The Spirit Realm is inhabited by the souls of deceased humans unable to move on, held back by their vice and grief. Often these souls manifest in forms that serve as a reflection of the individual's soul, based off their life, sins, and desires, with some resembling their past human forms while others are more monstrous or animalistic. Ruling over this realm are three demonic princes who serve as the embodiments of rage, desire, and misery.

The Prince of Misery is an avian humanoid with large, feathery wings normally kept folded against her body like a cloak, her face consisting of a white mask with bright blue eyes drooped downwards in perpetual sorrow. The embodiment of sadness and regret, her domain is a frozen desert inhabited by lost souls and wandering spirits. It is said that she feels the pain and suffering of all her children, and can even make people feel remorse over their past actions.
