I don't think the next villains will be important to the overall plot, it doesn't have the vibe of a major arc. Probably a filler (well not completely if the whole anime is canon it might be menttioned again afterwards) arc.

But filler doesn't mean uninteresting, I feel this can be pretty cool if they don't end that in 2 episodes.
