Go to the Dojo, play Competition Mode (well, you could play on the mats, but competition mode is faster) earn all your belts. When you get your black belt, challenge the Sensei, it takes a while to defeat the Sensei, you need to play him a few times and then he will get weak. Go to the Server Mammoth and dance in the middle of the dojo for 30 miniutes or so anf u will get your black belt then go to challenge the sensei
After 3-4 games of playing the sensai, what actually happens is that the actual sensai goes away and another ordinary player comes in. only thing is that they look like the original sensai. IT IS A DISGUISE!!!!!!!!
