fact he's the weakest mage in the building doesn't help). Psychologically, he's in rough shape. Plus, he has the typical troubled-detective quality of being brusque and prickly even with the people he cares about.
- The Dreaded: His ability to almost instantaneously deconstruct magic and rob it of its Mystery has certain mages wary of his presence.
- Embarrassing Nickname: Much to Waver's chagrin, Flat's nicknames like 'Professor Charisma' and 'Great Big Ben London Star' have made their way throughout the entire school.
- Experienced Protagonist: Lived through life-or-death situations in the Grail War a decade ago, and came out alive.
- Expository Pronoun: Usually refers to himself in the first person with the neutral formal watashi, but slips back into the boyish and more immature boku when particularly annoyed.
- Foil: To EMIYA. Though their personalities are very different, both are heavily jaded masters who survived the Holy Grail War and spend their lives attempting to live up to a lofty ideal to honor the memory of a dead man. Amusingly both also go through dramatic late growth spurts. However, unlike EMIYA, despite all his bitterness Waver never shows any regret towards his path in life. In the last episode of [Unlimited Blade Works] he understands Shirou's dream of being a hero of justice is both foolish yet admirable, which Case Files shows is due to his own experiences trying something similar immediately after Zero. In Fate Accel/Zero the relationship between the younger and older versions of Waver mirrors that of Shirou and EMIYA.
- Geek Physique: Described as being scrawny from preferring his studies to exercise back in Fate/Zero, and the same holds up into adulthood. Even before he gets his shirt off he's on the thin side, and definitely not in the best of shape considering that a simple walk leaves him winded.
- Genre Savvy: Waver is a fan of detective novels, and even uses detective novel jargon when speaking about his investigations. He's also genre-savvy enough to know that, in a magical world, there are many detective novel tropes that don't apply to the situations he gets into and thus should be eschewed.
- Gratuitous English: Tends to swear in English when he gets especially angry, and utilizes colloquial English detective terms for his investigations.
- Green-Eyed Monster: Part of his annoyance with Flat is that Flat is unbelievably talented but uses said talent to mess around which aggravates Waver due to his own lack of talent.
- He Is All Grown Up: Following the 4th Grail War, Waver hits a major growth spurt that turns him from a short, mousy nerd into the Tall, Dark, and Handsome lust object of many a female student.
- Hell-Bent for Leather: Prominently wears form-fitting black leather pants as part of his main outfit as an indication of his strong sense of fashion.
- Hero-Worshipper: Essentially the crux of his relationship with Iskandar. Waver has spent his life after the Fourth Fuyuki Holy Grail War trying to live up to Iskandar's legacy so he can hold his head high as Iskandar's follower.
- Heroes Gone Fishing: He's an avid videogame player.
- Heroic Self-Deprecation: He believes that his experiences during the Fourth Fuyuki Holy Grail War were a complete wash due to how he was of only nominal use to Iskandar and wishes to vindicate his perceived failure vis-a-vis joining the Fifth Fuyuki Holy Grail War.
- History Repeats: As it was with Kayneth, the enemies of Lord El-Melloi wind up putting Waver into a wheelchair albeit temporarily.
- Hot Teacher: If one of Flat's other nicknames is to be believed, he has apparently become very popular with his female students; they even voted him the number one man they'd have a relationship with.
- Humble Hero: He's outright annoyed with the prestige and popularity he's gained as Lord El-Melloi II after the War, because he wants to be recognized for his personal efforts as a magus rather than a teacher with extraordinary students.
- I Just Want to Be Special: Despite being able to explain magic and even explain to other magi how to make their magic better, Waver is not particularly special. He seems to have accepted his lot in life by this time in the series.
- Identical Stranger: Turns out that Waver looks extremely similar to Iskandar's general Eumenes◊.
- In Spite of a Nail: He somehow becomes Lord El-Melloi II even in timelines where the Fourth Grail War doesn't occur, but it's not mentioned how.
- Incompatible Orientation: It's not stated explicitly whether it's because he's gay, Iskandar-sexual, or just asexual (although it's implied he might not be a virgin anymore), but Gray and Reines seem to think his lack of interest in women is categorical. He mentions being nervous around beautiful women the first time he meets Adashino, but it's mostly an excuse to not have to talk to her, and she immediately thinks he's full of it.
- Inopportune Voice Cracking: Usually he speaks in a very smooth, low voice, but from time to time his voice cracks back into the higher-pitched one he had as a teenager. Possibly symbolic of how he still holds onto a spark of youthful hope and innocence, or a reminder that he only recently finished going through what seems to have been an unusually delayed puberty... or maybe it's just really funny.
- Internal Reveal: Was unaware Sola-Ui had also died in Fuyuki until Reines informed him three years later. As far as he (and most anyone in the Mage's Association) knows, Saber killed both Kayneth and Sola as participants in the Grail War.
- It's All My Fault: Episode 1 reveals that he feels Kayneth's death was his fault for stealing Iskandar's relic that Kayneth planned on using. As a result he bought Kayneth's class, because while he hated him, he did learn a lot in that class and wanted to give future students a place to learn like he did.
- Jerk with a Heart of Gold: Is very bitter and insulting. Nevertheless, he tries to do what is right from a human standpoint and not a Magus's, no matter what he says otherwise.
- Kid Hero All Grown Up: Has grown considerably, both physically and mentally, since his time in Fate/Zero.
- Knight in Sour Armor: As much as he despises the brutality of mage culture and realizes that his own quest to reach the Root is futile, and as reluctant as he is to rock the boat too hard, he nevertheless continues on as a teacher so that he can inspire others the way Iskandar inspired him.
- Long-Haired Pretty Boy: His hair grows longer and longer as the years go by after Fate/Zero, he's on the slim side, and he's quite popular with the ladies (and Flat). Unusually, the long hair has practical purposes as he can use it to store and channel mana, much like Rin explained in the original Fate/stay night
- The Mentor: Takes on this role for his students in the classroom, guiding them both in magecraft and personal growth. He's renowned for how good he is at teaching, with all of his students becoming first-rate magi before they turn 21. He's less interested in this and more in his own personal growth, but that doesn't stop him from earning accolades for his work.
- The Mourning After: Still suffers from the guilt and trauma of Rider's death a decade ago. Kairi actually calls him out on it, telling Gray to watch over him due to his preoccupation with a dead man.
- Mr. Exposition: The primary source of world building on magic and the mystic as his analytical skills and wide berth of knowledge allow him to pretty much explain the fundamentals of any given topic.
- Muggle with a Degree in Magic: Not that he can't use magecraft, but his abilities are average at best. However, as a teacher he's first-rate, and has an unusual aptitude for figuring out the secrets of others' magecraft.
- My Greatest Failure: Towards the end of the Grail War, he could do nothing but see Iskandar get killed by Gilgamesh. When alone, Waver laments he didn't help Iskandar see his dream of world domination come true.
- Neck Lift: While Waver is not a strong man by any means, he has learned how to use reinforcement magecraft just well enough that he can lift Flat a foot off the ground with an Iron Claw just to show how mad he is at him.
- Non-Action Guy: Waver is not especially athletic, and his natural capacity for magecraft is far below that of most magi, so it's up to Gray to handle more physical confrontations.
- Not a Morning Person: He very much isn't. In one scene, he tries changing his clothes in the morning without standing up, opening his eyes, or apparently waking up at all. When Gray tries to wake him on the Rail Zeppelin he curls up in his blanket and asks for more time.
- Not Distracted by the Sexy: One of the All Around TYPE-MOON drama CDs has F/SN's Rider attempting to seduce him. He's completely disinterested... until she starts quoting Iskandar, at which point his ears perk up.
- Occidental Otaku: He has a well-known preoccupation with Japanese video games. He was quite excited to learn that one of the students he was sponsoring was actually Japanese... until he discovered that she knew absolutely nothing about Akihabara or otaku culture. Said student was Rin Tohsaka.
- Older and Wiser: Has it much more together than a decade previously, easily weathering snide comments and mage politics. This doesn't mean he's any less hot-headed in private, however.
- Only Known By His Nickname: Waver is almost never referred to by his real name, even in narration.
- Parental Substitute: To Flat and Svin. While Waver teaches most students, he functionally raised those two from the age of nine.
- Perpetual Frowner: His most noted characteristic.
- Platonic Life-Partners: With Gray. He doesn't have any romantic feelings for her, being largely uninterested in anyone that way (which is suspected to be down to Iskandar), but he does sees her as his student and apprentice.
- Politically Incorrect Hero: He's that type of otaku that loves what Japan has to offer, but doesn't quite like the Japanese themselves. The above incident mentioned in Occidental Otaku ends with Waver exclaiming that she's "the worst Japanese there" after she tells him what he didn't want to hear.
- Precision F-Strike: He uses one when he finally reveals how he'll beat Touko's monster. It's in Gratuitous English just to make sure even the audience knows what's intended.
- Rapunzel Hair: He has let his hair grow past his waist, and holds the position of a prim and proper noble, at least in public.
- Raven Hair, Ivory Skin: Most official art depictions indicate that his hair is supposed to be some kind of black, but often with tints of various colors. The manga and anime go directly for jet-black hair and contrasting pale skin in conjunction with Adaptational Attractiveness.
- Self-Made Man: A major cause of tension between Waver and the rest of The Magocracy is that he comes from a very undistinguished background in a society that takes class matters to the point of eugenics.
- "Shaggy Dog" Story: Festered resentment for years over the notion that Iskandar should have won the Fourth Holy Grail War, tragically ignorant of the fact that the prize was literally a poisoned chalice.
- Shell-Shocked Veteran: The origin of a lot of his psychological baggage. He went to a Grail War seeking glory and fame through Wizard Duels, but bit off more than he could chew, instead coming home with bucketloads of trauma, Survivor's Guilt, and PTSD.
- Shoe Phone: Some of his cigars are disguised Mystic Codes that he can innocuously carry on his person with his regular kinds.
- Sir Swears-a-Lot: Tends to curse in Gratuitous English whenever he gets pissed off, which is pretty often.
- Stern Teacher: Especially toward Flat, his most disruptive student. But when Flat causes trouble, Waver might go so far as to triple everyone's homework. Nonetheless, he actually cares about his students' education and well-being, unlike his colleagues.
- Student and Master Team: While very intelligent and well-versed in magical theory and technique, Waver's powers as a magus are completely dwarfed by most of his students. As a result, he regularly has to rely on his students to be the muscle that takes down the enemies that he susses out through his investigations. He generally provides tactical support by explaining enemy powers and weak points, when he isn't able to talk the monster to death.
- Surpassed the Teacher: Nope. At least not as a mage. Kayneth wasn't wrong when he said that one cannot overcome the generational gap between mages just with proper education, as Waver stays a mediocre mage. He inherits Kayneth's Mystic Code, Volumen Hydragyrum, reworks and upgrades it into a Meido Automata bodyguard for Reines and widely becomes known as a great instructor and the youngest Lord the Clock Tower has ever seen, but his most famous work is also just him finishing Kayneth's research and organizing it into a single encyclopedia.
- Tall, Dark, and Snarky: He's very tall, prefers dark clothing, and is considered attractive by most of the Clock Tower and just as insufferably arrogant, particularly by the aristocratic faction.
- Team Dad: While he's rather gruff and sometimes even physically abusive with his students, he also notably took in Flat, Svin, and Gray when their own families wanted nothing good to do with them. Gray also notes from his interactions with Rosalind that he's rather good with children.
- They Call Me MISTER Tibbs!: He dislikes when people address him without the "Second" suffix because the name is unbearably grating without it.
- Token Good Teammate: He's the most moral and honorable of all of the Lords of the Clock Tower. He refuses to involve innocents unless absolutely necessary and keeps collateral to a minimum. He imparts these ideals onto his students, who are all more moral than the average magus as a result.
- Tragic Keepsake: He kept Iskandar's belongings with him, and even occasionally wears Iskandar's t-shirt at home.
- Trauma Button: Seeing Altria, or anyone who looks like her, a result of his run-in with her in Fate/Zero. His reaction to reading about Gilgamesh in episode 6 strongly suggests most anything that reminds him of Zero is this for him, aside maybe from Iskandar.
- Tsundere: And how! Somehow he manages to pull this off towards a cat. Though he's naturally surly and acts exasperated by his students, especially Flat, he cares a lot about them and is very proud of their accomplishments, almost crying in happiness when Svin graduates. He also has a habit of berating Iskandar in narration even when he's speaking fondly of him to others.
- Underestimating Badassery:
- Having actually seen the real Hephaestion in Iskandar's Reality Marble, Waver knows that Faker isn't who she claims to be, but is almost at a loss when she summons a dark version of the Gordius Wheel to attack him and Gray.
- On the other hand, most other aristocrats assumed he'd be a weak-willed puppet of Reines', but he ended up being quite deft at the position and inspiring loyalty in his students to protect him from the various assassination attempts since.
- Undying Loyalty: To Iskandar. He calls himself Iskandar's loyal follower and wants to enter the Holy Grail War to both meet Iskandar once more and grant his wish this time.
- Unwanted Harem: Downplayed, because it's not the focus of the series and is mostly implied, but Waver appears to draw quite some attention, both platonic and romantic, from his friends and students regardless of gender, although he's not interested in a relationship (or at least not with them).
- Walking the Earth: After the events of Zero he traveled the world until he was taken in by Reines.
- Weak, but Skilled: Is notably very untalented in magecraft and thus forced to rely on mundane strategies, observation, and the abilities of those he's mentored. Also applies to him physically, as he gets easily winded by long walks.
- When He Smiles: Considering what a dour man he usually is, the rare moments when he's genuinely smiling in the anime are all the more notable for it, as Gray herself comes to appreciate.
- You Are What You Hate: While he resented Kayneth's severe teaching methods during his youth, he finds himself being similarly harsh (if more open-minded) towards his own students to the point that he's liable to physically assault them.
- You Remind Me of X:
- Younger Than They Look: It's difficult to tell due to the wrinkles and his general cantankerousness, but Waver is in his late 20s for a majority of the series.
Voiced by: Reina Ueda (Japanese), Kayli Mills (English)
Live actor: Saho Aono
El-Melloi II's apprentice from the countryside.
- Action Girl: She's the primary physical combatant among the main cast.
- The Ageless: One of the effects that Saber being summoned in Fate/stay night had on her body was to halt her aging, just as Saber's was halted. In the sequel series The Adventures of Lord El-Melloi II, Gray still looks 15 even though she's actually 18.
- Ambiguously Bi: Gray's great admiration towards Waver includes what seems to be a crush in the anime (non-existent in the novels). She also finds Adashino and Luvia's beauty quite arresting on multiple occasions, and thinks to herself about how handsome Melvin is.
- The Apprentice: She's Waver's magic apprentice.
- The Artifact: Apart from having the Saberface character design typically displayed in all Fate anime, she is also the only one of the main cast that fights like a Servant rather than a magus through pure strength and a mystical weapon of legendary repute. In spite of being a series not directly connected to the Holy Grail War, her appearance and existence make it clear the Holy Grail War is still important in Waver's life besides his expressed urge to fight in it once more as an active reminder of the sacrifices and trauma created ten years ago.
- Battle Butler: Not only does she fight Waver's battles, she also gets his groceries, shines his shoes, makes his tea, and generally does everything Waver's too busy or can't be assed to do himself—up to and including brushing his hair.
- Because You Were Nice to Me: The reason for her loyalty to Waver. Oh, the people of her village may have been nice to her, but that was because they saw her as a vessel rather than a person. Despite (or because of) Waver's disdain for her face and original intention to recruit her as a soldier for the Grail War, he's the first one to acknowledge her as an individual, which spoke more to her than her family's false kindness.
- Bit-by-Bit Transformation: She's been slowly transforming to be more like Altria in every aspect after Fate/Zero. She's terrified of fully succumbing to the transformation because of the potential Loss of Identity from Altria taking over her body.
- Body Horror: The transformation process that turned Gray into a Saberface is described as excruciatingly painful and includes the bones of her skull audibly cracking and twisting themselves to resemble Altria's. In volume 3 she recalls how ten years ago while it was occurring she stayed up all night in agony, hugging her pillow.
- Book Dumb: Gray has a bit more trouble keeping up with her fellow students when it comes to understanding magecraft. Justified in that she isn't even a Magus and had no real idea about the Magus world due to her Gilded Cage past.
- Conditioned to Accept Horror: Her experiences with the dead and her childhood mean she's not particularly perturbed by situations like eating breakfast with a pair of disembodied eyes watching her the whole time. However, she does kinda feel bad when watching horror movies with Reines because she has the feeling that she should have actually reacted to the horrors.
- Country Mouse: Grew up in the countryside and thus a bit uncomfortable in the crowded metropolis that is London.
- Dark Is Not Evil: She dresses all in black and her Weapon of Choice is a Sinister Scythe, but she's unquestionably one of the good guys.
- Dragon Ancestry: Although she has a family connection to Altria, it's so distant she gains none of Altria's Dragon Factor. However, in the last volume when Altria is summoned in Fuyuki, Gray finally inherits her Dragon Magic Core in the process of becoming the perfect copy of King Arthur.
- Expository Pronoun: She uses "setsu" as a first-person pronoun, which is considered self-deprecating and old-fashioned.
- First-Person Smartass: She mostly acts like a Shrinking Violet out loud, apart from occasionally suggesting Waver might be on drugs and such, but in her narration she's mercilessly critical of most people: mages are just looking for excuses to be shut-ins, Waver is unlikeable, Melvin has an Oedipus Complex, etc.
- Freakiness Shame: An odd example. Most people don't know the story behind Gray's face or why she hates it (namely that it's not her original face and it prompted the villagers of her hometown to groom her as a sacrificial vessel for the second coming of Altria) or recognize her resemblance to Altria Pendragon at all, so they simply assume she's just a very pretty girl who is inexplicably convinced she's ugly. The one exception is Waver, as he fought Altria in the fourth Holy Grail War and now finds her face to be a Trauma Button. As a result, Waver is the one person who can't stand looking at her any more than she can, a fact she quite appreciates.
- Gilded Cage: Grew up in one, as she was groomed to be the host of a resurrected King Arthur. In the prologue of volume three, she recalls a "pampered" life where she was treated as "special" with parenthetical readings that indicate she really means something much more sinister.
- Gratuitous English: Speaks in English while using her Invocation.
- Heroic Self-Deprecation: She really doesn't think very highly of herself, berating herself for being clumsy or ignorant of a topic at hand.
- I Owe You My Life: The people of her village were going to have her soul overwritten with Altria's. Waver looked for her after he heard about it and he took her under his protection. For this, Gray considers Waver her savior.
- Ironic Fear: A gravekeeper scared of ghosts. The villain of the Adra Castle case starts laughing at the irony when he finds out.
- I See Dead People: She's a Sybil, especially versed in spiritual possession; as one of the side-effects of this, she found herself dreaming about Hephaestion's memories. This nature also makes her much more sensitive than others to the the negative thoughts and emotions of ghosts, which leads to her aforementioned fear of them.
- Identical Granddaughter: Gray is the descendant of one of Altria Pendragon's distant relatives and basically looks like a grey-haired version of her. She didn't always look this way, but, in fact, started transforming into a copy of Altria after Altria was summoned as Saber in Fate/Zero.
- The material book's glossary explains that while it's not a handwave, it would be more accurate to say her family was imprinted with the essence of Altria's physical body (that is, magical genetic engineering).
- Idiot Hair: Along with having the same face as Altria's, she also has her ahoge.
- I'm Not Pretty: She hates it when other people see her face and gets flustered when Reines calls her cute, asking Reines to stop teasing her.
- In the Hood: She wears a cloak with a hood, which she uses to hide her face from others out of shyness and El-Melloi II's discomfort from seeing Altria's face.
- Invocation: She has one for invoking Add's scythe form and Rhongomyniad's powers. It's written with Alternate Character Reading similar to a Noble Phantasm, saying two things at once.Gray (Dark), Rave (Unsteady), Crave (Desire), Deprave (Degradation)
Grave (Engrave) me (in me)
Grave (A grave) for you
- Locked into Strangeness: By the last volume her hair has started to turn blonde as her body grows closer and closer to being a perfect clone of Altria's. It was caused by Saber being summoned by Shirou, which happened on the same night as this series' final battle.
- Loss of Identity: She's terrified of the possibility of Altria taking over her body as she gradually becomes more identical to her.
- Magic Enhancement: Through the use of Add, she can absorb magical and spiritual energy (such as from spells or spirits) in order to boost her strength, durability, and speed beyond what Reinforcement magic can achieve. And when Altria is summoned in Fuyuki, Gray transforms further and inherits her Magic Core, allowing her to use Mana Burst.
- Magic Skirt: Despite often fighting in a Dangerously Short Skirt, the manga and anime take care to only go in so much as having a Male Gaze of her legs and never compromising Gray's modesty.
- Morality Pet: Gray appears to be the only person Reines seems to sincerely like rather than view as an object of amusement.
- Morph Weapon: Her Mystic Code, Add, can transform into a variety of different forms. The ones we know about include her iconic scythe, a bow with arrows, a jet-powered hammer, a tower shield, a lance/halberd, a giant bladed boomerang, and a large kusarigama/grappling hook. Though it hasn't been seen, her profile in Grand Order Material also mentions a greatsword form that's an imitation of Excalibur. This is all in addition to Add's true form of Rhongomyniad.
- Mystical White Hair: As if her silver hair didn't make her stand out enough, she has a family connection to Altria Pendragon, better known as King Arthur. Because of her striking resemblance to Altria, she was believed to be a vessel to resurrect the legendary king.
- Nice Girl: Although she can be aloof and shy, Gray is a sweet girl who gladly puts her life on the line to protect the people she cares about and shows deep concern for others.
- No Hero to His Valet: Though she respects his ability as a teacher, Gray tends to find Waver exasperating rather than impressive, what with being the one who has to drag him out of bed in the morning.
- Oblivious to Love: The way Svin acts around her makes her think he hates her when it's obviously the opposite.
- Only One Name: 'Gray' is the only name she goes by. Whether she has, or had, any other names is unknown. It seems to be a family thing, as her mother's only known name is Magdalena.
- Platonic Life-Partners: With El-Melloi II, as her mentor and professor.
- Raised as a Host: The people of her village, including her own mother, groomed her to be a vessel for Altria Pendragon after her face became identical to her ancestor's. They would have performed a ritual to summon Altria's soul and place it in Gray's body if Waver hadn't intervened.
- Raised Catholic: Doesn't personally believe in God, but she's familiar with Christian prayers and practices due to being educated by the resident priest of her village, and sometimes prays for others and performs the sign of the cross out of habit.
- Reused Character Design: Her family has a distant connection to Altria Pendragon, and she looks exactly like her. Waver keeps her In the Hood because her face brings him traumatic memories. Having a reused design was not the case prior to the events of Fate/Zero, as when Saber was summoned Gray began changing to look like her.
- Servile Snarker: While Gray oftentimes gets exasperated by Waver's less than admirable traits and will sometimes give him various backhanded remarks, she still has a deep respect for him since he saved her from her village, and as such has developed Undying Loyalty towards him.
- Shipper on Deck: Much more so in the novels than in the anime. After catching Waver mournfully talking to his mantle and realizing what Iskandar means to him, Gray considers her desire for the two to reunite is the first earnest wish she's had since coming to London, and frequently speaks in defense of or ruminates on Iskandar's importance to him.
- Shrinking Violet: Reserved, timid and lacking in the self-esteem department.
- Sinister Scythe: She wields one formed from Add, her Mystic Code. It can absorb spirits and boost her physical abilities.
- Smells Sexy: Svin finds Gray's scent to be wonderful. He often describes it as having certain colors and textures.
- Socially Awkward Hero: Gray's upbringing didn't exactly prepare her for socializing, and she often spends discussions hiding behind Waver and hoping no one tries to address her directly.
- Spell My Name with an "S": Though she was raised and lives in the UK, Gray's name uses the American spelling in official translations. The author has explained that he ultimately picked the American spelling to emphasize that she's an exact middle between black and white rather than being paled out.
- Supernatural Gold Eyes: Usually, Gray's eyes are teal/aquamarine. Whenever she chooses to deploy Add's scythe form or fully release Rhongomyniad, her eyes turn gold. Together with her near-monochromatic fashion sense and hair, she looks the near-spitting image of Saber Alter, further emphasizing her connection with King Arthur.
- Undying Loyalty: To El-Melloi II, who rescued her from her village and who also shares her dislike of her reconfigured face. As such she is devoted to helping him however she can, sometimes to unhealthy extents, and gladly serves as his muscle.
- Unlimited Wardrobe: Although she always tends to wear concealing grey clothes with a skirt and hood, she has worn numerous unique variations of her outfit, changing outfits for each volume arc. Even the outfit she wears in Fate/Grand Order is a new one that only appears there.
- The Watson: Because of her sheltered upbringing, other characters need to exposit about magecraft, magic society, or any other subject that's been brought up for her. She explicitly acknowledges her role is similar to Watson in the prologue to volume 1.
- Why Did It Have to Be Snakes?: Ghosts. As said above she's conditioned to a lot of other traditionally scary stuff and doesn't get scared watching horror movies, but due to her sensitivity to them ghosts absolutely terrify her. When attacked by a swarm of them at the end of volume 1 she's so scared that she can't even move her body, and just keeps repeating over and over in the narration how terrified she is.

