To parry an attack, hold [Block] just as an enemy is about to attack at close range. They should recoil after their attack lands, indicating that you have successfully parried that attack. Some enemies, such as Daimyo, and Kuma, have a shimmer on their blade that lets you know when to begin parrying. Note: Some enemies, such as Bosses or giants with clubs, cannot be parried.
After parrying an attack, immediately press [Jump] to pounce on the enemy you parried. Pressing [Jump] by itself will make Afro jump off without doing anything further. Pressing [Jump] while holding the Left Analog-stick in any direction with make Afro throw the pounced enemy in that direction, where they should die when they land. You can also press [Light Attack], [Heavy Attack] or [Kick] to have Afro perform an execution move. Note: Some enemies, such as armored Samurais and electrified Androids cannot be pounced, and Afro will be damaged in the attempt.
