The enemy that hold a shield on Dogurai is called Heavy.

Usually you have to go through a QTE to defeat him, but here's a simple way to avoid it and save some time.

How to Execute:

1. Press Slide (R or Down + Jump) to slide towards the enemy
2. Release Slide and hold Backwards on D-pad
3. Hold until your character has got through

It is about 80% success rate, but it is still quicker to try again than fighting them.
