xxxHolic (stylized as ×××HOLiC; pronounced "Holic") is a Japanese manga series written and illustrated by the manga group Clamp. The series, which crosses over with another Clamp work, Tsubasa: Reservoir Chronicle, revolves around Kimihiro Watanuki, a high school student who is disturbed by his ability to see the supernatural, and Yūko Ichihara, a powerful witch who owns a wish-granting shop. When Watanuki asks Ichihara 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 to link the supernatural and fantasy series. From 2013 to 2016 they worked on a sequel series xxxHolic: Rei.
xxxHolic was serialized in Kodansha's seinen manga magazine Weekly Young Magazine periodically from 2003 until March 2010. It then moved to the shōnen manga magazine Bessatsu Shōnen Magazine in June 2010, where it ended serialization in February 2011. The manga is published in tankōbon volumes under the KC Deluxe label; a total of nineteen volumes have been released. It was first published in the United States by Del Rey Manga and in the United Kingdom by Tanoshimi in 2004, then was later published in a series of omnibuses by Kodansha Comics as of 2014. In 2005, Production I.G adapted the manga into an animated film, which was followed by two anime television series, and various original video animations (OVAs). Funimation licensed the film and the first TV series in North America, and released both of them in DVD as well as Blu-ray Disc. A light novel and a video game have also been released based on the series.
The manga has been well received by both Japanese and English readers and has appeared in various rankings of bestselling books. Critics have generally praised the series for its illustrations and its portrayal of supernatural elements.
Kimihiro Watanuki is a high school student plagued by ayakashi spirits which are invisible to everyone else but him. The series begins when Watanuki stumbles, seemingly by chance, into a shop that grants wishes. 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; so, as payment, he must become Yūko's temporary, part-time cook and housekeeper. While his established job consists of household chores, Yūko increasingly sends him on errands of a supernatural or spiritual nature as the series develops. Himawari Kunogi, Watanuki's love interest, and Shizuka Dōmeki, a classmate whom Watanuki initially detests, occasionally join him in his work as per Yūko's request. The three become increasingly close, and though Watanuki is often annoyed with Dōmeki, he grows to value the new friendships he makes and his life at the wish shop. At the same time, though, he begins to worry about Yūko, wondering if she who grants wishes to others ever has anything to wish for herself. Eventually, he makes a promise to try and grant her a wish, should she have one.
With each supernatural encounter, Watanuki becomes more familiar with and connected to the spiritual world. A crossing plotline with the concurrent series Tsubasa: Reservoir Chronicle reveals that Yūko is actually on the verge of death, and she is only alive now because her personal time was accidentally frozen long ago by the powerful wizard Clow Reed. As the magic binding her in time begins to dissolve, Yūko's ability to maintain the shop's magical existence fades, and she eventually passes on, telling Watanuki that he will finally be free of his ability to see demons. However, Watanuki chooses to retain his ability to see spirits in order to maintain Yūko's shop and take over her role of shopkeeper. Further cross-over plotlines reveal that Watanuki was born as a result of a wish to turn back time by a shop client, Syaoran of Tsubasa. Since Syaoran was able to go back in time (at the cost of being removed from his timeline and becoming imprisoned by the sorcerer Fei-Wang Reed), Watanuki was born to replace the void in timespace Syaoran left behind, and thus while they are different people, they share an "existence". As the series reaches its conclusion, Syaoran and Watanuki become trapped in a void by Fei-Wang and must pay a price to become free and continue existing. While Syaoran decides to keep traveling through dimensions, never stopping in a single place, Watanuki chooses to stay inside the shop and act as its owner, granting wishes until the day he sees Yūko again. As time progresses, Watanuki continues working in the shop without aging. Dōmeki, his assistant, frequently visits him, and the tradition continues with Dōmeki's descendants. After 100 years pass, Watanuki has a dream of Yūko, who tells him that he has finally become powerful enough to leave the shop. Despite this, he decides to continue waiting inside the shop for the day that they meet again.
xxxHolic was conceived when the group Clamp wanted to link the supernatural and fantasy series they made with a realistic one. This idea was further worked with the creation of the character of Yūko Ichihara who would bridge the stories from xxxHolic and Tsubasa: Reservoir Chronicle. Clamp proposed the idea of writing xxxHolic to Young Magazine after Chobits. In the end they decided to publish both xxxHolic and Tsubasa in weekly magazines to make serialization easier. The manga's title was originally going to be "addicted" but it was changed for the less ambiguous "holic." Like Clamp's previous work Tokyo Babylon, xxxHolic focuses on social pathologies but with a more esoteric tone. The "xxx" before the holic is the Japanese way of saying of "fill in the blank." Therefore, the title itself gives a hint about what the series are about. It is talking about the people with the problems such as an alcoholic, or a workaholic. Being a fantastical series, these "---holics " can have very different pathologies.
