Western Fantasy: the Magician Is Reincarnated into a Monk

In this world where other races are treated as slaves, I, the Great Mage, am regarded as a devil by humans just because I helped a foreign race. When I was forced into a desperate situation by the brave group, I had no choice but to activate the unfinished "Time and Space Return" spell. Just... What's going on with this stupid face... Where are my perfect facial features? Did time and space return still fail? Is that why you time travel to this inexplicable guy?
