Composer Toshihiko Sahashi’s booming, dramatic horn-and-string main theme elevates the stakes. It frames Hanzawa's quest not as a corporate dispute, but as an epic crusade.
This culture clash is personified by Hanzawa’s immediate superior, Branch Manager Asano (Kanji Ishimaru). Asano is ambitious, unscrupulous, and firmly believes in the toxic corporate rule: "the superiors take the credit for the subordinates’ successes, and the subordinates take the blame for the superiors’ failures". When a suspicious company, Nishi Osaka Steel, applies for a massive, unsecured loan, Hanzawa’s due diligence raises every red flag. However, Asano, seeing a path to a branch excellence award, forces Hanzawa’s hand, overriding his judgment and uttering the fatalistic words: "I will take responsibility".
