I've always assumed it means the story is written with a light novel flare. Often focusing on story lines that have certain elements of anime or manga. For example, I'm sure when most writers write, they are picturing real people and real places in their head. But for me, I picture anime inspired places that are based on reallife. I often see my characters as anime characters and have them act as such and move around as such. It one reason my stories seem to be under 10,000 words but are broken up in chapters. Think of each story as a episoded of an anime and each break a cut away, a chance for you the viewer to go get something to drink, fix a quick snack or flip the channel to a lot better written stories! But in short I've always seen it as a story that has characters us anime logic instead human log, like Daisy who was suffering from pneumonia and somehow still managed to dress up as a cheerleader, walk down to the morgue and engange in a life or death battle with Nurse Spooky. Anime logic.
