XxxHolic

×××Holic (×××ホリック), pronounced "holic" is a manga by Clamp which has also received a TV anime adaption. The storyline of xxxHolic crosses over with that of a number of other Clamp series, the most notable of which are Tsubasa: Reservoir Chronicle which was written in tandem with it, and Cardcaptor Sakura, whose history it draws on at several points.

xxxHolic has been serialized in Kodansha's Young Magazine periodically from 2003 until March 2010 before moving to Bessatsu Shōnen Magazine in June 2010. The manga is published in volumes under the KC Deluxe label. It is currently published in the United States by Del Rey Manga and in the United Kingdom by Tanoshimi. The art style of the manga draws on the influence of ukiyo-e wood prints.

Plot
Kimihiro Watanuki is a high school student plagued by yōkai and ayakashi, spirits with a strong attraction to him. The spirits are invisible to others and encounters with them are extremely troublesome. When he stumbles into a shop that grants wishes, however, events in his life promise to become more unusual. The shop is owned by Yūko Ichihara, a mysterious witch of many names and esoteric renown. For a price, she offers to grant Watanuki's wish to be rid of the spirits. The price, according to Yūko, must be of equal value and so, as payment, he temporarily becomes Yūko's part-time employee. Watanuki's job consists of small errands dealing with the supernatural and household chores. His love interest, Himawari Kunogi, and "rival", Shizuka Dōmeki, occasionally join him in his work as per Yūko's request. The three become increasingly close despite Watanuki's annoyance with Dōmeki.

During the climax of Tsubasa: Reservoir Chronicle, Yūko sacrifices her life to help Syaoran and Sakura achieve their goals. Watanuki decides to become the shop owner and waits for the day he can grant Yūko's wish.

Both the film and the anime series are directed by Tsutomu Mizushima. Ageha Ohkawa, Clamp's director and main scriptwriter, is executive producer of the TV series.

Film
xxxHolic: A Midsummer Night's Dream (劇場版 xxxHOLiC 真夏ノ夜ノ夢) premiered on August 20, 2005 alongside Tsubasa Chronicle the Movie: The Princess of the Birdcage Kingdom. The DVD version was released on November 24, 2006.

In the film, Yūko receives a request from a woman to help her back into her mansion, which does not allow her to enter. Yūko says that since Watanuki was the one who brought the client to her, he should be the one to grant her wish and therefore is brought along with her and Dōmeki. Yūko also attends because she has been invited to the mansion with many other famous collectors by the same letter, with the mansion filled with strange rooms and mysterious letters telling its guests what to do in place of a host. Though the collectors come to the theory of a mysterious auction being held, as in some urban legends, it becomes apparent that something more sinister and mysterious is going on as the collectors begin to disappear and a number of other strange occurrences happen.

The film was selected as a finalist for the Annecy International Animated Film Festival 2006 in the Feature Films category with other four nominees: Asterix and the Vikings, Origin: Spirits of the Past, Wallace and Gromit, and the award winner, Renaissance.

Reception
In 2008, the Japanese copy of manga volume thirteen of xxxHolic claimed 43rd in the top 50 manga sold in Japan with 451,942 copies sold. Volume 13 also hit #6 on the New York Times list of bestselling manga shortly after its launch in April 2009.

Carlo Santos of Anime News Network finds that the series "has often been about the interaction between humans and the spirit world, but this time the series outdoes itself by breaking into the world of dreams". He also added that, "no matter where the story heads next, some things remain constant: the unique artwork, the reflective mood, and Yûko's ruminations on life and what lies beyond ... all of which add up to one of the shining examples of the supernatural genre."
