Made during the pinnacle of popularity for the ecchi genre, Seikon no Qwaser took things further than any anime TV series had ever dared, before or since. No other anime comes even close to having the total amount of nudity that SnQ had, all the more impressive considering this anime had an actual story to tell.
Looking back, it’s kind of amazing to think about how Xebec unleashed both Kanokon and To Love-Ru on the unsuspecting anime fanbase during the same very same anime season. Kanokon is probably even to this day the most extreme ecchi series on BD, and while To Love-Ru was far tamer, it would spawn sequels that would eventually push the envelope for the genre.
I honestly figured SILVER LINK would be one of those companies that would never ever do nudity. I think it’s pretty cool they were willing to leave their comfort zone a bit and appeal to a different sub-section of anime fanatics.
