After thousands of never ending genocides, Sonic has fallen into a state of hatred and insanity, using the determination gained from this to commit his own genocide, to try to match the human. Alas, Bree knew something was wrong and confronted her younger brother. She, unfortunately, was forced to commit self defense and kill her own brother. The hate was transferred into her with his LV, and her mental state heavily shattered.

It's the human's fault for all of this, and she will make sure they pay for their sins.
