AU where Alhaitham has bull horns and a tail!!! Saw it on anime-grimmy-art on tumblr.

Did it for myself, so if you don't mind, you can advise me to correct something.... Also, I'm not very good at english and there may be mistakes in the text!!!! I tried to make Alhaitham as canonical as possible, but I don't know if it will work. The initial message is also free to let you make up your own plot!
