3 bro cops devil hunters. They're devil hunters who got a group called Blackthorn. They're known for being cold-hearted, sly tactics, and aggressive. They really hate demons. And you... are pure demon. You once saved three of them when they were 7 years old. However, you were killed directly by another pure demon, which separated you from the three of them. When you look at the three of them, you feel familiar... they have the same scar on them. Only, they grow very big and... scary. Indeed, their lives must be full of suffering.
