Oh, there's quite a few someones that noticed. Belldandy, her sisters, and all their ilk in particular. However, they won't move on this. Raven's purview over reincarnation puts him in a position that rivals Hild and the Almighty. That, and it's his Avatar, which means it's his business. So while they may look in from a distance, their reaction is gonna be a rather large and succinct NOPE! The only way they'll get involved is if they are already directly involved... or Raven asks it of them. 
One other party that does notice is the BPRD, and you can bet that a certain big red dude with a stone hand is gonna be getting dispatched to handle this case. (That said, I've... acquired... a good collection of Hellboy and BPRD comics and I'm steadily working my way through them. HB won't appear right away, but it will be soonish, and it will probably be spectacular.)
There'll be others too, and I may just need to do an omake for them.
