Underground King

His features echo those of the Washuu line, and a mole marks the left side of his chin. A kakugan shows in his right eye, betraying his one-eyed nature.

Born a one-eyed ghoul within the Washuu Clan, he came to loathe his own kin and rose against them. Eto Yoshimura frames the event as a revolt against humanity, one that supposedly moved the Japanese government to hand the Washuu Clan its authority and to establish the Commission of Counter Ghoul in order to put the rebellion down. Nishiki Nishio recounts it instead as an uprising launched while people were still rebuilding after the war, a massive clash against a weakened humanity that gave rise to V. As the legends have it, the King was ultimately beaten and driven beneath the surface into the 24th Ward, where he is said to have raised a vast city and bided his time for the day ghouls might rise once more.

An expedition pushing into the lowest depths of the 24th Ward, led by Ayato Kirishima, stumbles upon what looks like a deserted city. Three of its inhabitants, ghoul children who insist they are human, claim their King, Nagaraji, laid the place to ruin in a shape resembling Kaneki's Dragon. Battling desperately for their lives, they broke apart the eyeball-like growths studding his kagune, blunting his assaults, until at last the King fell still and hardened into stone.

The King's kagune takes a serpentine shape, throwing out numerous arm-like appendages that stretch from one building to the next while taking on a stony quality. Its staggering scale suggests some transformation warped his kakuja into this gargantuan state, drawing comparison to the Dragon born of Kaneki's own kagune.
