I know you'll argue that Sacred Gears can only be "naturally" possessed by humans and human hybrids, and that the story has used terms like "soul of a dragon."

But that just means that it's a soul that originally belonged to a dragon.

Beings are born with the same life force and essance as any other being, but what makes them unique is the powers, abilities and qualities the being aquires during its life.

Another way I could say this:

A devil and a human each have a soul. Devils possess Demonic power, so their souls are "saturated" with Demonic Energy, making a "Devil Soul." Humans however, aren't supernatural by nature, so they have a "generic" soul (with the exeptions of Holy Sword wielders and Magicians).

So in the case of Reincarnated Devils, their bodies (while keeping their original shape and anatomy) are transformed into actual Devil bodies and any magic energy they possess is turned into Demonic Power. And since God is dead, any qualities like the ability to wield Holy Swords or Sacred Gears (which are "attached" to the soul) are kept intact. So their soul is effectively turned into a "Devil Soul."
