Main
Fran Madaraki
Voiced by: Ami Koshimizu (on the CD drama)
Created by Professor Naomitsu Madaraki, the world's greatest medical doctor, Fran was given superhuman surgical skills and left to handle the Madaraki estate and its engineered inhabitants. She is frequently sought by those eager to make use of Naomitsu's or her skills. Unfortunately, while given incredible skills by the Professor, she has also been left with an extreme aversion to killing, and possesses an almost childlike naïveté in regards to the often horrific consequences of her actions.
- Artificial Human: Like all of Madaraki's creations, Fran is a human made out of multiple body parts which are simply pointed out by the stitches.
- Ambiguous Innocence: Played for laughs. She generally doesn't realize that some of her actions, namely the ones that have the victims begging for death, are unethical. She's been called out on a few occasions, and there are even a few instances where she's fully aware of the horrific implications without anyone bringing it up... but still doesn't care as a result of her "all life is beautiful" philosophy. She's like a kid, if a kid has the power to mutate people for fun, profit, or both.
- Be Careful What You Wish For: Not for Fran herself, mind you, but a lot of her clients asking for plastic surgeries (like the one wanting immortality with eternal beauty) learned this the hard way. To be fair, they happned to be Too Dumb to Live.
- Beware the Nice Ones:
- She only wants the best for humanity and is easily swayed by sob stories. However, she is also the direct cause of many plagues on humanity, revealed to us Once an Episode.
- In one chilling scary case, she notes to a politician (who just tried to have Dr. Amatsuka assassinated) that even though Gavrill will tear him limb to limb for the act, Gavrill is a saint compared to her when she gets angry. This is because Gavrill will at least let him die. She then lets him know, on no uncertain terms that she knows he was responsible for the assassination attempt and she is not happy about it.
- In one chapter of Frantic, some monsters that moved out of the mansion to a lake house are killed in cold blood by a group of local university students, who then proceed to use the contact info the monsters had to call the rest of Fran's creations over in order to kill all of them. Learning this has Fran enter a Tranquil Fury, harvesting their organs to save her friends and turning what was left over into... an unknown "something" that now dwells in the lake.
- Blue-and-Orange Morality: Apparently, it's more of a doctor's perspective on "do no harm", but she sees no problem with others whose fates are worse than death. She also doesn't mind killing fully sapient clones, figuring that as long as one sample of the individual remains, s/he is not actually dead. And, yes, that means she considers the original and the clones equally expendable. From what we get, killing clones isn't murder to her and she's strongly opposed to murder, though, it's fine if she gets to harvest your organs. Her idea of medical ethics, in simple terms, is like comparing apples to bricks. She does seem to have some self-awareness (see "Hidden Depths") about the subject, though, she doesn't act on that as much some of her patients would have liked.
- CloudcuckooLander: Damn, is she ever. She's what you get if you combine regular cloudcuckoolander with the skill, mind, and reputation of a Black Jack level surgeon. She means well, however, her idea of "meaning well" would leave much to be desired, probably not helping is that she's been programmed this way.
- Covered with Scars: Stitches, to be exact.
- Curtains Match the Window: She has blonde hair, and according to the covers and colored illustrations has yellow eyes.
- Cute Monster Girl: Try asking her creator why she and her sisters look so adorable.
- Ditzy Genius: She can get a little genki at times, but she operates better than others nevertheless.
- Everyone Has Standards:
- Some people of unusual tastes manage to out-creep, though the argument could be, as a doctor, she has issues with people who obsessively cause themselves pain.
- Despite her Blue-and-Orange Morality, she recognizes that that her estate far too dangerous to raise a child in, as seen in Chapter 52 of the sequel.
- Frankenstein's Monster: Very similar visually, with the stitches and the head bolts. Frankly, she even makes her own monsters, thus she also counts as a Dr. Fakenstein.
- For Science!: People do observe that she could be her creator's replacement. Taken deeper when she split in half, as Fran L takes a bloodshot eye on others who doesn't take their jobs seriously.
- Glasgow Grin: Although that's just her stitches sticking out.
- Half the Man He Used to Be:
- She accidentally gets split straight down the middle by a laser in Chapter 60: "Left And Right". She simply replaces the necessary things for each half, ending with two Frans (which later become one again). That's right, she managed to survive and cure BISECTION.
