A 2012-to-present web novel series written by Sogano Shachi with illustrations by Shikidouji in the light novel version. There is also a 2017 manga adaption with art by Hyouju Issei and an anime adaption by Passione that aired in Summer 2022. In the adaptions following the original web novel, the word dorei ("slave") was removed from the copyright's title, possibly of its negative and/or sexual associations.
