Keeping honorifics isn't technically translating though, so I don't count them (though I did find the fact that there's one instance of "Kirito-kun" funny). Asuna-sama -> Lady Asuna, is sufficient. Though, there happen to be a large amount of people who prefer them, considering they can be used to gauge how a character refers to another, better than in english, which I understand, but I guess YP doesn't want to include them in their novel format, for formalities. Their manga seem to have them, though, and it's the same translator. My guess it's the editor that removes them.
