A single-volume collection of side stories from Tensei Akujo no Kuro Rekishi, published by Hakusensha in 2022. This anthology expands on the main series' premise of a woman reincarnated as a villainess, delving into the "black history" of her past life through bonus chapters.

It's a concise, self-contained treat for readers already invested in the world of the reincarnated villainess.
