‘Waramete’ was a forgotten series from the Fall 2014 season, but it ended up delivering a fairly substantial amount of nudity on blu-ray, particularly in volume five.
Blade and Soul is based on a Korean MMO of the same name. Game adaptations have tended to shy away from nudity in past, which is what made the service here a pleasant surprise.
While not a true ecchi series, there are occasional sprinklings of fanservice in this otherwise dark sci-fi anime. Nipples are sporadically shown, staying true to the spirit of the manga.
