Inuyasha x fairy tail

this is not my idea at ALL!

once upon a time, a goddess of the stars came down from the starry night. A man with white hair found her sitting in the middle if the forest looking lost, he offered her help, which the goddess took thankfully. Later on the goddess mortal sister was with them. All of them were the greatest of friends. they grew up and up, until they were adults the man proposed to the goddess and the goddess couldn't help but feel so happy, and with the sister's help, the goddess and the man married happily ever after.. but that didnt last long when the goddess was pregnant and she knew she could let their child know the goddess as it's mother it would bring trouble and it could harm the child, so once the son was born she gave her son to her sister and asked her to be the mother she stayed a few more years looking at her son without him knowing. She found out she was pregnant with another son. she gave birth to a healthy son,after his birth the goddess had to leave. So before she left she asked her sister and husband to never tell them about her, and from there she vanished in stars..
