As retaliation for exposing financial fraud at his employer, Tokyo Chuo Banking Corporation, Hanzawa is transferred to one of its subsidiaries, Tokyo Central Securities. There, not only is he sidelined from any major projects, he also finds that his new coworkers resent people transferred from the bank. When a huge M&A project comes in, Tokyo Central jumps at the chance to put their rivals at Tokyo Chuo in their place… And so a new battle begins for the indomitable banker Naoki Hanzawa!

After Tokyo Chuo snatches a big deal out from under the nose of Tokyo Central, Hanzawa and his assistant Moriyama vow to get revenge. But when they approach the buyer, Cyber Acrobatics, they are met with a flat-out rejection. Next they talk to the president of Spiral, the company being acquired, only to be told that a mere subsidiary like Tokyo Central cannot be trusted. Hanzawa is left wondering if there’s no way of winning again the big bank…

Hanzawa declares open war against Tokyo Chuo when he becomes an official advisor to Spiral, which Cyber Acrobatics had been seeking to acquire. Although he manages to defend Spiral against the bank’s unfair acquisition plan, the company remains in a difficult situation. Then Hanzawa comes up with a plan to turn the tables on Tokyo Chuo. But one day inspectors from the Securities and Exchange Surveillance Commission suddenly show up at Central Securities, and Hanzawa finds himself face to face with his old nemesis Kurosaki. Hanzawa suspects that Tokyo Chuo is somehow behind the surprise audit…

Thanks to Hanzawa’s plan, Spiral succeeds in pulling off a reverse takeover of Fox. However, to save face, Tokyo Chuo, at vice-president Mikasa’s urging, tries to pressure Cyber Acrobatics into accepting an additional investment of 50 billion yen so it can buy up Spiral’s stock. Hanzawa is left dumbfounded at the underhanded means that the big bank is willing to stoop to in order to get its way. At the same time, he begins to realize that Cyber Acrobatics’ earnings figures are not as transparent as they seem.
