#045 of 2D Dream Comics. Some old source may indicate it #071, that is due to some change around 2008 by the publisher, the whole 闘姫陵辱 series numbers were removed from 2D Dream Comics to form a parallel label, so this may be a confusion for early 2D Dream Comics. The number system became stable after #080.

This is the sequel to this book, and it's the adoption of a game made by インターハート/Interheart, the cg set can be found here too. And there is an artbook here.
