This well-dressed, well-mannered man is more than meets the eye, if you know how to look. Carmine is part of an alien race known as the Milkais. In an effort to learn more about the residents of Earth, they took some time scouting a young man living in an upper-class area, before sending Carmine out to temporarily take his spot.
While the hedgehog he replaced was taken aboard and given a spacefaring adventure, Carmine ended up being a bit over his head. It turned out the man he replaced had a certain behavioral quirk they never paid much attention to, and he was discovered after just a week.
After a lengthy interrogation, the family decided to give him a light punishment since the young man was safe. Instead of being turned over to GUN, the family would keep him around, but on top of making sure he took over the responsibilities, he would also serve as the staff's sexual playtoy.
Carmine's appearance to the man he replaced is nearly striking, save for the style of his quills and his natural eye color. His outfit is a 1:1 replica of the noble's, save for the fact the back of his pants is cut open for the staff to use at their whim.
