Tropes for individual Infinite Stratos characters go here. Any contributions are appreciated.Most of the characters are in the same class; first year high school students (10th grade, 15 or 16 years old).Unmarked spoilers ahead.
Season 2 Episode 2 has him and Tatenashi in a judo match; after getting curbstomped by her for a while, he manages to grab her outfit, but inadvertedly pulls it open in the process revealing her ample chest. Cue Pervert Revenge Mode.
Book Dumb: Very bad when it comes to theoretical application, such as the mechanics of firing an IS-outfitted gun. This is why Chifuyu encourages him to simply stick to close-range combat. This is more of him being generally unfamiliar with anything IS-related than him being dumb.
Butt Monkey: Get's beaten up or insulted by his harem and sister, usually for being stupid, on a near regular basis.
Character Tics: He has a habit of clenching and relaxing his left hand when anxious (a reference to Shinji Ikari, who had the same habit). His sister has actually taken note of this, and explains that whenever the tic shows up in combat, it's a sign that he's about to do something reckless and stupid.
Class Representative: For Class 1-1. Cecilia originally won it by way of a duel, but later cedes the position to him.
Clueless Chick Magnet: Most of the time, though at least he knows of the affections of Charlotte and Laura toward him — after all, the former gave him a naked hug during their time at the hot bath; the latter gave him a kiss and later snuck naked onto his bed.
Crippling Overspecialisation: Played with — the Yukihira Type-2 is his only weapon, leaving Ichika crippled in ranged combat. When he notes this, Chifuyu points out that it'd be extremely hard for the inexperienced Ichika to learn the complex mechanics behind firing an IS-outfitted ranged weapon, advising him to instead perfect his melee skills such that he won't need long-range firepower anymore... just like how Chifuyu won the 1st Mondo Grosso Tournament.
That all changes, Mid-Season Upgrade-style when Byakkushiki second-shifted into the Setsura to save his life giving him a powerful Beam Cannon & Shield combo weapon.
Custom Uniform: Justified since he is the only male who can pilot an IS unit in the all-female academy.
His IS, particularly the Setsura, is also this to Shinn's Destiny Gundam.
Falling into the Cockpit: Averts the usual basics of this trope. During his high school entrance exam, he wandered into a storage room, where he discovered he could operate an IS upon touching one. Come Episode 1, he's already used ISs a few times.
The Fettered: Ichika never backs down on a promise he makes, and he draws strength from his need to protect his friends and family. Also, his talks with Charles (Charlotte) and Laura about his decision to protect them cause them to fall in love with him.
Charlotte: Sometimes I think you're doing this on purpose.
House Husband: Has the qualities of one, as lampshaded by his sister to his "girlfriends".
I Am Not Left-Handed: During his duel with Cecilia, he gets caught by missiles after destroying her drones. After the resulting Smoke Shield clears, it turns out he survived due to his IS upgrading and optimizing itself at the last second. Right then, Cecilia realizes that Ichika had been holding her off with his IS's default settings.
Cast from Hit Points/One-Hit Kill: The Reiraku Byakuya one-off ability, where the Yukihira Type-2 casts away the IS's shield energy for a shield-nullifying attack, powerful enough to force an opposing IS to activate its Absolute Defense, and thus ending the match in his favor. Its main drawback is the Byakushiki's low Shield Energy reserves and its limitation to said weapon.
Real Men Wear Pink: As Chifuyu described him, Ichika is great at cooking, house chores, and giving massages. Dude is destined to be the perfect house husband. In the OVA between Seasons 1 and 2, Charlotte even has a brief fantasy about how he'd make an excellent husband.
Running Gag: Every single time he's about to deal a finishing blow, his Byakushiki's energy always seems to run out at the worst possible time.
Sharp-Dressed Man: When he is late for a dinner with Houki in Volume 7, she is about to blast him for it until she turns around. The sight of him in a tuxedo makes her forget what she was about to say.
Unlucky Everydude: Ichika is very uncomfortable being the only guy in what is essentially an all-girls academy, leading to a number of awkward situations. Nevertheless he's not a complete pushover — especially towards Houki, who even hit him once, but he still got up and didn't let it faze him (and he even was the one who dragged her out to lunch by the hand, rather than the other way around), making him somewhat a subversion. However, he was tossed in harm's way after the reveal of the IS, first being kidnapped before he knew he was an IS pilot and now a target of terrorist attacks because they want his IS core.
Ichika's childhood friend ever since they're little kids. Although she moved away during their grade school years (due to tight security surrounding her older sister Tabane, chief developer of the IS, and her family), he still remembers a lot about her, and is happy that they're in the same class. Due to an extreme coincidence, they also end up sharing a dorm room, though Ichika doesn't see any harm in this. Later, Charles Dunois gets paired up with him, but Houki still keeps close contact with her old friend.
Clingy Jealous Girl: While initially hostile towards Ichika, when a senior offered to teach him on the IS, she immediately declines the offer for him. She also told him that if she won the championship tournament he will date her, which gossip blew out of proportion into a winner-take-Ichika tourney.
Cute Bruiser: She trained in kendo prior to the introduction of the IS suits, and her IS suit is melee oriented.
D-Cup Distress: While showering in the first episode of season 2, she seems to lament that her breasts have gotten bigger. Ichika definitely takes notice of it when she hastily meets him at her door a few moments later.
Invulnerable Knuckles: In the seventh episode of the second season, she gets to do a photo shoot & a joint interview with Ichika. She is so excited at the prospect that while in the dressing room of the studio, she starts punching her locker door while psyching herself up mentally. She ends up punching the locker door off its hinges. Meanwhile, her hand is perfectly fine.
