Well it was your typical arc closing chapter, they teased a potential showdown(rematch) between the Wizard King Chrono and the White night eye's leader, and Chrono acknowledging that there's a traitor in the Magic Knights. They also foreshadowed a rescue attempt for the captured enemies, and the future awakening of the Sleeping Lion FuegLeon.
No idea what the next arc is gonna be about, but I do want to see more of the Black Bulls. So I hope the next arc involves the members unused so far including Captain Yami. Overall I think this arc had good action, cool new characters e.g. FuegoLeon, character development e.g. Noelle's, and story progression now that we know the bad guys are.
