Kursia is a Nightmare with a humanoid appearance which has a snake-shaped ponytail.

This is not a great threat, but she has the ability to make people fall in love with her so that they do everything she wants, but also, with the help of her "ponytail", she can leave her victims petrified like statues.

Although she acts very flirtatious when she leaves her victims in love, Kursia has a more lazy and mocking personality, laughing at how pathetic her victims act when she makes them fall in love.

Her snake ponytail has a mind of its own, and loves to try anything that looks delicious for... Him? Her? (It's still under debate) the most common are flies and mosquitoes.

Both cooperate as a team to defend themselves from whoever wants to stop them, but sometimes they fight themselves for different reasons, such as the fact that her ponytail wants to eat a human but Kursia doesn't want that to happen, since she finds it disgusting.
