Fratricide

Eiro looked at the figure in front of him, and slowly poured his mana into the Holy Energy Magic stone he was holding, before chucking it forward at the Imp that was running toward him. The Huge Imp simply grinned, "What are you trying to do now, throwing pebbles at me?!" He yelled out, hitting the magic stone away with little to no effort.

Just that instead of actually being able to do so, the Holy Energy magic stone buried itself in his flesh, due to the force combined with it simply being the Imp's bane. And nearly immediately, the Imp's body went into shock, like Eiro was expecting. He knew that he was a bit unique in that sense, even compared to other artificially created demons.

With a smile on his face, Eiro watched as the Imp's arm simply started melting away, as the magic stone fell to the ground. At some point, the Imp's flesh started being destroyed, and it instead healed itself, closing the wound off just a few inches underneath his elbow.
