Akari Oborodzuka's wrath

This girl in the drawing is from the song series 鬼蜘蛛と狐ノ獅子と (The demon spider and the fox-like lion). She comes from the song 狐と鬼の話 (Kitsune fox and demon story. [Please listen at your own risk, there are many, many TWs (These TWs include: Cannibalism, Blood, gore, Torture, profanity, strong sexual themes, slavery, violence, and graphic themes), it's so catchy but it's possibly the darkest song I've ever listened to, and I've listened to quite a few]

the summary (TWs are mentioned above^^^) :

------------------------------------------

So basically The Oborodzuka clan and the Shishikusa clan (a different main clan) were in constant conflict. A woman named Ryou Shishikusa kidnaps Akari, And tortures her in a theatre for the other Daimyo's pleasure and entertainment. Ryou tortures her brutally while also, finding pleasure in said torture, eventually killing Akari, but right before Akari dies she curses the Shishikusa bloodline, so that they will all be violent cannibals, the first victim to her curse being Ryou's Daughter, Mai.
