Manga / Giant Ojou-sama

A Truly Growing Cast of Characters

Oriko Fujido is the buxom young head of the Fujido Zaibatsu, a group that has a monopoly on Japan’s vending machine industry. Serving at her side is her personal butler, Dr. Sebastian.

Upon her fourth birthday, she asked for and received the ownership of a city from her father and has cared for it greatly in the years since. However, when a monster suddenly attacks the city, Dr. Sebastian slips his ojou-sama an experimental energy drink his team in R&D has been developing. As a result, she quickly finds herself growing into a giantess, matching the attacking kaiju in size! However, it is but the first of a series of Invaders being purposefully lured to her precious city! Will Oriko be able to unravel the mystery of these invading aliens or, at the very least, keep her dignity intact?!

The original one-shot was the winner of Shounen Jump’s Dec 2020 Bronze Rookie Award while the manga series itself took fifth place in the “Manga I Want Animated” contest in 2023.Giant Ojou-Sama is written by Nikumura Q and is distributed by the ''Sunday Webry’’ and, as of now, has six volumes released.

This manga provides examples of:

• Acquired Situational Narcissism: Oriko gets a dose of this after hearing Nakano praise her for her accomplishments at a young age, amplified by Madoka and Dr. Sebastian enabling it. By the time she snaps out of it, she's about to get launched into space to advertise her greatness to the whole world.
• Actually a Doombot: Chapter 56, Oriko's giant alien mother seems to have arrived, and her personality and knowledge line up with what Dr. Sebastian knows about her, but then she starts stealing the city. Oriko, having deduced that this isn't really her mother because of a Character Tic her father had told her about, defeats the fake mother and reveals it to be an android.
• Adults Are Useless: For all that he’s an incredibly capable fighter, able to match and even BEAT Oriko when she’s a giantess, her father does little help when an Invader attacks.
• Aliens Are Bastards: A given for the Invaders as a whole though to varying degrees with Stella and Gimlet as being generally unpleasant, while others are well and truly monstrous.
• Ambiguously Brown: Nakano.
• Attack of the 50-Foot Whatever: Pretty much a majority of the Invaders and, at times, the city’s saviors.
• Attention Whore: Pretty much all of Stella’s antics involve her being this. Midori’s giantess-daydreams often involve her being this as well.
• Baseball Episode: Chapters 70 and 71 have Stella challenge Oriko to a baseball game. Complicated by the fact that the bat and ball are scaled to Stella's size.
• Battle Butler: The alternate timeline's Sebastian, who is strong enough to fight Invaders himself and is totally devoted to being Oriko B's perfect servant.
• Behemoth Battle: Pretty much any battle with an Invader.
• Bilingual Dialogue: The Invaders’ native language consists of lines and symbols that look a lot like a city map. In fact, Oriko’s own city is arranged to read as “Hey! Come and visit my city!” in the language of the Invaders.
• Big Bad: The early Invaders turn out to be sent by Stella who eventually decides to come to Oriko's city herself and launch a full-scale invasion... only for her mothership to malfunction and strand her on Earth. It doesn't take long before she's reduced to a Sitcom Archnemesis who frequently allies and hangs out with Oriko. A straighter example ends up being (supposedly) Oriko's mother, who sends out much more frightening Invaders not only to Oriko's city but to other surrounding cities as well as alternate dimensions.
• Big Bad Wannabe: Stella, one of the few Invaders capable of speech, is also Oriko's petulantly childish nemesis. Her plans of beating Oriko can be described as childish at best and outright incompetent at worst. To be fair, she is technically twelve Earth years old.
• Breast Expansion: A side-effect for Oriko when she grows without wearing a bra.
• Cartoon Creature: It is heavily implied that Gimlet and Dr. Sebastian are part of the same extraterrestrial species, one that appears to be servile to those whom they deem to be “ojou-sama’s” like Stella or Oriko’s mother.
• Cat Fight: Typically occurs between Oriko and Stella regardless, or at times because of, the collateral damage this causes the city.
