Macross Corporation:

The Macross Corporation was moved to the center of the city by Ymir Terran after she took the company over from her father. The corporation was once the big bad for many, but Ymir worked hard to turn it into a force for good by making it the main Corporation that ran the other 6 Corporations through Macross.

After Ymir went missing, Macross CEO rights were transferred over to Luciana Elisheva, her sister Elleanor Elisheva, and Ylva Terran. This made it so that the President Jack Rodriguez could not take the company from them like the other Corporations.

Macross specializes in military tech, spirit tech, magi tech, ship tech and more. Due to them having run all the corporations, the Corporation knows how to do everything and has the capability to put their resources in whatever direction it needs to do. It also has the ability to power a shield generator to protect the planet - though it misses the spirits to do so now.

It also has maps of the entire city, a good relationship with the police even though they no longer run them, such as Jiasco. They also have their own private force to help protect them from hostile forces.

By being located in the center of the city, they are at the heart of the city - a location the President wants desperately. They also have acccess to the tunnels undeneath the city since they have no slums under them unlike the other Corporations being in the center.