Gray's chatty and very annoying Mystic Code.
- Ancestral Weapon: He has been passed down for generations of Gray's family, dating back to the reign of King Arthur. According to Case Files Material his creator was Morgan le Fay, Altria's archenemy sister.
- Blade on a Stick: While he normally takes the form of a Sinister Scythe in combat, he's actually the sealed form of Rhongomyniad, the lance of King Arthur.
- Godzilla Threshold: It's revealed that he's El-Melloi II's last resort, as Add's true form is Rhongomyniad, a Noble Phantasm at least as powerful and destructive as Excalibur.
- Living Weapon: He transforms into a scythe that Gray uses in combat, as well as a bow with arrows, a jet-powered hammer, a tower shield, a lance/halberd, a giant bladed boomerang, and a large kusarigama/grappling hook. This is in addition to Add's true form: Rhongomyniad, the spear of King Arthur.
- Meaningful Name: Rhongomyniad.
- Only Friend: Rather depressingly, Add was Gray's one friend before she joined the El-Melloi classroom because he was the only one who would regularly talk to her after her transformation.
- Power Limiter:
- Add keeps Rhongomyniad's power from leaking out and deteriorating; without him it would have run out of power a long time ago. According to Grand Order, he also prevents Rhongomyniad from turning Gray into a goddess like prolonged exposure to the spear does to Altria in Grand Order.
- And of course, Rhongomyniad itself has thirteen seals placed on it by the Knights of the Round Table—much like Excalibur Proto has in another universe. In Rail Zeppelin, Gray undoes the seals left by Lancelot, Kay, Bedivere, Agravain, and Gaheris in her clash with Faker.
- Shipper on Deck: He's not afraid to take jabs at Gray regarding her admiration of Waver. He even tells her to kiss Waver while he's asleep on the couch.
- Talking Weapon: He's a unique Mystic Code in that he has a personality and can talk. And unlike Trimmau, Add isn't running on a very basic personality program, he can uniquely react to the situation with his own barbs and jabs. He only started talking after Gray's transformation, which was a sign that the cult was making good progress in their plan to bring King Arthur back.
- Uncanny Valley: In-universe. His movements are described in the narration of the novels as looking like CG from a movie.
- Verbal Tic: Frequently uses "ihihihihi" at the beginning of a sentence. Kay uses it in his first appearance and ascribes that to his personality mixing together with Add's.
- Virtual Ghost: Add's personality is based on a replica personality of Sir Kay, one of the Knights of the Round Table and Altria's big brother. During the Atlas Contract arc, Kay is summoned from within Add, but he's not exactly a Servant and more an example of this.
- Walking Spoiler: As you can see, saying pretty much anything about Add that isn't his Morph Weapon nature is a spoiler.

