In Taoism Zhong Kui was a man who desired to be the Emperor's personal physician. He was said to be unpleasant to look at and had a disfigured face. Despite exceling in the Imperial Exams, the Emperor of China refused to grant Zhong Kui the position of physician because of his appearance. Distraught, Zhong Kui committed suicide by bashing his head repeatedly at the imperial gates.
One night when the Emperor was gravely ill, he had a dream in where he saw two Mo Guai (demons). The bigger demon, who was wearing an official's hat, ripped out the smaller demon's eye and ate it. The bigger demon then introduced himself as Zhong Kui. He said that he had sworn to rid the empire of evil. When the Emperor awoke, he was cured of his illness. His worship eventually spread to Japan.
Zhong Kui is a member of the Divine Powers who guards the Stone Passages found beneath Tsukiji Konganji. Though he knows they're are kids, he makes it clear that neither side should hold back. During battle he will even try to spar with Nanashi, who can best him if his level is higher than Zhong Kui's. Upon defeat he realizes he underestimated them, but is happy at the result even as he dies. Unlike most members of the Powers, Zhong Kui truly does think he is fighting for a righteous cause and holds a honorable attitude, showing his respect and taking his defeat with dignity.
"Zhong Kui of Chinese lore, he is a god that can command ghosts and spirits. One day, when the Emperor Xuanzong was sick, he had a dream where a ghost appeared and tormented him, but Zhong Kui destroyed it. After waking up from the dream, the emperor was cured of his illness. As a human, he committed suicide after failing an exam to become an imperial official, but Emperor Gaozu gave him an honorable burial. To repay the emperor, Zhong Kui swore to rid the world of demons."
