The Witch Knight Anna -The Black Serpent and the Golden Wind-

It has been a thousand years since the wicked Genies began to appear in this world. Humans offer their “Souls” to these Genies in exchange for having their wishes granted. The maidens who battle against these wicked Genies are known as the Witch Knights.

Anna, a new member of the Witch Knights, heads to one of the Genie’s strongholds, a “Genie Mansion”, after consulting with her Master as usual. Along with her Master, Rain, they arrive at the Genie’s stronghold. However… Anna is suddenly attacked by Rain when they arrive. It turns out that Rain is actually the nemesis of the Witch Knights, Lilith, the Mother of Genies.

Anna is attacked by Lilith who has transformed into a hermaphroditic form and loses consciousness. Then… when she awakens, she is trapped within the Genie Mansion and Mami, Rain’s aide appears… already having had her soul stolen by a Genie.

Anna, who has had a magical tool called a “Mara” placed around her neck, finds that it can grant an sexual wish.

After this, she is attacked by her friends who have had their souls stolen by various Genies… Will Anna be able to save her friends from the clutches of the Genies living in this debauched Mansion?