Live actor: Kaho Amasaki
Kayneth's niece and heir apparent to the El-Melloi family, her inexperience and young age has led to her appointing Waver as her new "brother" and lord in her stead to manage affairs.
- Ambiguously Bi: She thinks Gray is very cute and, if nothing else, seems to be going for a Romantic Two-Girl Friendship dynamic with her even though Gray is too shy to actively reciprocate. But she also thinks Svin is very, very good-looking and considers Melvin to be frustratingly attractive. In contrast to her prurient teasing of her adoptive brother, though, it's all very innocent and young-teenager-ish.
- Annoying Younger Sibling: She treats Lord El-Melloi II as her elder brother and takes every opportunity she can to make him miserable.
- Ascended Extra: Originally only hinted at in El-Melloi II's profile in Character Material and making a very minor appearance in Fate/Apocrypha, Case Files bumps her up to one of the lead characters and fleshes out her character substantially.
- Bad People Abuse Animals: In the second volume, Reines compares her enjoyment of Waver's suffering to the pleasure she felt when first dismembering a frog as a child.
- Card-Carrying Villain: Reines is proud to be a complete asshole, to the point that the very first words of the book she serves as the perspective character for are: "I am, quite frankly, a terrible person."
- Control Freak: Like every Lord, she has an innate desire to be in control.
- Crazy-Prepared: Early life as a magus has taught her to always carry requisite emergency supplies on hand in case of whatever danger shows up.
- Devil in Plain Sight: She makes it no secret that she loves making other people suffer, causing almost anyone who knows, especially Waver, to refer to her as a demon.
- The Don: Reines is basically a magic mafia boss in the body of a fifteen-year-old girl.
- Enfante Terrible: Reines has been an unrepentant little hellspawn from the day she was born and was acting like a heartless crimelord by the age of nine.
- Face of an Angel, Mind of a Demon: She is a sadistic demon in the form of a beautiful young girl who feeds on negativity.
- First-Person Smartass: When she serves as the POV character in volume 2, Reines proves herself to be just as caustic (if not moreso) in her head as she is outside it.
- Friendless Background: Unsurprisingly, being an unrepentant asshole has not earned Reines many friends. This isn't a source of angst so much as some embarrassment, as it's one of the few things Waver gets to needle her about. Her arc throughout the series consists of her slowly getting friends like Gray and Olga, and admitting to herself that this is what they are to her without her pride getting in the way.
- Hime Cut: Although if you look closely her bangs seem to be slightly asymmetrical, so she can get that pinned-back bit. She's often referred to as a "princess", so it fits.
- Impoverished Patrician: The death of both Kayneth and his fiancée in Fuyuki has led to massive losses for the El-Mellois as they've taken a great hit to their reputation and accrued huge debts. With interest. The family's most valuable and precious item in the form of their magic crest is almost completely obliterated because of Kiritsugu and requires decades to fully repair. As such, Reines tasks Waver with taking on the responsibilities of safeguarding what's left, including the position of lordship in the Clock Tower, until she can properly take on the role.
- It Amused Me: It's clear that everything in life is a game to her and that she never bothers to take anyone seriously.
- Jerk with a Heart of Gold: Though she likes to provoke and bully others, she's also willing to cheer up Gray and remind her of her worth as a person and a friend.
- Lost in Translation: In all honesty her name should probably be spelled "Raineth", since her name in Japanese (ライネス) is almost identical to Kayneth (ケイネス). Reines came from a fan translation originally and grew so prominent among the fanbase that years later it became official when the anime released with official subtitles.
- Love Redeems: Her relationships with Waver and Gray gradually inch her out of Enfant Terrible territory.
- Magical Eye: Reines has Mystic Eyes which react to the presence of magic energy. Unfortunately for her, they do this by burning and thus function more like an allergy than a superpower. That said, as shown when she first met with Waver, she has some demonstrated capability of generating that fire for her own uses.
- Never Gets Drunk: It's noted in volume 4 that Reines has a downright insane tolerance for alcohol, with Waver noting that she often downs around ten glasses of wine—a potentially lethal amount for a girl her size—before going to parties and Gray recalling an incident where she annihilated half of Waver's department in a drinking game. Apparently, she considers it a power play.
- Nice Hat: She wears a small black bennet.
- Poke the Poodle: Even though she's mean to most people, she's actually nice to Gray. She only teases her in harmless ways like patting her on the head or embarrassing her with compliments. But Reines' narration claims that this is totally part of her usual sadistic behavior.
- Proper Tights with a Skirt: As fitting for a rich lady, she wears black tights with her dress.
- Properly Paranoid: Ate exclusively from military rations as the El-Melloi succession crisis was ongoing due to the high likelihood of getting poisoned. It's not unjustified considering just how ruthless magus culture is and the other murder attempts in the series.
- Sadist: By her own admission. She even appointed Waver to his position of El-Melloi II purely to make him miserable.
- Satanic Archetype: Because of her sadism, she's referred to as the Devil itself.
- Soft-Spoken Sadist: She has a calm and gentle voice to emphasize her sadism.
- Superpower Disability: Reines' Mystic Eyes tend to act more like magic hayfever than an actual ability, and she even has to take medication.
- The Tease: She jokingly proposes Waver to help her produce an heir when they're sharing a room together just to make him more uncomfortable than he already is.
- Tiny Tyrannical Girl: She practically rules over Waver's life and has him work like a slave for her own amusement.
- Token Evil Teammate: While most of Waver's students have managed to avoid falling into mage society's worst habits, Reines is happy to be a rat bastard even if she's technically on Waver's side.
- Troll: Reines's dickery isn't motivated by greed, or power, but rather because she's an absolute sucker for schadenfreude and loves making people angry, uncomfortable, and/or miserable.
- Troubling Unchildlike Behavior: When she was about eight, she was already a bit of a sadist, knew that you could kill someone by dangling them upside down long enough, understood concepts such as virginity, and wanted Waver to be her tutor so people would wonder about the implications of her being so close with her not-blood-related brother. You can kind of see visually that she's trying to fill the role of a grown adult at the age of eight — she has a special tall chair to put herself on an adult's eye level despite being practically pocket-sized. At fifteen, she occasionally drinks alcohol and can even handle "ten times" (supposedly) as much as it takes to make Waver (twice her age) pretty much horizontal. And her inappropriately sexual remarks have escalated to propositioning Waver to get her pregnant (much to his disgust).
- Tsurime Eyes: Her sharp eyes match perfectly her dominant and sadistic personality.

Originally Kayneth's Mystic Code, the Volumen Hydragyrum, it was... appropriated and reprogrammed by El-Melloi II and Reines (with unwanted assistance from Flat) to become something more suitable for their tastes and purposes.
- A.I. Is a Crapshoot:
- Flat interfered with its programming at the last minute by showing it The Terminator so it now occasionally goes on the rampage under the delusion that it was sent from the future by Skynet.
- Flat also went on to show it several more movies like Full Metal Jacket so its algorithm now randomly selects film quotes to comment on things, a trait Reines is annoyed with when in public.
- Combat Commentator: It activates a wrestling commentary mode the moment Luvia starts wrestling in episode 6, which Reines immediately assumes is Flat's work at play.
- Drop the Hammer: Its default combat mode is turning its hands into hammers.
- Meido: With the input of Waver, Reines used the Volumen Hydragyrum as the core for an all-purpose golem maid.
- Mundane Utility: It primarily uses its mercury body for cleaning the household.
- Slime Girl: Since it's made of mercury. Little ambient blobs of mercury tend to float around it, and it can even change forms, although it sticks to the "cute maid" look most of the time.
- Speaks in Shout-Outs: It rarely says more than a couple of words at a time except when it busts out the "I DIDN'T KNOW THEY STACKED SHIT THAT HIGH!"
- According to the glossary in the material book, Reines tolerates this because she learns other secrets via Flat's "magic hacking."
- Super-Powered Robot Meter Maids: Although its combat abilities mostly come up when it starts rampaging.
- Voluntary Shapeshifting: Later in the series, a small part of Trimmau gets split off for Waver to use for long-distance communication, with it manifesting as a tiny mercury Waver.

