TRILLION GAME

Haru Tennoji and Manabu Taira, known as Gaku, meet again after school and decide to build a company with one impossible target, to earn one trillion dollars. Haru has confidence, charm, and the ability to talk his way into rooms where he has no right to be. Gaku is shy and poor at selling himself, but he is a gifted programmer who can build what Haru promises. After Dragon Bank rejects Gaku and tries to take Haru instead, the two refuse to become employees and start Trillion Game from nothing. Their first steps are rough. They enter a security contest, chase investors, and sell plans that are barely ready, using Haru’s nerve and Gaku’s code to survive each deadline.

The company grows through risky moves that look reckless until the result appears. Kirika Kokuryu from Dragon Bank becomes both threat and possible ally, while the old corporation keeps trying to absorb or crush them. Haru and Gaku move from app development into games, media, advertising, and live commerce, changing direction whenever a larger opening appears. Rinrin joins as their first president in name, helping turn chaos into structure. Each deal forces them to bluff, borrow credibility, and build the product after selling the dream. Haru pushes forward even when the cost is trust, while Gaku keeps asking what kind of company they are becoming. Their rise is not a straight climb. It is a sequence of negotiations, betrayals, launches, and public gambles where friendship is tested by ambition, and the dream of a trillion dollars becomes less about money than proving they can change the board before stronger players remove them.