- When she was in a hotel besieged by Gavril and her army, Fran had to escape by a vent. However turns out her butt was too big to fit through, so she had to abandon it and ends up wobbling back home on her two arms.
- Helpless Good Side: While recovering from getting cut in half bilaterally, Fran-M is nice and actually cares about her patients' quality of life, but is rather a pushover.
- Hidden Depths: While she's generally oblivious to the consequences of her experiments, there are times that hints that she works towards a larger goal in the end. This is most notable when she's hired to protect a wealthy politician, who attempted to have Dr Amatsuka assassinated, from Gavrill; she notes that while Gavrill is pretty straightforward with what she wants to do to him, Fran can be just as cruel, if not as deadly.
- Les Yay: Invoked a couple of times with Veronica in-universe, and pretty much played straight when her two halves finally reunite...
- Loophole Abuse: She is distressingly effective at exploiting technical loopholes in her moral imperative to preserve life to the greatest degree possible to punish terrible people when pushed far enough. Other cases have been mentioned, but in the aforementioned incident with the university students at the lake, she uses bizarre — though logically sound and internally self-consistent — reasoning to interpret one's protest that they're "allies of justice" as "we volunteer to be living organ donors to save your friends and patients."
- Losing Your Head: Occasionally has her head laying somewhere else than on her shoulders while her body is working on something, for some reason.
- Love Freak: She's a "lover of love" and eager to help perform procedures that she thinks will bring couples together. That'll give you only a slightly higher chance of a not-that-bad ending.
- Mad Scientist:She completely lacks any understanding of the word squick and does half of what she does For Science!, and the other half to save lives... no matter the cost to quality of life.
- Mad Doctor: While Fran means well, the problem is that the concept of "quality of life" takes a backseat in the process.
- Mad Scientist's Beautiful Daughter: She is the creation of Dr. Madaraki, after all, though she's more of a Cute Monster Girl version of this trope
- Madness Place: Compare normal Fran to operating Fran. She's more off-kilter.
- Mix And Match Person: She seems to be the conglomeration of several different individuals. This is pretty obvious considering her skin looks like a jigsaw puzzle.
- Motherly Scientist: Well, certainly sees herself as one, as she takes care of her creations and her creator's on a daily basis. The truth is... somewhat more complicated.
- Multi-Armed and Dangerous: Extra arms attachable for more intense surgeries, so whenever she gets more amoral, it veers into this trope.
- Multi-Armed Multitasking: Often attaches extra pairs of arms for surgery. Which, given the common outcome, leads to the above trope.
- Obliviously Evil: Doesn't seem to be aware of the horror she constantly causes with her work. Nor does she seem to care that much when she does realize it, though this is mostly because she thinks that no matter how shitty a life can get, it's still better than death.
- Off with His Head!: Almost ended up with this—a hired killer slit her throat deeply enough for her head to barely hang on to her neck. Predictably, she not only survives, she performs emergency surgery on herself and lives on like normal.
- Only in It for the Money: On occasion. Super biology is expensive, after all.
- Nice Girl: She is very polite to people and despite having serious case of Blue-and-Orange Morality does genuinely want to help people despite that it can end up in disaster at times.
- Parental Incest: Has a crush on her creator, though this seems to be one-sided.
- Ping Pong Naïveté: Depending on whether a chapter - or even an individual scene - needs her to play the instigator or the Only Sane Man, she can whiplash from ice-cold lectures on how all attraction amounts to chemical reactions and evolutionary instincts to a bleeding-heart Love Freak that hands full-body augmentations and bioweapons to anyone with a sob story - even schoolchildren. "Left and Right" addresses this full on, showing she indeed has the potential for both stored in her brain; it's just that they never seem to average each other out.
- Red Oni, Blue Oni: The Blue to both Veronica and Gavril, though not so much to Veronica. And then she manages to establish this dynamic with herself in "Left and Right" when she ends up as two Frans, with one being aggressive, greedy and rude, but logical, while the other is much more passive, gentle and kind, but so altruistic that other people can easily push her into doing what they want.
- Science Hero: Uses science as her best solution for anything, but whether what she ends up doing is a good solution or not, is debatable to say the least.
- Slasher Smile: When about to commence surgery.
- Super Doc: Admittedly, she is probably one of the best surgeons in the world, being able to bring back the dead and do almost every kind of body modification. Despite all that, her operations tend to have nasty side-effects or indirectly bring about trouble.
