Monica Rial (English)
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 states is "the other side of society". She also makes use of a technologically advanced battlesuit and weaponry, (unknowingly provided by the Dogisians). 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 along with Eris and Manami.
