Three complete strangers—Mishiba Toki, Nakajyo Nobuto, and Saitoh Kazuo—are recruited by a corporation to participate in the Bus Game, an illegal underground dog-fight conducted in absolute secrecy. Assigned the team code "Team AAA" (Triple Anonymous), these three individuals, who come from vastly different living situations and have completely distinct personalities, must collaborate effectively. However, they are not allowed to dissolve their mutual distrust or intrude into each other's private lives. Their sole commonality is that each of them urgently requires a large sum of money for personal reasons. To obtain that money, they must compete in the game, even though their own lives hang in the balance.
