A stoic, slime-like spirit in a cave under “Undine’s Spring”, out of view of the rest of the world, but also being rather intelligent and always calm, yet somewhat perverted at times. Disliking humans who pollute the waters of the world, she mercilessly preys on any who dare enter her terrain, absorbing them into her body, she assimilates their body to become one with hers. Though she dislikes humans, she seems to hold regrets that humans and monsters aren’t existing in peace as they did before.
