had anything to do with Yoyo, they go and graffiti their turf: the Skyscraper District & Pharaoh Park, Hikage Street, Kibogaoka Hill and defeat the Immortals in Highway Zero. In doing so they reveal they had supposedly kidnapped Yoyo; however, when he is freed, he turns on the GGs and enslaves them under the Noise Tanks' control. The Noise Tanks then have the gangs under their control battle in the game "Death Ball". Those who lose are brainwashed and controlled by the Noise Tanks for life. The GGs succeed in all three games, one against the Doom Riders, one against the Immortals and one against the Love Shockers, but then the Rokkaku Police suddenly appear and crackdown on the whole final game. When the GGs win this battle again, the Noise Tanks become furious, releasing hundreds of Noise Tank androids to terrorize the street. When the GGs clear out all of the androids, they discover a wounded Poison Jam, who reveals that Yoyo had beaten him and ran off to the nearby amusement park called Sky Dinosaurian Square. There, it is revealed that 'Yoyo' was a Noise Tank in disguise, and the real Yoyo had been missing the whole time. After the GGs defeat them, a mysterious man destroys the Noise Tanks and runs off. They soon discover the Noise Tanks were built by the Rokkaku Group to take over the gangs of Tokyo. After the Noise Tanks are destroyed, two new threats appear: a Yakuza-style gang called the Golden Rhinos who are bent on eliminating all graffiti in the city, along with executing all Rudies; and an insane demon-like creature who sprays odd graffiti and looks strangely like one of the GGs, Beat. Amid all this heat, the GGs are approached by Clutch, a Rudie who knows where Yoyo is; the player needs to find a certain number of Graffiti Souls for the info. When the GGs give him his payment, he runs off without telling any information. They chase after him in either Chuo Street, Kibogaoka Hill or the Skyscraper district and Pharaoh Park and interrogate him, where he apologizes and says he was "just having a little fun", then reveals Yoyo was taken to the Fortified Residential Zone inside of the Sewage Facility. When they arrive, they discovered the place was rigged with bombs by the Golden Rhinos. They disable them all thinking they finally saved Yoyo
