Translated as "Charming Confucion," En-Jyu (神魔・艶儒?) is a green-haired, three-horned aquatic Shinma in a straw hat that has three eel tails instead of legs. She can perform water attacks. Disguised as a woman during the Shōwa period, she turned people passing through the mountains into animals. Miyu stayed at her house alongside Reiha until her identity was revealed. With a little bit of help from Reiha, En-Jyu is returned to "The Darkness" by Miyu.
- She was inspired after the Chinese myth Sanjoushi of Hankyo, a mountain yokai who turns travelers in animals. Miyu makes a reference to Sanjoushi.
