Yup, they went there.
Once again, props to Nylon66.
Also included were some relatively tasteful manga artwork:
So anyway, not the best nipples in the world, and not to sound nitpicky but Eco’s chest just seems a bit… hard looking? Not all boobs are created equal, but last I checked, a boob is still a boob. My petty complaints aside, this is a pretty cool development, since Eco provides a lot of fun nude moments throughout this series.
Of note, there were no noteworthy changes in episode 1, meaning no Navi nudity. A minor bummer, though hardly unexpected. No other AT-X exclusive “extra ecchi scenes” were enhanced for nudity on blu-ray, which was somewhat surprising. There aren’t any fanservice extras, which makes sense since the anime already had the added scenes, similar to High School DxD New.
