Instinctive Reaction for Saints

[AerrowStorm1]

We actually have a few examples of Saints, while unconscious or without conscious thought moving and fighting

Here, we see Aiolius shielding Saori and continuing to walk while unconscious

Here, Marin defeats Hound Asterion with a "Completely blank" mind

Finally, we have an unconscious Seiya kick Harpy Valentine with "hundreds" of kicks while unconscious and kill him.