Irony: Her sister created the IS but she doesn't get her own personal IS until the story is well underway.
But by the time she got her hands on the Aka Tsubaki, what a monster of an IS it is.
Parental Abandonment: Became part of a protection program which requires constant relocation due to Tabane's critical importance, and has since hated Tabane for affecting her family life and relationship with Ichika.
Unskilled, but Strong: Akatsubaki is a 4th-generation Super Prototype and the most powerful IS in existence. However, she's not a skilled pilot, so she can only be as powerful as the rest of Ichika's girls.
She seemed to have grown out of this trope in season 2: while Tatenashi was conducting a diagnostics test on her, she found out that Houki already qualifies as a Class S IS pilot. The former credits Tabane's involvement for her sister's sudden increase in ranking.
Official representative of the United Kingdom for the IS Academy. Although tension initially sparked between her and Ichika due to the latter's lack of knowledge about her impressive history, she warms up to him after he almost defeats her in a duel.
Attack Drone: Her Blue Tears has four of them, all of which shoot lasers.
Beam Spam: All but one of the Blue Tears' weapon systems are beam-type weapons. In fact, Blue Tears was designed from the ground up as a test bed for IS-carried beam weapons.
British Stuffiness: Her vocabulary in the original Japanese version is completely formal in its prefixes, suffixes and idioms; free of slang and other "vulgar" syntax. In other words, vocabulary spoken by stereotypically uptight and overly polite British nobility.
Cannot Spit It Out: Like Rin, has some trouble expressing her "feelings" for Ichika, despite being a bit of a tease herself.
Class Representative: She won the duel for the position against Ichika (simply because his IS ran out of shield energy just as he's about to deal the finishing blow), but nevertheless cedes her position to him.
Clingy Jealous Girl: While she hated Ichika initially, after nearly beating her in a duel, she became very friendly to him, and hates it when the other girls get close to him, particularly his two childhood friends.
Season 2 shows how her lack of common sense is a major cause of her horrendous cooking skills. While teaching her how to cook, Houki, Charlotte and the latter's roommate, Laura, all get sick from her attempts to make the food look better. Later, when Rin to teaches her how to make sweet & sour pork, Cecilia ends up blowing the latter's room up, as upon hearing Rin stating that Chinese cooking is all about "firepower", Cecilia decides to use her IS's laser.
Mid-Season Upgrade: There was a mention of a Strike Gunner high-speed package for her personal IS, just before their encounter with the Silver Gospel. It is unknown if she actually made use of it during the last battle...
Oh Crap: Upon seeing the Silent Zephyrs in episode 4 of season 2. Especially since the Silent Zephyrs was originally known as "Blue Tears Mk. II", basically Cecilia's IS Suit, but better in pretty much every way.
Ojou: Makes a big point of her noble birth and upbringing.
Seiza Squirm: Ichika even lampshades it when he sees her discomfort, asking why didn't she sit at a table instead. She refuses to, having won said spot next to him from the other girls in a game they played earlier.
Representative of China for the IS Academy and Class 1-2 Representative. She and Ichika were friends since grade school, some time after Houki left. They have fond memories of eating together in her family's restaurant, though it seems that Ichika doesn't remember things quite the same way Rin does...
A-Cup Angst: Never ever say to her face that she's flat-chested. In episode 5 of season 2, she punches the TV screen while watching Charlotte with Ichika, after the screen pauses on Charl's chest. She also angrily accuses him of staring at the other girl's boobs later on after Tatenashi steals her outfit to tease Ichika. The latter only adds fuel to the fire by saying Rin's outfit is a bit tight around the chest.
Childhood Marriage Promise: She made a promise with Ichika in which she'd treat him to food everyday if she got better at cooking (the implication being that they'd get married). Ichika, ever Oblivious to Love, took her words literally.
Child Soldier: In episode 1 of season 2, Rin mentions having been given sniper training just like Laura, when at a shooting gallery stand.
Genki Girl: Upbeat and energetic in disposition; disturbingly enough, even when she is angry enough to want to kill Ichika she is upbeat and happy.
Genre Savvy: The only one out of Ichika's harem to recognize just how much of a Lethal Chef Cecilia is. Thus, when Cecilia ropes her into teaching her how to cook, Ling makes sure to monitor everything Cecilia does while cooking, which Houki & Charlotte made the mistake of not doing.
Parental Abandonment: Her parents divorced due to differences, and the restaurant Ichika usually visits had closed down, forcing her to return to China, where she was scouted as an IS pilot. The first manga series showed that she was living with her uncle prior to enrolling in the IS academy, but even he didn't seem to be home very often because of his duties as a People's Liberation Army officer.
Tsundere: Swings between Type A and B, but such trait is not that much given emphasis.
Yandere: Busting through a wall and attempting to kill Ichika after Charlotte admits to her true gender (with most of the school knowing that she and Ichika took a bath together the previous day) counts as this. She also seems to have no qualms about hitting Ichika with her IS weapons even when he's unarmed.
Then there's this conversation between her and Cecilia while peeping at Ichika and Charlotte going shopping together.
Rin: Are they holding hands? Cecilia: Yes. Rin: "Ah, then it wasn't an illusion or a daydream. [Rin summons her Shenlong's right arm part] Rin: Let's kill them!
Zettai Ryouiki: Grade C in her uniform (see picture above), Grade S in her IS pilot suit.
Beware the Nice Ones: Is the kindest, sweetest girl you'll ever meet, with the smile of an angel◊. Just don't piss her off (or cheat on her), lest her smile will turn into that of the Angel of Death◊.
