|— The Speedway Five-Billion Announcer, "The Speedway Five-Billion"|
The announcer shows it as the prize of the Speedway Five-Billion and questions the racers on what it would be like to win the Key-Tana.
The yellow Key-Tana was briefly shown when the Speedway Five-Billion was being advertised.
Jay used the Key-tana to unlock the firewall, leading him to Unagami.
