Thanks for the information, I'm especially thankful for the Keito = Ketu part. Some comments, though. The sibling gods are the Jashin (evil/malevolent god), his older brother the Kishin (fierce god, literally "oni god") and younger sister the Mashin (demon/magic god not evil spirit, it's too misleading). I won't bother translating the names.
