It's a fairly niche genre from my understanding, especially in the magazines they have.
Bit like monster girls, loli, etc. All quite niche realistically, and the mags they publish don't exclusively publish stuff like that, so it makes sense.
As they expand and get more mags, we'll eventually get more content of the niche variety. But, till then, we've got majority delicious vanilla, with some side genres as we go
