Taira “Gaku” Manabu has always dreamed of working for Dragon Bank, Japan’s biggest tech company. While he’s super smart, he freezes up on the interview and as a result, ends up having to pick up part-time jobs to make a living. Tennoji Haru is not a computer-whiz, but he’s super charismatic and outgoing, and he easily convinces Dragon Bank executives to hire him. On the first day of the job, at orientation, Gaku runs into Haru while outside the Dragon Bank building, cleaning its windows… because Haru apparently had quit his job at Dragon Bank! Haru vows to make a company with Gaku that will be worth a trillion dollars.