Simultaneously the brightest and dumbest student in El-Melloi II's class, Flat is an upbeat lad with a wide-eyed outlook on life. He frequently indulges in many of the same hobbies as his dear mentor, but his eccentricities tend to get on everyone's nerves.
- Achievements in Ignorance: Much of his magecraft can generally be described as simply doing something because he thought he could, even if for other mages, it would be extremely difficult, if not outright impossible.Touko: This isn't working off of any existing Foundations, is it? He's using the spell itself to serve as an impromptu Foundation. That's like inventing a new CPU for every spell he wants to cast. So he's one of those idiots who does ridiculous things just because he doesn't know they're supposed to be impossible.
- Ambiguous Disorder: No one's quite sure what's wrong with Flat, just that there is something seriously not right with him. His parents even entertained the idea that he might be a changeling and repeatedly tried to have him assassinated. There's also the implication that he doesn't value humans as humans. While he says that human lives are worth more than the Earth itself, he also says that it isn't efficient to sacrifice them for the sake of reaching the Root, rather than considering the moral implications of the deed.
- Ambiguous Innocence: While almost relentlessly sunny and cheerful, Flat occasionally shows a disconcerting Lack of Empathy that unnerves most people. As it turns out, he doesn't really have much empathy or conscience. However, a sense of love and Undying Loyalty towards Waver has led him to consciously adopt Waver's principles to make his own (somewhat janky) moral compass.
- Ambiguously Gay: When Svin asks him if he thinks Gray is cute in episode 0, he says he thinks Waver is cuter.
- Armor-Piercing Response: At one point, he receives a call from Gray on his cell phone. A furious Svin demands to know why he never gets calls from her, manhandling him into the ground. A nonplussed Flat just tells him that, to start with, it's because he doesn't have a cell phone.
- Badass Adorable: Bright-haired, blue-eyed, and relentlessly cheerful. His usage of magecraft is already first-rate despite his ditzy tendencies and he can easily bypass a dozen Bounded Fields and rewrite the wards of others without breaking a sweat.
- Because You Were Nice to Me: Well, not exactly nice, but Waver was the first person to treat Flat as human rather than a case study or possible existential threat to humanity.
- Boring, but Practical: His magecraft often has no visible effects, but does what he wants it to do, hinting at his obscene reserves of power.
- Canon Immigrant: Flat Escardos originally comes from Fate/strange fake, which itself started off as a cheeky April Fool's joke story that wound up becoming canonized and expanded upon.
- Cloud Cuckoolander: Flat is generally flighty, airheaded, and prone to Insane Troll Logic that makes the people around him question his sanity.
- Dark and Troubled Past: The combination of his talent and his personality has given him a lot of grief over the years. His parents treated him like a monster and repeatedly tried to have him assassinated. When that failed, they shipped him off to the Clock Tower in order to be rid of him. By the time he meets El-Melloi II, he has to fake smiles by using magecraft.
- Entropy and Chaos Magic: His specialty, as his elemental affinity is Ether.
- Everyone Has Standards: Even Flat, one of mage society's biggest deviants well outside the paradigm of what's considered normal, is shocked that Touko Aozaki would casually burn a sacred relic to render its ashes as usable only once for a spell.
- Expelled from Every Other School: Or rather "Dropped by every professor", but the connotations are the same.
- The Friend Nobody Likes: The one thing Flat does better than magecraft is getting on everyone's nerves, especially Svin and Waver's.
- The Gift: Flat was born with an innate understanding of magecraft and fantastic Magic Circuits to use it with. But his unusual temperament and ditziness squander his potential.
- Grade Skipper: While the Clock Tower is generally a secondary and post-secondary school, Flat was sent there at age nine. Ironically, he winds up Held Back in School, mostly because Waver's worried it's not safe (mainly for Flat, but also for anyone else) to release him into the world without supervision quite yet.
- Hair of Gold, Heart of Gold: He approaches life with childlike naivete and enthusiasm despite being almost twenty years old. He's always upbeat and cheerful, heaping praise on his friends (even if they don't like him for it).
- Hero of Another Story: Is one of the main protagonists in Fate/strange fake, which takes place in another timeline.
- Humanoid Abomination: It's regularly implied that there's something inherently wrong or alien about Flat's existence, and that he has more in common with the Lovecraft pantheon than other people. He's been the target of multiple assassination attempts by his own parents for this very reason, as they're convinced he'll become a threat of apocalyptic proportions if left unchecked. Ryohgo Narita, in an interview about Fate/strange fake, confirms that Flat's power and instability grows to the point that he has to be eliminated by either the Mages' Association or the Counter Force itself in every timeline where he doesn't meet El-Melloi II.
- I Always Wanted to Say That: Says this when surrounded by Gueldoa Davenant's monstrous thunder rabbits and telling Gray to make a break for it.Flat: This doesn't look good... I'll make a distraction, so you flee in the meantime, Gray!
Gray: But what about-
Flat: [beaming] I've always wanted to say something like that!
- Idiot Savant: Regularly regarded as one, as his talent and uncanny understanding of magecraft on an intuitive level are far beyond anyone's understanding, much less his own. He may be able to decipher the Voynich manuscript with ease, but good luck getting him to explain how he did it.
- Innocent Blue Eyes: His bright blue eyes emphasize his innocence and childish exuberance, but they also belie just how alien he is beneath the surface.
- Innocently Insensitive: Flat is not very good at recognizing when people are annoyed with him or why they are and will just keep on doing whatever it is that annoys or angers them no matter how much they tell him to knock it off.
- Iron Butt Monkey: He's often assaulted or manhandled by his professor and peers, taking it all with a cheerful grin. On the other hand, these people often abuse him so because of just how weird or annoying he's being.
- It Only Works Once: According to the Materials, Flat never uses the same spell formula twice. Whether this is "can't" or "won't" isn't clear.
- Keet: Exceedingly cheerful and talkative, which annoys everyone else on a regular basis.
- Kicked Upstairs: Normally, becoming Lord El-Melloi II's student is a great honor reserved for the best and brightest. Flat is only with him because literally no other teacher wants to deal with him.
- Mythology Gag: Echoes his own words from strange fake in episode 3, saying "Human lives are more important than the Earth".
- The Nicknamer: Is prone to giving everyone silly nicknames (especially El-Melloi II) like "Great Big Ben London Star" no matter how much they may protest them. It is mentioned that he believes if he uses the nicknames enough, they will be added to everyone's souls and make them more important.
- Parental Abandonment: Flat was sent to study at the Clock Tower at a much earlier age than most less because of his talent for magecraft and more because it was a convenient way for his parents to get rid of him without public embarrassment.
- Perpetual Smiler: He's always seen with a smile on his face even while in life-or-death situations.
- Pop-Cultured Badass: Like his teacher, Flat is up to date on pop culture and the use of electronics, chattering away with Caules about the latter's new PC and its specs.
- Precocious Crush: Seems to have one on Waver if his comments about finding him cuter than any of the girls are any indication.
- Squishy Wizard: For all his talent at magecraft, the main reason he can't graduate is because he keeps flunking his physical education classes.
- Teacher/Student Romance: He seems to have a (very, very) one-sided crush on Waver, whom he describes as "cute" and constantly fanboys. He tells Svin that he prefers looking at Waver over looking at Gray. (Waver, for his part, seems to see Flat as something between an adopted son and a huge thorn in his side.)
- Waistcoat of Style: Wears a blue-green one in contrast to his usual magenta in this story.
- Wrong Context Magic: Capable of performing ridiculously powerful and difficult magecraft with ease, but (or possibly because of) zero understanding of how he actually does it.
- Wrong Genre Savvy: Flat appears to have some vague awareness that he's in a detective series starring his professor. However, Flat being Flat, this primarily leads to bizarre conclusions such as that this means Waver must be a secret Baritsu master just like Sherlock Holmes.
- Youthful Freckles: Only in the manga, he's got some faint freckles, emphasizing how childlike and cute he is.

One of Waver's more prominent students in the Modern Magecraft Department.
- Animal Motif: Dogs, with his ability to sniff out things like a dog, his Beast magecraft giving him the aura of a dog, and he is frequently compared to one whenever he appears. Flat even gives him the nickname of "le chien" because of this.
- Bishōnen: Regularly noted to be such in the light novels' narration.
- Birds of a Feather: The main reason for his attraction to Gray is because he sees her as a kindred spirit, since both were the subjects of unethical magical experiments by their families to transform their natures.
- Cast from Sanity: Beast magecraft is very detrimental to the user's long-term mental health, eventually turning them into a wild animal trapped in a human body.
- The Dark Arts: As it's well-known to inevitably drive its practitioners insane, beast magecraft is an all but extinct tradition. Just about the only known family who still practices it is Svin's—not because they're uniquely resistant to its drawbacks, but because they figured any given family member going insane didn't really matter as long they could keep passing the Magic Crest on.
- Dark Is Not Evil: Shaggy, clad in dark blue, and easily riled up, Svin is nonetheless a sweet, awkward, and shy young man.
- Dogged Nice Guy: Towards Gray. Unlike most, however, he is rewarded with Waver ordering him to stay several feet away at all times instead of returned affections.
- No Sense of Personal Space: Svin tends to show affection for someone much like a dog would, which is part of why he's no longer allowed within five meters of Gray.
- The Nose Knows: Can pick up the scent of pretty much anything near him, even distinguishing between them by using distinct details.
- Not So Different: As much as Svin would like to believe he's the sensible one of the Flat-Svin duo, Gray is quick to point out that he's just as weird and responsible for nearly as many headaches as Flat.
- Perverted Sniffing: The particular behavior that got him banned from being within five meters of Gray.
- Straight Man and Wise Guy: Often appears together with Flat throughout the series, and Svin is the much more serious and restrained person of their duo.
- Super Speed: Easily catches up to a speeding car while using his magecraft.
- Surpassed the Teacher: During the series, Svin gets promoted to Pride, one of the ranks in the Clock Tower and a rank above Waver himself.note This ranking system is a separate system from the Lords of the Clock Tower though, so Waver still has that over Svin.
- Totally Not a Werewolf: Despite giving off an extremely werewolf-like vibe to the point that Flat invoked Werewolf Theme Naming immediately upon meeting him, Svin is simply a practitioner of Beast Magecraft rather than any sort of lycanthrope.
- Vitriolic Best Buds: He absolutely can't stand Flat (when they first met, Svin wanted Waver to kill Flat outright because he could sense how dangerous he could be), except he always ends up hanging out with him anyway.
- Werewolf Theme Naming: Invoked. While Svin's actual name doesn't have much to do with canines, Flat immediately dubs him le chien.
- Wolverine Claws: Gains these while using his magecraft, which are sharp enough to easily bust the tires and tear off the headlight of a speeding car.
- All Love Is Unrequited: Although Shirou did come to the Clock Tower with Rin, when Waver asks if they're a couple she denies it...but in a way that makes it clear she wishes they were.
- The Dreaded: Played for laughs. She's referred to as the "Red Devil" due to the problems she causes for Waver.
- Early-Bird Cameo: She was first mentioned in this series in the Material book, which came out a year before her in-story debut. It described her as the new cause of chaos in the classroom, now that Svin and Flat are separated after Svin's graduation.
- Experienced Protagonist: Like Waver, by the time she is introduced in this series she has already lived through a Holy Grail War.
- Hero of Another Story: Of course it should go without saying, but she was one of the three main heroines of Fate/stay night.
- Locked Out of the Loop: She had no idea that Gray resembles Saber, as Waver was careful to keep Gray out of the classroom whenever Rin had a class. Before the first volume of Adventures Rin and Gray had never even met, though Rin knew about her as the student she'd never gotten to see. When they do meet she freezes up upon seeing Gray's face.
- Big Eater: He gets hungry often.
- Cannibalism Superpower: As part of his creation he devoured the flesh of three gods to gain their factors. When Gray uses Altria's Magic Core, he also becomes hyperfixated on wanting to devour her.
- Character Title: He is the "man who devoured god" referred to in the title of the first volume of Adventures.
- I'm a Humanitarian: In the climax of volume 1 he tries to eat Gray after Wuzhiqi eggs him on.
- Like Brother and Sister: Gray starts to think of Ergo as a little brother over the course of volume 1.
- Line-of-Sight Name: Rin was the one who started calling him Ergo, as it was the only word he could remember when she found him. It comes from the phrase "Cogito, ergo sum" ("I think, therefore I am"), which is his magecraft incantation.
- Loss of Identity: Every time he uses the divine powers in his Phantom Hands part of his mind is vacated to make room for the 'information' of the gods within him. This is the cause of his amnesia. If he does this too much his personality will be completely overwritten by the gods, similar to Gray and Altria.
- Many Spirits Inside of One: Similar to Alter Ego Servants in Fate/Extra CCC and Fate/Grand Order, Ergo has the powers of multiple gods within him. The only one known so far, by both the cast and the audience, is Sun Wukong.
- Multi-Armed and Dangerous: He can project six Phantom Hands from his back. Each hand has a different power, and each pair comes from one of the Divine Spirits inside him.
- Omniglot: He learns languages at an incredible rate just from making conversation. When Rin first found Ergo he couldn't speak anything but in only half a day was speaking English, and by the time he meets Gray and Waver he can also speak Malay, Tamil, and Chinese. In addition his English initially had a Singaporean accent, but over the course of his conversation with Waver he started speaking in a proper British accent.

