Young kendo prodigy Ranmaru Samejima captures the attention of Kei Enjoji, the illegitimate son of a yakuza boss. Kei, determined to form a bond with Ranmaru, cultivates a friendship built on trust and sacrifice, which soon turns into love. After saving Kei from a yakuza hit-and-run attack, Ranmaru is forced to give up kendo forever, and the two are left with only their faith in one another. Vowing to support each other far from the world of the yakuza, the two begin living together as a couple. However, when a mysterious figure from the pair's past returns in pursuit of Ranmaru, they are thrust back into the world they fought so hard to leave—and their love may not be strong enough to survive it.

After socially awkward technology specialist Manabu "Gaku" Taira is saved from thugs by the outgoing Haru Tennouji, the two men find that they get along with each other well. Years later, Gaku, who is having a tough time getting a job due to his timidness, is convinced 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 does not get hired by the company, leading Haru to quit the job on his first day in protest. Nevertheless, they decide to embark on an ambitious plan of making a trillion dollars. In order for their scheme to come to fruition, Haru and Gaku start looking for potential investors, but everyone rejects their extravagant idea. In spite of that, the two soon find themselves getting an offer from Kirika—and with her investment, they might just be able to reach their goal.
