DJ Boy (Japan, set 1)

A young man named Donald J. Boy (DJ Boy) is a roller fighter taking part of an ultimate fight-race known as "Rollergame", taking place in Cigaretch City, located on the outskirts of New York City. Many people were excited to see DJ Boy, but a roller fighter gang known as the Dark Knights want him out of the competition. Their leader, Heavy-Met Tony, calls his gang to kidnap his girlfriend Maria, who also comes into town and defeat DJ Boy. DJ Boy must rescue Maria, defeat the Dark Knights, and win the Rollergame competition in one adventure. The arcade plot tells a different story. Two rollerskaters named Bob & Tom (the two playable characters) were breakdancing to the beat of their boombox, until it got stolen from rollerskater thieves (possibly the Dark Knights), in which they must find and defeat them in order to retrieve what is rightfully theirs.
