This is my oc, Aiko! In my scifi/fantasy story, Legacy of a Star, she's a fictional character that's widely popular throughout the universe. She has several different styles for her appearance, but her most well-known look is this cute chibi astronaut.

Rigel used to watch the series that Aiko starred in of when he was younger. He's still a fan and has merchandise of her and the other characters from the show.
