Aoi Futaba (双葉 アオイ Futaba Aoi) is a teenage girl who worked for the Immigration Bureau of Japan as one of their top agents before helping save Eris. She is now seen as a traitor so she lives at the Catian Embassy under its diplomatic immunity. She has the ability to teleport objects to her that lie within a 50m radius. Because of this ability her parents threw her out, leaving her to grow up on as she says "the other side of society". She has a noticeable crush on Kio due to the fact he is the only person who ever treated her like a normal girl, but feels he would not like her due to her ability and is too shy to attempt any of the ideas Manami suggest to "get him" (such as suggesting pushing him to the ground and giving him a big kiss). In the anime, she drives a blue Ford Shelby GT500 equipped with hidden gadgets such as a smokescreen and capture net. Due to Manami's suggestion, she changes her way of addressing Kio, from "Kakazu-kun" to "Kio-kun" (which in Japan signifies that one is close to a person). She finally kisses him on the last episode, after Elis reveals due to Catian law they could all be Kio's lovers. She is voiced by Kana Hanazawa in the japanese version and Monica Rial in the English dub.
