Because the Russo sibs are in training. I bet the Ozus forgot the basic ones. Ok so then the Ozus can wipe out all other witches, mages and wizards too, right? Well the "do you believe" thing was on Nick. Hmm... well what will the Ozu siblings feel when their parents say to them that only one can keep their magic? (it's Jerry and Theresa Russo (The Russo siblings' parents) who told Miyuki and Isamu Ozu that). I'm just putting more sense in the Toei-Disney relationship. What the heck?!?! and you told me i'm smoking too? you'd stop saying that since I NEVER DO BAD HABITS!