• Child Prodigy: Nakano Giraffe, a 9 year old boy who moves to Oriko's city partly because the schools allow him to skip grades to the high school level, and partly out of admiration for Oriko's own accomplishments.
  • Oriko herself started university-level courses at 4 years old and finished in two years so she would be able to focus entirely on running her city.
• Comedic Underwear Exposure: Frequently and especially with Oriko, though Madoka has this happen to her on a few occasions.
• Comical Overreacting: Oriko whenever she realizes she’s unintentionally turning into a giantess. Madoka also, particularly when her less than savory habits, i.e. her messy apartment, are discovered by a shrunken Oriko.
• Conveniently Empty Building: Played with. At times the buildings of Oriko’s city are suspiciously quick to be emptied by the populace even when there’s no forewarning of an Invader attacking.
• Curb-Stomp Battle: Inverted and subverted several times throughout the series against some of the Invaders. This happens most frequently whenever Oriko goes truly gigantic, at least comparatively to the Invader she’s fighting at the time.
• Cuteness Proximity: Madoka. Usually downplayed as she keeps things like thinking Nakano is a cute kid to herself, but the first time she sees Sebastian go giant, she's immediately and loudly enamored with how fluffy he is.
• Damsel out of Distress: None of the girls are a pushover at regular size; never mind when they go giantess sized.
• Didn't See That Coming: Happens frequently with Oriko as more often than not, she will somehow, someway, consume a gigantification drink. Oftentimes due to Dr. Sebastian’s “assistance” for problems that REALLY don’t require a giantess to solve.
• Faceless Masses: Parodied. All the regular citizens are depicted as featureless white figures. However, it’s revealed that they’re actually wearing special full-body suits, which allow them to survive the many Kaiju attacks and other giantess-related shenanigans. The readers are also shown a helpful chart, which compares a citizen in normal clothes and a citizen in a protective suit... both of which look exactly the same.
• Fembot: Dorea.
• Fetishes Are Weird: Basically the only thing stopping Midori from actually acting out her daydreams is the shame of other people seeing her get off to her power fantasies. A fact that Madoka uses against her upon figuring her out.
• Forgiving the Accidental Pervert: The girls easily brush it off whenever Nakano Giraffe accidentally ends up in a Suggestive Collision. It helps that he's only 9 years old, and clearly doesn't have any lewd intentions whenever it happens.
• Formerly Fat: When Oriko first met Sebastian, he was overweight having spent three years secluded in his room. Once Oriko is given a city to watch over, she forces him to lose weight.
• Giant Foot of Stomping: Done by the Invaders and the giantess-sized defenders but most notably by Midori when she first went giantess.
• Giant Woman: It is in the name after all.
• Good Old Fisticuffs: Madoka’s method of operandi whenever dealing with Invaders and the use a Megaton Punch.
• Green-Eyed Monster: Initially, Midori REALLY wants to grow into a giantess and deal out some wanton destruction on the city. Oh, and the Invaders too.
• Half-Human Hybrid: Oriko is half-alien on her mother's side.
• Hoist by Their Own Petard: When Stella first arrives, she tries to threaten Oriko and the city with a massive spaceship loaded with hundreds of devastating weapons. Then the ship crashes into the bay because the weight of all the weaponry overtaxed the engines' ability to keep the ship flying. And because she and Gimlet spent all of their money buying those weapons in the first place, they're broke and stuck on Earth.
• Huge Schoolgirl: Oriko, Madoka, and Midori are all high-school aged though only the later two attend high school still.
• Incredible Shrinking Man: Dr. Sebastian also invented a shrinking drink, often used when Oriko needs to shrink back to normal in a hurry. It has also been used to shrink Stella to human size, and to shrink Oriko to mouse size to sneak into Madoka's room.
• Invulnerable Civilians: Everyone in Oriko's city wears a special protective suit nearly 24/7, which, given the frequency of giantess-sized antics from Oriko alone (never mind the sudden and destructive appearance of Invaders) is rather warranted.
• Just Following Orders: Midori initially came to Oriko's city under orders of her "onee-sama" to investigate the city's "power", but upon discovering that said power involves girls turning into (un)intentionally destructive giantesses… She's taking her time with it.
