I wouldn't mind expanding upon the cursed beast men that Sajin (And my own Hachū Bōkunō) comes from if you feel it'd fit well enough within the project (The basic idea is that Yuánrǎng (Or some wholly original realm) is the "Beast Realm" that Sajin's Grandfather referred to and that their migration to Soul Society, or any other world is only permitted should they live as beasts, those that go to Soul Society are anthropomorphised [sic] like Sajin, those that go to the Human World would reincarnate there as actual animals and so on).
