When a master in martial arts fought, they usually described their state as a hyperstate of concentration where they can see things as if time was in slow-motion.
But that was an exaggerated description, no human mortal was capable of distorting the mighty power of time.
The hyperstate that they assumed during a fight for death was the result of their powerful bodies and enhanced senses.
Theo was a grandmaster in several fighting styles while Ayia and Shizuka were soon-to-be grandmasters, so their hyperstate was even more exaggerated.
Their bodies that went through years of training had superhuman senses capable of accessing the ultra hyperstate.
This meant that even after the lights went out and the darkness covered the room, the three of them could sense each movement of their enemies.
