-Eto regrew her lower body
-Kaneki regrew his hand
This just about all but confirms that limbs can be regrown now.
-Kaneki has Etos kagune
There are eyes and a spike on his kagune now, which is from him eating Eto's kakuja. Not a big shock considering what the hell shes made of.
-Kaneki is now referred to as a Death God
The same as Arima. Interesting correlation, no idea what it'll mean but for now it's something to note.
-Kanou is experimenting with Shirazus body
Sad but note worthy. It wouldn't surprise me if he came back as a half or full ghoul due to Eto giving him a "bone" and he's somewhat similar to Noro. However, should he cross paths with Kaneki at this point, I don't see him being an issue.
I think this is the final chapter and we're on break till next year. There may be one more, but I don't know the dates entirely. Overall, I enjoyed this. We got answers to Eto and Tsukiyama faster than anticipated and we know that Kaneki has his own squad now.
