Main Story:
At the new Mihama Academy, elite students hone their unusual skills—sometimes on the job. Rena “The Rabid Dog,” a gunslinger; Tohka, a sniper; Chris, a demolitions expert; Murasaki, a spy; and their handler Haruto form SORD: Social Ops, Research & Development.

Mihama now entrusts these so-called misfit girls with live weapons, sending them on missions no one else dares to take. Safety is never guaranteed, as they plunge headfirst into high-risk, extrajudicial operations—fighting for their country, their futures, and each other.

A gritty, action-packed visual novel where duty and danger collide.

In Vol. 4, Kumashiro Megumi, the newest transfer from St. Aile’s, continues her sniper training with Rena and Maki under Tohka’s watchful eye—while Mihama Academy welcomes yet another recruit: Sengoku Taiga. To prove herself worthy of Class A, Mihama's elite combat unit, Taiga must train under Chris.

Though unlikely allies, Chris and Taiga start to see eye to eye. But when a terror attack strikes, Chris rushes into the fray, risking everything just like in her past.


“This is even worse than we could’ve imagined...”

“Two of the guys are dead! What happened? What the hell happened!?”

“Y’know what it means to bring nukes into the country...?”

“It’s scary, shooting someone for the first time... My legs are shaking.”

“That fool... Is she trying to ruin everything!?”

The death toll keeps on rising, but SORD are stuck watching helplessly from the sidelines. What destiny awaits Chris, Taiga... and Mihama Academy?

“Oh, right... I must have died...”

Duty collides with memory, and the spotlight turns to Chris. What sacrifices will she make this time?
