Z-City (Z市, Z Shi) is a large city within the world of One-Punch Man. It consists of a business district, a residential district, and an abandoned, trashed and deserted area—commonly referred to as the Ghost Town. Saitama and Genos are inhabitants of the latter area, which is home to many Mysterious Beings, but has cheap rent. It is rumored to contain an incredibly powerful Mysterious Beings.
Z-City has the greatest percentage increase in monster appearing in the last ten years.
Z Police StationEdit
Shelter Nr. 7Edit
Shelter Nr. 7 is a public shelter located in Z-City, built by the Hero Association in the event of an attack by Mysterious Beings. Externally, it consists of a giant dome lined with circular vents, which is able to withstand anything from extreme temperatures to missile attacks.
Shelter Nr. 7 very much resembles a sporting venue, with at least seven different entrances meant to accommodate large crowds. It was designed specifically to repel Mysterious Beings, and features biometric authenticators at each entrance to detect any possibly masquerading as human; once the shelter's defense system is active, all entrances are sealed and locked.
The interior of the shelter is largely open space, with rafters overhead installed with sprinklers and speakers to spray negative ions and play classical music, respectively—both meant to calm its likely-panicking evacuees.
However, Shelter Nr. 7 does not feature any restrooms, a rather glaring oversight given its enormous capacity.
An area where Bang trains his disciples, but one, Garou, beats some of the disciples, and leaves the rest too scared to go back, and quit. The only remaining disciple is someone named Charanko.
Hero Association Z BranchEdit
Summer Festivals are held here.
The east area of Z-City contains the uninhabited zone or also known as Ghost Town. A few years ago, frequent appearance of highly strong monsters caused residents to move closer to the center. There are rumors about a massively strong monster living in the uninhabited zone, causing fear to civilians and closing the area off from the public. However it is also where Saitama and Genos live, as the mysterious beings pose no challenge to their tremendous strengths.
There is also rumours of an elite gathering of monsters for a secret purpose.
The Subterranean People lived underground of the uninhabited zone
It is also where the Monster Association headquarters are located.
