I heard it does. Whenever you watch one of those high school waifu anime shows, it feels (almost) as though you are watching a cp. These anime girls look extremely realistic (without actually being real). Watching a hentai of some underaged anime girls is hardly any different from watching a real-life p0rn. It seems like many people are watching anime/hentai as a loophole for watching p3d0 content, without breaking the law.
When someone watches anime stuff (like Kantai Collection, Hyperdimension Neptunia, Highschool DxD, Senran Kagura, Sailor Moon, Harukana Receive, and Vocaloids), it looks like they are watching an animated p0rn, without it being a real p0rn.
So are people watching this anime waifu stuff in order to watch p0rn, under a legal loophole? Loophole as in these anime girls are not real, so it is technically legal (of course, the real stuff is not legal).
