Juukaze City

Juukaze City (十風市 Jyūkaze Shi) is the city where the anime/manga takes place. It is popular for its supernatural and magical citizens and also the technological achievements that were acheived here. It has a population of six million people and was established in 1842. The city's name literally means "ten winds". This was due to the ten winds in the city when it was being built. This made it hard to walk, since you were literally being pushed around by ten winds. Fortunately, those winds have calmed down now.
