Enel and urouge definitely need to show up this arc
Along with them I’m personally also hoping for the rest of the supernova, Kuzan, and Linlin
Yeah the surviving lunarians hiding in Elbaf definitely makes a lot of sense. Them and the giants working together due to their mutual love of joyboy/nika
Meeting them is probably when we’ll get a little flashback to what we missed from the seraphim fights
