Sasaki (佐々木, Sasaki) is a bus driver whose bus is heading for Spaceland when it is hijacked by Kiichiro Osoreda.
Sasaki has a short crop of brown hair and small brown eyes. He wears a blue bus driver's uniform and hat.
Sasaki is forced to call the office of Spaceland at gunpoint to announce the hijacking of the bus. The phone is taken from him by Osoreda, who makes his demands while holding the bus driver and seven passengers hostage. The moment Osoreda sees Ryuk, he tells Sasaki to stop the bus. He flees and is immediately hit by a car, as was written by Light Yagami in the Death Note.
He later helps Naomi Misora during her private investigation by telling her how the busjacking occurred. She shows him a picture of her with her fiancé, and Sasaki says that he remembers him, but he does not remember any of the other passengers.
