Main Story:
At the all-new Mihama Academy, elite students hone their extraordinary skills—sometimes on the job. "Mad Dog" Rena, a marksman; sniper Tohka; demolition expert Chris; spy Maki; and their handler Haruto make up "SORD" (Social Operations Research and Development).
Mihama Academy now entrusts live weapons to these so-called "misfit" girls, sending them on missions no one else dares to take. They plunge headlong into high-stakes, extrajudicial operations, fighting for their country, their future, and each other—with safety never guaranteed.
A thrilling, challenging visual novel where duty and danger intertwine.
In Volume 4, new recruit Megumi Kumashiro, transferred from St. Aile Academy, continues her sniper training with Rena and Maki under Tohka's watchful eye—meanwhile, Mihama Academy welcomes another new member: Taiga Sengoku. To prove she is worthy of joining Mihama Academy's elite A-rank unit, Taiga must train under Chris's guidance.
Though Chris and Taiga seem unlikely allies, they begin to see eye to eye. However, when a terrorist attack strikes, Chris—just as in the past—risks everything and rushes onto the battlefield.
"This is worse than we imagined..."
"Two people are dead! What happened? What on earth happened!?"
"Do you know what it means to bring nuclear weapons into the country...?"
"Shooting someone for the first time is terrifying... my legs are shaking."
"That fool... is she trying to ruin everything!?"
The death toll keeps rising, but SORD can only stand by and watch helplessly. What will become of Chris, Taiga... and Mihama Academy?
"Oh, right... I'm definitely dead..."
As duty and memory collide, the spotlight turns to Chris. This time, what sacrifice will she make?
