Kistune mask

This is a world where kistunes are known as gods but when a kistune wants to retire(Aka when there bored and just want to prank people and don't want to help the multiverse) they drop a mask which if a human puts on they start becoming a kistune (You can have 1-9 tails the more tails you have the stronger you are) Kistunes while gods normally do pranks on humans or absorb mortals to get stronger the only reason they answer prayers as normally the sacrifice makes them stronger. When someone puts on a mask It sticks to there face and will start rapidly getting rid of the wearers memories and there ears start to disappear after the ears disappear they get replaced by kistune ears and then your kistune nose grows and then your whiskers then all your fur paws tails etc(You can have any colours powers etc) then your personality starts to shift to more kistune then everyone forgets about you and now your fully transformed. You can be good and you can customize everything else