- Tareme Eyes: Gives her a sweeter look and she is indeed very nice on a good day.
- Thou Shalt Not Kill:
- Fran will do whatever it takes to save a life, even if it means giving the patient a Fate Worse than Death.
- She's quite talented at finding loopholes around this when she has sufficient cause to, whether it's merely inflicting a Fate Worse than Death, or empowering someone else to kill the people she wants dead under the excuse that it was up to them to use their powers and she had no way of being certain how they would. She also tends to be indirectly responsible for the deaths of people, sometimes en masse, when she didn't intend that to happen and is usually even oblivious about it.
- If someone is about to die anyway, she does let Adorea harvest the person's organs. This has to happen before death or the organs could suffer damage.
- Although she is quick to chastise Veronica for killing people, the same chapter has her remark that it isn't so much that she cares about the act of killing people (she doesn't), but that she strongly believes death is never the solution.
- And then there is the one time she hoped to kill Gavrill by blowing her up with a grenade. Though, considering what we know about Gavrill, maybe Fran might have a point.
- Verbal Tic: The official English release gives her a habit of drawing out some of her vowels in a weird waaaaaay.
Veronica Madaraki
Voiced by: Minori Chihara (on the CD Drama)
Another, later, creation of the Professor, Veronica was created to serve as his bodyguard and is thus very much willing to resort to murder, though quick about it. She initially shows up as an antagonist, attacking the Madaraki estate after having been separated from the Professor. At first quite hostile to Fran, out of envy of her comfortable life and dislike for Thou Shalt Not Kill attitude, though after some experiments by Fran she becomes her willing bodyguard and foil.
- Absurdly Sharp Blade: Her weapon. The blades she hid in her sleeves are so ridiculously sharp they could vertically slice grown men in twain with little effort.
- Action Girl: Carries a pair of Absurdly Sharp Blades beside her, and is normally considered as Fran's personal bodyguard.
- Artificial Human: Like Fran, she is a stitched together human made by Prof. Madaraki.
- Badass Adorable: A timid little girl, who gets easily flustered and can be pretty cute. She is also an assassin who whips up blades out of nowhere and effectively kills anyone in her way.
- Big Sister Attraction: The manga implies several times that she's infatuated with her sister Fran. It's even lampshaded in the final extra chapter — where Fran immediately notes (quite accurately) that Veronica has a habit of attaching herself to literally anyone who shows her a shred of affection.
- Blade Below the Shoulder: Has an arsenal of weapons under her sleeves.
- Butt-Monkey: Things rarely ever go well for her and is usually played for comedy, with a few exceptions.
- Covered with Scars: Like Fran, she has visible stitch lines on her face. Unlike Fran, her clothes hide an abundance of battle scars.
- Cute Monster Girl: Like her sister. Stitched up though she may be, she looks incredibly cute.
- Desperately Craves Affection: As a result of having no normal friends and her sisters not really being the best source of it.
- Funsize: After being sliced in half and torn apart by Gavrill, Fran temporarily makes a smaller version of her.
- Hammerspace: Those blades of her are about as long as her entire body. Somehow, she seems to manage to hide them inside her sleeves.
- I Just Want to Be Loved: She doesn't seem to want much more out of life than someone who treats her with basic decency. Considering her sisters are a morally confusing Cloud Cuckoolander and a sadistic murderous lunatic respectively, this isn't too surprising, but it also sets her up for being easily manipulated on some occasions.
- Knight Templar: She was built to defend her target by killing any threat. The problem, as later chapters make clear, is that her definition of "threat" is rather lower than it should be. "Girl's School" opens with her killing people for coming near Fran's mansion, and she's pulled her weapons for people just teasing Fran.
- Little Miss Badass: She can hold her own even when faced with an army of heavily armed grown men.
- Living Weapon: Designed as one to act as a bodyguard.
- Love Martyr: Perhaps. After all, she did go from antagonist to doting little sis after a round of experimentation.
- Murder Is the Best Solution: Made with this in mind, and serves as a foil to Fran with how quick she is to resort to it. However, she always opts to go for quick and painless death as a courtesy to her victims.
- New Transfer Student: When Fran's too busy to look after her or she does something wrong, she simply sends her to school for a good month.