Bifauxnen : When she was forced to don a male persona, Charlotte can pass for a kindly handsome (if effeminate) boy who can set girls swooning with love. To drive the point home, when being requested to work as a waitress at a café, the owner decides to give her a butler outfit instead of a maid costume, stating she looks better in the former, despite being aware that Charlotte's a girl.
Bishie Sparkle: During her first introduction to the class as Charles.
Again when temporarily acting as a waitress in a butler outfit.
Bokukko: Her training to use the polite-masculine pronoun "boku" to refer to herself in Japanese stuck, even after she no longer has to maintain a male facade.
Clingy Jealous Girl: For all her kindness, she definitely is one, and willing to join the other girls' jealous antics.
Covert Pervert: A little bit. For example, he changes clothes in the same room as Ichika even when there's really no reason to. To the surprise of absolutely no one, Doujinshi took this and ran with it.
At least one doujin was written by the author (technically making this semi-canon), involving a... colorfuldaydream.
Dangerously-Short Skirt: While her school uniform skirt isn't really that short, in Season 2 Episode 6, a malfunction in her IS Suit somehow "turns off" the Magic Pants function (where an IS user returns to wearing the clothes she was before using her IS Suit). Fortunately, it only seems to affect a single article of clothing. Unfortunately, said article of clothing is her underwear. Even more unfortunately, any time she tries to put on another pair, it dissolves into energy (like her IS Suit does when she isn't using it).
Disappeared Dad: She only got to see her dad for the first time shortly before attending the Academy.
Hidden Buxom: As Charles, she wears something akin to a girdle to suppress her breasts.
Hyperspace Arsenal: Her Rafale Revive Custom II isn't nearly as fast or powerful as other personal ISs, but has a massive capacity for weapons and equipment specific for any situation. Normal ISs can carry around two or three different weapons. Rafale Revive II can carry over twenty, and he can also unlock their access for other IS users.
I'm Taking Her Home with Me!: So gentle, sweet, cuddly and adorable that this is the reaction she provokes from fans of both sexes, on both sides of the fourth wall.
Lovely Angels: With Laura when stopping a bunch of robbers in a restaurant.
Missing Mom: Her mother has already passed away before her introduction.
The Mole: She was originally sent to gather data on Ichika for her father's company to collect. Of course, once she was found out she may risk imprisonment, but Ichika assures her that her stay at the Academy would at least give her some sort of asylum.
Nice Girl : Gentle, polite, sweet-tempered and kind to a fault, Charlotte is the only girl of the initial-five harem who is not a violent-tempered, self-centered, emotionally-insincere and domineering Tsundere.
Noodle Incident: Ichika stripping Charlotte of her panties while trying not to look at her while changing together in their room. The DVD releases rectified it, showing that when Ichika heard her fall to her knees in a very awkward position while changing, he was about to stop her from letting out a scream. Unfortunately, he stumbled as well and accidentally grabbed her panties in the process.
Proper Lady: The sweetest, gentlest and nicest girl of the main cast, who ironically still uses the masculine profile of "boku" even in private with Ichika, the only time it's safe to be a real girl (at least until she finally comes out of her shell at the end of Episode 8). Justified since her father had her memorize the masculine dialogue.
Quick Draw: Her IS utilizes the Rapid Switch ability to draw out weapons at a faster rate.
Shipper on Deck: Is actively encouraging Laura to get closer to Ichika. May have something to do with the fact that unlike her, who at least knows her parents, Laura is an artificial human who knows next to nothing of such concepts as love or compassion (except maybe that specific "no woman gets left behind" type).
(After Ichika almost kissed Houki) "Ichika, what are you doing?"
Tsundere: A Type B like Houki and Cecilia, only a bit more subtle. The only time when her harsh side comes out is when Ichika is being particularly thick or when she gets extremely jealous.
Unsettling Gender-Reveal: To Ichika on Episode 5, and three episodes later, to the entire class via Yamada-sensei. Obviously some girls (especiallyLingyin) didn't take the implications well, especially considering it was known to everyone that she (as Charles) shared the public bath with Ichika the previous day.
Weak, but Skilled: Rafale Revive Custom II is a heavily modified 2nd-generation mass production IS. However, her skill allows her to keep up with the rest of the main cast, all of whom use 3rd-generation (4th-generation in Ichika's and Houki's case) prototypes upwards.
German representative and Captain of its military IS corps Schwarzer Hase ("Black Hares"). Chifuyu used to train her during the former's time in Germany, and initially despised Ichika for being too weak and causing Chifuyu's early retirement.
Actor Allusion: Her eyepatch is on the left eye instead of the right and doesn't use knives, perhaps to avoid making her look and sound any more like Cinque than she already does. In the second season, her knives start seeing a lot more use.
In the dub, it's apparently changed to resemble another eyepatch-wearing Tyke Bomb.
Adorkable: Post-meltdown. Her lack of social skills make almost any social interaction awkwardly cute.
Artificial Human: She was grown in a vat and genetically engineered to be the ultimate soldier.
Awesome, but Impractical: Her Schwarzer Regen's Active Inertia Canceller (AIC) can block any attack, beam-based or not, including a high-powered shot from Rin's Impact Cannons. The catch — it relies on Laura's concentration abilities, making her susceptible to multiple enemies.
It may have worked during her match with Cecilia and Rin, as both went long-range... but not so much with Ichika and Charles, who threw her off-guard by combining melee and long-range.
