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