This is the HSB-TOKA Corporation's main headquarters, it's massive.
You know what else is massive? Ads!!!

HSB-TOKA is a giant corporation in the 2SE, They hold some of the goverment, military, and the usual home appliances. They make fighter jets, ridiculous AI stuff, nuclear reactors, build cities, electric tools, mining things, and more.

This is a 2 Kilometer tall building located in the 2nd Segregated Empire's Capital; Tosontsonyr, the same city the Skytree Eysia was built.
It is a gigantic tower, with massive air vents to cool the huge data centers it holds, reduce drag to stop this building from collapsing, and 4 base pillars so massive it could've been an apartment.

This tower has one dominant thing: a gigantic screen, for what? For ADS!, of course.
It's fake ads but yeah, every night cycle there would be one new ad. Don't worry, they aren't paying you to display ads, they just... Add tax income, I guess?

I think that's the main attraction...
