Long story short this is a combination of my creative ADHD and reading a bunch of light novels online.

And yes I am still working on my other stories.

So, you know those stories about where you have a clueless, but kind to a fault teenage protagonist, who due to some unbelievable circumstances ends up being sole hope of the world, and he usually has some weird op power or specialized weapon/machine he can use to slay his foes?

Also he is typically surrounded by beauties of several types. Typically, one of them is extremely shy, and violent childhood friend commonly referred to as a tsundere. Along with several other colorful characters all after his affection for one reason or another?

Well keep that at the back of your mind while explain current world to you.

Humanity is at war with what are basically aliens. Around ten years ago an event that is known as the Incursion happened. Rifts opened from another world and out poured hostile invaders who started attacking people indiscriminately.

They had advanced technology that gave them the advantage in most battles and entire cities were destroyed within weeks.

But humanity if nothing else is stubborn and not exactly known for pacifism, we have ten thousand years of recorded history and never once has there been a lasting peace. Which in this case is not a bad thing.

Still we were at disadvantage and lost a lot of people…at least in the early days. Humanity was able to reverse engineer technology from the invaders. And that put us on more or less equal footing.

And there is also that…

So, remember when I said special machine?

Yeah, we got a super advanced exo-skeleton with aerial performance that out matches any top of the line aircraft currently fielded by the international military. Even the ones with the reverse engineered invader tech.

Basic capabilities, it can fly, can store an armory worth of weapons in what is called a quantum storage unit, which by using the same means can turn the suit itself into the ultimate concealable weapon. It also has advanced sensors that I'm told gives the pilot a 360-degree view.

That doesn't even begin to cover the way it flies. Simply, it uses a system to defy the laws of gravity.

So, it's basically some unbelievable machine that I'm convince runs on magic more so than science. It was also made by a crazy woman with a fetish for Alice in Wonderland.

I'm not joking.

Her name is Tabane Shinonono, My older sister was 'friends' with her. They have an odd relationship that's not friendly but they aren't enemies. Also, the hostility comes from my sister, as far as Tabane is concerned they are still BFF's.

My sister never explained why she is on bad terms with her, but she has good reasons for what she does. And I trust her.

That and she also happens to be the commander of the International Infinite Stratos corp.

By the way that machine I mentioned is called the Infinite Stratos. I forgot to mention that before, sorry about that. Most people refer to it as an I.S. for short.

Fun fact about the I.S. it can only be piloted by women save for one exception.

Remember my monologue about the generic harem protagonist earlier?

Well despite me being the narrator of this fun little story, it's not me.

Our current harem king is Ryugo Shinonono. Son of Tabane Shinonono, and current star of hope for the human race.

Tabane genetically constructed him using her DNA to be ideal human. Strong, intelligent, admittingly (begrudgingly) handsome. He is charismatic and has about ninety percent of the I.S. corp. head over heels for him. half of the last ten percent have 'other tastes'. The last five percent just don't care or are already in a relationship.

Personally I think he is a giant douche.

My name is Corporal Ichika Orimura, 2nd battalion, 1st brigade, 18th division of the International Armed Forces Far Eastern Branch.

Age Fifteen, conscripted veteran of two years of constant fighting.

So, this is not my first iteration of an interdimensional alien invasion for an I.S. fanfic. I tried doing one before my computer died a few months ago and tried doing it again until recently.

That's when I read a certain light novel called the Spear User Who Couldn't Become a Hero.

Which has…

an alien invasion

A side character that is set up with a harem for plot relevant reasons (it's hinted that they aren't actually in love with him). While he isn't exactly a douche he is a jackass that is OP.

The main character while not weak and is incredibly skilled, does have OP powers.

It's pretty interesting because some chapters are propaganda way in the future after humanity won praising the Jackass as savior of mankind aka a messiah. And our MC as a villain whenever he's mentioned.

Despite this he's nice guy that is handy with a spear. There's just a conspiracy working against him down playing any achievements he gets.

When I say nice, I mean he's not foul mouthed and will take most insults without complaint. But he will drop your ass if you threaten his friends or those he's been charged with protecting.

Makes you want to root for him doesn't it.

This new story is also my wish for there to be an anime like this instead of the mecha pilots being the stars I want those red shirts dying in the back round to have their time in the spot light.

You know skilled but not overtly so, surviving by the skin of their teeth while bringing in amazing victories.