The Berserker: Her Schwarzer Regen's Valkyrie Trace (VT) System was meant to increase an IS's performance by mimicking previous Mondo Grosso champions (e.g. Chifuyu). However it went rogue due to Laura's brief mental breakdown upon realizing that Ichika and Charlotte exploited her AIC's weakness and turned the tide of the battle against her. No wonder research, development and application of the VT System is strictly banned.
Child Soldier: Segments of it can be seen in episode 8 of season 1, when she has a Flash Back of her training days back in Germany. She also explicitly states that she's in the German Army's IS corps and more or less asks them for advice, such as what to wear at the beach.
Clingy Jealous Girl: Normally averted. When she sees Ichika and Charlotte out on a date, she just decides to join them (though Rin and Cecilia stop her). Played straight when she sees him Almost Kiss another girl, though.
Laura: You're not paying enough attention to being my wife!
In the first episode for season 2, she invites him out to a pool date, only to get upset at him when he suggests inviting the other girls. Then in episode 2 of season 2, she walks in on Tatenashi forcing Ichika's head down in a Lap Pillow. She immediately summons one of her IS blades, and attempts to attack him with it, only for Tatenashi to deflect it effortlessly with her iron fan.
Defrosting Ice Queen: More like having gasoline poured all over her and set alight in a single episode.
Expy: Hmmn... A female super soldier with silver-gray(-ish) hair and initially a cold shoulder... Now where have we seen this before? Also to note, she also has a gold eye, much like one of the main characters from the same series.
As to her IS, the setup of its rail cannon is evocative of the Throne Eins from the same series.
Fangirl: Manages to stand out in a school filled with Chifuyu fangirls.
First Kiss: She steals Ichika's first kiss. While still onboard her IS. In front of the entire class.
Flawed Prototype: Chloe Chronicle refers to her as "incomplete," whatever that means.
Germanic Efficiency: She is raised first and foremost as warrior, a duty she excels in... ...at the cost of being taught none of the skills essential to being a normal girl, like making friends or understanding the concept of what a marriage is.
Knife Nut: Seems to be her Weapon of Choice apart from her IS. She wields some in season 2 during the Cinderella play, and seems rather good with them. Then later we see she has an entire locker full of them! Fortunately they're all properly secured in holsters.
Large Ham: Interestingly, she is probably the biggest ham in the show, second only to Tabane Shinonono. Witness, for instance, her holding up a pair of bloomers in the second season as if they were some kind of priceless treasure.
Lovely Angels: With Charlotte when stopping a bunch of robbers in a restaurant.
Love Redeems: So much after her defeat, that she took the initiative and planted a kiss herself.
Madness Mantra: In Volume 8, the false Ichika in her World Purge fantasy devolves into repeatedly telling her "Do your best" which extends to "Do your best to fight on & kill." The fantasy is hinted to be a coverup for her insecurities in being a living weapon.
Megaton Punch: Gives one to Ichika (with her IS's right arm deployed) in season 2 episode 6, after Ichika made a favorable comment about her eyes which got her all flustered.
Mid-Season Upgrade: Her IS gets a long-range artillery set-up for its main cannon (complete with recoil dampers) for their counterattack against the Silver Gospel.
Clarissa strikes again in the second season when she advises Laura to pick out an excellent pair of striped panties to flash Ichika with. Cue Laura immediately making finding a pair of hot stripes panties her top priority, to the point where she shoves a striped panties catalogue in Ichika's face and asks which one he likes best.
She Cleans Up Nicely: She laments that she's not attractive to men, as evidenced by Ichika's apparent lack of interest in her. When she's wearing fairly normal clothing, such as her swimsuit in episode 9 of the first season, or a regular dress in episode 1 of season 2, she does look pretty. Some other shoppers in the latter example even take pictures of her and Charlotte after she nearly trips wearing high heels for the first time.
(To Ichika, after having given him a Forceful Kiss) I hereby declare you as my wife! It has been set in stone; I will not accept objections!
What Beautiful Eyes: Ichika certainly seems to think so after the second time he gets to see her without her eye patch on. Unfortunately for him, this got her very flustered, to the point that she threw a Megaton Punch on him.
Russian Cadet Representative to the IS Academy (though apparently half-Japanese) and currently the strongest IS user in the Academy, warranting her the position of Student Council President. She's the pilot of the third-generation IS, Mysterious Lady.
The Ace: Good at pretty anything she does on screen.
Bodyguard Crush: For Ichika, unto whom she was temporarily assigned to protect after the Silver Gospel incident.
Boobs of Steel: The best IS pilot in the academy, and one of the bustiest girls in the series. She's actually second in size to Houki and is mildly put off by that... for about ten seconds before going back to her cheerful self.
But Not Too Foreign: Implied to be half-Japanese — in fact, her name is written in kanji instead of katakana. The light novels suggest that ethnically, she is fully Japanese but she simply has Russian citizenship.
Cool Big Sis: Affectionately caring and kind, Tatenashi wants nothing more than for her juniors to have a fun and happy childhood; something (much to her regret) she failed to give to her own little sister.
Drill Sergeant Nasty: Puts Ichika into heavy training to shape him up, leaving him exausted afterwards.
Good Bad Girl: In stark contrast to every other girl in this franchise, Tatenashi is completely frank and comfortable with her sexuality, knows and openly-acknowledges that she is cute-and-sexy while enjoying every second of it. While she enjoys getting a rise out of chaste Sour Prudes like Ichika and Houki, she is ultimately too good-natured and kind to go beyond anything more than harmless teasing.
Green-Eyed Monster: In episode 8 of season 2, she admits to Ichika that she's a little jealous of his relationship with his sister Chifuyu. When Ichika wonders what she means, due to Chifuyu's constant sternness with him, Tatenashi tells him that it means she's at least looking out for him, unlike her own relationship with her sister Kanzashi.
