Haru Tennouji is a charismatic communicator who is beloved by everyone, regardless of age or gender. He may seem easygoing, but beneath that façade lies an unwavering ambition for success. When offered a prestigious position at the nation's largest IT company, "Dragon Bank," he does the unexpected—turning it down to embark on an entrepreneurial journey with his friend, Manabu Taira. Their audacious objective is to amass a staggering 1 trillion dollars. Manabu is a brilliant engineer with remarkable IT acumen. Personality-wise, he is the antithesis of Haru—introverted and a bit awkward in social interactions. After being rejected by "Dragon Bank" due to his communication challenges, he joins forces with Haru, sharing in the colossal ambition of earning that elusive 1 trillion dollars.
