Opiumud 044 - Kuroinu - Shen Lu Se - Di Er Zhang -opiumud- -

The original visual novel was later adapted into a six-episode OVA anime that aired from 2012 to 2018, as well as spawning light novels and a sequel, Kuroinu II ~Imyoku ni Somaru Haitoku no Miyako~ , released in 2018. With its bleak themes of submission, conquest, and mind break, Kuroinu remains a polarizing yet influential title in its genre.
