Phase of Hate

I was a prodigy. A grieving sister. A girl falling for him.
I died, and now I'm reborn. Stronger. Deadlier. Angrier.
I'm determined to punish those that turned me into a monster. The curse kept me alive, but at what cost?
I'm at war with my nature.
I refuse to ever accept my fate.
Once a prodigy, now a curse.
Once love, now hate.
