After the socially awkward technology specialist Manabu "Gaku" Taira is rescued from thugs by the outgoing Haru Tennouji, the two men discover they get along well. Years later, Gaku, who is struggling to find employment due to his timidity, is persuaded by Haru to apply for a position alongside him at Dragon Bank, one of Japan's largest IT companies. During their interviews, the company's board director, Kirika Kokuryuu, takes an interest in Haru and Gaku's contrasting personalities. However, Gaku is not hired by the company, prompting Haru to quit his job on his first day in protest. Nevertheless, they decide to embark on an ambitious plan to make a trillion dollars. To bring their scheme to fruition, Haru and Gaku begin seeking potential investors, but everyone rejects their extravagant idea. Despite this, the two soon receive an offer from Kirika—and with her investment, they might just be able to reach their goal.
