I want an anime style character. The character is a 1 with blue eyes and white hair. The character is the demon king. The clothes are black. The clothes are a black cape. The protagonist is with him. One with long red hair. A little bit of a hairstyle. The protagonist has a night job. The eyes are red. You can dress up your clothes. The protagonist has long hair. The protagonist has a demon outfit. The background is a starry night. A lot of magic lines. Everything is colorful. I want the protagonist's color to be a little more intense than the characters. I want the image in 4K.
