Ep. 31: Shobu and Rekuta chase a mysterious Fua Duelist onto a speeding train for a high-stakes duel.
Shobu and Rekuta notice a stranger in photos from the Duel Festival and set a trap to catch him. After the stranger confirms he is a Fua Duelist, he escapes, leading the pair to a station where staff member Zerobal Holmes directs them to an underground train. Shobu and Rekuta board, only to discover the passengers are fakes and the staff member is actually the Fua Duelist Chappi. Chappi challenges Shobu to a Non Stop Train Duel, using the train's increasing speed to pressure his opponent. Shobu wins the duel, but Chappi escapes and knocks himself out, leaving Shobu and Rekuta to stop the runaway train. Their attempt to halt the engine in the engine room instead causes the train to accelerate further, leaving them trapped on the speeding vehicle.
