Oni of Desire

The Oni of Desire was an oni of the Shadowlands that rendered a victim's repressed desires and ambitions so powerful that no ascetic monk could control them. It affectws each victim differently, feeding on their longing for what they desire the most. It would gladly serve a mahō-tsukai targeting monks or highborn samurai, enjoying their frustration and inevitable weakness. Given form, it appeared as a geisha, befriending victims and persuading them they deserved all they desired, then reveling in their downfall.