Cast from Hit Points: Her IS's one-off ability, Lance of Mysteltainn works similarly to Reiraku Byakuya, in which the water-based nanomachines gets concentrated towards the tip of her lance for a sudden offensive boost, in exchange for a decrease in overall defense.
Lemony Narrator: Her narration of the Cinderella play in episode 3 of season 2, especially when Ichika tries to give his crown to Charlotte, only to have Tatenashi remotely shock him while claiming his own doubts are doing it due to the love of his country. note She told the girls without telling him that whoever gets his crown would get to be his roommate. Hence why he tried to just give it to Charlotte before Tatenashi stepped in
Rei Ayanami Expy: Red eyes, aquamarine hair, so she at least got the appearance, as well as the piloting skills. Subverted big time by her personality.
Sensual Slav: Sort of subverted since she's biologically half-Russian. Plays the "sensual" part straight towards Ichika, though.
Screw the Rules, I Make Them!: Used her position to become Ichika's new roommate. She also abuses this power to allow another girl to move in with him on the condition that they can take his crown during a play. Needless to say, every single one of the girls tries very hard to get it. And she conveniently neglected to tell Ichika...
The Tease: Which doesn't sit well to Ichika. Or Laura.
Troll: Part of her teasing act is to goad a reaction out of Ichika or his harem. There's also baiting the entire school to steal the crown that he is wearing in hopes of being his roommate, only to take the crown and deem herself the winner.
Berserk Button: For all her angst against her sister, Kanzashi loses it when she sees her sister lying defeated in episode 9 of season 2 by the unmanned IS suit. While it does enable her to defeat one of them, she used up all her energy, and another unmanned suit has easily taken care of Ichika, and throws him around while she watches helplessly.
Can't Catch Up: She tries to work on her own IS suit without help, but is unable to do it. She ends up reluctantly accepting help from Ichika and several of the other girls, but finds out that him being nice to her was simply because Tatenashi wanted to secretly help her build her suit. She doesn't take the revelation well when she overhears her sister talking to Ichika about it in episode 8 of season 2.
Custom Uniform: Looks more or less like the normal IS uniform, the only difference being the floral borders on the skirt edges and the unique-looking "side pods" (see pic above).
Defrosting Ice Queen: She is hostile towards Ichika at first, due to her IS suit being put on hold while one was built for him first, and refuses to be his partner for the tag-team tournament in season 2. However, due to his persistence, and saving her when her IS suit malfunctions during a test, she begins to reluctantly accept his help.
Sibling Rivalry: She doesn't really get along with her older sister, to the point that when Tatenashi asks Ichika to be Kanzashi's tag-team partner to better protect her, she asks him to make no mention of her. She seems to get over this at the end of episode 9 of season 2, when Tatenashi tells her that she never looked at her sister that way, and always respected her abilities, and nearly died protecting her earlier.
Wave Motion Gun: Her IS has a couple of particle cannons mounted on her waist.
Ichika's 24-year-old sister and herself a retired IS ace, as well as head teacher of IS Academy's Class 1-1, where Ichika, Houki, Cecilia, Charles and Laura are placed. She gained popularity for her skill with a katana, with which she won the 1st Mondo Grosso Tournament, only to disappear after forefeiting her title defense at the 2nd Mondo Grosso to save the kidnapped Ichika. During her hiatus, she went to Germany to train IS pilots (one of which was Laura) as repayment for the German army's contribution to her rescue of Ichika.
Ace Pilot: She won the first world-wide tournament for IS pilots, and was the runner-up in the 2nd (only because she didn't show up for the match). Yet years later, she is still regarded as the best.
Aloof Big Sister: To Ichika, especially at the school where she doesn't believe in showing him favoritism despite him being the only male amongst an entire school of female pilots. The fact that she's a world class pilot and he didn't have any sort of preliminary training beforehand doesn't help either.
Subverted once in a while when she sees Ichika in real danger and she can't do anything about it. Usually she becomes even colder and aloof but she'll do things like pouring salt instead of sugar into her coffee or sport DeathGlares at no one in particular.
Asskicking Equals Authority: She won the first world-wide IS Tournament handily as Japan's Representative and is revered as one of, if not the best, IS pilot of all time. She is now a prominent teacher at the Infinite Stratos Academy and prior to that, became Germany's official IS instructor to their special IS squad for a year. When it comes to matters pertaining to the IS, even other instructors will take notes from her.
She invokes this to her students, who didn't think much of her co-instructor Maya Yamada, who was also a Representative Candidate in her day. She had Cecilia and Rin (both personal IS users) fight Yamada (who was also in an inferior suit) 2 on 1. They lose - badly.
Chifuyu:"Now you all know what your instructors are capable of. Knowing that, show them the proper respect."
Badass: If winning the 1st Mondo Grosso armed with nothing but a Laser Blade isn't badass enough, then what else?
To add to that, she is rumored to be the insanely strong IS pilot, 'The White Knight' who saved Japan when the country was being targeted for destruction by 'rogue' ICBMs years ago. Since Tabane unveiled the Infinite Stratos technology ten years ago, that would have made her age 14 at the time.
Badass Normal: First on-screen act she performs is wielding a BFS made for an IS unit by itself and stops Laura's energy blade with ease.
