4

Ababa sends Wen and Li to take control of Cobalt Blade after Battle Crow's failed attempt. Yamato, Grey, and Bull run into Wen and Li on Delta Rock where they must B-DaBattle them in order to save Chrome Zephyr from a pillar of ice. If Yamato and Bull can't defeat Wen and Li, Grey will lose Chrome Zephyr forever. But things get a lot more difficult when both Wen and Li combine their B-Damans to form Bakurekuso.