One of El-Melloi II's students.
- All Men Are Perverts: He says he set up his computer for "searching and database management", but from what we can see of it in the anime, at least one of the monitors is covered in porn and girls in swimsuits.
- Big, Screwed-Up Family: He doesn't look like he came from one, but Episode 8 has him share to Gray how, because of her sister's decision to leave the Forvedges for a normal life, members of their clan considered (and even attempted) to kill him to force her to stay.
- Capture and Replicate: It is eventually revealed that something of the sort happened to him during the Rail Zeppelin arc, in that the Caules we were supposedly following all along wasn't in fact him, but Dr. Heartless posing as him. It's not until Reines manages to barge into Rail Zeppelin together with the real him that the deception is finally revealed.
- For Want of a Nail: Due to the differences between the timeline of Fate/Apocrypha and Fate/stay night, the Yggdmillenia clan was never formed and Caules was made the head of the Forvedge family earlier due to his sister leaving to pursue a normal life.
- Hero of Another Story: Caules is one of the protagonists of Fate/Apocrypha, in which he was the master of Berserker of Black.
- Hormone-Addled Teenager: When Flat and Svin show up in his room to admire his computer it's plastered with pictures of girls in bikinis.
- The Medic: He can also use his electricity magecraft to heal wounds/injuries, as he tries to do for Waver after the latter got away from an assailant. This, however, leads to Waver figuring out that it's actually Heartless impersonating Caules, as it'd be impossible for the real Caules to be that good at it.
- Mission Control: Downplayed sort: among the students of Lord El-Melloi II, he's the one with the internet/data-savvy and a computer designed for such—which leads to him being tasked to corroborate news/data clues involved in his investigations.
- Mythology Gag: Has a poster in his room featuring a masked Frankenstein and Charles Babbage.
- One of his electrical spells is named Crafted Tree, a reference to Frankenstein's Noble Phantasm, Blasted Tree. It's even the same shade of yellow-green.
- Only Sane Man: Caules is mostly just a regular, somewhat lazy kid who somehow got dragged into "a class full of students dangerous in both talent and temperament" despite his protests. It is also implied this is the very reason Waver chose to bring him along during the Rail Zeppelin case (especially considering the grim stakes involved will just mean trouble for immature students like Flat and Svin).
- Shock and Awe: Is most skilled in electricity magecraft, a Mythology Gag toward his Servant in another timeline having electrical powers.
- Throw It In!: His talent in electricity magecraft. While Apocrypha had said he wasn't really cut out for the spiritual evocation that his family specializes in, it didn't say where his real talent was. So for Caules's appearance here Ryohgo Narita - the author of Fate/strange fake - suggested electricity as a nod to Frankenstein.
- You Are in Command Now: Due to his sister abdicating her position of clan head early on in this timeline Caules now has to take over as head himself.

Live actor: Kazuho Sō
A member of the Clock Tower's Policies Department, essentially a mage version of law enforcement. Tasked with maintaining order within mage society.
- Alike and Antithetical Adversaries: In many ways, she represents traditional magecraft's take on Truth that a magus simply makes reality happen the way they want. This is seen in her investigation style; put together the obvious evidence and motif and force the answer through. She recognizes that Waver is her idealogical opposite on this score.
- Animal Motifs: She's like a snake. She also uses a Mystic Code that looks like a snake.
- Boring, but Practical: Her Mystic Eyes have the ability to find lost items, which isn't very flashy compared to say Rider's Petrification or Shiki's Death Perception, but they get the job done and are very beneficial for her line of work.
- Connected All Along: It is eventually confirmed that Doctor Heartless is her brother, both adopted by the Norwich family, the original founders of the department of Modern Magecraft. It is later revealed in the final volume that they are in fact half-siblings. Curiously, however, her conflict with him has nothing to do with her personally, and purely incidental to her job as a Policies enforcer.
- Dragon Lady: To a T. It's implied she deliberately plays this up for intimidation, as Western mages tend to be quite ignorant about Eastern traditions and easily fall into Yellow Peril anxieties.
- Even the Girls Want Her: Gray's internal commentary acknowledges her as very beautiful.How many men would gladly offer up their souls just for that smile, I wondered. Her mysterious, oriental appearance would no doubt stir up interest from people of both genders.
- Faking the Dead: During the Adra Castle case, using a corpse that looked like her... at least after she'd gouged out the eyes. The anime renders this a Late-Arrival Spoiler.
- Hime Cut: With a kimono to match.
- Inspector Javert: She's the equivalent of this to Waver's Sherlock Holmes, although Word of God compares her to Irene Adler (sans the Dating Catwoman aspects she is often Flanderized into).
- Kimono Is Traditional: Subverted; though she may look the part, she doesn't abide by Japanese expectations or mage expectations. Indeed, the Policies Department is inherently heretical by mage standards, since they ignore the magus instinct to seek the Root, but rather focus on creating and maintaining stability in the Clock Tower.
- Magical Eye: She has Mystic Eyes with the power to find lost things. This helps her greatly in locating Trish's head.
- Meganekko: Subverted. She may have the glasses, but she's not a pleasant person.
- Motive = Conclusive Evidence: Basically the end-all be-all of how she solves crimes. It should be noted that this is how Waver also parses through mysteries, but he's much more thorough while Adashino latches on to what appears to be the most immediate and mundane possibilities at hand.
- Must Make Amends: When proven wrong, she'll admit her mistakes and do what she can to make up for it.
- Rapunzel Hair: Floor-length, even, as part of her desire to present herself as the image of a traditional Japanese lady.
- Red Herring: Adashino's antagonistic reputation and unscrupulous character makes it out to the audience that either she (or her acting on behalf of Policies) is the mastermind for all the mishaps experienced during the Rail Zeppelin auction. She is really not. It is later revealed that she, in concert with Waver, explicitly played it up to lure Dr. Heartless to finally reveal himself.
- Secret Police: The Policies Department is essentially mage society's answer to the KGB, with a reputation to match.
- Supernatural Is Purple: Has purple eyes and wears a purple obi.
- Worthy Opponent: Described as the Irene Adler to Waver's Sherlock, although it's also made explicit that the Promoted to Love Interest aspect of her that frequently shows up in adaptations is not present here.

