I bet Shimura will be working on this one, like the fiendish vulture she is.
I'd like it if Yuri lost to Hikari. We always see rivals that are stronger than the protagonist at first (well, if you choose to ignore Harley I guess), so I'd like them to change things around a little. Have Yuri as the weaker half of the rivalry, while Hikari is always one step ahead of her. Later in the series they could build up Yuri's coordinating skills and have her completely shock our heroine in a contest battle.
In a perfect world, Hikari would rub the loss in Yuri's face. But judging from her current...um...personallity, I'm afraid this is little more than a pipe dream, spawned from the mind of a guy desperate to see tons of negativity in a poorly animated child's cartoon.
So Hikari coming out on top against a rival who acts tough but has no idea what the hell she's doing would keep that guy content.
And yes. I am aware that 'Yuri' isn't the fine young ladies' name. Sorry smartass, today is not your day!
And as a final side-note, I hope Roserade makes an appearence. Because it just isn't a contest quest without the occassional rose petal or two.
