Battle:
If your army has one or more unbowed Samurai and the enemy army has more unbowed Personalities than yours: The enemy leader targets and bows a different unbowed Personality in his army, one by one, until his army no longer has more unbowed Personalities than yours, or until he can no longer do so.
The mobility of the Moto gave them an early advantage, but they had not counted on the ferocity of the Matsu charge.
