Asuka 120% Secrets?

Does anyone know of a way to fight or use any additional or "secret" =
characters in this game? Also, what is the significance of the =
"counters" after you beat each opponent? I was able to get 126 after =
beating the game on hard without losing a fight, but it didn't change =
the ending. I swear there has to be a way to fight the principal of the =
school, or at least one of his assistants.

Any help would be greatly appreciated!
