Kuzu no honkai is an underrated masterpiece. Portrays the dark side of human desires in plain sight without hiding anything. The only one and cute character in the series Moka is used as a comic relief with the author stating how pathetic it is to have happy go lucky perspective on human relationships. Akane-sensei is one of the best written female characters in recent years. The only thing that bothered me was the over abundance of sex scenes.