- One-Woman Army: Not to the extent of her older sister Gavril, but still. She can definitely do a surgery that would usually require an entire crew to perform successfully
- Restraining Bolt: Has a bomb implanted inside her body, which usually goes off if she ever goes rampant. Fran took this right off in order for her and Veronica to escape Gavril.
- Sand In My Eyes: Near the end of Chapter 25.
- Shrinking Violet: In contrast to her nature as an assassin, she is terribly shy and has a hard time getting along with other people.
- The Worf Effect: Most of the fights she partakes in an amount to her slaughtering the hell out of her enemy. Her fight with Gavril, on the other hand, was the other way around.
- Walking the Earth: What she did with the Professor and in-between his leaving and her arrival at the Madaraki estate.
- White Gloves: Sports these whenever out in public, at least most of the time.
- Why Did It Have to Be Snakes?: Terribly afraid of ghosts. She has no problem with zombies, however.
- "X" Marks the Hero: The scars on her face form an X shape. It's sometimes hard to see in full because of her hat, but it's there.
Okita
A man with the body of a cat (or possibly a cat with the head of a man), Okita is another member of the Madaraki Estate, and much more down-to-earth than Fran. He usually serves as a voice of reason, that is, when Fran listens to him.
- Butter Face: Inverted. He has a handsome face, but the body of a cat. When he needs to go out in public, though, he'll use a human bodysuit that makes him look more like a standard handsome guy.
- Cat Folk: A man with the body of a cat; or possibly a cat with the head of a man.
- Cheshire Cat Grin: Appropriately enough, in the first chapter.
- Chick Magnet: On the few occasions his head is put on a human body, he immediately seems to attract attention from random women (and Veronica).
- My Instincts Are Showing: As seen when you dangle a fuzzy object on a string in front of him.
- Only Sane Mancat: Is often the one to mention (to himself) that what happens is horrifying, but that Fran doesn't even realize.
- Our Sphinxes Are Different: He is technically a sphinx considering he has a feline body with a humanoid head.
Supporting Characters
Gavrill Madaraki
Fran and Veronica's psychotic, cannibalistic elder sister, and the only recurring villain in the series. Gavrill is one of the earliest creations of Naomitsu Madaraki. She is violent and quite foul-mouthed. Also, unlike her younger sisters, she places absolutely no value on human life.
- Aloof Big Brother: Physically, she is the most powerful out of the three sisters. She's also a complete jerkass whose moments of kindness towards anyone can be listed on one hand. It's telling that her debut sees her attempting to murder both her sisters, and that the outcome of that entire situation was little more than a ceasefire where they agree to ignore each other whenever possible. Veronica in particular is always the most on-edge whenever they happen to cross paths, because Gavrill will happily mess with her baby sister regardless of that arrangement.
- Awesome by Analysis: With her sense of smell, she can basically deduce everything about a person. And if her "lessons" during her time as high school teacher is anything to go by, she's one hell of a Diabolical Mastermind. Sherlock Holmes would be screwed trying to outsmart her...
- Ax-Crazy: Just to give you an idea, her preferred form of combat is transforming herself into a huge wolf-like beast and ripping her opponents to shreds. All the while with an insane grin on her face. It's slightly subverted as well, though, for as insane and bloodthirsty as she is, she's very sly and intelligent.
- Badass Teacher: Towards the end of the original series, she begins a stint as a high school teacher. She was forbidden from killing anyone, but she managed to become incredibly well-liked because of her blunt demeanor and good advice. Granted, her first piece of advice was telling some students who attempted to rape her the best way to find an vulnerable target and how to avoid being caught afterwards.
- Berserk Button: If you value your life even a little, then for the love of Chrysler, do NOT fuck with Dr. Amatsuka.
- Blood Knight: Loves to slaughter and even eat her victims sometimes.
- Body Horror: This is what happens when a character is labeled a "transformer" without being a robot. Apparently, she is capable of rearranging every part of her body (muscles, organ, even bone) to her desire as long as she has the willpower to do so, allowing her to produce whatever she needs to maul someone at a moment's notice with her flesh.
- Brutal Honesty: As a teacher, Gavrill is known to give her student advice that are... unconventional and brutally honest, such as telling a decidedly unattractive boy to "go get plastic surgery" if he wants to be popular with girls.
- Cute Monster Girl:
- Mostly a matter of opinion, but when she isn't looking scary or creepy, she can actually look pretty cute.
