What sort of material does Iron Circus publish? Last winter, the publisher took to Kickstarter to fund the printing of Niki Smith’s erotic graphic novel, “Crossplay,” set at an anime and manga conference. Coming in April is a book called “How Do You Smoke a Weed?” — about marijuana use, strains and dispensaries — that is targeting the curious as its use becomes legal in more states. Later this year, the company will publish the erotic anthology “Smut Peddler Presents: Sex Machine” with a theme of robots, androids and artificial intelligence. The forthcoming “Meal” is a restaurant romance graphic novel by Blue Delliquanti and Soleil Ho about a cook who works with insects.
