The founders of big company Trillion Game, Haru and Gaku, are two young men who become the first Japanese people in the 21st century to be listed in the top 10 of The World's Billionaires. The story takes place from Gaku's perspective, who recalls how he came this far: his first encounter with Haru, their first establishment of Trillion Game, and people who are involved with the success of the company.

Haru Tennōji (天王寺 陽, Tennōji Haru) Voiced by: Takeo Ōtsuka (Japanese); Cody Savoie (English) Portrayed by: Ren Meguro The self-proclaimed "world's most selfish man" who aims to earn a trillion dollars by establishing Trillion Game. Haru is gifted with high communication skills, intelligence, and physical strength. He is good at negotiating, has an unmatched will to never give up, and will use any means necessary to achieve his goals. As co-founder of Trillion Game, he serves as its liaison, sales representative, and business decision maker. He was once a part of Dragon Bank Enterprises, a large corporation runs by the Kokuryū, but quits after they refuse to hire Gaku. He values Gaku and his engineering ability and would support him anytime. His speciality dish is a large-portion spicy fried rice. He is multilingual; fluent in, including but not limited to, English, Chinese, and French. It is still unknown why he is nowhere to be seen in the present timeline. Manabu Taira (平 学, Taira Manabu) / Gaku (ガク) Voiced by: Shōya Ishige (Japanese); Chase Kloza (English) Portrayed by: Hayato Sano The main narrator of the story, who established Trillion Game with Haru and serves as President of the company in the present timeline. Contrary to Haru, he is reclusive, timid, socially awkward, and weak-willed. His first encounter with Haru was when he saved Gaku from being bullied, where Haru found out about Gaku's talent. A computer otaku who, despite being self-taught, has a skill on par with professionals: he hacked into Dragon Bank's server and discovered a fault in the company's security system. He unintentionally admitted this during his job interview there, which caught Kirika's attention. His nickname "Gaku" is the result of the on'yomi reading of his first name. One of his treasured asset is a ¥200,000 (around $1,300) office chair that Haru bought for him using their starting fund. Kirika Kokuryū (黒龍 キリカ, Kokuryū Kirika) / Kirihime (桐姫) Voiced by: M.A.O (Japanese); Katelyn Barr (English) Portrayed by: Mio Imada The board director of Dragon Bank and the only daughter of its President, Kazuma Kokuryū. She is nicknamed "Kirihime" by the media for her atmosphere and personality. While brilliant and calm, but she is also arrogant and irreverent, treating everyone around her in a business-like manner. Kirika likes people who "can do their job" and has a keen eye for people, as well as a selfish nature inherited from her father. She became obsessed with Haru and Gaku after witnessing what they are capable of and has been trying, unsuccessfully, to bring them under her control. Despite this, there are multiple times when she helps Haru and Gaku, thinking it's more fun that way. Rinrin Takahashi (高橋 凜々, Takahashi Rinrin) Voiced by: Yuki Tanaka Portrayed by: Riko Fukumoto The President of Trillion Game, who was only a college student when she was hired. She is known for being too stiff, which was a part of the failure in her job hunting. However, her personality makes her sensitive to even the tiniest detail, a trait neither Haru or Gaku possesses. Before joining Trillion Game, she worked part-timer at a flower shop, which helped her gain extensive knowledge about flowers. Using this, she posed as Trillion Game's then-fake AI system "Torinrin", offering consultations about flower arrangement through the company's online flower shop "Yorinuki". As an actual AI replaced her job and she graduated from college, Rinrin officially become the company's President.
