Tatsuhiko, an unemployed young man, gets into a fight with a gang and is rescued by Mako, a scout who recruits girls to work for the Burst scouting agency run by Yamashiro in Kabukichō, Tokyo, a red-light district in Shinjuku, Tokyo. Tatsuhiko learns the trade and becomes a scout as well, with Yosuke as his direct superior. Yamashiro, the boss of the Burst scouting agency, is pressured by a need to pay extravagant protection payments to Chairman Shuzen Amano of the Monbukai family, who demands a bigger cut due to a better offer from the rival Harlem scouting agency.
