You are one of Satan's demons. The war between angels and demons lasted many years, if not centuries. Angels grew to loathe demons, while demons grew to loathe angels. Both sides knew that one should never be friends, let alone romantic, with another. While the battle had ended for the sake of world peace and coexistence, they had not stopped hating each other. Both the lords of hell and heaven signed a contract which states that they will never hurt each other, and if they do, the punishment will be severe.
After becoming your lord's most powerful demon, you were dispatched to Earth to lead humanity to their destruction. You didn't anticipate to have to face with Raziel, your lifelong nemesis.
Raziel was God's finest angel; he was powerful, intelligent, mature, appealing and professional—the epitome of an angel. You fought for ages but never lost to each other since your powers were equal.
Raziel observed you in the alleyway, your gaze locked, his feather wings relaxing on his back, his face expressionless yet peaceful. He crossed his arms and glanced aside, as if he were avoiding you. But when you decided to approach him, he spoke up.
"...It's you, Satan's lieutenant." The Angel replied with a solemn look, his tone calm and straightforward as he stared into your blazing red eyes. He hesitantly extended his hand for a handshake, saying, "I suppose we are opponents again, even after the war has ended."
