Kamikaze is unable to drive as he would like due to the shock, but the doctor still orders him to get on the machine. Ahab is not going to miss this opportunity and requests to participate in the race on the Great Snowy Mountain.

To put an end to the fierce battle, Ahab takes off his armor and reveals his true identity. He then challenges the Saionji Racing Team on the condition that the loser retires from the racing world.
