Well, I would want to spend training with Erza, but might end up with a free broken bones. Lee would be a good choice because he is really nice and I think would take it easy on you, but Guy would probably be teaching Lee how to teach me. I would love if Kakashi would teach me, but it might be a little bit hard, because he's so skilled. Oh and if Sir Melodious trained with me, I think he'll be kind of like Lee, gently and take it easy, but he'll be the one teaching you. And also, I'd like to be taught by Maka and Soul, because Soul is just one cool guy and I think it would be fun. And Maka would be easy I'm pretty sure. I would also like to train with Guildarts, but that might be a little hard.
I know I wrote to much, but I would like to be trained by all of them above.
