Kimimaro Yoga, an economics student raised by his grandmother after his father disappeared and his mother died, wants nothing more than a stable life. A stranger named Masakaki lures him into the Financial District, an alternate dimension where Entrés stake their own futures in combat and win real money that ripples back into the outside world. Paired with an Asset named Mashu, Kimimaro draws the attention of Soichiro Mikuni, the district's most powerful Entré and founder of the Starling Guild, whose way of shielding Japan's economy costs more than Kimimaro can yet see.
