Shinminato-ku

Shinminato-ku is the city in which the events of Taimanin Asagi Zero take place. An Alternative timeline version of the Chaos Arena and a school called Joei Academy, as well as the Shinminato-ku 6th Precinct police station exist in it.

Speculation warning
In the real world "Shinminato, Toyama" is a town founded 1951 and dissolved in 2005 being merged with other towns to become Imizu.

As Shinminato-ku does not exist in our world it is possible that in the world of Taimanin the town never was dissolved and grew into a giant metropolis.
