The Master of Order had spent some of his energy on saving the God of Aristocracy and was thus unable to defend against the God of Light's fists.
The God of Light managed to hit the Master of Order with full power, causing the Master of Order's body to lurch with silver-white blood flying in all directions. What was worse was that, along with this attack, the God of Light's powers finally managed to find a loophole, and he used this newly created wound to encroach upon the Master of Order's body.
To someone who was a part of the great Divine Powers, such an attack almost fully guaranteed victory at this point in time.