- In Frantic, she employs this by shrinking down to the size of a 10 year old, still retaining her stitches. She always uses this to get her opponent to drop their guard so she can get close enough to butcher them.
- Dark Action Girl: Fights, swears and brings lots of bloodshed.
- Determinator: Fran notes that, until she saw Gavrill, she thought that a "transformer" was impossible because you need to have extremely strong willpower to keep your body from imploding into the various tiny muscular organs that now made up the body. Gavrill not only can keep her form without any sort of effort, but can also change into her combat form fluidly, indicating she has exceptionally strong willpower to maintain her body.
- Desperately Looking for a Purpose in Life: Perhaps not particularly desperately, but in chapter three of the sequel, Gavrill does seem sad when she wonders what purpose her father could have created her for.
- Diabolical Mastermind: For an ultra-violent cannibal monster, she has got great wits and some persuasion skills. She controls an gang (read "army") of thugs and she can be so insightful and convincing as a school counselor, she could very well become a professional Crime Boss like Kingpin if she ever wanted to.
- Fangs Are Evil: The most unambiguously evil out of the Madaraki sisters, and sports these.
- Gender-Blender Name: The name "Gavrill" (or "Gavril") is a male name and a variant of "Gabriel", with the common female equivalents being "Gabrielle" or "Gabriela/Gabriella".
- Genius Bruiser: Despite her Ax-Crazy tendency and brutal efficiency in fighting, she is quite smart.
- Hot Teacher: Temporarily became a high school teacher, and many male students blushed when she introduced herself to the class.
- I'm a Humanitarian: The very first thing we see her doing is eating the severed arm of a guy she had killed moments earlier.
- Jerkass: The series has a lot of them, but she's one of the worst. As if casually slaughtering people for no apparent reason isn't enough, she loves to see people suffer, mentally or physically. A notable example is in Chapter 59, where Veronica pretty much begs her to tell her who were the guys who had murdered her best friend. Gavrill tells her, but then forbids her from laying a hand on any of them or else she would kill Fran and everyone else that lives in the Madaraki Mansion. Why did she do that? Because she wanted her sister to wallow in despair. Holy shit. note
- Jerk with a Heart of Gold: Despite her sadsitic, violent and ruthless nature she does show compassion and kindness as the series goes on, such as genuinely caring about Dr. Amatuska and being nice to him.
- Even though she told Veronica not to go after the people who killed her friend because she wanted her to "wallow in despair", it's implied that she said it so that her sister wouldn't go after them in a vengeful rampage. Besides, it's also implied that she found out that they were about to die anyway.
- She is very friendly toward Fran and does keep her word, like her promise to not kill any students while she works as a teacher.
- The Juggernaut: Absolutely nothing can stop her. She ripped Veronica apart like she was tissue paper, withstood sustained machine gun fire while laughing, and a tactical nuclear strike (despite vaporizing the island she was standing on) did little more than mildly annoy Gavrill because she had to swim all the way back to land. Although she implies a stronger nuke might have been able to kill her.
- Kaleidoscope Hair: According to the cover of volume 6, she has purple-colored hair and according to a later volume, it's reddish-brown. As a shapeshifter, she can probably change her hair color. Or the artist can.
- Lack of Empathy: Pretty much none for anyone who isn't named Doctor Amatsuka. Even when she does begin showing such traits towards others, the biggest example being forcing Fran to give the Fire-Forged Friends she made during that chapter medical attention, she never admits it.
- Lady Swears-a-Lot: Hell yeah. Loves to pepper up her speech with f-words and c-words."I'M FUCKIN' INVINCIBLE!"
- Living Lie Detector: Her senses allow her to detect liars.
- Made of Iron:
- When Dr. Amatsuka was attacked, Gavrill went on a Roaring Rampage of Revenge and killed one of the men responsible for it. The guy's bodyguards obviously tried to defend him by basically unloading their machine guns at her. She didn't even flinch. Hell, she even laughed all the way.
- As mentioned above, a low-yield nuke was only a minor annoyance to her.
- Meaningful Name: Greek/Russian male-variant of "Gabriel", which is Hebrew for "God is my strong man".
- Morality Chain: Doctor Amatsuka is this for Gavrill during the chapter where she serves as a relief teacher. It's only his requests that stop her from literally eating her students despite her general contempt for them.
- More Teeth than the Osmond Family: Especially when she goes beast mode.
