B'T X Neo

After a battle that nearly ends their journey, Teppei and his mechanical partner B'T X receive Hokuto's help and return with renewed strength. Teppei remains determined to reach his brother Kotaro, a captive of the Machine Empire.

The route deeper into the empire grows more dangerous as the threat posed by Raphael expands beyond the brothers' plight. Shifting loyalties among the warriors they encounter turn a personal rescue into a struggle with far wider stakes.
