Shelter Nr. 7

'''Shelter Nr. 7''' is a "fortress for protecting humanity". It is a public shelter located in Z-City, built by the Hero Association spending a vast sum of money, for the event of attack by Mysterious Beings.

Shelter Nr. 7 very much resembles a sporting venue, with at least seven different entrances meant to accommodate large crowds. Externally, it consists of a giant dome lined with circular vents.

Features
The shelter was designed specifically to repel Mysterious Beings. The exterior can withstand super-hot temperatures, and absorb all manner of impacts. Tanks and Missiles are powerless against the shelter's impregnable walls. The main entrance has a biometric identification device that can even detect monsters disguised as humans. The overhead sprinklers disseminate a negative ion mist, and soothing classical music aids relaxation to relieve the evacuee's stress. Once the shelter's defense system is active, the exit is sealed and locked.

The interior of the shelter is largely open space. The overhead sprinklers disseminate a negative ion mist, and soothing classical music aids relaxation to relieve the evacuee's stress. Once the shelter's defense system is active, the exit is sealed and locked.

However, Shelter Nr. 7 does not feature any restrooms, a rather glaring oversight given its enormous capacity.
