Zettai Ryouiki is a Japanese slang term for the flesh visible between a girl's skirt / shorts and the top of her stockings. This area, also known as the absolute zone, is believed to be the area that mens' eyes travel to first, and is also considered quite moe~ :3c
For the most part, this blog will be sfw, with mild ecchi being posted every once in a while. I believe subtlety is the best part of it.
This tumblr is dedicated to the absolute zone~! And stockings in general~ <3
