Following the Heath Oslo incident, the existence of the US-Japanese anti-terror organization CIRS has become a matter of public knowledge. CIRS has been rebuilt from the ground up, and its most covert functions spun off to a new agency: SORD (Social Ops, Research & Development).

The goal of SORD is to train a new generation of operatives to defend the country against future threats. To that end, the organization has established a series of schools up and down the country. Mihama Academy, more-or-less left to rot after its abrupt closure, has been given new purpose as one such 'specialist training school'.

This new incarnation of Mihama Academy is home to a diverse group of students, who every day work to polish their unusual skills - sometimes on the job. Mihama now entrusts the misfit girls who attend it with guns and live ammunition. Paying their own safety no heed, these students are again and again plunged into dangerous extrajudicial missions - all for the good of the realm.

"We've been granted a place in the world.
That alone isn't enough - there wouldn't be any meaning in living, if that was all we had...
It's not enough just to get by on the backs of others.
I live by my own strength, and I fight to survive.
Because only the survivors among us belong with the living..."

No matter how much life grinds them down, what future awaits these girls, who've themselves chosen the path of the gun?

Voiced byIzawa Mikako


The unfortunate new homeroom teacher at this unusual school, who really has no idea what she's gotten herself into.

An extremely earnest young woman, she can end up letting people walk all over her in her efforts to accommodate them. She's perhaps best described as 'unassuming' - or, more to the point, 'cowardly'. She wouldn't look out of place as a nameless NPC in some generic role-playing game. She doesn't have much luck at work; she's the type to end up causing a huge calamity, and then get caught out straight away by her superior.

According to Arisaka herself, she was equally unlucky as a kid - she's always drawn the short straw. Sometimes it can genuinely seem like she's cursed.

Other than that, though, her life is pretty ordinary. Mundane, even. That can seem like a breath of fresh air somewhere like Mihama Academy. Like everyone else, she appears simply to have drifted into the school.

"It might be too late at this point, but do you really think I'll be alright?"

A former CIRS agent who now serves as a tactical instructor at Mihama Academy, and as a handler to the school's students. Though he looks young, he has a great deal of experience on the field, and he still has lots of friends on CIRS' current roster.

Haruto radiates warmth and gentility, but this has left him an object of teasing at Mihama - the girls under his charge tend to treat him like he's just another kid. He can also be pretty tight-lipped about his past. Some of his memories are in fact rather vague, and there remain lots of gaps in his work history.

Gunplay really isn't Haruto's strong suit. He doesn't often succeed in striking his target (though some people believe this apparent ineptitude to be a deliberate ploy on his part).

He has little interest in food, and will usually make do with just a salad.

Haruto will often issue strategic commands on the battlefield, but he rarely finds himself standing in the trenches. He uses a sword, but not one made in the Japanese fashion; it would certainly be a bit of a stretch to call it a katana.

"Haha, my classmates often tell me I'm a total asshole."

A gunwoman who's charged with shooting on Haruto's behalf, due to his personal distaste for firearms. Rena's a lively girl, amiable and warm in her dealings with just about everybody. She's tall and well-proportioned, her limbs smooth and powerful. She makes sure to stay healthy and active.

Rena has a strong sense of responsibility, and tends to be quite cautious; she's always scanning the environment for threats. Her loyalty to Haruto, her 'Master', and the docility she demonstrates around him, are most notable.

However skilled Rena is physically, she struggles quite a bit in the classroom. When told off, she quickly grows timid; she has a good appetite for learning nonetheless, and responds well to praise.

She favors an M1911-style pistol, and lets loose about two hundred rounds every day.

Rena also has a tendency towards obsession. Once she develops an interest in a handgun, she can't make do with any other weapon until the heft of that particular gun is ingrained in her senses. Though law enforcement agencies having summarily dismissed the superiority of .45 ammo, Rena obstinately persists in using it, even going so far as to get lightweight bullets specially manufactured by the school gunsmith.

She has a motorcycle license, and when she's feeling particularly ravenous, she'll often sneak out in the middle of the night for ramen.

"I haven't had a really filling meal recently - like sushi, or something nice and meaty..."

A self-proclaimed 'Russian ninja', Murasaki's actual heritage is shrouded in mystery.
She makes all sorts of claims about her 'ninja skillz', including her certification as a 'master ninja'.

