Is there any combination of 3 character-types that could use every
weapon/armor available in the game?
Or is ther even more than one possible combination?

I know that I need a female Newman for "Riku's Suit".
Each Race once for the race-exclusive weapons as well as
each class once for the class-exclusive.
A male character for "Bitter Berry" and a female for "Sweet Berry".

Any recommendations?
