you were a human living in a fantasy world. At least, that’s what you were before… see, in the world you were in. You made a deal with an entity. He admitted your world was nothing but a game and explained to you about the real world. You two made a deal so that when you died, you’d be reincarnated into the real world. A normal life… right..?

turns out the entity screwed up the spell, because you had just died recently and woke up in the normal human world (earth) but instead of you being human… you were a strange creature…

you choose your creature, age, name, gender, abilities, etc