• Kaiju: Several Invaders are this to varying degrees of Ugly Cute to Eldritch Abomination.
• Large and in Charge: The de-facto leader of her city, Oriko is 180cm (a little under six feet) tall without heels. She later grows to 184cm. There's also the fact that she can, and will frequently, end up growing to giantess-size at any given opportunity. Inverted in the case of Madoka who is in charge of Oriko's Secret Service is 145cm, or a little over four feet, tall.
• Little Bit Beastly: Stella, being an Alien Invader, has a devilish tail and clover-leaf shaped pupils.
• Lonely Rich Kid: Oriko is a bit of a downplayed version as she happily filled her life with devotion to her city, but it's very clear that she had no actual peers while growing up. As a result, she tends to get overly enthusiastic about bonding with people, like shrinking down to sneak into Madoka's room or making Nakano her "little bro" for a day.
• Magic Pants: Averted… for the most part. Thanks to Dr. Sebastian, Oriko and co. typically wear clothing that grows with them. Not to say there aren’t instances when they AREN’T wearing them however…
• Marshmallow Hell: Nakano becomes the victim of this in Chapter 60 when he tries to meet Oriko. First is when he inadvertently sets off the intruder alarm and lands face-first into Midori's chest. It happens again when Oriko steps out of her shower.
• Mighty Glacier: Sebastian almost never uses the growth drink himself, because when he does he not only grows big enough to dwarf a giant Oriko, but he instantly puts back on all of the weight he had when he was a NEET. As a result, he can only move very sluggishly in this state, but is able to defeat Invaders by pinning them under his bulk.
• Missing Mom: Oriko's mother left to parts unknown shortly after giving birth. Whenever the plot turns serious it tends to revolve around the mystery of where she's gone.
• Moses in the Bulrushes: Stella's backstory is that Gimlet found her as an infant in a capsule aboard an abandoned spaceship he'd been looting.
• Ms. Fanservice: Given the cast consists of a lot of lovely ladies, it’s to be expected really.
  • Oriko is a tall young woman with an ample bust who is often the victim of both unwitting and intentional gigantification. She can and has stripped off her clothes, notably her shirt to snuff out a building fire, if it means helping her city in some way.
  • Madoka, while shorter and less buxom than Oriko, has this happen to her on more than one occasion. More than a few panels are dedicated towards her butt and legs.
  • Stella wears a two-piece outfit with short-shorts. Unlike Oriko, she is naturally gigantic and more than a few panels show off the fact that she is.
  • Midori was this in spades in her initial appearance and subsequent gigantifications. Her daydreams of being a giantess often have her in torn clothes if not outright nude.
• Nice Job Breaking It, Hero: Oriko’s attempts at drawing the attention of her mother, or at least garnering the attention of Invaders who might know of her and where she is, typically results in a far deadlier Invader coming to attack her city.
• Noblesse Oblige: While not technically nobility, Oriko's ownership of the city makes it a Distinction Without a Difference. She is also typically the first line of defense against Invaders, as well as working long hours to personally manage the city's administration.
• Oh, Crap!: Oriko’s reaction whenever she realizes she’s UNINTENTIONALLY growing into a giantess. That and whenever an Invader is attacking her city.
• Ojou: Oriko of course, with it being right there in the title. Though she has quite a few quirks that make her a bit of an atypical example.
  • Oriko B, a version of Oriko from a parallel universe, plays the trope straighter, albeit still comedically. Where Oriko is a Spoiled Sweet Action Girl who lives to dote on the people in her city, Oriko B presents herself as a Proper Lady while also being something of a Spoiled Brat who doesn't do anything herself, yet craves the adoration of everyone around her. Especially her universe's Sebastian.
• One Nation Under Copyright: The setting seems to run on a sort of corporate feudalism where zaibatsus own and run entire cities. With the overall light-hearted tone of the series, this is mostly shown in a positive light since Oriko is utterly devoted to the safety and happiness of the people in her city.
• Only Sane Woman: Madoka is the only rational-minded member of the team.
