"The young great king who rules the yōkai. He has a great interest in humans, often transforming into a human form to wander about and enjoy himself. He is optimistic about the exchange of humans and yōkai, without being held back by the intentions of his predecessor."
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.
