Erika Toda and Shota Matsuda, the golden duo, are back again, ready for another intense battle. The story takes place two years later, with Naoki and the genius fraudster Akizuki once again standing before the ultimate fraud game.
The background of the story is set two years after the third round. Naoki received an invitation letter and was persuaded by the sweet talk of Kotaro Tanimura, an office staff member, to participate in the fourth round. Almost simultaneously, another office employee, Eri, approached Shuichi Akizuki, who ultimately decided to join as well.
At the venue, after two years, Naoki and Akizuki meet again. Before them are not only past adversaries like Fukuoka and others but also new members. An even more intense competition is about to begin.
