In an era when all Evil Dragons had been exterminated, only Clone-Kuvarah had survived. He had continued training himself all along, eventually reaching the Heavenly Dragon level.
Although Azi Dahaka and Apep were also the strongest Evil Dragons, on par with Clone-Kuvarah, they had been destroyed long ago and only recently resurrected by the Holy Grail. Logically, they should not have had as much time as Clone-Kuvarah to train themselves and reach the Heavenly Dragon level.
However, Noah was certain.
Leaving Apep aside for the moment, Azi Dahaka had definitely reached the Heavenly Dragon level.
At the very least, the strength Noah sensed from Azi Dahaka was absolutely on the same level as Clone-Kuvarah.
Since Clone-Kuvarah was at the Heavenly Dragon level, Azi Dahaka, who was on the same level, was naturally at the Heavenly Dragon level as well.
As for exactly how Azi Dahaka had reached the Heavenly Dragon level, Noah could more or less guess.
—The Holy Grail.
That Longinus capable of overturning the laws of life had altered Azi Dahaka.
The proof was that Noah could sense that Dragon Slayer's ability seemed ineffective against this Evil Dragon.
Dragon Slayer was an ability that could inflict tremendous damage on dragon-type creatures.
An ultimate Dragon Slayer like Samael's could even draw upon Ophis's power and affect the Infinite Dragon God.
Thus, Dragon Slayer was practically an inherent weakness of dragonkind.
Yet Azi Dahaka no longer possessed that weakness, proving that the Holy Grail had altered this Evil Dragon and eliminated his weakness to Dragon Slayer.
Using the Holy Grail's power, Azi Dahaka had become a creature without flaws.
That was what the vampires who had once colluded with the Khaos Brigade had always pursued.
