Urotsukidoji: Legend of the Overfiend

Synopsis

According to an ancient legend, humanity is not the only civilization that holds dominion over the Earth. Two other races exist alongside them: the Makai, a demon race, and the Juujinkai, beings who are half-human and half-beast. Once every 3,000 years, a supreme entity called the Choujin—also known as the Overfiend—is destined to appear and restore balance to all three realms of the world. In modern-day Japan, after three centuries of relentless searching, a Jujinkai named Amano Jyaku finally detects the Choujin's presence within Tatsuo Nagumo, a slacker attending high school. Now Amano, together with his sister Megumi and their companion Kuroko, must protect Nagumo and his new girlfriend Akemi Ito from the Makai, who are convinced that Nagumo is not the Choujin at all, but a malevolent force determined to annihilate every living being on Earth.
