Peach-Pit is the name of two mangaku, Banri Sendou and Shibuko Ebara.  This is a departure from their usual style, and shows that they can write with dash and produce drawings in a style with plenty of movement and a certain dark style.  Fans of Buffy and similar tales will enjoy this story of supernatural bargains, which certainly left me wondering what was going to happen next.  It is a story that kept me guessing, turning the pages late into the night to find out how it ends... but in true manga style, this is just the first book in the series.  Different and exciting, with some particularly impressive illustrations.
