Hogwarts Wizard

A magician from another world (to be grown) who intends to change the magical world. Ravenclaw looked more and more like Gryffindor. Has been dedicated to the curious wizard who is on the verge of seeking death. Mature soul, childish mentality and a system that doesn't give much help. Roy Fox, what kind of legend will you create in this magical world? "Oh! How can you be so upright, Hagrid?!" "If you find it difficult to accept the new classification of spells I proposed, then just talk to me about my fireball technique!" I will reshape the magical world with a new system after the fall of the legend!