- Navel-Deep Neckline: Her usual attire includes only an unzipped jacket for her top, with her bare skin showing through the opening, so everyone gets treated to shots of this.
- Nigh-Invulnerability: Because she can transform her own body, she can open up holes in her body to let attacks go through her. Also she survives a heavy bomb dropped on her head that destroyed a small island and then swims to shore while out in the sea.
- One-Woman Army: She managed to exterminate almost an entire legion of humans who can clone themselves so they would never run out of soldiers.
- Pet the Dog:
- When Veronica starts to cry in the epilogue chapter for the original run, after Gavrill and Fran have spent much of the chapter bullying her, both of them comfort their youngest sister in what is the only sisterly moment the three of them share in the entire series.
- Chapter 3 of Frantic has an even stronger one, where she serves as the relatively levelheaded leader for the Ragtag Bunch of Misfits trapped on an island-sized Deadly Game (despite repeatedly telling them to quit following her), and even asks Fran to resuscitate them after they all get gunned down by the Herr Doktor behind it all.
- Red Baron: Her violent tendencies and the form she often takes when she gets serious during battles (As well as her flesh-eating habits) have earned her the nickname "The Wolf".
- Red Eyes, Take Warning: According to the cover of volume 6, at least.
- Ruthless Modern Pirate
- Sadist: Takes pleasure in her merciless deeds as the leader of a murderous and plundering gang.
- Shapeshifter Weapon: A human weapon, to boot.
- Slasher Smile: Her default expression.
- The Sociopath: She kills, doesn't really care about people and is fine with it.
- Statuesque Stunner: The tallest recurring female character and acknowledged to be attractive In-Universe.
- Super-Senses: Specifically, an incredible sense of smell, to the point where she can identify the perpetrators of a crime just by sniffing around the area. However, she can't exactly turn it off, which means what few things she actually likes about her job as a high school teacher are overshadowed by the constant smell of semen and menstrual fluid.
- There Is No Kill Like Overkill: Every time Gavrill kills somebody, you could bet that it will be very messy and bloody (and probably unnecessarily so), especially with this manga's art style, showing brains and intestines being spilled and so on.
- Your Days Are Numbered:
- In a small blink-and-you'll-miss-it moment, she remarks that she doesn't plan on living to old age and was asking Amatsuka if he'll outlive her. Judging by Amatsuka's response, even if she outlives him, it wouldn't be that much longer. Note that Amatsuka is an old man who lived through World War 2.
- This is somewhat elaborated on in a Frantic chapter; if Gavrill's inhibitors aren't regularly tuned, even her intense willpower isn't enough to prevent her from losing her mind and uncontrollably mutating into a nigh-unstoppable abomination. Amatsuka is the only person she's willing to let perform the tune-ups, despite him teaching some of his younger associates the proper method.
Adorea
A young girl saved from death by Naomitsu Madaraki, though by the time he did it was too late to fully restore her. She now serves as a walking organ bank, consuming and storing organs for whenever they might be needed.
- AB Negative: To be precise, because she stores so many organs for Fran to use, she's got a lot of different blood types in her body, the dominant type constantly changing. This becomes a major plot-point in chapter 57.
- Body Horror: She looks relatively normal most of the time (she is covered from head to toe in bandages, but aside from that, she looks normal), but in chapter 57, she's eaten so many students that it makes her look inhumanly and horrifyingly big.
- Extreme Doormat: Outside of her origin story and one of her Day in the Limelight chapters in Frantic, Adorea does very little purely of her own recognizance and Fran comments in one chapter that she'll follow any instructions she's given. Unfortunately, the "instructions" in that chapter were a snide, mocking statement that if she doesn't like being mistreated for having a variable bloodtype, she should get some proper blood. This ultimately leads to her devouring nearly an entire high school so she can have whatever "proper blood" she needs for anything she wants to do. Fortunately, Fran catches on to what's happening soon enough, and Everybody Lives.
- Humanoid Abomination: Under the bandages, her face appears to be some mass of tentacles.
- I'm a Humanitarian: That's one of the ways she can store spare organs and different blood types for Fran. It makes her look a bit chunky, though. It's also not necessarily lethal, as she can spit them out before they die (Fran does still need to heal them, though).
- "Pop!" Goes the Human: In chapter 57, her body basically goes like this and her zippers all break open because she's eaten so many students. It's as nasty as it sounds, but surprisingly and fortunately, she survives.
