Glad to see that Sajin's origin has, for the most part, now been explained in that his is a unique race within the Soul Society instead of him just being some completely random individual.

Further good seeing other divisions and how they're handling the aftermath of the war.

What certainly is curious, for me, is just what it is Mayuri is up to. For Akon to be surprised/shocked would mean it has to truly be something beyond normal (as much as that word can be applied) for Mayuri.
