Want to Go Home but Can't

The Zyumans cannot return to Zyuland until they find the missing sixth Champion's Proof. Amu thinks she has found it and takes Yamato along with her, but she seems more interested in experiencing human culture. Their plans are waylaid when the Dethgalien Player Bowguns attacks various cars and trucks, so the Zyuohgers face off, but find that his attacks are too fast to be seen, until Yamato seems to gain a new power.
