Trillion Game Meet Haru Tennouji, a charismatic communicator beloved by all, regardless of age or gender. He may come across as easygoing, but beneath that façade lies an unwavering ambition for success.

Their audacious objective: to amass a staggering 1 trillion dollars. Now, let's introduce Manabu, a brilliant engineer armed with remarkable IT acumen. Personality-wise, he's the antithesis of Haru—introverted, and a tad awkward in social interactions.
