In 2014, a high school student named Akira Natsume endures a phobia of electrical devices while also being very good at diagnosing them. He leads an average, unfulfilling life, and resolves to change himself for the better and get a girlfriend after being motivated by his older brother. Soon after, he suddenly dies in an accident. 16 years later, a young policewoman named Minami Uenozono and her android partner Alma retrieve and activate a highly advanced AI superweapon known as an ＂Ex-Arm＂ and put it into full control of their ship as a last resort. The AI turns out to be Akira's brain, now in a digital form. The series revolves around the police force's attempts to suppress and defeat adversaries using Ex-Arms for their own purposes.
