When I touched the crystal ball, it emitted a black glow.
"Pure dark attribute, huh."
Platy nodded, as if she had expected this result.
"Darkness, huh…"
I probably had a complicated expression on my face.
"Yaaay, your magic is darkness, loser,"
Ante teased. I scowled in response.
Hello, I'm Zilvagias, the Demon Prince who, upon having his attribute tested, was found to be pure darkness.
This crystal ball apparently has the ability to determine a person's attribute when they touch it. By the way, it doesn't recognize the Holy attribute. According to Ante, that's because Holy isn't a natural attribute that makes up the world; it's more like a curse that was created by the human race. So it makes sense that it wouldn't show up.
A person's magic attribute is influenced by their lineage, species, and the environment in which they were raised.
