Well now you are here you know the truth in a more accurate sense (our Gods being advanced aliens).
The "main" Gods behind shinto are the same satanic ones as behind other gentile pantheons. If you mean kami in the sense of "any spirit" well spirits can be or not satanic many are simply dead humans without so they would be non-satanic.
This is just speculation by me : Izanagi seems to be Satan, Izanami seems to be Lilith, Amaterasu seems to be Inanna, Susanoo seems to be Dagon.
