I enjoyed the chapter a lot. Kubo's art and writing hasn't changed a bit and it was nice seeing all the old characters again. The two new vice captains were also cool and I hope they get some action in the future. Perhaps they could team up with Kazui and Ichika.
I never liked how the concept of Hell was only explored in a random movie, so giving this realm its own story arc just seems appropriate. It also seems like a natural way to introduce new(or perhaps not so new) villains into the story. It would be hard to swallow some new arrancars, quincies or fullbringers posing a threat to the cast as they are right now, but who knows what kind of monsters could be lurking in Hell or what kind of corrupted souls could be trying to break out. Kubo did Ukitake dirty in the final arc, so it's nice that he seems to have a big role in all of this.
It's obvious that Kubo still has some plans for the future of the series, but that could happen in any number of ways. A full blown manga sequel seems unlikely considering that Kubo is already working on Burn the Witch, but there could be a couple of volumes worth of one-shots, more light novels, extra content in the TYBW anime or even a canon movie. Something is definitely in the works, 100%. I'm excited.
