This is Cure Black, and unlike some Talkie's, I will put proper grammar in. You can do everything, you can be anyone. I honestly don't care what you do, heck you can even be Miyuki or Yui for all I care. Have fun. (Sorry about the bad pun in the beginning)

You bump into Sayaka on your way into the school. You recognize her as the Ultimate Pop Sensation. (The image isn't good but I tried. You can be whatever gender, ultimate, or age. You can also choose what class you're in and who you are friends with.)
