"The young king of the Yo-kai. He is curious and positive about the human world, and often visits."
Yo-kai Medallium biography
"The true power of the underworld has awoken within Lord Enma. He is now able to see the going-ons in every single dimension, and the might of the forces at his disposal has become truly overwhelming."
At some point after King Enma died, the current one became the new king of the Yo-kai. He also happens to be King Enma's only grandson. Lord Enma is a humanoid Yo-kai with ruddy skin, amber eyes and spiky blond hair.
Just like his predecessor he wears a Royal traditional attire red in color with the end of the sleeves maroon in color, and attired with maroon-colored shoulder pads finely crafted with gold pieces, which are connected at the chest by a golden ornament, as well of a dark blue pad sported on the waist and crafted with gold, fastened with a maroon sash.
On his awakened form, Enma's hair becomes more spiky and turns white, his pupils become white and grows a third eye at the center of his forehead. His robes turn purple in color, his neck is now porting a flame-patterned flute linked to a Yo-kai Watch Dream. a gray and blue hagoromo goes over his shoulders all the way down to his knees. his waist becomes adorned with a series of golden framed, blue and green pad pieces and his boots are yellow instead of black.
His human form has tanned skin, but of a more human shade of brown, with dull brown eyes, and black hair that retains its spikiness. While dressed in a more casual manner, he does retain a penchant to wear ornaments.

Yo-kai Watch 3

To obtain Lord Enma's Awoken form, one needs to link together all 3 Yo-kai Watch 3 games.
Despite Nurarihyon's actions of severing ties of humans and Yo-kai in M02, Enma still has him as his servant, and they promised to make a better world for humans and Yo-kai together. In the third movie, they seem to be returned to be friends.
Lord Enma is based on Yama (or Enma in Japanese), a deity of Hindu origins introduced to Japan by Buddhist monks; a dharmapala (wrathful protector of Buddhist precepts) and judge of the dead said to preside over the underworld and the saṃsāra, the cycle of death and reincarnation. He appears as an imposing, ruddy-faced man with a pitch-black beard and a menacing scowl, dressed in the garbs of a Tang Dynasty government official. From his seat he examines the sins of each soul, tests their virtue and sends them to their final destination, and has many demonic servants to carry out his orders. His most prized possessions are a scroll with the name of every soul on earth and the Cleansed Crystal Mirror, which reflects a person's past in perfect detail. Strict and pitiless in his judgement, parents would often invoke his name when scolding children, saying "If you're lying, Enma will pull out your tongue!"
In Japanese Buddhism, Yama is believed to be an aspect of Jizō (Kshitigarbha in Sanskrit), the compassionate bodhisattva who protects children and travelers and vowed to never ascend to Buddhahood until every soul in Naraka is saved. This reframes Enma's mercilessness as Jizō's secret kindness, intimidating mortals and putting them through trials to spare them the sorrows of Naraka in the first place.
