Eromanga Toshokan is a brand new column here at HD, launched in our continuing effort to expose just how much of a sicko Shingo is fans to an oft-downloaded but seldom deeply probed segment of Japan’s visual culture: the wild world of eromanga (no, not the Australian town). For our first entry we bring you a review of the recently released Giri Giri Sisters, the second tankoubon from doujin veteran Kisaragi Gunma. Note: this post is 18+ only and not safe for perusal at work.
