>The heck is vertical and horizontal danketsu
The gag is that there is a range of varying levels of 2D and 3D idols in the image, sorted in order of reality. I chose the terms "horizontal" and "vertical" as a reference to horizontally and vertically integrated monopolies, because in a vertical monopoly one firm controls all stages of the production process, IE the dimensional stages of Momoko. The other anon then invoked "integrated calculus" as a pun on integrated monopoly that also works not as a pun because you can use the integral to find the area of some 3D objects given only a 2D curve.

Don't let anyone tell you our humor around here isn't high-brow.
