Genzō Tamura is a 19-year-old third-generation construction worker from Beranme's working-class neighborhood, upholding his family's carpentry tradition on local building sites. His trusty hammer serves as both his essential trade tool and a means to defend his community. When the Kuromoku Group's destructive redevelopment plans threaten Beranme, employing aggressive agents Chainsaw Mika and Dynamite Dan for demolition, Genzō confronts them directly. He wields his hammer against their destructive methods to resist the forced redevelopment. His actions are driven by a commitment to preserve Beranme's existing community and way of life from corporate encroachment, operating within a slapstick comedic framework during these conflicts.