In Volume 8, she takes on an IS on foot with a special anti-personnel body suit and six modified katanas. Granted, none of her attacks managed to really damage the enemy IS, the pilot couldn't even touch her until the very end. Also her Badass Boast just prior to taking on the enemy IS pilot is its own awesome:
“Bring it on. You’re standing in front of the First-Generation's Brunhilde, the first woman to attain the title of "Strongest", so just focus entirely on fighting me, ordinary soldier.”
Big Sister Instinct: Her little brother is kidnapped!? Screw the Mondo Grosso title defense, time to save Ichika!
While it gives him no small amount of grief, she enrolled him into IS Academy to keep the storm of corporate and government recruiters off his back and where she can keep an eye on him. She also assigns him a high-level bodyguard when she thinks that someone will attempt to steal his IS' core - she was right. From the hints from her talks with Maya, she would have preferred to do it herself if not for her lack of an IS.
Also has hints of My Brother Is Off Limits — she's fully aware of Ichika's Unwanted Harem and their affections towards him, but she's making it clear she's not simply letting them have their way with him.
Even those she defeats end up swooning from her charisma and general badassery. When she finally freed a captured enemy IS pilot, the pilot hesitated to leave and even gave Chifuyu her personal contact number!
Rare due to her very professional demeanor but she is not as 'ice queen' as she once was and will occasionally tease her students. She did this with Cecilia, peeking at her 'erotic underwear' and attempted to do this with the girls by saying she wouldn't give up Ichika to them but they misinterpreted her meaning.
Also later on, when Ichika is given the task of taking his female classmate's measurements, she hands him a piece of cloth to use as a wrap over his eyes. He then discovers he can actually see through the fabric.
Genius Bruiser: While not at Tabane levels, one must assume that if she is able to correctly analyze and predict her opponent's equipment and purpose, their weapon aim and trajectory paths while keeping up the pressure on them using only a single melee blade, she is a very smart fighter. The info dump she hands to Ichika about some of the factors that go into an IS shooting battle has him slumped over in less than 30 seconds.
It only makes sense to learn how they fight and what factors into it so that she could come up with strategies to use against them.
Harem Nanny: In the anime, more or less... her duty as dorm warden makes sure she keeps Ichika's harem from going wild on her younger brother, for the most part.
Hot Teacher: Has received nothing but compliments about her model-like figure.
It Runs in the Family: Piloting an IS seems to be in the blood of an Orimura. Just ask Ichika. Or Madoka.
Masculine Girl, Feminine Boy: While Chifuyu is an in-universe Badass and is working full-time to support both herself and Ichika, she doesn't/can't cook or clean so Ichika takes care of the house and meals when they are home. Lampshaded to hell and back when his harem comes to visit and they see the Orimura siblings in their natural state.
Charlotte: What is up with these two?
Cecilia: They look a lot like a husband and his wife.
Onee-sama: Most said girls (particularly her fangirls) refer to her as this.
Rapunzel Hair: In certain moments that her hair is not tied up (particularly during the Beach Episode in season 1, and that moment where she was roped into wearing a maid outfit in season 2), it reaches down to her lower back.
Red Baron: She has two nicknames but only one of them is publicly known: Brunhilde, which she got for winning the 1st Mondo Grosso; the other, Shirokishi aka The WhiteKnight, would most likely cause an international incident if known.
This person in front of them now is completely different from the lawful and ridiculously strict 'Orimura-sensei', causing the girls to be dumbstruck, especially Laura, who continued to blink her eyes like mad as if she couldn't believe what she just saw.
Chifuyu: "Stop giving me that weird look! I'm an ordinary person, of course I would drink beer! Do I look like I drink machine oil?"
Tsundere: She has shades of this for Ichika, which has been vaguely hinted at in Season 1 but is clearly seen in Season 2. In episode 4 of the latter season, after she tells Yamada that she had Tatenashi become Ichika's roommate due to an unspecified threat against him, the latter asks if she wanted to have been in that position instead. Chifuyu develops a Luminescent Blush, then denies wanting to protect her brother herself.
There's also the matter of her dressing up as a maid for his birthday and the non-stop blush she sported through the entire thing, even more after he teases her a bit afterward.
During the class meeting for the school festival, she seems to be quite game with the "Pocky with Ichika" idea, much to his dissent.
Kawaiiko: Her behavior and appearance would indicate a bright and cheerful middle-school teenager were it not for her vocation as a teacher.
Meganekko: On top of being bespectacled, she possesses the adorable clumsiness characteristic of her stereotype.
Nice Girl: Has a disposition warm as a sunny afternoon and a winning smile that can stop wars (not to mention traffic)
Older than They Look: So bright, sweet and adorable she looks younger than her 15 year old students. Heck, in the first episode when she gets embarrassed in front of her class, the entire class Squees.
"Aww, she's so cute!!"
Retired Badass: Was a former Cadet Representative during her student days.
Sensei-chan: Is more of a cheerful and adorable big sister to her students than an authority-figure proper.
Zettai Ryouiki: Actually has a Grade C with her blouse and knee-high shoes. (See above pic)
Houki's older sister and inventor of the IS suits.
Action Girl: She claims that the only one who could match her physically is the resident Badass Chifuyu.
Badass Adorable: Casually beats down all 3 members of Phantom Task, including "M" in her Silent Zephyrus, ON FOOT. When she needs to be deadly, only Chifuyu is her match, and even then only barely.
Beware the Silly Ones: When several members of Phantom Task attempt to attack her in episode 10 of season 2, she largely keeps her Genki Girl persona. However, at one point, her face does change from a cheerful one to a much more serious look as she proceeds to dismantle Madoka's IS while the latter is still wearing it.
