This anime was one of the first victims of the persecution versus ecchi anime (it was released more than ten years ago when ecchi anime were considered "rebel" animes). I say this because The Qwaser of Stigmata is an anime that works on many levels, but sadly, it has been a victim of low ranking.s
Firstly, It has a solid story and an excellent development of the characters' personalities. Suppose you have enough intelligence to follow a story without feeling offended by boos. In that case, you will find an incredible story with a deep background of the characters' personality and a fantastic construction of the universe in which all the stories happened.
Second, this story has a strong dose of elegant eroticism. It is the anime that touches the border anime ecchi and hentai anime in the best way. I don't understand why some people score the erotism with bad ratings. It is like under-rating a romantic story because "it has a lot of romantic moments that don't help in the story's development."
The Qwaser of Stigmata is an erotic story, and I see it as a quality of its massive doses of erotism and fan service because it is a genre!
In a nutshell, The Qwaser of Stigmata is an excellent example of balancing a good story and fan service. Therefore, I strongly recommend this anime to the fans of the genre. Although, when it comes to me personally, I have other favorite erotic animes with a good story, I see The Qwaser of Stigmata as an excellent anime.
