Yuragi-sou no Yuuna-san is a bit generic as an ecchi series, but makes up for it with great art and tons of nudity.
In that sense, it’s a bit like To Love-Ru, which was also published in Shonen Jump and received a colored version of each tankobon.
Since there’s a high number of images that might make for a slow page load, here are the shortcuts to the full download links, which you can also find at the bottom of the page. The color version covers the first three volumes, the original version covers the first six. Original | Color
