[@LeeRoy], maybe to get rid of his staff for the rematch, Ruchette reveals a new technique of creating a limited quantity of super tough diamond from her soul's ki, a diamond powerful enough to block even his staff, and the collision knocks both of the objects away from them off a cliff. This could happen at the start or even later on if he's cocky and not using the staff until later and she's forced to use her special diamond, although she'd only know the staff was that powerful to need said diamond if he reveals it.

I'll draw her during the weekend unless I procrastinate. She may develop into a more used character than originally planned depending on how things go.
