The manga has become one of Shueisha's bestsellers, with over 25 million copies sold. In Japan and North America, several individual volumes have appeared in weekly top-ten lists of bestselling manga. Although most reviewers found it similar to other "shōnen" manga, they compared its moments of originality and well-developed characters favorably to other series of the same demographic. Hoshino's artwork has received mostly positive reviews; most critics have commented that her characters are visually appealing and that the Gothic elements in her art are pleasant to look at. However, one critic of her artwork has said that Hoshino's fight sequences can be difficult to follow.
