The city has found unfortunate fame since the tragic Wadatsumi Mass Vanish Incident ten years ago, leading to the area, now known as the Restricted Ward, being sealed off to the general public. Since the event, the city has become peaceful, with little drama or excitement; that said, local thugs still populate the area.
Under the city, there is a network of tunnels built for the sewer system. The whole structure resembles a maze. Most tunnels are not mapped, so little is known. Fans of urban legends believe there is an underground city.
Notable locations include the Hakuō North Academy, the New Yokozaki City University Hospital, the New Yokozaki City Hall, and the Maha☆Raja~ Curry Shop. The city itself also has a port, suggesting that it is situated next to the sea.
