Crossbell City (クロスベル市 Kurosuberu Shi?) is a large city located on the western edge of the continent, and is the capital of Crossbell State. It was once the battleground for a conflict between neighboring countries, but has since become a thriving metropolitan area with a financial district, entertainment facilities, and residential areas. It is where the Zero/Ao duology takes place along with the majority of Akatsuki no Kiseki.
The city features what is known as the Orbal Network Project, an innovative data network developed by the Epstein Foundation. By connecting computer terminals via Orbal cable, it is possible for vast quantities of information to be exchanged. Originally, Liberl's Zeiss Central Factory was going to develop the network with the Foundation, however with an offer of funding from the IBC, a full field trial has begun in Crossbell City.
