Mercy? Yes, I Will Mercifuly Kill You

-----

Agate concentrated large quantities of Mana within a sphere, generating a large, rotating multi-colored jewel ball, which she charged with even more Mana!

The sphere of iridescent jewels flashed with bright yellow light, unleashing an enormous beam of holy light towards Arthur!

Arthur gritted his teeth as his sharp crimson eyes flashed with a scarlet light, a wave of black light and purple ethereal liquid emerged over his body, protecting him!

BOOM!

The black light began to absorb the holy light, and the corrosive purple ethereal substance corroded the light!

CLASH!

FLASH!

Suddenly, the holy light exploded and dissipated!

Agate was left in shock!

Just what kind of powerful barrier ability was that to completely negate her powerful beam of holy light?!

"What kind… power is that? I have never seen… black light before…" said Agate while clenching her fists.

"Why should I tell you anything? You are going to die anyway," sighed Arthur, surprising Agate!
