In Steam City's coal mine, an excavation was stopped due to a cave in. However, one of the miners believes that the cave in was caused by a giant mole creature. Narutaki joins the local police on the site, and another mineshaft comes across a new cavern that has been recently dug. Narutaki takes Goriki with him, and while in the cavern, they come across Dr. Guilty's latest creation: Shadowbolt Mark II. After a quick fight, Shadowbolt II escapes, but our heroes are caught up in a cave-in. Making matters worse, Dr. Guilty brings his creation downtown and begins tearing up the city. Will our heroes escape the cave-in and will they be able to fight?
