A Magician with One Punch

Gandalf-style melee wizard is online! Goldfinger? No need at all, my existence is a humanoid self-propelled plug-in! Magic? Is it as hard as my fist? The magician knows martial arts and no one can stop him! You ask me how I can survive in a magic school without magic? Simple, let your fists do the talking. You ask why my brother has a black nose and a swollen face? It would mean nothing if the brothers weren't for sale. You ask me how my love is going? Hehe, this is not common sense to outsiders!
