His art is about as not safe for work as it can get. It is of a very sexual nature.
If you are under 18, at work, eating, pregnant, prone to heart conditions, a total prude, you must be this tall to ride, etc. you shouldn't look. And if you do anyways, don't fuss at me, because I warned you!
The splash page does not have anything terribly vulgar on it, but you can get an idea of the artwork to see if you want to pursue it farther.
If you want a preview of some of his work, it was just posted in kawaii_noir. This link goes directly to a bunch of uncut pictures, so all the previous warnings apply!
Mods: I understand if this isn't the sort of thing you want posted, so feel free to delete.
All that having been said, I think the art style is gorgeous. The lines have an almost baroque fineness and the colors are so translucent. The subject matter is modern and disturbing, but not violent. The yokai are damn cool, as always.
