Hanzawa Naoki Season 2

Unconventional banker Hanzawa Naoki has been successful in exposing numerous irregularities at his bank,
the Tokyo Chuo Banking Corporation.
As a result, he is seconded to Tokyo Central Securities (TCS) to head their Corporate Development Department. Soon after, the TCS is involved in a hostile takeover by a large IT company. With the share purchase price expected to surpass 100 billion yen, it is a deal worth an unprecedented amount to TCS. Unbeknownst to Hanzawa, the bid will incite a competition war with a new bank. Will he be able to overcome the problems plaguing the TCS and inflict twice the pain on those making unreasonable demands?
