Automatically Draw Sword
To automatically draw your sword, follow the rightmost path at the fork in the 1st level. Then jump into the villain who impedes your progress by running towards him and pressing B button. (You'll jump right through him!) Now, whenever the Prince sees an enemy, he will automatically draw his sword.
