<font>When she was still just a girl, Kotoko was kidnapped by <i>yokai</i> (spirits). They made her into a powerful intermediary between spirits and humans, but this power came with a price: one eye, and one leg. Now she''s falling in love with a young man named Kuro, who is also special: an incident with a <i>yokai</i> has given him healing powers. He''s surprised when Kotoko asks him to team up to handle renegade <i>yokai</i>, preserving the thin line between the human world and the spirit world. </font>