- The Ingenue: Well she's definitely gentler and kinder than the sisters but as for innocence....
- Walking Transplant: Complete with zippers and organ-stealing face.
- Why Did It Have to Be Snakes?:She's terrified of cockroaches. It's not really clear why, just that she is.
Rumiko Kuhou
A recurring minor character; A female police officer who crosses paths with Fran and/or the results of Fran's experiments several times.
- Bespectacled Cutie: A cute, bespectacled young policewoman with a meek personality.
- Butt-Monkey: In just about every chapter with her, something happens at the expense of her sanity. Those things were mostly Played for Laughs.
- The Chew Toy: Briefly served as this to Gavril. Fran's plan to stop Gavril's rampage was to make an army of Kuhou clones, shipped them to an isolated island, and then let Gavril slaughter as many Kuhou clones as she wanted until she calmed down.
- Fair Cop: She's young, and really, really cute.
- Girls Love Stuffed Animals: From what little we've seen of her room, we can at least tell she has quite a few stuffed animals.
- Sanity Slippage: She snaps during one of the chapters featuring her after finding out the latest batch of clones of her Fran made are being used for the fantasy of some lightly crazy dude. And as if that wasn't bad enough, she is then mistaken for one and turned into a monster. At one point, she was attacked by the monster of the week, despite having nothing else to do with (or even appearing in) the chapter. She immediately chalks it up to Fran's antics and never mentions it again.
- Tomato in the Mirror: Whenever Fran needed clones for anything, she usually comes to Kuhou for the necessary "genetics". Due to her method of cloning (which was Cell Mitosis done on a full human being), the implication is that Kuhou seen in subsequent chapters isn't technically the same girl that Madaraki keeps kidnapping off the streets. Given Fran's loose moral ethic, she sees no problem in this.
- Unexplained Recovery: A few chapters after being transformed into a Cute Monster Girl, she is seen again as a human, with no explanation of how she was turned back or even the slightest mention of her time as a monster girl. On the other hand, Fran has a LOT of clones of her...
- Sympathy for the Devil: She can't help but feel some sympathy for the Serial Killer in chapter 28, now that Fran's entered the picture. ...That is, until he masturbates and ejaculates on her, which makes her realize how much of a lunatic the guy really is.
Doctor Amatsuka
Another recurring minor character. He's been a friend of the Madarakis (Even Gavrill) since the days of the old Japanese Empire. His various achievements have earned him the title of Viscount of England. He sometimes aids Fran in whatever she's doing at the time, and performs check-ups on Gavrill every month.
- Miniature Senior Citizens: Befitting his age, he's quite a bit shorter than most characters.
- Morality Pet: To Gavrill. He's the only man she respects and the only one who can keep her murderous instincts in check.
Professor Naomitsu Madaraki
The world's greatest medical doctor, and father/creator of the Madaraki sisters. He left his lab to Fran while he's busy Walking the Earth.
- Alternate Character Interpretation: In-universe, people tend to have wildly different opinions on him. The general public (at least, those who know about him) tend to regard him with fear and awe, Fran completely idolizes him, and Gavrill loathes him.
- Evilutionary Biologist: He's not "evil", but definitely not entirely ethical either. Yet he does seek to improve humanity with his efforts.
- The Ghost: He's mentioned a few times, but never actually seen in person.
- He Who Must Not Be Seen: We don't get an indication as to what the guy looks like, besides a flashback, and his face was obscured the entire time, though we figure he might have been a case of I Was Quite a Looker..
- Mad Scientist: What little we see of his recent work suggests that Fran is nowhere near his level yet. Apparently he's been creating and breeding Kaiju.
- Missing Mom: To Fran, Veronica and Gavrill.
- Retired Monster: He was part of the Japanese Army during WWII, and given his reputation for horrific experiments it isn't much of a leap to assume he was involved in some thoroughly nasty stuff.
- Truly Single Parent: He created his three "daughters" Gavrill, Fran and Veronica, completely from scratch.
- Wandering the Earth: Before the series, he left his lab to Fran to do something and it's not really clear why he left but we do know it had something to do with him creating and breeding Kaiju.
- The Unreveal: We see a young Naomitsu when we're introduced to his colleague Dr. Amatsuka, who has a flashback to a moment the two shared. Unfortunately, Naomitsu's face is partially obscured by the shadow cast by the brim of his naval hat. On top of that, when we see a young Dr. Amatsuka, he looks nothing like the wrinkled old man in the present day, so there's no way to even guess at what Naomitsu would look like now.
