YuYu Hakusho Wiki

Enki as he first appears.

Enki is a large human-like demon who is both muscular and fat. He has yellowish-brown hair and goatee beard, reddish skin and two drill-like small horns protruding from his forehead. He wears a white tank top and blackish-bluish jeans. Even among other demons Enki is large, standing around ten feet tall. In the manga, his body is smaller and less muscular, his face is wider and more square shaped, and his hair is black and curlier. Ultimately his manga incarnation appears a bit more "cartoony".


Enki in the manga

Unlike many demons, including his wife for that matter, Enki is surprisingly laid-back. He is very honest, honorable and polite, which is in stark contrast to almost every demon seen. He treats his opponents with respect and courtesy. However, this is not to be confused for naivety or foolishness as though not much was seen of him, he showed a very high level of intelligence. Enki is also very patient, seeing as how he is able to put up with his overbearing wife, Koku. Despite his reserved personality, he does become hot-blooded at the prospect of a fight.


Three Kings Saga[]

All Raizen's Friends gathered for the Demon World Tournament.

After the death of Raizen and the announcement of the Demon World Tournament, Enki and his feisty wife, Kokou, arrived at Raizen's kingdom in order to pay their respect to the deceased king. They also saluted Yusuke, Raizen's son. Following the arrival of several more of Raizen's old friends, Enki revealed that they all came out of seclusion in order to participate in the upcoming tournament, all vowing to make the tournament so brutal and tough that Raizen would roll over in his grave in jealous rage. In a show of power, Enki and the others simultaneously powered up their energy, creating a spectacle visible as far as Yomi and Mukuro's kingdoms.

Enki with his wife Kokou

Though none of Enki's fights are directly shown, he is seen nonchalantly smoking his pipe on top of a pile of his defeated opponents during the preliminary round.

After Yusuke's loss to Yomi, it is revealed that Enki defeated the weakened Mukuro in the final round. As a result, demons were obligated to leave humans in peace, as per Enki's new law. Enki also stated that his position of power would last only three years, at which point a new tournament would take place.


In the manga, Enki is shown to be a somewhat lazy ruler, usually seen in bed relaxing next to his wife. He is also seen attending Koenma's party.

All or Nothing

Enki and Kokou in the All or Nothing special.

In this OVA, Shunjun appeared before Yusuke. When a radical Spirit World religious sect took over the Gates of Judgement, and both Koenma and Botan have been held hostages, they demanded that all demons leave the Human World. So, Yusuke called Demon World ruler Enki and requested his help. While Enki was unable to help directly because of his bad back, he was able to use his power to coerce Hiei into aiding Yusuke. Hiei vowed to win the next tournament.

Powers and abilities[]

Though not much of Enki was shown, he is one of the strongest demons in demon world. He is an Upper S Class Demon. Yomi in particular, commented on his power as being very close to his own, however, Enki himself admitted he, as well as all of Raizen's old friends, were out of practice. He beat out all of the other demons in the Demon World Tournament including Yomi and Mukuro, though Yomi was extremely weakened from Yusuke, while Mukuro's expended a lot of energy in her fight with Natsume, and the tournament itself was light hearted and friendly which had made her weaker because she was not filled with hatred.
