Fan Fic / Infinite Stratos Prototype Spartan

Go To

"Okay Mickey, I need you with the Demoman to move up on the left side of the objective. Romeo, you need to go in with the Spy-"
Kira and his 'tactics training'

"Shut up. All OF YOU! You know, I'm not sure how many friends you've had, Orimura-sensei, but I know that when someone nearly kills two of my friends, they die by my hands."
Kira, Chapter 8, telling Chifuyu what happens when you mess with Kira's buddies.

Infinite Stratos: Prototype Spartan tells the story of Kira Orthun, the pilot of the IS Unit MJOLNIR, as he enters IS Academy, told from his perspective. The story mixes in elements of Halo while keeping in parts of Infinite Stratos, all the while adding new parts into it, somewhat expanding on the world of Infinite Stratos and how the world could've been affected with its introduction.

Even with the elements of Halo present, the author manages to keep Kira Orthun from being too overpowered considering how Halo: Combat Evolved took place past the 2500 year range, sticking with the rules of IS battles. The story includes some Alternative Character Interpretation, putting a few characters into a new light and exploring how one person can make a huge difference, and also delves deeper into how a super weapon for one gender can tip the equality of the sexes massively.


The story was published August 24th 2012.

As of December 15th, 2012, Season One (what the first season on the anime covered) has been completed.

Also, as of May 5th 2013, what the Light Novels cover (as Volume 8 had yet to be released) has been completed.

As of May 12th, 2013, Season Two has been completed.

The story was completed on August 24th, 2012, the author saying he had been aiming to complete the story in a year. The author also states that four omakes will be coming out, one of which has been completed.

Note: When referencing chapters, please use the fanfiction chapter numbers. (For example, Chapter 25 on the fanfiction site is Chapter 22 from Kira's point of view as the author does not label Season Openings/Finales, Flashbacks, and Holiday Specials with 'Chapter X')


This fic provides examples of the following tropes:

  • Adaptational Badass: Ichika is far more competent that his original counterpart.
  • Amazon Brigade: The base in Chapter 9 is full of women who know how to pilot all sorts of vehicles.
  • Armor-Piercing Question: Asked by Kira to Kaznashi.
    Kira: "I know you're scared, but just ask yourself, if you crawl away and hide, what happens to the people that you care for?"
  • Anti-Hero: Kira. He stays on the side of good, but slips into the other categories when his Berserk Button is pressed.
  • Augmented Reality: Done with One Hundred Percent Synchronization.
  • Badass Boast: Kira gets several.
  • Badass Crew: Wolf Team... and all the other Spartans.
  • Bash Brothers: Kira and Ichika
  • Battle in the Center of the Mind: The beginning of Chapter 13. Kira is in the part of his mind that E has taken up and faces himself, Persona 4 style.
  • Because You Were Nice to Me: Madoka's reason for betraying Phantom Task and coming back to Kira's side.
  • Better Than New: Kira in Chapter 1, who's about to die... and then comes back as a half-IS, half-man hybrid.
  • Beware the Nice Ones: Kira's normally a pretty polite person... until you make him snap. See Berserk Button below.
  • Berserk Button: You simply do not harm Shinonono Tabane if Kira is around.
    • Do not ever say that Kira is not normal.
    • Do not say that E is not human in front of Kira.
    • Do not treat Kira like a tool to be used.
  • Break the Cutie: No so much as 'cute' in Kira's case, but after Chapter 9, things take a turn for the worse.
  • Brick Joke: Used with Curse Cut Short.
  • Bridal Carry: Done by Kira to Kazanashi in Chapter 21... right before leaping out of a window.
  • Call-Back: Invoked by Ichika:
    "Kira?! What the hell are you doing?!" Romeo screamed as I limped forward, pushing Lopez aside. It's not giving the countersign…
    Ichika: Oh no.
    Cecilia: …What is it, Ichika-san?
    Ichika: Cecilia-san… you remember the first day of class, right?
    Cecilia: Hm…? Oh. OH…
  • Calling Your Attacks: Ichika seems fond of this at times.
  • Casual Danger Dialog
  • Cerebus Syndrome: End of Chapter 9 through Chapter 12.
    • Though it shifts back to its regular state of comedy by the end of Chapter 13, making it a bit of a Cerebus Rollercoaster.
    • However, with Season Three, it seems to be following this.
  • Character Development: Kira went from being overly paranoid and rather violent at times and over time becomes friendlier, then even manages to be able to accept the darker parts of himself.
  • Chekhov's Gun: Remember that thing that took up all of Kira's remaining Equalizer's all the way in the beginning? It's actually HyperDrive, a performance enhancer with a nasty time limit of five minute usage.
    • Also, at the beginning of Season Two Kira mentions he added a coin dispenser to his IS. Guess what he uses as a weapon later on.

  • *Cough* Snark *Cough*: Done by Madoka.
  • Covert Pervert: Madoka calls Houki out on this.
  • Crazy-Prepared: Overlaps somewhat with Zen Survivor.
    Kira: I don't train. I survive. There's no way to train for an ambush that kills your best friend. There's no way to train with how society sees you. There's no way to train for assassins and terrorists trying to kill you to remove the symbol of man's hope. But I prepare for the next time it could happen. Because I can.
  • Curse Cut Short: The end of Chapter 5
  • Cybernetics Eat Your Soul: Averted, since E becomes somewhat of a Morality Pet for Kira.
  • Damn You, Muscle Memory!: Kira is used to reloading, so even if his unit is capable of firing without the need to reload, he keeps the manual reloading setting on.

