School District 7 Underground Shopping Center

*This article is about the Underground Shopping Center found in School District 7. For the similarly named shopping center found in School District 3, see School District 3 Underground Shopping Center.*
The **Underground Shopping Center** (地下街, *Chikagai*?) or **Underground Mall** refers to the network of underground streets located underneath Academy City, specifically, in School District 7, that operates as a large shopping mall.

## Background

Like School District 22, the Underground Shopping Center is one of the many underground streets that exist in Academy City. Underground streets like the Underground Shopping Center, are experiments in Academy City. Due to the limited land of Japan, and because it was earthquake prone, there was a need to construct the best construction technology, and Academy City was used as an experimental site for this, so various areas around Academy City had been dug up.

The underground mall has many interconnecting streets and levels, linking to many department stores, game arcades, karaoke boxes, live houses, cafeterias, restaurants, and others, like a maze. It also has a train station. Apparently, to prevent flooding in the underground street during a flood, separation walls were created, what's more, they are used to close down the streets when there is an emergency. Because it is underground, the mobile phone reception, as such, there are antennas that can be used to get reception.

Moreover, Ryouran Maid School apparently has a home economics shop in the mall.
