Naamah is a member of the Qadištu, and as such appears only in the Canon of Vengeance.

Naamah first appeared to the protagonist and Yoko Hiromine after dispatching an Angel that was near the ruined city of Kamiyacho in Da'at: Minato, transporting them into an alternate dimension filled with bones and blood that's later named the Serpent's Grave, then attacks them, intending to other them as a sacrifice to the Great Mother. After being repelled by them, Naamah returns them back to Da'at.
