10 Years Grand Prix
In the year 2018, ten years following the battle against Gaiark, Bus-on and the other Engines were barred from entering Human World by the Isolation Barrier erected by Noizoon. Thanks to a breach in the dimensions caused by Kitaneidas, the Go-Ongers' partner Engines were able to enter the Human World and join the fight against the Eleki Clan Zontark, saving their human partners from the three Zontark members as Bus-on reunited with Renn. Ultimately, the seven Engines combined to form Engine-O G7, which performed the 10 Years Grand Prix to destroy Noizoon.
Buson narrates a total of eight episodes.
