Ai Eishi Manga

The protagonist is a mysterious and resourceful man who goes by the name "Zero." An expert on artworks, antiques and ancient artefacts, Zero is adept at rooting out their histories and uncovering any unusual qualities they possess. Because of this, he frequently gets called on to dispel "curses" and to both uncover and create forgeries. Zero is a man who will stop at nothing to see a job done, but he will also charge whatever fee he deems appropriate: it might be a billion dollars, or it might just be one.
