Debut Ninja Gaiden

Guardia de Mieux, known as the Jaquio (邪鬼王 Jaki-Oh?, King of the Devils) is a primary antagonist in both Ninja Gaiden and Ninja Gaiden II: The Dark Sword of Chaos.


A bizarre sorcerer with purple skin dressed in a red torn tunic with a Hexagram embroidered on the front and a purple skeleton of a demon wrapped around his body like armor.

A bunch of eyes are attached around his body. In the PC Engine / TurboGrafx-16 version, it has tormented faces with suffering expressions around the helmet.


Ninja Gaiden[]

After Walter Smith, a professor and acquaintance of Jô Hayabusa seals off an ancient ruin in South America, Guardia de Mieux, the Jaquio appears and takes control of the ruin. Jaquio awaits Ryu Hayabusa after he sends his assassins, the Malice Four to steal the Demon Statue and break the seal on the Dark Demon, plunging the world into darkness. After the Malice Four steal the Shadow Statue from Ryu's father, Joe Hayabusa, Jaquio tricks Ryu into surrendering the Light statue while he prepares the ritual in front of the Demon's body in an Amazon temple. He succeeds in breaking the seal on the Demon but is defeated by Ryu and the Dragon Sword.

Ninja Gaiden II: Dark Sword of Chaos[]

Jaquio is initially mentioned by Ashtar, who was apparently the Jaquio's boss all along through the events of the first game.

After Ashtar is defeated by the Dragon Ninja Ryu, Jaquio reveals himself somehow fully resurrected. He takes Irene hostage and grievously wounds the US Army agent, Robert T. Sturgeon. He soon meets Ryu in a demonic altar, and reveals that the energy of the spirit of the Demon flowed into his body after their last battle, resurrecting him, and giving him unfathomable evil power.

Despite his powers he is beaten by Ryu. However, his blood flowing out touches the cursed blade of the Dark Sword of Chaos, and it sucks the life out of Irene. The Gates of Darkness are thrown open and the revived Jaquio takes on the form of a demon. He challenges Ryu, and is once again defeated by the Dragon Ninja. After his defeat, the Sword of Chaos is destroyed and the Dark Gate is sealed, as the castle collapses.



  • In the PC Engine / TurboGrafx-16 version, the names for the character are translated differently, with the names "Guardia da Max" and the "Devildoer" being used in the English version of the game's cutscenes.
  • In the OAV a flashback shows Jaquio with the Dark Sword of Chaos on his hands.
