Hanzawa Naoki works as a loan manager for a bank in Tokyo. It follows his journey as he climbs the career ladder while exposing the many corrupt wrongdoings that his superiors have been involved in.

Kosaka Kei works as a programmer for IT company Spiral. The Tokyo Central Stock Exchange is about to overhaul their financial security system for the first time since their company was founded. The stock exchange will take bids for the work. Spiral is one of the companies taking part in the competition for the winning contract. Hamamura Hitomi is a new employee at Tokyo Central Stock Exchange. She receives training in the information system department. She meets Kosaka Kei and they take interest in each other.

Hanzawa Naoki has been ordered by his president Nakanowatari Ken to transfer to the subsidiary Tokyo Central Securities, despite his success in exposing a number of misdeeds led by the managing director Owada Akira. He is given the position as head of the corporate development department. One day, Tokyo Central Securities gets a big deal. A large IT company called Cyber Acrobatics offers to acquire Sena Yosuke’s Spiral, one of the leading companies in the industry. It is a deal on an unprecedented scale for Tokyo Central Securities, with the share purchase expected to amount to over 150 billion yen. He has yet to realize that this will trigger a new battle with the bank.
