Ame Warashi passed it on to Yuuko, and it is quite valuable. This creature has a regular form that resembles a snake, being slippery and slithery. Despite this, it loves to get inside Watanuki's clothes, climb up to his face, and caress him. It is extremely fond of Watanuki. Kudakitsune is the master of little hearts ♥. Additionally, it cannot speak.
Watanuki named it Mugetsu (no moon) because its eyes are hard to see and resemble a crescent moon when it is in its larger form. When confronted with evil auras, it transforms into a nine-tailed silver fox. In this form, it can burn things with its breath and destroy objects with its fangs and claws.
