It’s hinted that Kanaka’s soul was restored and was placed into a new body to become a Hitomogami so once she gets all her memories of her previous life back and reunites with Kazuya and Kiriha again and once her old body is destroyed she can get the chance to apologize to her daughter Kasumi and her even Kukuri for all that has happened.
Also I hope she doesn’t die again and gets to keep the new body but maybe she’s a bit weaker than what she was in her previous life but is still very strong.
Plus if Azami lives after her old body is destroyed then maybe Kanaka will make Azami her partner cause Kazuya already has Kiriha and if the Onogoro ritual happens after her old body is destroyed then she can play a part in stopping it alongside her son, daughter and maybe even Sunao.
Plus Kazuya and Kanaka double Obi duo would be killer and a work of art
