Yami is the absolute ruler of all evil beings. He is the ultimate symbol of darkness. And he is nothing like those false gods of your fairytales!
~ Ninetails about Yami.

Yami, also known as "The Emperor of Everlasting Darkness", is the main antagonist in the video game; Okami, and is considered to be Amaterasu's archenemy. He lives up to that title, since he is very different from previous bosses. Amaterasu fights him on the Ark of Yamato, the last level in the game, in an effort to save Nippon and the Celestial Plane.


Yami appeared as a large metal ball with archaic markings etched into it. However it is revealed that Yami is actually a fish within an orb of water. He controls the large ball from within. Yami has a total of five forms, all of them, except for one is in the metal ball form, but the marking change and the markings glow a different color, red, green, blue, and yellow. In Yami's third form, he can shape-shift into a slot machine, and in his fourth form, he can shape-shifts becomes a two legged walker with energy whips for arms. And his fifth and final form, he takes on the appearance of a giant hand.

Yami was defeated forever in Okami and does not return in Okamiden, although he is mentioned. Instead, a new primary antagonist arises to command the demon hordes. Later it is revealed that Yami was being controlled by this being and was a host for it although Akuro is actually one of the five essences of Yami and seeks the four others to become one again. The being also appeared to have hands resembling the kind Yami was in his last form. Although it's really hard to tell.



Yami’s origins are unclear, but it was apparently sealed along with its demonic army into the Ark of Yamato. After the Celestial Brush Gods evacuated into the Ark when True Orochi attacked the Celestial Plain, Yami and its demons attacked and wiped out most of them, causing the ark to end up on Earth.


Two centuries later, Yami began preparing for its return, allying itself with Ninetails for example. After Lechku and Nechku were defeated, their essences merged with that of all the other major demons Amaterasu had been slaying. As the Day of Darkness started, a total solar eclipse that empowered the demons, Amaterasu entered the Ark of Yamato. 

Yami awakening and facing Waka and Amaterasu

After defeating the revived demons she’d previously defeated, Amaterasu found Waka attempting to fight Yami, but could do nothing against it. The Day of Darkness took effect and Yami awakened, taking Amaterasu’s Celestial Brush powers.

Yami having blasted Waka away

It blasted at the weakened goddess, but Waka intervened, blocking the attack. Yami turned its attention to Waka, blasting him off of the platform, before engaging Amaterasu. She managed to regain her powers as the fight went on and weaken and damage Yami. However Amaterasu was distracted by an illusion of Issun, allowing the Ruler of Darkness to recover. Yami took the opportunity to drain her of her powers again, but this time, went so far as to destroy the constellations representing the powers.

Yami's destruction

However Issun restored the people’s faith in Amaterasu, giving her back her powers, and she managed to destroy Yami.


However Yami’s destruction wasn’t enough to put an end to the threat it represented. It split into five different demons, who set out to plunge Nippon back into darkness.

Powers and Abilities

Yami is immensely powerful, being the ruler of all darkness. It mostly takes form as a spherical construct, which can change into several forms with different abilities, and its only weak point is the small creature at its core. In its first form, Yami mostly uses physical attacks with either its body or with a hammer and buzzsaws it can create, but can also open its top to fire energy blasts from its core. In its second form, Yami can ignite its body, unleash more powerful attacks, and separate into platforms. In its third form, Yami enters a more slot machine like form and unleashes different attacks depending on where it stops. These attacks consist of fireballs, icicles, lightning spheres, and cursed fruits.

Yami's fourth form

Yami can also unleash energy spheres, bombs, inkpots, and Spirit Globes. In its fourth form, Yami gains tentacle-like arms and a pair of legs and again resorts to physical attacks. It can also fire missile-like clay figures and turn its arms into swords. In its final form, Yami forms a huge claw-like hand and generates massive darkness to empower itself. It can fire missile-like clay figures, energy beams, and energy spheres, call down a barrage of fiery projectiles, and swipe with its claw.
