The Final Trial!

Synopsis

The Devil Bats truck gets stuck in a pothole; with one final push together as a team, Deimon overcomes the last obstacle. Arriving in Las Vegas, on the pirate boat outside Treasure Island, Doburoku confronts Sena to see if the ghost move is complete. Sena passes through Doburoku with the new Devil Bat ghost move, and Doburoku realizes Sena's unlimited potential. At the hotel, everyone rests in preparation for the journey home. The next day, Hiruma sells Doburoku's truck and tells him to go to the casino and bet his all on roulette 21#'s on red 21. The money pays off Doburoku's debt and he returns to Japan with the team.
