(F/n)'s parents, who died in mysterious circumstances when she was young, were old friends of the Wagner family. Charles and Nancy Wagner insisted on (F/n) to stay with them.
But, (Y/n) was secretly an Anti-Christ. Daughter of Satan. Her family was also well known just like the Wagner family.
She then meets another Anti-Christ, Son of the Devil. He was also the son of Charles and Nancy, Lucius Wagner.
When they first meet, they weren't very fond of each other. A wall of hatred was built between the two.
But after a while of getting along, maybe the wall of hatred between the two will break down. And once it breaks down, they will finally see who they really are.
《If you have ever played/watched Lucius, then you might know that I don't own any of the characters. And to those who aren't comfortable with this because of their religion, don't read.》
