first of all i am apologising for every typo i make.
this will be an idea from my head so I dont think it will be like the thing vent made.

ok when you join you can be any character.If you want you can even be someone from an anime.(but you dont have any super natural powers or anything) but your animals do.the sheet for character is basicly same as in the academy of magic creation.but you must make a sheet for your beast too. everyone when starts get 1 free animal that has to be trained (like in pokemon) the first animal can't be anything strong (ect lion or something) it cannot even be a dog.It has to be a weak animal like a bird or a cat or something.then it upgrades by traning and it can even change species, but not from a bird to a whale, ect it can be a cat then a tiger would be the top level.and then when an animal becomes dangerous there will be fights and a way of making cash and living.
So thats my idea tell me what do you think