    • Kira was kidnapped and raped when he was roughly 12 or 13 years old
    • Killed someone right after breaking out of his prison
    • Then, later on, a good day turns horrible when the Russian Army comes in to invade.

  • Determinator: Ichika's Hot-Blooded attacks can still drill through Laura's AIC.
    • Chapter 12.5, even though he's been knocked out due to HyperDrive, Kira gets up and starts shooting at Silvero Gospel despite any injuries he has.
    • Subverted, since he still falls due to his injuries despite his determination.

    line break
    "Come back here and let me KILL YOU!"

  • HA HA HA— No: Combined with Incredibly Lame Pun.
  • Harem Genre: Deconstructed in the Season Two finale.
  • Heroic RRoD: Kira's HyperDrive. It boosts strength, reaction time, everything to make him a better fighter. It only last five minutes before he goes unconscious before it starts to negatively affect him.
  • Heroic Sacrifice: Kira pulls this off when Muesel is about to throw the world into chaos with rampaging Prototypes.
    • Subverted, in that he didn't really die, but rather just took him and Muesel elsewhere so she couldn't activate the program that would remove the limits on the Prototypes so they could cause mass destruction.
  • Hero with Bad Publicity: After Chapter 9, due to Kira's murderous rampage, it gives people against him more leverage and makes him seem like a monster.
  • Heterosexual Life-Partners: Kira and Ichika.
  • Hidden Depths: It's easy to see Kira as a stoic soldier that can kill in a heartbeat but in Chapter 22 he reveals that he's just as scared as anyone else, but he can't afford to show it because then everyone loses morale and they all lose. He also mentions that he's fighting for those he cares for, not just for the sake of fighting.

  • I Just Want to Have Friends: During the flashback chapters it's revealed that Kira just wanted someone to stand with him as a friend.
    • When Kira and Rei talk with each other.
    "I don't care!" Rei snapped, "Kira, I don't care if you don't want my pity, my apologies… but I do know one thing. I will always stand by you, no matter what has happened to you in the past!"
    And for the first time in a while, Kira wept tears of joy as he embraced Rei, "Thank you… I've always wanted to hear that from someone other than my closest friends that I had before all of that. Now… you need to hear the full story… so go back to E, and hear her out, will you? And don't blame Tabane, since she's what gave me… the opportunity to be what I am."
    "Yes, of course." Rei gave him one last squeeze… and before she left, pecked him on the cheek before skittering away, blushing madly.

  • More Dakka: Rei. She has multiple Hurricane Bolters on her IS Unit.
  • Murphy's Law: Kira makes references to it in the beginning.
  • Never Be Hurt Again: From the events of Chapter 11 and 12, it's shown that Kira adopted a more violent sort of personality in order to cope with his rape.

    Kira: "Look, just because I don't show it doesn't mean I'm not. But I'm going to tell you the truth right now. We're up against an unknown enemy that has far superior technology than what we've previously encountered, a giant crawler is making its way up to the school right now and is wrecking the town, so I'm pretty much shitting my pants brown right now. But I can't afford to show it because then everyone loses. I have to force myself to be brave or at least look brave, because there is no such thing as a flawless person, let alone me of all people. I know you're scared, but just ask yourself, if you crawl away and hide, what happens to the people that you care for?"

  • Suspiciously Specific Denial: Kira most definitely does not have a complex for older woman. Nope.
    Kira, after E teases him about Tabane: I do not have an older women complex nor do I possess a fetish for them!
  • Switching P.O.V.: Changes from Chapter 10 through 12, but comes back at the end of 12.
    • Fridge Brilliance: The titles of every chapter where it's Kira's POV all have "The Prototype" in them but chapters that aren't entirely his POV don't.
  • Take a Third Option: When faced with either completing the mission or his morals... Kira decides to pick both.

    Kira:"Ah, technically we are military, but we don't serve a country. We're loyal to Tabane, who gave us this chance. Ain't that right, Wolf Team?"
    Wolf Team:"OOH-RAH!"
    Kira:"Also, we're like brothers. We steal from each other, fight one another, steal each other's girl and laugh about it, but when there's something that threatens or harms one of us, it does so to all of us." I glared at her, "I know I look like some mascot up here, but trust me, I have seen things that I should never have seen."
    • Delivers another one in Chapter 9:
    Kira: "Look, all you morons! I knew fair and well that coming here could result in my death or worse." I started my speech, "But did I run away? No! Did I cry in a corner? Hell no! I came down here ready to fight my way out if I needed to! Hell, I've been in a position you were in, but the difference between all of you and myself at the moment is that I GOT UP AND STARTED FIGHTING AGAIN! Are you just going to cry about the fate that was handed to you, or are you going to tell destiny to go fuck itself, take up a weapon, and fight until you are shoved six thousand feet into the dirt?!"

  • You Are Not Alone: Said by Charlotte even after she loses to Tabane for Kira's heart.
