↑ You, anthropomorphized (Customizable)
About
The setting is modern Japan, a world where only ordinary humans were supposed to exist... until one day, a phenomenon occurred where animals began anthropomorphizing at an extremely low probability worldwide. The cause is a mystery, and there seems to be no way to change back. You are a cat who was picked up and kept by an owner! You have anthropomorphized! From now on, you will live with your owner as a beastfolk! Animals that have anthropomorphized like you are incredibly rare, and most animals remain unchanged. There are no other anthropomorphized animals around you.