Live actor: Nami Tamaki
The young head of the Edelfelt family, who crosses paths with Waver and Gray in the Castle of Separation case, leading her to become a student in Waver's Modern Magecraft class.
- Adaptational Comic Relief: Inverted. She usually plays comic relief as Rin's rival, but Case Files turns her into a more Rounded Character by showcasing her serious and even dangerous side to portray just how dysfunctional mage society can be.
- Adaptational Dye Job: Her hair and eyes are a paler yellow color in the anime in contrast to the more reddish hues she sports in other appearances such as the Unlimited Blade Works anime or unlimited codes.
- Ascended Extra: She only appears for the introductory case and the final arc in the books. In the anime, she takes a much more prominent supporting role as an acquaintance of the El-Mellois and she does some investigative work for Reines during the Rail Zeppelin arc.
- Curtains Match the Window: Golden hair and eyes.
- Dishing Out Dirt: Waver identifies her elemental affinity as Earth-based and thus her strongest attribute.
- Embarrassing Nickname: The Edelfelt family are notoriously known as "hyenas" for their viciousness and utter lack of scruples. Luvia would much rather be known as a "hunter".
- Fiction 500: Her reaction to being granted ownership of an upscale department store is to change the interior decorations to match her aesthetics.
- Kicking Ass in All Her Finery: An elegant aristocrat with no compunction about piledriving her enemies into the ground regardless of what she's wearing.
- Ms. Fanservice: Is seen lounging naked in a bathtub for one episode.
- Noblewoman's Laugh: Averted; Luvia here doesn't indulge in the laughter she's known for elsewhere in the Fate series. Fan speculation is that being around Rin brings it out of her.
- Ojou: She's head of the Edelfelt family, is possessed of significant wealth and prestige, and conducts herself accordingly.
- Polar Opposite Twins: She frequently makes allusions to her twin sister and it's implied they are a case of this. The material book reveals that Luvia is a popular extrovert who loves to get up in everyone's business with her travels while her sister is a shy introvert who is content to stay in Finland where she has a Perfectly Arranged Marriage set up. This even extends to their elemental alignment as her sister's alignment is Fire in contrast to Luvia's Earth alignment.
- Professional Wrestling: A fan and a practitioner, easily wrestling automatons to the ground thanks to her mastery of "Lancashire-style combat", which earns her the titles "Hunting Dog of the Ring" and "Forklift Lady".
- Regal Ringlets: Has her hair done up in large curls.
- Rich Bitch:
- Not above murder and assassination of people she doesn't like, such as the time she hired Flueger to kill Waver at the Castle of Adra since she saw him as a threat to her goals. Although she was also so impressed by him she later pushed for him to become her tutor.
- Her appearance in the sequel series The Adventures of Lord El-Melloi II includes her planning on using the time that Rin is away from London to steal Shirou away from her.
- Supernatural Gold Eyes: Indicating, among other things, her magic, her status and wealth, and her family's predatory associations.
- Wrestler in All of Us: One thing she very much does have in common with her other portrayals, combining her wrestling skills with her magic to take down enemies.
Voiced by: Miho Ohozaki (Japanese), Sarah Williams (English)
A Clock Tower student who belongs to both Waver's Modern Magecraft class and the Mineralogy department.
- Abhorrent Admirer: Waver finds her constant attempts to come onto him more irritating than anything else, telling her to jump out a window at one point.
- Chuunibyou: Dresses to stand out, and brags about her "AWESOME DEMON EYE!" and how famous she supposedly is for being so cool and powerful.
- Cute Little Fangs: It fits her energetic, trouble-making, quirky personality. They're sometimes even visible when she has her mouth closed.
- Eyepatch of Power: She wears a star-shaped eye patch to cover her right eye.
- Eye Scream: In the novels she changes her Mystic Eyes by way of physically plucking them in and out of her eyesocket.
- Gem Tissue: Her family's magecraft cuts gemstones and turns them into Mystic Eyes. Her right eye socket is used to plug in these gemstone eyes, with one that lets her see human emotion, one that lets her see leylines, one that lets her cast runes to activate fire magic, etc.
- Girlish Pigtails: As part of her chuunibyou look.
- Hazy Feel Turn: She was working with Dr. Heartless for most of the Rail Zeppelin arc as he promised her incredibly rare Mystic Eyes in exchange for her assistance. After Waver reveals this to his audience, she gives up the ghost and admits to everything. However, she won't give up her laser-focused aim at obtaining Mystic Eyes that led her to allying with Heartless in the first place.
- Living Lie Detector: Of sorts. If what she says is true, she can use her Mystic Eye of Viewing Emotions to see how someone is really feeling.
- The Mole: Straight-up admits that she's in Waver's classroom as a spy for the Neutral Faction of the Magus Association's political three-way. It's also revealed at the end of the Rail Zeppelin arc that she was secretly feeding Dr. Heartless info about Caules to help him.
- Nice Hat: Has a mini-hat perched on the right-hand side of her head.
- Playing with Fire: One of her Mystic Eyes can set fire to anything she aims it at. It's implied that it's less an inherent power of the eye, and more it casting Instant Runes that summon fire magic.
- Stalker with a Crush: She is, in her own words, the number one expert in breaking into Waver's bedroom.
- Teacher/Student Romance: She would like to have one with Waver, as she's one of the students besotted with him and wishes to eventually become his mistress, but her professor isn't going to reciprocate any time soon.
- Yaoi Fangirl: Mentions being into BL after assuming Waver and Caules are together in that way on the Rail Zeppelin.
- You Gotta Have Blue Hair: One of the few characters to have an explicitly outlandish hair color in the form of bright pink and purple.
Voiced by: Miyuki Ichijou
Hailing from one of the Mage's Association's Three Great Families, she is Lord of the Creation department and one of the major leaders of the democratic faction.
- As Long as It Sounds Foreign: Good luck finding someone with anything resembling her name in real life.
- Cool Old Lady: Unlike most magi, she's willing to use modern tech, including an iPod she uses to listen to rock music. Her reasoning, befitting her role as Lord of the Creation department, is that true art is whatever moves the hearts of the people of the present.
- Dishing Out Dirt: An expert at sand magic due to her triple affinities in Wind, Earth, and Water.
- The Mentor: She was one of Touko's teachers at the Clock Tower, and Touko genuinely does respect Inorai as both a mage and person.
- Ore Onna: She uses the masculine pronoun "ore". In the scene where she (and her speech pattern) is first introduced, she's knocking back glasses of whiskey in a single gulp. A bit of a tough old broad.
- Red Baron: Known for the nickname of "the Amazon of the Clock Tower".
- Spell My Name with an "S": She is ever so briefly mentioned in Grand Order's crossover event with Fate/Zero, in which the official translation of the game spells her name Valuayeta. The anime subtitles spell her name Valueleta, which (as with Reines as discussed above) started as a fan translation that grew popular and so got picked up by Aniplex's translators.
Voiced by: Daisuke Hirakawa (Japanese), Christian La Monte (English)
An old semi-friend of Waver's from the Clock Tower.
- Adaptational Attractiveness: A lot more benign-looking in the anime, whereas the novel illustrations tend to give him the Face of a White-Haired Prettyboy.
- Ambiguously Bi: After making his entrance on Rail Zeppelin, he fondly strokes Wavers forehead as the latter sleeps. Although at one point in the anime, and more prominently the novels, he seems to have a bit of a thing for foreign women, so he might swing both ways.
- Badass Biker: Is a capable motorist, to the point that Waver trusts him enough to outrace evil spirits and drive themselves out of an underground mining facility.
- Big Bad Wannabe: He likens himself to being both Waver's primary sponsor and a major source of his miseries as the various plights the latter experiences during his adventures wouldn't have been possible without the proper funding.
- Biseinen: One of the few guys who gets an almost-equal level of appearance-related gushing in Gray's narration as the girls get.
- Color Contrast: With Waver. Melvin's hair is silver, Waver's is dark. Melvin's eyes are purple, Waver's are green. Melvin has a pale complexion, Waver's is darker. Also, like Waver, he tends to wear scarves and ties◊, but he wears a white scarf while Waver's are red or gold.
- Disappeared Dad: According to bonus material in the artbook, his father abandoned him because he's too weak to be a mage and only his mother stuck by him. Then his father came back when it turned out little Melvin was actually spectacularly talented as a Tuner of others' crests and circuits, although this taught Melvin some painful lessons about his value in the eyes of others.
- Disease Bleach: He and Waver are around the same age, and he's had silver hair for as long as they've known each other. However in contrast to characters like Gray and Olga Marie, it appears to be due to a more mundane cause such as illness or albinism as opposed to a sign of magical power, and in fact he's a rather poor magus for the most part.
- Dream-Crushing Handicap: Due to his weak constitution, he's "hindered from becoming a mage". This parallels Waver's lack of talent as a mage.
- Eccentric Millionaire: At one remove around the time of Zero; his mother's wealth let him offer money for an interesting story, so Waver got him to lend him the money he needed to get to Japan. He later lent Waver more money to buy the El-Melloi class because he felt they were friends.
- First-Name Basis: How he addresses Waver. He explains to Gray that he's continued doing this even after Waver became Lord El-Melloi II because it'd be lonely for Waver if no-one called him that when he eventually relinquishes his title.
- Like Waver, he is a Mage with a very specific niche that's based on enhancing the abilities of others. Unlike Waver, he has no complex about his lack of personal power and is almost too eager to live vicariously through those he sponsors through either his magecraft or his money. Furthering the parallels is the color contrast between the two and the fact that unlike Waver his magic circuits are said to be of decent quality, he's just too infirm to use them properly.
- Like Kotomine, one of Waver's previous enemies, he's a big Troll and depraved hedonist who enjoys the misery of others. But unlike Kotomine he doesn't deliberately perform cruel acts or take pleasure in inflicting suffering himself. Rather, he prefers to passively enable others for his own amusement.
- Handsome Lech: He babbles about getting laid more than enough (but the closest thing we see to him trying to put the moves on anyone is just a very sweet, earnest offer to be Waver's best friend, while clutching Waver's hands and blushing).
- Ill Boy: Suffers from an unspecified condition that causes him to vomit blood and hinders him from becoming a Mage. He also appears to have clinical albinism (as opposed to just being a more typical white haired anime boy), as evidenced from the lack of pigment even in his eyelashes, and is described as such in the light novels.
- Interclass Friendship: With Waver.
- It Amused Me: In Melvin's case, it's not that he does things because they amuse him, but instead that he goes all out to watch amusing things. In his own words, he's a brute who takes pleasure in watching the corruption or fall from grace of others, and a brute has dignity in being what they are - if it seems fun, he must see it through to the end, no matter what it costs him, or become a coward.
- Magic Music: Uses his violin as part of his magecraft, temporarily enhancing others' Magic Circuits.
- Meal Ticket: Melvin is happy to loan Waver any sum of money without even the expectation of being paid back... as long as Waver's willing to be his "best friend," that is (a proposal he made while holding his hand and blushing).
- Momma's Boy: In the light novels, he mentions his "mummy" so many times within a few minutes of meeting Gray that she starts wondering if he has an Oedipus Complex. To be fair, he just escaped a helicopter crash, so it's kind of understandable he'd be whining about wanting his mommy to take care of him.
- Screw the Rules, I Have Money!: Rail Zeppelin is very secretive and you can really only get on it if they invite you. When he discovered Waver and his students were on it (and he wasn't told by Reines), Melvin, for some reason, managed to get himself invited in. Admittedly, he doesn't credit it to himself solely, but to his family's influence. He repeatedly uses this financial influence to get the auctioneers to delay as much as possible for Waver's preparations.
- Slasher Smile: Official artwork for the novel tends to feature him with a sinister expression despite his being on the side of the heroes.
- Spell My Name with an "S": His surname is translated as "Weins" in the official anime translation as opposed to the fan translations of Waynes or Waynez.
- Supernatural Is Purple: He's a mage, and has pale blue eyes which look light purple in the anime.
- White Hair, Black Heart: Subverted, as illustrators like to make him cut a very sinister image◊ as an albino, Gray is immediately suspicious of his intentions, and even he describes himself as a brute, among other Obviously Evil traits, but he remains a loyal friend and his actual actions are amoral at the very worst.

A mercenary and necromancer from Japan. He shows up at the Marsburry Workshop to pay his respects to Trevor Pelham Codrington, an old friend of his.
- Abnormal Ammo: He fires bullets made with human fingers and throws grenades made of human hearts packed with teeth.
- Bruiser with a Soft Center: A little bit. He seems to quickly warm up to Gray, and expresses concern for Waver when he realizes he and Waver have similar dead-loved-one issues. Plus, he pauses to get sentimental over a children's book of fairy stories.
- Canon Immigrant: Although he's an existing Nasuverse character, Kairi's role in this series is entirely anime-original, and he never appeared in the light novels.
- Casual Danger Dialogue: While holding off a pack of monstrous fae hounds, he calmly banters with the rest of the group... and asks Waver whom he should send his invoice to.
- Cool Shades: Ones that he never takes off, even indoors.
- For Want of a Nail: He's still doing freelance mercenary work, as he wasn't chosen as one of the Association's representatives for the Great Holy Grail War.
- Hell-Bent for Leather: He looks like he stepped out of a biker gang convention.
- Hero of Another Story: Like Caules, he originates from Fate/Apocrypha and was one of its protagonists.
- Hunk: Burly, bearded, and manly.
- Mage Marksman: He's a magus whose primary weapon is a shotgun packed with human fingers.
- Magitek: His shotgun is treated with several rituals in order to use his magecraft.
- Necromancer: A skilled and famous one who appropriates human corpses to use as ammunition in battle. He also participates in the ritual that gets to the bottom of the incident at the workshop.
- Only in It for the Money: Well, he is a Bounty Hunter. But when Waver gets visibly alarmed at being asked for money he doesn't have, Sisigou asks for just one cigar as payment. This might also have to do with a theory he voices in Fate/Apocrypha:You can trust someone who works for money, so long as you have money. But when you work for free, people get scared what if he comes back for what hes owed?
- Outliving One's Offspring: His (adopted) daughter. He only briefly alludes to her here while talking to Gray about fairy tales, but in Fate/Apocrypha where Kairi is a main character, she's the core of his motivation.
- Spell My Name with an "S": In the official anime translation, his family name is transliterated as it would usually be, "Shishigou", rather than "Sisigou", as it was transliterated for Fate/Apocrypha.
- Sunglasses at Night: Always wears them, even when he's in a dark catacomb, wearing a light clipped to his sweater so he can see because it's so dark. The sunglasses stay on anyway, because he always wears them.

Daughter of Marisbury Animusphere, the Clock Tower's Lord of Astromancy, who meets Waver while serving as her father's agent on the Rail Zeppelin.
- Age Lift: She is much younger compared to her F/GO counterpart due to the 12-year difference in the timeframe.
- As Long as It Sounds Foreign: Olgamarie or Olga Marie are both fairly normal if slightly archaic Scandinavian names, but her last names are really out there.
- Classy Cravat: A female example.
- Death from Above: She conjures a meteor shower to attack the Child of Einnashe at the end of Rail Zeppelin.
- For Want of a Nail: Her father's not taking part in the Grail War, so there's not going to be a Chaldea for her to join.
- Foreshadowing: In-franchise, the reveal of her meteor shower magecraft, Anima Animusphere (implied to be a family specialty) predates the later reveal of the more extensive powers of her father's Alternate Universe heir, Kirschtaria Wodime of Fate/Grand Order.
- Green-Eyed Monster: She hates people who are recognized for their efforts, or who think they don't have to be recognized by others, spawned by her own need for recognition.
- Harmful to Minors: She stumbled upon her tutor's headless body, followed shortly after by her missing head, and she was 11 at the time.
- Hero of Another Story: Averted, unlike many of the other guest characters in the series. While Olga originates from Fate/Grand Order and was heavily advertised as a main character before its release, she dies right at the start of the story. Though she comes back years later in Lostbelt 5 as a villain in the form of the Alien God/Beast VII.
- Idiot Hair: Has a large ahoge on top of her head.
- Mystical White Hair: Has silvery hair and is a talented aristocratic magus.
- Ojou: As the daughter of one of the Lords of the Clock Tower.
- Parental Abandonment: According to Trisha, her father abandoned her after researching the Greater Grail. Her mother has never been mentioned.
- Spell My Name with an "S": Not her, but her father; the anime subtitles use the direct transliteration from Japanese, "Maris Billy", rather than the translation from the Grand Order game, "Marisbury". The English dub goes with Marisbury.
- Supernatural Gold Eyes: Being a mage.
- Tsundere: She's somewhat more reasonable than in Fate/Grand Order, but even so she makes a show of chewing out Gray for not being prepared when Waver gets injured, then offers her Panacea to help with Waver's healing, then waves off Gray's thanks by declaring Animusphere has discharged its debt to El-Melloi and that's the end of it. In episode 13, she is later seen sneaking into El-Melloi and Gray's hospital with a bouquet of flowers.
- Younger Than They Look: She's only 11 years old in this series but looks a couple of years older than that.
Voiced by: Kumiko HigaOlga Marie's tutor. Her family is part of an offshoot branch of the Animuspheres.
- Bag of Holding: Because her elemental affinity is Hollow, Trisha can access Imaginary Number Space to hold objects in miniature pocket dimensions. The only other known mages with this affinity are Lev Lainur Flauros and Sakura Matou.
- Early-Bird Cameo: Trisha makes a brief cameo in episode 2 as the person who hired the El-Melloi faction to take on that episode's case.
- Off with Her Head!: How she was killed.
- Prim and Proper Bun: Wears her hair in a tight bun as befitting her role as Olga's tutor and caretaker.