Dynamic Entry: Apparently her favorite method of crashing a party, but usually with a lot of noise (which subverts this trope's surprise element). One of her attempts was pacified by Chifuyu, with just one hand.
Face-Heel Turn: She decides to build an I.S. for Phantom Task after meeting Madoka Orimura.
Game Changer: This is a woman who invented a technology that changed the very nature of warfare.
Genki Girl: Always bright, always sunny and happy, always immature.
Hot Scientist: Has generous proportions that rival that of her little sister Houki's, accentuated by her choice of a revealing Cleavage Window blouse.
I'm Taking Her Home with Me!: She says this to Madoka after she sees the latter's uncanny resemblance to Chifuyu. Interestingly, while she refused to provide IS suits for Phantom Task, she was more than willing to make one for Madoka, who is part of said group.
Cecilia: I'm honored to meet so renowned a person! If you don't mind, would you take a look at my IS? Tabane: (in an ice-cold tone) Huh? Who the hell are you? I don't know any blondes. I was having such a fun reunion with Chi-chan and Ik-kun, and you just had to go and ruin it, huh? Get out of my face. Cecilia: Uh... um... Tabane:Shut up and go away.
Incredibly enough, the above exchange is noted to be an improvement in her social skills. Ordinarily, unless your last name is "Orimura" or "Shinonono", Tabane simply does not acknowledge your existence. At least she's actually responding to Cecilia above.
Adaptational Heroism: She is only this nasty in the orginal novels. The Anime on the other hand, opts to omit such unpleasantries, making her a completely sweet and goofy character instead.
The Volume 7 epilogue reveals that she is the one who keeps sending the unmanned Golem I.S. drones to attack the Academy! And it is solely so she can obtain real-world battle data about Houki. Never mind that she puts dozens of students' lives in real danger. The anime didn't adapt this scene but it's more than likely still canon.
Kawaiiko: Much older than most, but nevertheless extremely cute.
Large Ham: Much like Midori Sugiura, another beloved role of her actress Yukari Tamura, Tabane's brain is permanently stuck in the loud, theatrical and melodramatic world of a Power Rangers episode.
Let's Get Dangerous: She could tell her soup was spiked with a tranquilizer seemingly by just glancing at it (in the novel, she drank all the poisoned soup but it didn't affect her). She then made all 3 members of Phantom Task her bitch in less than 3 minutes. One of them had a handgun and one of them was in an IS. Tabane was armed with... a butter knife and fork. All this while still being the complete goofball she is, never losing that winning smile. She also tells them the only person capable of matching her speed and skills is Chifuyu.
Mad Scientist: Oh she's smart, yes. Connected to the world of reality and maturity? Not so much.
Nerves of Steel: When three of the Phantom Task members attack her, she never loses her composure or her Genki Girl persona, and absolutely floors all three of them with little more than a butter knife, a fork, and a couple of swift kicks.
The Nicknamer: She refers to Chifuyu as "Chi-chan," and Ichika as "Ik-kun." She also calls Madoka Orimura "Mado-chi."
No Indoor Voice: She's either on shouting mode or laughing mode, no exceptions.
Older than They Look: She invented the entire IS technology system over 10 years ago, and somehow still looks like an extremely cute girl who has just entered her twenties...
One of the Kids: She's quite childish compared to Houki, much to her and Chifuyu's chagrin. You could easily mistake her for Houki's younger sister.
Playful Hacker: Chifuyu hypothesizes that she may caused Silver Gospel's rampage just to help Houki's debut as a personal IS user.
Pop Cultured Badass: At the end of Volume 2 of the novels, her phone's custom ringtone for Chifuyu turns out to be the theme song to The Godfather. Another custom ringtone on her phone ( which is for calls from Houki) is a music track from the Japanese film The Yakuza Wives.
Rapid-Fire Typing: While adjusting her sister's new suit. With a holographic keyboard, no less.
Shout Out: In the anime, she makes a dramatic pointing pose reserved for a manly rousing speech, just to introduce her sister's own IS. The corresponding dialogue in the English dub sort of highlights this:
Dan's younger sister and a third-year junior high schoolgirl.
A-Cup Angst: Though in a subversion, she's actually got a decent bust. It still is played straight in the OVA, since her brother freaked out at the festival, asking people if they've seen a flat-chested, red-haired girl around.
Demoted to Extra: She actually appears quite frequently in the novels, making almost one appearance per volume, but the anime limited her screentime to only a few minutes in a single episode and the season 1 OVA.
Ancient Conspiracy: Not as ancient as most conspiracies, but the German army's best intelligence regarding them indicates Phantom Task was created sometime around the end of World War II, and that they have been active for at least 50 years.
Meaningful Name: The kanji for their name roughly translates to "Fallen Nation Textile Industries". They may have started as either a German or Japanese corporation providing civilian aid in the wake of the postwar Allied occupation.
N.G.O. Superpower: They are able to penetrate the security of multiple military bases around the world with very little effort and know about I.S. suits & weapons that don't even officially exist.
Oddly Small Organization: The anime & novels have only shown us three members of their group. In Volume 6 of the novels, the German army's intelligence indicates there is at least a Board of Directors & a Specialist group that comprises Phantom Task.
Realpolitik: The real reason why they have been able to keep stealing I.S. cores without any true backlash and stay hidden from public knowledge. As there is only a limited number of I.S. cores in existence, any country that announces they have lost one will immediately be at a disadvantage relative to other I.S.-equipped countries, which means that the thefts are never officially reported. In addition, the fact that a lone agent is able to compromise military security and single-handedly steal an I.S. is probably a big embarrassment for every targeted country's military, which provides further incentive to downplay the losses. The fact that the thefts are always conducted with zero fatalities likely means that the group is regarded as a lower-level threat than, say, terrorist groups like al-Qaida.
