Inspired by a post on The Fanfiction Forum, re: Bleach chapter 651.
[Well, they have the rough equivalent of the Christian god in the soul king, and his son, Quincy lord, and talking hands. Plus they have a sword that can kill divine beings... whatever that means.
So yeah, Shinto gods probably exist in Soul Society, and they're not giving a shit about any of this crap that's currently happening.]
Hachiman: ... Shouldn't we be getting involved with what's going on in Seireitei? I mean, that Quincy guy's really close to reaching the Soul King...
Amaterasu Omikami: Let me ask you a question: when's the last time that guy invited any of us to one of his parties?
Hachiman: ... well, it emhas/em been a while...
Amaterasu Omikami: Exactly. And when was the last time he got any of us a birthday gift?
Hachiman: ... I can't remember...
Inari Okami: The last time I saw that guy, he stole all my booze!
Amaterasu Omikami: See? Fuck him. Let his little soldiers deal with what's going on. That's their job anyway.
