which was classified as "Alpha-worm". Conventional medicine had no effects on the patients and the worms deformed the victims, but the infection increased the strength and resilience of the people infected. The infected eventually broke free and attacked the researchers and, due to a fear of an outbreak, the military assaulted the facility and destroyed all traces of the infected. To prevent panic, governments of the world kept the Alpha-worms secret. The G.U.I.D.E (Global United Infestation Detection and Elimination) force was formed by Agent Michael Wilson, recruiting elite operatives from around the world. Eventually, after a massive outbreak of Alpha-worm infestation takes over the city of Tokyo, an elite ninja team including the young Ken Ogawa, and led by his father Kanbe, is sent to deal with the situation.