Sentinel
All of them
- Cool Bike: As a Kamen Rider joke, each Sentinel gets their own motorcycle, and all of them are big, cool, expensive bikes.
- Corrupted Character Copy: All four of them are based off of various Kamen Riders, and their names are naturally unsubtle parodies as well.
- Toudou is one to Kamen Rider 1, Takeshi Hongo. His eyebrows are nearly as big as the guy's. Instead of being roboticized by Shocker, however, Toudou gets his cybernetics from Fran, and by the end of his story becomes the equivalent to one of Shocker's weekly monsters.
- Jumonji is one for Kamen Rider 2, Hayato Ichimonji, although his character journey has obvious parallels to Hongo's in the first thirteen episodes, even travelling around the world after being ambushed on Black Lotus' home turf.
- Those Who Fight Monsters: To the point that they became even worse. Heck, they even start attacking each other!
Takeshi Toudou: Sentinel I
- Anti-Hero: He will beat the crap out of anyone who breaks the law, even if it's something small or they were already sentenced for their crimes. And since he has superhuman strength, his attacks can leave quite a bloody mess, and a lethal one.
- Career-Ending Injury: He was a pretty good runner, up until he wore out all of his cartilage by pushing himself too hard. By the time he first gets enhancements from Fran, his damage makes it so he couldn't move around without a wheelchair.
- Create Your Own Villain: The family members of the criminals he murdered eventually don costumes of their own and start fighting him out of vengeance.
- Retcon: Turns into a monster and joins the "evil" organisation but in a later chapter featuring Sentinel, he is back to being the "hero" he was and fights alongside the second Sentinel. Or maybe it is a Plot Hole. It is talked about on Headscratchers.Franken Fran.
- Super-Strength: After getting modified by Fran, he gets this. It eventually becomes his downfall after choosing to get himself so strong, he becomes a monstrosity.
- Unwitting Instigator of Doom: At first, his enhancements were just to allow him to walk and compete again. However, many other athletes heard about his surgery and started getting them as performance enhancements, leading the public to decry his surgery as him trying to cheat and getting bullied as a result.
Hayato Jumonji: Sentinel II
- Face–Heel Turn: After finally reaching the base of the Black Lotus Organization, he asks their faceless leader what they are planning. Turns out, they want to destroy the world...by making it a better place. They want to improve health and welfare, settle disputes, help out developing nations, distribute wealth and bring peace, so that the florishing amount of humans will eventually bring on their own demise, because things can only get worse when they are at their best. Jumonji gets mindfucked by this idea, and then, the civilian family members of those he killed start ganging up on him. He starts killing them, and from that point on, becomes a Knight Templar terrorist as detailed below.
- Glory Hound: While he legitimately looked up to the first Sentinel, he also wanted a life of excitement and adventure, which he got when he started going after Black Lotus.
- Knight Templar: My God. This guy believes that in order to save the world, he has to kill as many people and ruin as many lives as possible after his Face–Heel Turn, and still thinks he is on the side of good. Also, anyone who even looks suspicious gets accused of being with the "Black Lotus Organization" and beaten to a bloody pulp. Or killed.
- Scarf Of Ass Kicking: Adds a scarf to Sentinel's wardrobe, in addition to wearing one in his casual outfits.
- Super-Strength: Said to be even stronger, and therefore more dangerous, than the first.
Shirou Kazekiri: Vengeance III (Sentinel III)
- Revenge Before Reason: What this guy runs on. After initially fighting against Sentinel 1 and 2 to avenge those he killed, he got a kick from it to the point of arousal. Now he is so willing to fight for vengeance, that he'll even get people to be murdered just so that he can avenge them. One time he even crashed into a bus, killing multiple children inside, and then blamed it on the other Sentinels. All just for his own pleasure, and he is fully aware of it.
- Super-Strength: Like the others before him.
Yuuki Joutarou: Sentinel Man (Sentinel IV)
- Good Thing You Can Heal: Invoked by Vengeance, who got Fran to give Yuuki regenerative abilities, but no super strength. Because of this, Yuuki gets beatings that would normally kill a person. Which is what Vengeance planned, since he now has someone to whom he can say he'll avenge him, over and over again.
