[Machine Translation] Two years ago, Tsuyoshi took the signal chaser with him. With Chase's death on his mind, Tsuyoshi returns to Japan in search of a trigger for a new drive system. Suddenly, however, the city is hit by a massive power outage at night. It's just like that! The dark Holy Night incident flashed through Tsuyoshi's mind. Reumud? No, all the Reumuds must have been eradicated. Is this just a coincidence or...? Just as Tsuyoshi had feared, a series of phenomena very similar to the past Reumud incidents occurred. Will Tsuyoshi be able to transform into Mach again?
