Reborn Vampire: Starting with the Judgment of the Bully

I died and I lived again. In this life, I am reborn as a boy who was bullied to death. I discovered that in this world, there are no gods, demons, or extraordinary beings. I am the only exception! But the evil in this world is so rich that it is outrageous! School violence, rape and murder, bullying of orphans and widows, burning, killing and looting can be seen everywhere. In this case, it will be up to me, a creature that should belong to darkness, to bring you real light. When the law cannot bring justice, I am justice! The moment you commit a sin, you are no longer human, you are just my food!
