User blog:Swordbirth18/Beyond boundaries of ecchi

As you see, some ecchi anime goes beyond the borderline ecchi like Shinmai Maou no Testament, Rakudai Kishi no Cavalry. To Love ru darkness manga goes beyond ecchi on their december chapter and accidentally showed something more outrageous aside from Oppai. As the volume of this light novel animated, it makes me wonder how they will apply this in anime knowing the fact that someday dxd series will have a mating volume whomever it may be since it was actually a mix of romance and harem..
