The Invaders took over a small mountainous town, slowly killing off the population and possessing their bodies. Yuki investigated the area when some of her friends went missing. Before long the Invaders made themselves known to her and four of them combined together to form the monster Shadow Mons. The four horned monster quickly set the town aflame with his fire. Kyotaro saw what was happening and turned into Mirrorman to fight. The hero kept away from Shadow Mons's flames, Jumbo Phoenix soon spotted the two giants fighting each other and used special anti-fire cartridges to dowse the embers.