A member of the Holy Church. He attended the Mystic Eyes auction aboard Rail Zeppelin not to buy Mystic Eyes, but to get rid of the ones he was born with.
- Badass Preacher: Another in a long line of battle-ready priests in the Nasuverse.
- Blessed with Suck: He doesn't like his Mystic Eyes and so boarded Rail Zeppelin to get rid of them.
- Brainwashed and Crazy: He was used as a puppet by Dr. Heartless to carry out serial killings. And he's not happy about it when he finds out.
- Even Knight Templars Have Standards: When asked why he's helping Olga, he comments that while he does think Mages will go to hell, he's not going to kill a little girl while she's crying about the death of her best friend.
- Eye Scream: The removal of his Mystic Eyes involves the actual removal of his eyes while he's conscious.
- Fantastic Racism: The Church dislikes Mages, and Karabo is no exception.
- Gentle Giant: Downplayed in that he's not a pacifist or anything, but he's still a kind and respectful old man despite his gruff appearance.
- Heroic Sacrifice: Takes a blow for Gray to protect her from Faker which kills him.
- Noble Bigot: Despite his problems with Mages and belief that they will all suffer in Purgatory, he stands aside and allows Olga to mourn Trisha's death because that's a completely unrelated issue. And although he's a Christian he spends his final moments reassuring Gray to trust in the power of her lance as people would pray in the old days.
- Old Soldier: His wrinkles and white hair betray his age, but he's strong enough to hold off a Servant for a decent amount of time. He's an old soldier of the Holy Church after all.
- Punch-Clock Villain: As a priest of the Holy Church he's a mortal enemy to all Mages, yet during his time aboard Rail Zeppelin he's very polite and courteous, never antagonizes anyone, and willingly works with everyone in solving Trisha's murder, freeing the train from the 'Child Of Einnashe,' and fighting againt Faker to the point of a Heroic Sacrifice.
- Seers: Karabo's Mystic Eyes allow him to see the past, though they can't be controlled, such as when he unwillingly sees Gray's after brushing against her and then promptly apologizes for invading her privacy. He can also bring in "echoes" or "recordings" of things he has seen in the past into the present. For example, if he sees a knife cut through the air, then at a later time in that same location he can bring that cut into the present so it cuts through whatever is there.
- Spell My Name with an "S": Some fans romanized his first name as the wildly different (but not necessarily inaccurate) "Callebaut", but the official anime subtitles go with Karabo, which has the benefit of being a proper name in Africa.
- Spellblade: Following from Ciel and Kirei, he fights with Black Keys. Unlike how Kirei mostly used his as Wolverine Claws, Karabo's preferred method seems to be Throwing Your Sword Always Works like Ciel.
Voiced by: Kanehira YamamotoA magus who happens to be the star of a zombie-themed cooking show.
- Demoted to Extra: He was actually one of the guests aboard the Rail Zeppelin in the novels, albeit not a major player in the case. The anime removed him from the train and reduced him to one scene on the set of his show, where he provided his information to Luvia and Kairi instead of to the main characters.
- Hunter of Monsters: Plays one on his cooking show, where he shoots at actors pretending to be zombies.
- Knowledge Broker: Is very media-savvy for a magus, and thus able to obtain all kinds of useful information others might not notice. For example, the identity of Dr. Heartless.
- Pest Controller: He specializes in using spider familiars.
- Spell My Name with an "S": His last name is spelled by the official translations as "Supinerra" instead of "Spinella" or "Spinerra".
- The Spymaster: Relies on a web of spider familiars to obtain his information.
- Supreme Chef: The fact that Luvia would compliment his cooking, speaks volumes of his skills.

- Arab Oil Sheikh: Part Middle-Eastern, and his wealth has made him known as the "Oil King".
- Canon Immigrant: He was created for the anime adaptation of Unlimited Blade Works, but his inclusion here, coupled with Nasu's statement that Case Files is in the exact same world as Stay Night instead of an alternate timeline or even Broad Strokes, means he is now canon to the original visual novel.
- Dead Man Writing: The final story arc of the novels happens after Caster kills him, but he still shows up in this manner to help Waver out.
- Irony: It's implied his original intent was to summon Siegfried, as he has his catalyst of a linden leaf. Touko burns it for ashes as a spell reagent. Unlike Medea, Siegfried is ceaselessly loyal and does not talk back to his master, meaning things could have gone very differently for Atrum otherwise.
- Screw the Rules, I Have Money!: While a decent mage in his own right, most of his great prestige was achieved through buying his way up, including his participation in the Fifth Grail War.
- Spell My Name with an "S": The fan translation of the novels spell his name Atram, while the official translations of the anime (both Case Files and Unlimited Blade Works) spell it Atrum.
- Weather Manipulation: Atrum's expertise in magecraft is described as such.
- For Want of a Nail: Because this takes place in the Fate multiverse, Zepia does not become TATARI as he was in Melty Blood, and remains the head of the Atlas Institute.
- Abusive Mom: Magdalena willingly offered Gray as a sacrifice to be used as the living vessel for Altria's reincarnation. As it turned out, it was a double subversion; Magdalena fought to prevent Gray from being taken over by Altria, but had to pretend she was even more fervent than the other villagers, even if it meant Gray hated her. Since Gray didn't know what Magdalena was up to, believing she'd become just like the others, it had the same effect as if Magdalena had meant it, isolating Gray and contributing to her issues with her face.
- Feminine Women Can Cook: According to Gray's Valentine's scene in Grand Order, Magdalena used to make her fudge, before her face changed. Gray says that Magdalena claimed it was the only thing she was good at.
- Only One Name: 'Magdalena' is the only name she's known by, much like Gray.
- Author Appeal: Has freckles and full lips due to the author being a fan of those features.
- Bare-Fisted Monk: Prefers punching enemies with the standard Church weapon; the Ash Lock, a gauntlet made from Biblical scripture for the express purpose of punching anyone who blasphemes against the Lord.
- Knight Templar: Rather enjoys having the ability to punish those who do not follow the teachings of the Lord.
- Lipstick Lesbian: Attracted to arrogant girls like Reines.
- Named After Somebody Famous: His family took on the name of the Dead Apostle Gransurg Blackmore after he died 1,700 years ago, out of respect.
- Ascended Extra: He was first briefly alluded to in Zero, though he didn't even have a name back then.
- Necromancy: Befitting the Lord of Spiritual Evocation. His many rings and his necklace contain ghosts to use for both power and knowledge, and he can summon various forms of undead.
- Spell My Name with an "S": His first name is also spelled Rulfurus in some translations.
- Large and in Charge: He is very tall and broad-shouldered.
- Spell My Name with an "S": His first name is also spelled McDonell by some translations.

A rogue magus looking to use the tomb of Alexander the Great to achieve renown as a magus.
- Con Man: Got as far as he did by tricking lots of people into coming to Babylon with various excuses.
- Desecrating the Dead: Barzan's goal is to break into Alexander the Great's tomb using slave labor to raze it for relics.
- Foil: Like Waver he's a mediocre magus who left the Clock Tower looking for fame and acknowledgement, and aims to achieve it with the help of Alexander the Great. But he lacks Waver's strong morals or post-Character Development humility, gleefully takes advantage of others instead of relying on his own efforts, and treats Alexander's legacy as something to exploit instead of respect, which are what put him in conflict with Waver.
- Gory Discretion Shot: The last shot we see of him is right before a group of evil spirits converge upon him.
- Magic Eye: Has the basic Mystic Eye ability to immobilize people with his eyes.
- Small Name, Big Ego: Dropped out because he felt the Clock Tower didn't appreciate his talents enough, but Waver figures it's because he's a pretty crappy magus to begin with.

- Facial Profiling: Implied to be Asian, and is drawn with Eyes Always Shut.
- Multi-Ethnic Name: Has a Spanish/Portuguese first name and a Chinese surname.
- Necromancer: His magic specialty. It's likely these skills were used by Ernest to manipulate his body parts in the right configuration for his experiment.
- Red Herring: He's seen peeking, suggesting he's up to something. In the end it turns out that he had no direct involvement with Ernest's death, though it's possible that Fernando contributed some of his necromancy research in order for Ernest to perform his ritual.
Voiced by: Mao IchimichiServant of the Fargo family.
- Ambiguously Gay: Is seen holding hands with Mary at the end of Episode 2.

- Offing the Offspring: Attempted to consume his daughter Mary as a ghost to achieve full immortality.
- Star Power: As a branch member of the Animusphere family his magical specialty is in Astromancy, and the design of his family mansion is designed to reflect the heavens. The mystery of his murder is centered around the positioning of his organs in alignment with the classical planets (i.e., including the Sun and Moon, and excluding Uranus and Neptune).
- Suicide, Not Murder: Waver quickly deduces that the culprit of the murder of Ernest Fargo is none other than the man himself. By dismembering himself and arranging his body parts in accordance with the orbits of the planets Ernest became a revenant in the hopes of attaining immortality.
Voiced by: Yutaka AoyamaA member of the Zoology department competing for a vacant position after one of its members is assassinated.
- Blue-and-Orange Morality: Demonstrates the typical magus viewpoint of believing human lives are worth nothing other than as fuel to reach the Root. And he's ultimately arrested for threatening to break the Masquerade rather than for all the lives he's claimed.
- Born in the Wrong Century: Waver points out that a hundred years ago Davenant might've just been an ordinary mage, but modern technology has made his actions far too obvious, and far too easy for muggles to discover.
- Familiars: As expected from a specialist in Zoology, he has the ability to summon monstrous spectral rabbits to consume electricity and attack people.
- Fiction 500: Former owner of Carnac, which is this universe's equivalent of Harrods.
- Shock and Awe: Most of his magic spells involves the use of lighting magecraft in accordance with the imagery of Zeus.
- Spell My Name with an "S": The official subtitles use "Gueldoa" but onscreen text spells it "Gurdoa".

