Akatoki no Yami

During the Heian era, Kamo Yorimichi is the son of a prominent onmyouji court official and was once celebrated for his exceptional abilities. A childhood incident caused him to lose his memories and the capacity to 'see' spiritual phenomena. Koretaka Shinnou, formerly a prince known for his intelligence and strong character, is now exiled, supposedly for committing murder. When Yorimichi meets Koretaka, his lost powers return immediately. Yorimichi becomes fascinated by what he perceives as the prince's extraordinary talents and chooses to pledge his loyalty to him.
