Nakago

魏アユル

Nakago is regarded as the leader of the Seiryuu warriors and serves as the primary antagonist of Fushigi Yuugi. His actual name is Ayuru Gi, and he was born under the star Heart.
Nakago is both ruthless and charismatic; he discards those who have outlived their usefulness to him and adeptly manipulates others into complying with his wishes. Nakago's powers as a Celestial Warrior are depicted as superior to those of any Suzaku or Seiryū warrior. He possesses the ability to manipulate chi, which allows him to exert psychokinetic force, unleash blasts of fire energy, and erect force fields. In combat, Nakago also employs a whip and a sword.
As Kuto's highest-ranking general, Nakago commands two-thirds of Kuto's army. He is the last survivor of the Hin Tribe, a people annihilated on the orders of the Emperor of Kuto. Nakago was captured after witnessing his mother being raped by Kutō soldiers; this event triggered his powers, leading him to kill the soldiers and his own mother. With the surviving soldiers identifying him as a Celestial Warrior, Nakago was brought before the Emperor, where his natural beauty led to his sexual abuse by the Emperor. As he achieved complete control over his abilities, he eventually became an apparently loyal soldier of Kuto, while the Emperor remained unaware that Nakago had been plotting to betray him throughout his life.
