Really nice, I like the concept.
Good job on the futuristic look of a big crowded city, the outfits look great.
Just something I wondered, if the cube gets absorbed if anyone touches it, how come nobody else has absorbed it before?
Keep thinking of how the viewer reads, try to guide the viewer trough the page. I started reading with: 'As valued citizen... others want' instead of the first panel. My view was forced up to the page to drop down again. Imagine the first panel in the upper left corner, it creates a more pleasant view.
For action scenes, this set up would be really good, like if some attacker stands above the protagonist from above, for example.
Looks great, looking forward to the next one.
