Character Arc
Naoki Hanzawa is the determined protagonist of the series, an employee of a large Japanese megabank who entered finance hoping to help honest businesses thrive. The son of a small factory owner who struggled to secure fair treatment from lenders, Hanzawa carries a personal conviction that banks should serve people rather than crush them, which puts him at odds with the political, blame-shifting culture around him.
In the first season Hanzawa is posted in Osaka and finds himself blamed for a huge loan that cannot be recovered, the result of pressure from a powerful superior. Rather than quietly accept the fate his bosses have arranged, he investigates, gathers evidence, and turns the tables on those responsible, channeling his resolve through his trademark vow of baigaeshi, or double payback. The second season extends his battles into securities and corporate restructuring, where he again confronts entrenched leadership.
Across both seasons Hanzawa is defined by integrity, stubborn courage, and loyalty to colleagues and clients who have been wronged. His confrontations are staged with theatrical intensity, and his insistence on accountability over self-preservation made him an aspirational figure for many viewers.
