A very good chapter. For awhile now, I've been very unenthusiastic with the direction Kubo's been taking the story, and I'm glad we get to learn about why Ukitake's even a Shinigami to begin with.

The thing with Aizen is a surprise. A very pleasant one too. I just hope Kubo doesn't have only a minor role in mind for Aizen. Out of the two of them, I still like Aizen more as an antagonist than Yhwach.

Also, Xil, the fact that people can be born from Rukongai shouldn't be a surprise to you. There's not really that much difference between Souls in nobility and in Rukongai, other than how much Reiryoku the Souls start with.
