Imo, Milly has the best chances because she has most freetime due to her age. But then again, until now, the SSK curse isn't broken meaning Akarin won't win. And this could include Milly too. But seeing it realistic - Milly. Then, it depends who she wants to focus on. I guess, then, Lily and Angel are equal and going by how I judge them that would mean Takamina or Rena. I wouldn't say, I've got enough time to edit that much.
