The Bus Game is a secret corporate battle in which each company sends three of its best men to compete with teams from other companies for a disc containing corporate secrets. 

Mishiba Toki, Nakajo Nobuto, and Saito Kazuo chose to participate in the Game simply because they wanted the money they'd get if they won. Without even knowing who each other really is, they form a team called "AAA".Together, they manage to win their first Game. They had joined the game justfor kicks, but when they witness the losing team being killed, they learn that their very lives are at stake!
