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.

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.

Several years after The Fruit of Grisaia... 
 
What was once "Mihama Academy," a sanctuary for young girls, has now been transformed into a SORD (Special Organization for Research & Development) training school dedicated to fostering talent for national defense. Rena and Maki specialize in firearms, Tohka and Gumi excel at sniping, Chris handles explosives and data processing, and Murasaki is a skilled ninja for intelligence operations. Together, they take on cases too complex for the police or Self-Defense Forces, repeatedly facing dangerous missions. This is the story of these young girls, painted in blood and gunpowder.

While Rena and Maki recover from their injuries, the other SORD members jet off overseas for a school trip. Within moments of their arrival, though, the Mihama gang are pulled into a manhunt for a SORD deserter, assisted by student Sylvia and Velvet of St. Aile's International School. Tohka's the star of the show this time round, but she's wrestling with her own issues - old memories of her parents, and a promise to a friend that she wasn't able to keep...
