Wandered into the Western Fantasy Continent by Mistake! Please, I Am of Pure Oriental Descent

Am I a Muggle from another world? Sorry, your detection system is too low-end. Just as your doomsday prophecies say, I am the one who will break the situation! To conquer the four major forces, rule or save, it all depends on my thoughts! Before enlightenment, you can call me little brother; after enlightenment, you are all ants!
