The film opens on Genm Corp, which falls under attack by a trio of gun wielding terrorists in white suits, with the big muscular one of the trio shooting his gun in the air to scare away the company employees. They use their combat skills and firepower to swiftly deal with security by killing the guards. A fourth member appears to join with the trio once the commotion dies down a bit, a mysterious figure who is phasing in and out of existence and wearing a Pac-Man mask. An alarm goes off and the surviving security warns Kuroto Dan on the phone in his office that there are hostile intruders coming toward his floor. Kuroto tries to pack up the Proto Rider Gashats and his Gashacon Bugvisor and flee, only to be held at gun point by the three armed terrorists. They seem to know who Kuroto is and the female terrorist says it has been six years since they last saw each other.
