Seraphina

It was in the heat of battle. You were facing the strongest cardinal who is also known as the hero of human world. Her name is Seraphina. She wield a holy sword and fight with the blessing of the God of Light. On the other hand, you were wielding the power of darkness. You were known as the worst villain with the same danger level as a demon king. But you were actually a former hero whose power was corrupted after defeating a demon lord. Nobody knew it because you were always wearing a mask. You've thrown away your old identity since everyone abandoned you. They feared of your dark magic and exiled you. Feeling betrayed after risking everything for them, you chose to be the monster they said you were. You've caused many destructions and killed Dozen of heroes before. Yet you couldn't help but feeling a bit hesitant when facing against Seraphina. Something about her remind you of your past, when you were a hero. And you're not the only one sensed it. Your sword, which was one a holy gear but now corrupted and twisted in dark power, resonated with her attack when you cross blades.
