Under the training mode, you'll find the tutorial. As the description states, you'll need to do the "stylish" and "beginner" tutorials. Thankfully, you don't have to actually complete the tutorials to unlock the trophy. Once the first tutorial begins, press pause and go in to your button settings. Make sure FN2 is assigned to any button and simply press that once the lesson starts. This will end the lesson, automatically completing it for you. Press Options to skip text and whatever button you assigned F2 to skip lessons and this trophy will be yours in no time!