Secret War: They've been fighting the Sarashiki family for decades behind the shadows of international politics.
Would Hurt a Child: They were the ones who kidnapped Ichika during the second Mondo Grosso tournament.
A member of the secret organization Phantom Task and pilot of the experimental IS, Silent Zephyrs. She actually looks like a younger Chifuyu who blames Ichika for stealing her life, but later reveals that she only wants to kill Chifuyu.
Blood Knight: From what is known of her, she loves fighting.
Emotionless Girl: This is a facade she puts on, but the truth is that she is boiling with rage underneath her cool exterior. She just knows how to manage her emotions well. Mentioning the Orimuras is the best way to really press her Berserk Button.
Evil Doppelganger: Dead ringer for Chifuyu when she was younger. Goes even further since her new I.S. is Black Knight in contrast to Chifuyu's White Knight I.S.
Expy: She's a lot like an evil Inori, right down to the heavily-implied (in both series) being a clone of the main character's older sister. Probably an Actor Allusion as well, considering Ai Kayano also did that character.
Grand Theft Prototype: Steals the Silent Zephyrs from England, which she then uses personally afterwards.
Impossible Thief: She and Phantom Task specialize in stealing IS units from around the world. These are classified corporate and governmental items with dedicated security teams and IS guarding them - and they still manage to steal them.
She takes the art to nigh Badass levels when she breaks into a base to steal a highly classified IS alone. The anime showed her raiding a British military base to steal the Silent Zephyrs. She does it again in the novels when she raids an American base in the Pacific Northwest to steal the Silver Gospel, but is unsuccessful this time.
Know When to Fold 'Em: Her raid on the American base is cut short when Iris Calling appears in the Fang Quake I.S. Even though Madoka is sure her Silent Zephyrs could probably beat it in a one-on-one match, she also knows time wasted fighting it is time for more reinforcements to arrive, so she wisely retreats.
Mid-Season Upgrade: Her new I.S., Black Knight, debuts in the second-to-last episode, presumably built by Tabane.
Nerves of Steel: She's completely unfazed in the novels during one of Autumn's temper tantrums when she pins her to a wall and holds a knife to her eye after the failed attempt to steal the Byakushiki at the Cinderella play. Later, after her unauthorized assassination attempt on Ichika after his birthday party, Squall is the one unhappy with her and slams her against the ceiling with her I.S. Like before, Madoka barely reacts.
Removing the Rival: Sees Ichika as the one who stole her place in the world. And she almost did it the first time that they meet if it wasn't for Laura. Later flipped around when the object of her hatred turns out to not be Ichika, but Chifuyu. She even cuts her own face simply because it looks like Chifuyu's.
Spell My Name with an S: While the Light Novels and this TV Tropes page list her IS as "Silent Zephyrs", the anime used "Silent Zephyrus".
The Worf Effect: Her Silent Zephyrs suit, which for most of the season is extremely overpowered and outmatches everyone at the I.S. academy, is effortlessly torn to shreds by Tabane Shinonono with her bare hands.
Reiko "Autumn" Makigami
Voiced by: Yuka Nishigaki
A member of Phantom Task. She was tasked to steal the Byakushiki unit from Ichika.
Adaptation Name Change: Her cover identity's first name was "Ayako" in the novels, but it was "Reiko" in the anime.
Ax-Crazy: After she "saves" Ichika from the Cinderella play, she develops this look on her face.
Spared by the Adaptation: In the novel version of the episode 10 scene where Phantom Task tries to blackmail Tabane, Autumn was holding a knife to a hostage's throat. Tabane frees the hostage, breaks Autumn's arm, and stabs her in the lung with her own knife. We're not told if she gets up from that or not. While Autumn appears in the final 2 episodes of season 2, these are anime-original material. It's quite possible she might be dead in the novels continuity unless Volume 9 is released and she turns up again.
Spider People: Invokes this with her IS Arachne, which was built in the shape of a spider and has the pilot connected to where the thorax would be located. Combined with her psychotic personality and the fact that she would have succeeded if not for Tatenashi's interference, she was certainly making Spiders Are Scary true for Ichika.
Dramatic Irony: In Volume 7, Ichika is supposed to have dinner with Houki in a high-class restaurant using the vouchers he got for the interview/photoshoot. But he can't go in without a tuxedo. Seeing his dilemma, a beautiful woman appears and introduces herself as Ms. Meusel, and buys him a tuxedo as well as a bouquet of roses for Houki before sending him on his way. Before he leaves, she reveals her full name to him, and wishes "Orimura Ichika-kun" luck. Ichika wonders briefly how she knows his name but then dismisses it. (this scene didn't get animated). In season 2 episode 11, she graciously offers to take Ichika & Houki's picture. In both circumstances, nobody knows who she really is, only seeing her as a friendly stranger.
One Name Only: Her last name was only revealed in the novels. It's a spoiler for the scene it comes up in.
Pragmatic Villainy: She always places Madoka under non-lethal limitations when attacking military bases because if even a single soldier dies in these raids, it would trigger a much harsher response from the world's militaries against Phantom Task.
Tampering with Food and Drink: She spiked Tabane's soup with a sedative at their dinner, but Tabane caught on. It wasn't clear if she touched it in the anime, but in the novel version of that scene, she drank all the soup but wasn't affected by it.
Wham Line: The reveal of her last name is this in Volume 7.
With Friends Like These...: Autumn & M do not like each other, which means she has to more or less play referee when they get violent.
