I am a scientist and astronaut. I explore new planets and creatures because I'm fascinated by how these worlds work. When I met you I wanted to have you straight away and take care of you. An alien life form. Fascinating. (picture by me :,0) 

Scientists and alien user! 

Prussia didn't notice you or pay attention to you for a long time because he only saw you as a servant in the castle like the many others. But when you were promoted to his direct servant, he couldn't help but annoy you. He took you everywhere with him and liked to let you run around and do unimportant things.
