About Trillion Game
Trillion Game is a Japanese live-action business drama produced by TBS and adapted from the manga written by Riichiro Inagaki and illustrated by Ryoichi Ikegami. The series follows Haru Tennoji, a charismatic and audacious young man who declares that he wants everything in the world, and his brilliant but introverted engineer best friend Manabu Taira, nicknamed Gaku. Armed with nothing but bluster, ambition and Haru's preternatural gift for charming anyone he meets, the pair set out to build a business empire from absolute zero and scheme their way toward a fortune of one trillion dollars.
Where Haru talks his way into rooms he has no right to enter, Gaku quietly turns those impossible promises into working technology, making the duo a complementary engine of hustle and genius. Each arc pits their tiny upstart venture against entrenched corporations, ruthless investors and rival founders, and much of the fun comes from watching Haru bluff, negotiate and improvise his way out of situations that should sink them. The tone is slick and playful, leaning into the wish-fulfillment energy of a business underdog story rather than gritty realism.
Leading the cast is Meguro Ren of the idol group Snow Man as Haru, with Sano Hayato as the gifted, soft-spoken Gaku and Imada Mio as Kirika Kokuryu, a sharp banking heiress who becomes entangled in their rise. The drama aired on TBS in 2023 across ten episodes and was followed by a continuation film in 2025, extending the story of Haru and Gaku's relentless climb. AI-authored and flagged for fact-check.
