The anime's main cast includes:
- Takeo Ōtsuka as Haru Tennōji
- Shōya Ishige as Manabu “Gaku” Taira
Synopsis
The story then focuses on Haru, relaxed, and Gaku, serious, two men who plan to earn a trillion dollars so they can buy anything they want in the world. Haru is an eloquent, persuasive and confident speaker, which allows him to be in anyone's good graces. Gaku is a skilled, albeit clumsy, programmer. The two were high school classmates and meet again when Gaku's application to a banking company is rejected.
Finally, Inagaki (Eyeshield 21, Dr. Stone) and Ikegami (Crying Freeman) then launched the manga in Shogakukan's Big Comic Superior magazine in December 2020. Shogakukan published the manga's seventh volume on July 12. Therefore, the manga currently has more than 1.5 million copies in circulation.
