It doesn't seem like it gonna end for some reason it feels like we are getting arc and new villians probably a one for all restoration
Definitely feels like the set up for a whole new arc. Depending on how Horikoshi plays this I feel like MHA could end up wearing out its welcome real quick.
Comparing MHA to Bleach, though Bleach made a resurgence in recent years, after Ichigo beat Aizen there was a really big drop off in viewers, and the quality of the series has also dropped more and more up until the series got its (cancellation) ending.
I feel like Horikoshi could end up going down the same rabbit hole as Kubo with Bleach. Just like Kubo, Horikoshi is constantly getting sick and having to take breaks, and though it doesn't seem to have affected the quality of MHA yet, who can say for its future.
I feel like this arc (if it does become one) will probably be the MHA equivalent to the Fullbringer arc from Bleach. Just like Ichigo had an arc to regain all of his power, I expect we'll see one for Midoriya. Not that I expect him to get OFA back, but perhaps this could be him finding ways for him to continue on as a hero. Which could either go the route of him going full Iron Man like All Might, or perhaps he's able to gain a new quirk to replace OfA.
