The Emperor's Shaman

Shuka is an apprentice to her master as a shaman—a specialist in spells in everything supernatural. Since birth, she's been despised as a "monster" because of her white hair and red eyes. So, it's to her surprise when she receives a request from the handsome emperor Hakuen! But there's a catch—to fulfil his request, she must join the inner court as a fake consort!
