Self-proclaimed "world's greediest man" Haru and timid computer whiz Gaku set out to make a trillion dollars. They start the company Trillion Game to accomplish this task and hope to iron out the details as they go. With charm, technical skills, and no business plan, can these unlikely friends reach their lofty goal?

In order to sell their (not so) AI-powered flower-vending business, Haru and Gaku must first conquer the nightlife neighborhood of Kabukicho, where there is a huge market for fancy flower arrangements. After they pull off their scheme and make the sale, the next frontier for their business is...mobile gaming?!