  • Oriko B. Fujidou may be even more a straight woman than Madoka (who occasionally shows an eccentric side) as her Ojou mannerisms are not nearly as extravagant as her counterpart and she's repeatedly befuddled by the nonsense the main cast gets into.
• Our Giants Are Bigger: The Invaders come in a variety of sizes just as the girls, notably Oriko, can grow to be a bit smaller than a skyscraper to large enough to hold the entire city in their arms.
• Panty Shot: Frequently with Oriko and Madoka especially, thought not always when the two are giantess-sized.
• Person of Mass Destruction: Aside from some of the Invaders being this in spades, any of the girls can and will be this when they turn into giantesses. Particularly hilarious in Oriko’s case as she has caused more damage to her precious city than some of the Invaders have.
• Police Are Useless: Rather, the police are entirely unnecessary as it is quite apparent the only kind of trouble that Oriko’s city faces is those of the Invaders.
• Reality Warper: META is one of the Eight Worlds who has cosmic knowledge about the events of the series and is a huge fan of ''Giant Ojou-Sama''. She appears before Oriko and Co. to celebrate the upcoming 100th Chapter and urges them all to get off their butts and get to finding Oriko's mom already. When she starts to get fed up with the crew she starts growing outside of the panel and devours the page, grumpily declaring that the series is over now while she's on top of the next-chapter preview.
• Scenery Censor: Subverted. The ONLY time this has come into effect is during instances of actual nudity, notably in the case of Midori who grew so large that CLOUDS were able to cover her exposed chest.
• Sensible Heroes, Skimpy Villains: Oriko's usual outfit is fairly conservative — a buttoned-up blouse; short, pleated skirt; and black stockings. Stella, on the other hand, is scantily clad in a bustier, short pants and visible thong straps.
• Sizeshifter: Though not without the use of a special energy drink, the girls can grow to varying sizes from amazon to absolutely titanic.
• Slime Girl: Penelope, an artificial life form created by Dr. Sebas.
• Space Pirate: Gimlet's job before he ended up as Stella's caregiver.
• Splash Panel: The manga is filled with them either in the form of single-panel pages to two-page spreads showing off the full scale of the girls when they’re in giantess-mode.
• Spoiled Sweet: Oriko grew up insanely wealthy and privileged, to the point where she was given an entire city when she was only four years old. However, she takes her role very seriously and prioritizes the safety and happiness of the citizenry above all else. She is also very friendly toward anyone who doesn't present themselves as a threat to her city, regardless of wealth or status.
• Statuesque Stunner: At normal size, Oriko is 180cm tall (slightly under 6'0"). After a growth spurt she's 184 cm (slight over 6'0).
• Stupid Sexy Flanders: Gimlet, of all characters, in chapter 69.
• Suggestive Collision: Somehow, Nakano Giraffe seems to get drawn into these situations almost every time he appears. Thankfully, (with his youth likely being a factor) this doesn't cause the girls to go into a Pervert Revenge Mode.
• Surprisingly Realistic Outcome: Several instances throughout the manga, particularly during instances involving Oriko as a giantess, i.e. her gaining a bit of weight at normal size results in her being too heavy for the roads of her city to support when she goes giantess.
• Teens Are Monsters: Midori gets REALLY excited at the mere IDEA of turning into a destructive giantess.
• Token Evil Teammate: Midori is this to the rest of the group, being much more excited by the power trip of being a giantess and secretly working to steal the “power” that the Fujidou group holds. Once the cat is out of the bag she quickly reconciles with Oriko and becomes a legitimate friend alongside her sister.
• Universally Beloved Leader: While she does make some mistakes that lead to the destruction of several buildings and more besides, Oriko is greatly loved by the citizens of her city.
• Wardrobe Malfunction: Particularly when one of the girls is wearing regular clothes and not one of the special stretchable ones made by Dr. Sebastian.
• When He Smiles: Gimlet sports a Cheshire Cat Grin ninety-percent of the time, but his rare genuine smile is a thing to behold. Sebastian B also gets such a moment.
• Younger Than They Look: It turns out that Stella is only twelve earth years old.
