Nosferatu Drei -Shirogane no Tsuki o Kurau Konjiki no Legion-

"And so they surrender to the exotic seductions of the Nosferatu.
The estrum lust, the siren, of vampiric grand guignol."

Play as a vampire who trains and enslaves young women while also warding off supernatural enemies.

Your victims are devout nun Lily, descendent of witches Meg, and ancestral vampire princess Carmilla.
Raise up these heroines as part of your household! Characters grow and develop in various ways! Fight boss monsters
and clear each stage to unlock that character's sex scene.
