The Garden of Sinners Collection

Set in Japan predominantly during the late 1990s, The Garden of Sinners follows the story of Shiki Ryougi, a teenage girl raised as a demon hunter who acquired the "Mystic Eyes of Death Perception" after surviving a fatal accident. It also chronicles Mikiya Kokutou's unwavering efforts to get closer to her when they were still high school students and their adventures later on in dealing with supernatural cases as investigators for Touko Aozaki's detective agency, Garan no Dou. This is set in an alternate universe to Tsukihime and Fate/stay night in which it serves as the prototype for both series as well as introducing many of the concepts prevalent within the latter two.