Voiced by: Tomoaki Maeno (Japanese), Ben Lepley (English)An instructor at the Department of Spiritual Invocation who calls for Waver's help in finding the true culprit for the death of his father Trevor.
- Abusive Parents: His father forced Fairy-type Mystic Eyes upon him then exploited them in order to create the Black Dogs.
- Ascend to a Higher Plane of Existence: Notes that going to the fairy realm is not the same as dying.
- Biseinen: Fair-featured and known in-universe for his good looks.
- Chick Magnet: Is introduced with a female student professing her love for him before he firmly rejects her, and Waver mentions his popularity with the womenfolk.
- Foil: To Waver. Both are young and handsome teachers at the Clock Tower who persistently spurn the affections of the numerous female students who come onto them, and in both cases, it's due to a preexisting obsession with a figure from their past who is currently beyond their reach (Faye/Iskandar). But whereas Wills ultimately chooses to leave the world of the living for the fairy realm with Faye, Waver learning to give up on his dream of reuniting with Iskandar to live for his sake is a major component of his character development.
- Heroic Sacrifice: Rather than blind himself or wait for the Mage's Association to dismantle the portal that causes Black Dogs to run amok, Wills decides to cross into the fairy realm with Faye.
- Love Makes You Crazy: Kairi notes that his eagerness to follow Faye into the fairy realm may be partially provoked by his Mystic Eyes.
- Magical Eye: Can see fairies due to his "Fairy"-type Mystic Eyes. The fact that he was not born with them like he claimed he was is what ultimately kicks off the Myth Arc.
- Necromancer: His family's specialty in magecraft is Necromancy, and he attempts to make contact with the spirits of his father and Waletta to solve the case.
- Single-Target Sexuality: Rejects all of his suitors because he's already in love with the fairy Faye.
- Spontaneous Weapon Creation: Can create reinforced knives from thin air with magic invocations of Old English.
- Suspiciously Similar Substitute: Is at least partially derived from the books-specific character Heine Istari, whose storyline was not adapted into the anime. His character design is almost identical, he's skilled in magic-based martial arts, and does not survive the events of his arc.
Voiced by: Fuyuhana OnoA member of the main Codrington family and the one to accuse Wills of murdering his father.
- Ascend to a Higher Plane of Existence: Wills mentions that rather than reaching Heaven or Hell, the spirit of Waletta was transformed into a fairy, and that she is waiting for him on the other side of the portal along with his father.
- Bolt of Divine Retribution: Is attacked and killed by the Black Dogs responsible for the lightning storms at Marburry Manor.
- Dark-Skinned Redhead: Has dark skin and red hair, and is quite aggressive.
- Woman Scorned: Was Childhood Friends with Wills until he rejected her marriage proposal and earned her enmity.
Voiced by: Yo Taichi (Japanese), Morgan Berry (English)
- Alleged Lookalikes: Deconstructed. Not resembling Iskandar or Hephaestion all that much was crucial for her role as a malefic spell scapegoat.
- Berserk Button: Nothing much ruffles her in combat personally. However, ever implying/claiming that you understand Iskandar's motives and actions (and by extension, those of his followers plus her) is a good way to get her gunning for your throat.
- Body Double: Her role in life was to be this for Iskandar. His underlings spread false information about his appearance so curses directed towards "Iskandar" hit her instead, allowing the King of Conquerors to operate unimpeded. This is used to explain why history recorded Alexander the Great as thin and with heterochromia while Fate's Iskandar is a giant of a man.
- Dark Action Girl: She's the primary physical combatant among the villains, and invokes the name of Hecate for her Noble Phantasm.
- Dead Person Impersonation: When she first appears she introduces herself as Hephaestion, but she's actually his sister. She wasn't part of the Ionioi Hetairoi in Zero and so Waver doesn't recognize her because of that, which is a clue that she's not who she says she is.
- The Dragon: To Dr. Heartless, since she serves as his Servant during the events of the Light Novels.
- Evil Counterpart:
- To Iskandar. She dresses in clothes very similar to his,note her lightning is red to contrast his blue lightning, and her chariot Hecatic Wheel is almost identical to Iskandar's Gordius Wheel with the only difference being it's pulled by skeletal wyverns instead of divine bulls.
- To Gray. Both serve the role of pseudo-Servants to their respective masters Dr. Heartless and Waver, acting as the muscle for their respective sides, and both were born for the sole purpose of supporting a powerful king (in Faker's case by acting as a Body Double for Iskandar, in Gray's case by being a vessel for Altria's soul to possess).
- When her personal sentiments are ultimately revealed, i.e. she laments and finds Iskandar's dream regrettable, she unwittingly serves as one to Zero-era Saber/Altria, whose main motivation was to redo/reject her actions as King Arthur.
- History Repeats: She also charge head first into the Wave-Motion Gun attack from a Saberface, just like Iskandar did in Fate/Zero and survives the attack just like he did, albeit without sacrificing her chariot as her master teleported them out of the way at the last minute, unlike with Iskandar.
- Honor Before Reason: She rescues her opponent Gray from an avalanche, saying, "Warriors should only die on the battlefield."
- Magic Knight: Faker would much prefer to match swords with her opponents, but Olympia, Iskandar's mother and her teacher made sure she was equipped for a duel between mages too. In fact, Faker was taught ancient Greek magic deprived from the Goddess Hecate. This training and worship endowed her with the skill, High-Speed Divine Words. Faker's mastery is such that her skill is rank B, the same as Circe, the Queen of Greek Witches! Just as Medea and Circe, Faker can conjure forth grand-rituals and maelstrom of magics with just a single word.
- Magical Eye: She possesses Mystic Eyes of Compulsion (which make her eyes glow orange), allowing her to control someone's body. During her first encounter with Gray and Waver she forces Gray to attack him against her will. It also makes an effective and painful interrogation tool as Gray had the displeasure to find out after accidentally taking a peek in Faker's memories.
- Mismatched Eyes: It is really subtle, but her eyes are actually different colors (one appearing to be very pale gold, almost grey, while the other is blue). This matches up with accounts that Alexander the Great had heterochromia.
- Muscles Are Meaningless: Her strength stat is rank B, which means she's actually as physically strong as her king, the musclebound Iskandar! The only clue that could even remotely alert you of this fact is her clothes.
- Never Given a Name: After her true identity is revealed, she reveals that she was born without a name. Being Iskandar's double was her entire purpose in life to the point that when Iskandar tried to give her a name (multiple times mind you), she vehemently refused.
- Older Is Better: She could easily overpower Touko, one of the greatest magus in the modern era, in a contest of magecraft since Faker wield Age of Gods mystics.
- One Degree of Separation: She's and by extension, her teacher Olympia, an adept and worshipper of Hecate, Greek Goddess of the Moon and Magics. The Goddess Hecate was of course, the personal teacher of Medea and Circe, two of the most well known and powerful witches in Greek Mythology and prominent servants in other Fate titles.
- The information on her Noble Phantasm also implies it either draws its power from or actually is the chariot given to Medea by Helios after princess-turned-witch murdered her children in revenge for Jason abandoning her.
- Pretender Diss: She mocks Waver as being too weak and average to be one of Iskandar's followers. He eventually retorts that since he didn't see her in Ionioi Hetairoi, she isn't one of his followers either.
- Shock and Awe: Red lightning accompanies her and her Noble Phantasm, in contrast to Iskandar's blue.
- Sour Supporter: Being supposedly Hephaestion, you would expect her to be at least among the Ionioi Hetairoi Noble Phantasm of Iskandar, or at the very least share his Tragic Dream. By episode 9, Gray was already having visions of her explicitly rejecting and belittling Iskandar's ultimate vision. This is ultimately explained away by her being revealed not to be Hephaestion, having more of a link to Iskandar's mother (who, as history records, is his Arch-Enemy), and working for a Master who will probably never be approved of by Iskandar in the first place. Being ultimately revealed as Iskandar's Body Double, i.e. someone who had to bear the risks/dangers of his position without the glory/honor camaraderie of it, it helps to explain why she might be bitter/finding it ultimately hollow.
- Taking the Bullet: She's so used to doing this in life when she acted as Iskandar's malefic spell-scrapgoat that it's now one of her skills. Her personal skill, "Blessing of the Nameless", allows her to take damage in place of the one she sworn her alliegance to. Whether it's by sword or spell, she will suffer in her master's place and with the right preparations, even reduce the damage taken.
- Tyke Bomb: For all intent and purpose, Faker was essentially raised this way by Iskandar's mother, Olympias.
- Variant Power Copying: Her skill, "For He is Another Iskandar (False)", allows her to copy all of her king's abilities, albeit with all the copied abilities suffering a reduction in rank. However, she can modify her copied abilities to better suit her needs. This skill stems from her entire life living as Iskandar's body-double.
- Worthy Opponent: Comes to see Gray as one since she's one of the few people in the modern world who can put up a fight against her. To the point that she decides to save her life during a snowstorm so she can fight her on a battlefield once again.

- The Ace: One of the most powerful mages in the setting, with multiple backgrounds in the Clock Tower's varies department of studies, making him a very versatile mage. Having come in contact with faeries and subsequently having his heart stolen has also added true Mystery/Mysticism to his existence, making him more than human now, allowing Dr. Heartless to use a degree of power unseen since the Age of Gods.
- Affably Evil: Heartless always shows a congenial smile in his face and acts friendly towards everyone.
- Big Bad: After his introduction in the Rail Zeppelin arc the rest of the series focuses on stopping him.
- Curtains Match the Window: His hair and eyes are the same shade of red.
- Cursed With Awesome: While his spatial manipulation magic is the result of having his heart stolen by faeries, with each use resulting in indescribable agony on his part, its very existence grants him a massive advantage as a mage. His ability to freely teleport himself and things as large as a Child of Einnashe is a degree of power most mage would consider Age of Gods category magics!
- The Faceless: Of a sort, due to Case Files' nature as a novel series. Though he was introduced about halfway through the series there was no artwork of Dr. Heartless until the final story arc, so while his appearance was no secret to the characters, fans had no idea what he looked like for several volumes after his introduction. Of course, the manga and anime avert this due to being visual mediums.
- Freudian Excuse: He was betrayed by his fellow apprentices, but rather than blaming them he blames the mage society that allows such betrayal to exist. To that end he wants to tear down modern mage society by returning to the Age of Gods.
- Green Thumb: He had studied in the Botany department of the Clock Tower in the past. Which likely helped explain why he was so knowledgeable about the Child of Einnashe and how to use it as a weapon.
- Heart Trauma: His heart was taken by fairies, hence his alias. An empty void rests where his physical heart would be now.
- Help Yourself In The Past: In an homage to Shirou and Archer, his past self as Kurou Adashino was taught by Heartless from the future.
- Hero's Evil Predecessor: He was the head of the Modern Magecraft department before Waver.
- Locked into Strangeness: His hair turned red during his time in the land of fairies.
- Magical Eye: His Mystic Eyes of Usurpation let him take over someone else's vision, such as forcing them to look in a specific direction. This is how he was able to make Karabo kill Trisha, by using his Eyes of Usurpation to force Karabo to look at Trisha and activate his own eyes. It was originally a Mystic Eye of Finding, just like his sister, Hishiri Adashino.
- The Man Behind the Man:
- While he is introduced in the Rail Zeppelin arc, he is also tied to several of Waver's cases that occurred before then in both the anime and novels.
- At a stretch, you could argue that Olga Marie's father, Marisbury Animusphere, is this for Heartless himself. Marisbury hiring Heartless to investigate the Grail War is where Heartless learned about Servants and got the idea for his plans, but Marisbury had nothing to do with it beyond that.
- Only Known by Their Nickname: Heartless is all he's called until the final volume, where we learn that his real name is Kurou Adashino.
- Power at a Price: His teleportation magic makes him feel like his heart, which no longer physically exist, is being torn straight out of his body with every use! The fact that he can use it without a break in expression is a true testament to his will.
- The Reveal: He's not Hishiri's adopted brother, he's her half-brother.
- Shadow Archetype: To Waver. Both were heads of the Modern Magecraft department, both are Only Known by Their Nickname, and both are obsessed with Iskandar - the difference is the lengths Heartless will go and the people he'll hurt in order to summon him.
- Shapeshifter: When his role during the events of the Rail Zeppelin case was revealed, it also simultaneously shows he was posing as Caules the entire time, demonstrating he has powers something akin to this.
- Stable Time Loop: Kurou was taught by a man named Dr. Heartless. He eventually fell into fairyland, and when he escaped he discovered that he had gone years back in time as fairyland is outside the temporal axis. Then he becomes Dr. Heartless and teaches his younger self.
- Villain Teleportation: With the chant "Overturn thyself, my heart," he can use teleportation magecraft. He weaponizes it to teleport a 'Child Of Einnashe' to attack the train in episode 12.
- Reused Character Design: Gray can sense that beneath the Corpse King's helmet they're also a Saberface.
- Virtual Ghost: Like Add is to Kay, the Corpse King is a copy of Altria's personality made with Logos React, one of the superweapons of Atlas. The cult's plan was that once Gray's body became a perfect copy they would take out her soul and then implant the Corpse King's in her body, effectively resurrecting King Arthur.
- Bad with the Bone: The Crudelis family's magecraft is to make golems with their bones, and is directly compared to how the Eltnam family makes weapons out of their nerves. Besides the large humanoid Tangere, Latio's other bone familiars include giant spiders, wolves, and birds. They don't count as undead, which Gray notices while fighting them because of her anti-undead specialty.
- Implacable Man: Tangere took a hit from Rin that back in Fate/stay night actually managed to kill one of Berserker's lives, and while it blew a hole through his head it didn't stop him since he's empty inside.
- Literal Split Personality: Tangere is actually a piece of Latio's mind that thinks separately from her with Atlas's signature Memory Partition ability.
- Uncanny Valley: In-Universe, Gray describes Latio as being so pretty that she looks artificial.
- Whip It Good: Tangere has a bone whip.
- Historical Gender Flip: Subverted. Although the mythical Wuzhiqi was a male and this one appears to be female, it was actually only her Remote Body that was. Waver figures out the real Wuzhiqi must be a male because according to ancient Xian lore, female deities are capable of out-of-body experiences, while male deities need to gather magical energy to create temporary bodies. Her solid, physical body suggests she's a male deity.
- Magic Eye: Gray gets paralyzed on the spot when making eye contact with her.
- No-Sell: Older Mystery defeats newer Mystery, and so as a Xian she is completely unaffected by modern-day magecraft.
- Remote Body: The body that Ergo destroys at the end of volume 1 wasn't her real one.
- Shapeshifter: Has taken on forms such as an eagle, a strange monkey creature, and a humanoid. Given the real Wuzhiqi of legend, the monkey creature would be her true form.
