Iwao Asakura—also known as Gen—serves as president of Asakura Corporation, a demolition subcontractor. He recovers his drive as a world-class demolition engineer after Keiko Otsuki, an employee of major general contractor Sanyu Heavy Machinery Lease, presents him with a demolition assignment. He agrees to her offer to join the Sanyu Group and establishes the company Sanyu Blasting Co. Later, he brings on board an old acquaintance named Roku Iwashita (nicknamed "Roku the Tugger"), a wooden construction expert; Hideo Tokita (called Hide), a crane engineer who was about to end his life due to overwhelming debt; and Hikaru Nakahara, a truck driver and former TV personality. But in pursuit of becoming "Japan's number one demolition company" without being constrained by the persistent bid-rigging customs in the construction field, he leaves the Sanyu Group and re-establishes his venture as Itsumo Blowup Co. This manga ranks among the longest ever, with 100 volumes as of May 2023.
