King Arthur and Master Dragon

Entaku no Kishi passed several tests and arrived to the cave in which Master Dragon lives, to save Nanobana Kinako from him and the dark knight. King Arthur and Master Dragon battled against each other. Master Dragon lost the battle and fell into the water, letting the others think she’s dead. Then, Perfect Cascade appeared to have a match against Entaku no Kishi in their Hyper Dive Mode.