Her real forte is disguise, and she takes on a lot of missions involving stealth and infiltration; her calling-card is the .22 subsonic ammo she always uses. Alongside easily concealable weapons like small-bore automatic pistols and her kunai, or Japanese dagger, Murasaki's fond of katana swords and rifles.

Her personality can be difficult to pin down; she rarely displays her true feelings in front of others, and obviously has fun saying weird things to confound other people. Even during the summer, she wears a long scarf around her neck to signal her ninja identity. At first glance, it looks like the kind of scarf a normal female student might wear, but it's actually woven from a mix of aramid fiber and synthetic protein, making it both bullet-proof and fire resistant.

Murasaki's been friends with Haruto since she was a young child, and loves him like an older brother. Or could her adoration for him be something more?

She ranks third in close-quarters combat, her ferocious speed losing out to Haruto's skill and Rena's raw strength.

"... Yeah. I just like ninjas, that's all. I an be anywhere and everywhere."

An explosives and computer specialist, born in Shanghai to British parents. Of the 148 students at Mihama Academy, Chris is ranked eighth in terms of test scores, and she's ended up in charge of helping the rest of the class with their studies. She comports herself well around other people, and ordinarily seems quite meek, but she's said to become genuinely scary when she's angry.

Just like Haruto, Chris isn't too fond of guns, and generally refuses to carry one. In fact, her standard-issue handgun is a defective model that ought to have been returned to the manufacturer, and that doesn't appear to bother her in the least.

She used to wear her beautiful blonde hair down past her shoulders. When she was in elementary school, though, she accidentally set off a bomb in the school toilets, and singed her hair; ever since then, she's kept it short.

A helpful girl who's proficient in every kind of household chore, Chris is something of a den mother to the other students: she prepares meals in the student dorm, cleans her friends' bedrooms, and does their laundry. She also has rather poor eyesight, wearing contact lenses almost all the time. Only in the brief moment between her waking up and washing her face will you find her in glasses.

"I see. In that case, don't hesitate to call for me if you do happen to step on a landmine."

A sniper. Her mother is German, her father American. Growing up, Tohka learned self-defense techniques and riflery from her father, a former soldier, and his comrades; she was the youngest ever winner of a shooting competition in her hometown. In the wake of her mother's death, she spent two years attached to a PMC (private military contractor) alongside her father.

She can be extraordinarily belligerent, and sometimes breaks into outbursts of violence. She is, in short, a classic tsundere. Though infinitely curious about the world, she has a pragmatic side, too: she won't tolerate any nonsense. She possesses a measure of shrewdness and inner strength that belies her cute, childish exterior.

Whenever she was left home alone as a child, Tohka would shove a shotgun in the face of any cold-caller who came knocking; she's since become known for her shyness around strangers. She tends to take an instant dislike to anyone she meets. She's clearly desperate to be regarded as a friend by others, though, however little effort she exerts in this regard herself.

She's basically pretty bad at making friends. She also has a bit of a complex about her small stature, and it's to compensate for this that she tries to act all grown-up.

"Really? Then listen up, all of you! Calling me 'cute' IS badmouthing me!!"

Nogami has worked as Sengoku Ichiru's assistant ever since her time in CIRS’ Special Medical Division, and she continues to uphold that role at Mihama Academy.

While brilliant, she also possesses several personal faults that get in the way of her day-to-day life. Case in point: the fact that her room is always such a total mess. Haruto thinks of her as a sort of surrogate older sister, turning to her first whenever he has issues that he's reluctant to discuss with Principal Sengoku.

"Nogami is fine."

Thanks to her background, she has a lot of pull with the upper echelons at CIRS. It's rumored that in the course of her work for the organization, she's come to learn the weaknesses of many of her fellow agents. This may have been a key factor in her "retirement" when the organization was restructured.

A report at this time detailing the gap between the American and Japanese intelligence services in terms of both efficacy and intelligence-gathering capabilities inspired Sengoku to create SORD (Social Ops, Research & Development); she then used her dismissal as an opportunity to establish herself, and SORD, as a leading force in tactical development.

Every now and then you can find her zoned out and thrashing away at her air guitar, while a thumping beat blasts through her headphones.
