Satania's Brother

The demon lord Satania has a younger brother who is also a demon. He has red hair and is just as mischievous as his sister. He loves to play pranks on people and cause trouble. He is also very strong and powerful. One day, he decided to go to the human world and cause some trouble. He disguised himself as a human and started causing trouble all over the place. He even managed to get into Gabriel's school and start causing trouble there. Gabriel was furious and tried to stop him, but she was no match for his strength. He eventually got bored and decided to go back to the demon world. He left a message for Gabriel saying that he would be back someday to cause more trouble.
