It is the Heian era (794-1185); Yorimichi is a young onmyouji, the son of a famous onmyouji leader of the imperial court. As a boy, he had been hailed for his incredible talent - but a certain incident during childhood stripped him of all his memories and the ability to 'see'. Lord Koretaka, once the crown prince renowned for his brilliant mind and steadfast personality, is now in exile - supposedly as punishment for murder. Upon their first meeting, Yorimichi's powers are instantly re-awakened. Intrigued by what he believes to be Koretaka's amazing abilities, Yorimichi decides to swear allegiance to the prince.Note: Mag Garden's Comic Blade Avarus is a shoujo magazine.
