×××Holic (Japanese: ×××ホリック, Hepburn: Horikku?), pronounced as "holic," is a seinen manga written and illustrated by the group of manga artists known as Clamp. The series, which crosses over with another Clamp work, Tsubasa: Reservoir Chronicle, revolves around Kimihiro Watanuki, a high-school student disturbed by his ability to see the supernatural, and Yūko Ichihara, a witch who owns a wish-granting shop. When Watanuki asks Yūko to remove his ability to see spirits, she grants it on the condition that he pay for his wish by working for her. Clamp created xxxHolic because they wanted a series that would link to their other works. They are currently working on a spin-off series xxxHolic: Rei.xxxHolic was serialized in Kodansha's Young Magazine periodically from 2003 until March 2010. It then moved to Bessatsu Shōnen Magazine in June 2010, where it ended serialization in February 2011.
