Sector 5 is a location in the Final Fantasy VII series. Located in lower Midgar, it is under the Shinra Electric Power Company's control. Like every sector of the metropolis, it is composed of both slums and plate sections, though the plate is rarely seen.
The Sector 5 slums are notable for being Aerith Gainsborough's adopted hometown, where most of her life is spent under the care of Elmyra Gainsborough. It is also home to the Sector 5 slums church, a church where flowers grow due to rare natural sunlight being let in. On the plate, Mako Reactor 5 is one of the reactors attacked by the Avalanche cell led by Barret Wallace.
Little is seen of Sector 5's upper plate aside from Mako Reactor 5, and the walkway outside leading towards it. The Mako Reactor 5 is accessed through an underground subway from Sector 4. The walkway is visited by the party after planting the bomb at the reactor, and is where the Airbuster is fought. Following the battle, the left side of the walkway is destroyed.
Much like the rest of the Midgar slums, the Sector 5 undercity comprises shanty homes that its residents live in alongside crags and abandoned construction material. It stands out among the Midgar Slums partly for its abundance of scrapyard piles, as well as the limited light let in allowing vegetation and flowers to grow, notably in its two major landmarks: the Sector 5 slums church, and the garden where Aerith's house is located.
The slums is home to a marketplace in its central district, located a fair distance from the Sector 5 Church, with a road connecting them. Aerith's garden is adjacent to the central district, and the garden comprises three islands by a waterfall, with a river running through them. Nearby the district, a hole in a wall leads to the Sector 6 slums, where Wall Market is located.
The Sector 5 undercity's landmarks are largely consistent between appearances, though in Final Fantasy VII Remake, the area is expanded. This includes an Undercity Station for the slums, as well as a backstreets area running between scrapyard mountains, where many monsters dwell. In the central district, the slums are also home to an orphanage known as Leaf House.
