There’s a gunslinger called Rena (nickname: “The Rabid Dog”), a sniper named Tohka, a demolitions expert called Chris, a spy named Murasaki, and finally, Haruto, their handler. Together they make up an agency called SORD (Social Ops, Research & Development). The specialist training school now entrusts the misfit girls who attend it with guns and live ammunition in the name of national defense.

Story:

5:30 AM – U__ Harbor, K__ Prefecture.
A VIP arriving from abroad mysteriously disappears in transit. The SORD team at Mihama Academy (Rena, Tohka, Chris, and Murasaki) are presented with a new mission: finding and recovering him.
Whenever they appear to be closing in on this missing “package”, though, it somehow slips through their fingers.

Accompanying them on their mission are two fellow SORD members from the Kyousen Sakuragaoka campus – twin sisters, who both help and hinder the crew.
There have also been rumors floating around of a daredevil biker named “Soul Speed”, who tears up the streets at night. What role might she play in this escapade?

Before long, the team’s thrilling chase descends into a deathmatch, pushing the combatants to their limits and beyond. Rena and Haruto, meanwhile, are taken on a journey deep into the past, to their first ever encounter.
