Mirumoto Hitomi duels two characters.

The two characters opposing Hitomi "win or lose together" (as per D.6 Modify dueling statistic), and they win the duel.

Is this a single triggering condition (after your character wins a duel), so Proving Ground can react once?

Or does each character create a separate triggering condition?

Each of your characters has won the duel, therefore Proving Ground will trigger twice.
