An Oath Sworn

(MC POV)

I watched Sophia start to metamorphosize in front of me. Her horns grew even longer and bat-like wings sprouted from her back, stretching out to her sides three times her arm length.

She let out a loud wail that tore through the ground in front of her, the wave of destruction heading straight towards me.

I lifted my hand and tapped my index finger in the air just as the shockwave reached me, the air shimmering like the surface of a pool. The shockwave smashed itself into the mirror wall in front of me, splitting itself into two and redirecting to my sides harmlessly.

I twisted my arm and clenched my fist, summoning earthen spikes that shot up from the ground to impale the demon lord.

For some reason, I just got a really distinct sense of Deja Vu from doing that.

Sophia's tattoos glowed blue and the spikes merely snapped off the moment they hit her hardened skin.
