Unlocking Omake or Extras Menu
     After  winning  the World Queen Contest, there will be a new menu
in  the  Title  Screen.  It's the most lower one called Omake. You can
make  a  new  character  here  and  play  it  in your save game. After
creating  a new character, the next time you continue, there will be a
new option. The upper one is to play with your original character. And
the bottom one is to play with your Extras character.
