Feudal Japan

FINAL WARRIOR: Lord Kurosawa Hayashi

His serrated blade kills Daiichi"s horse, and forces him to fight on the ground.
The man goes for a standard overhead slice, but due to the agility of the Okami prince, he escapes unharmed
by dodging. During the dodge, Daiichi finds that the lord's metal armor is heavy and that he's fighting real close to the river.
He also finds that the lord's nearly turned around.

What does he do?
