Gyro Zeppeli's Mission (ジャイロ・ツェペリの宿命 Jairo Tseperi no Shukumei) is the third story arc in Steel Ball Run.
Gyro objected at Marco's execution since he was unrelated to the crime, but he didn't have any way to stop it. One of the counselors he knew proposed him to participate to the Steel Ball Run race, as winning could bring Naples enough glory for the King to proclaim a general amnesty, otherwise the prize money was enough to pay for Marco's appeal. Gyro accepted.
Oyecomova arrives at a relay village where the racers are supposed to register themselves. He realizes that Gyro, Johnny and Mountain Tim have arrived before him. Mountain Tim confronts Oyecomova but is incapacitated by his Stand Boku no Rhythm wo Kiitekure's explosive power. Oyecomova reveals then that he is after Gyro's head.