The art style of the manga draws on the influence of ukiyo-e wood prints. When making a chapter composed of about twenty pages, Clamp takes around two days to make the artwork, the time differing with the ones from other series they made. The script of the series made by Nanase Ohkawa, who the other Clamp members ask her about any confusion they have before starting drawing the chapters. The illustrations and character designs are mainly done by Tsubaki Nekoi with assistance from Mokona, although Satsuki Igarashi also draws various parts. For the series, they decided to use Japanese and Chinese themes, but avoided using tones. Mokona is mainly in charge of designing the female characters, while Nekoi draws the male ones and all the spirits featured. The artwork is also inspired by Alphonse Mucha who Mokona is a fan of. This leads to all the tankobon covers being gold or silver and then color printed over it. The series was retitled xxxHolic Rō ever since volume 16 because of how Watanuki replaced Yuko as the shop's owner.
When first presenting the idea of running xxxHolic linked with Tsubasa: Reservoir Chronicle, although Ohkawa expressed concerns for the strain the weekly pace of such a series would place on the artists, she whole-heartedly approved. In accordance with Ohkawa's desire for each to have a well-organized story, Clamp avoids putting references between the two stories too frequently. The reasons for linking these two series was because Clamp wanted to have two protagonists from two different manga with different personalities and design, yet during the ending they would be stated to be same person, and had to go on different paths. Because Tsubasa: Reservoir Chronicle was more focused on action scenes, Clamp sometimes took breaks from xxxHolic or create autoconclusive stories so that the storyline between the two series would always be linked. In April 2010, Clamp stated that the xxxHolic was taking longer than what they expected, causing delays to some of their other works. When the manga finished serialization, Clamp felt it was more the ending from xxxHolic Rō, pointing that xxxHolic had already ended. Regarding the series' finale, Clamp wanted to express that while Watanuki's decision to stay in the shop may seem sad for readers, for Watanuki it was his happiness. Clamp was satisfied with people's reaction to the last chapter, as when discussing Watanuki's fate, they were also thinking what is happiness for them.
As the title implies, the manga focuses on addictions to regular habits. These addictions are expanded in a supernatural setting serving as a parallel to real world societies. Watanuki's problem of being constantly followed by demons can be compared with the sensation of a normal person feeling scared by the belief he is observed. Across the series, several clients with different addictions visits Yuko's shop seeking help. Solving these cases results in moral dilemmas. Clamp places emphasis on the importance of words when writing the manga. Yuko's dialogues always affect the other characters due to how direct and secure she is when speaking. In early chapters, while she worries a woman addicted to the internet by labeling her husband and child as "other people," Yuko is transmitting the philosophy of individualism and the power her client has. In contrast to Yuko, another client has a tendency to lie which brings her misfortunes.
Written and illustrated by Clamp, xxxHolic has been serialized in Kodansha's journal Weekly Young Magazine periodically from 2003 until March 2010 before moving to Bessatsu Shōnen Magazine in June 2010. A one-shot chapter of xxxHolic was also published in Weekly Shōnen Magazine in its June 2010 issue featuring a crossover with Tsubasa: Reservoir Chronicle. It ended serialization on February 9, 2011 in the Bessatsu Shōnen Magazine. The 213 chapters are collected and released in tankōbon format by Kodansha. The numbers of chapters for such release was reduced by combining the ones from the original serialization. Starting volume 16, the series is retitled xxxHolic Rō (×××HOLiC ◆ 籠, lit. "xxxHolic Cage"), but the number of chapters follow the previous ones. The first volume was released on July 25, 2003, and the last volume, the nineteenth, was published on March 9, 2011.
xxxHolic was one of the first four manga series licensed for English release in North America by Del Rey Manga, and was acquired together with Mobile Suit Gundam SEED, Negima!: Magister Negi Magi, and Tsubasa: Reservoir Chronicle in January 2004. Del Rey published its first volume on April 27, 2004, and on February 21, 2012, the nineteenth and final volume was released. Kodansha USA re-released it in 3-in-1 omnibus format in 2014. The series has also been licensed for an English-language release by Tanoshimi, who released the first nine volumes in the United Kingdom with the first one on August 3, 2006.
A new xxxHolic manga titled XXXHOLiC Rei (XXXHOLiC ◆ 戻 < レイ >, lit. "xxxHolic Return") was announced at The CLAMP Festival 2012 event. It was scheduled to be published in Kodansha's Young Magazine in February 2013, however a month's delay in the magazine's issue release dates changed this to March 2013. Kodansha USA announced in July 2013 they licensed the manga for English release, releasing the first volume in 2014.
Production I.G produced an animated film of the series titled xxxHolic: A Midsummer Night's Dream (×××HOLiC: 真夏ノ夜ノ夢 - xxxHOLiC: Manatsu no Yoru no Yume) which premiered on August 20, 2005 alongside Tsubasa Reservoir Chronicle the Movie: The Princess in 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.
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 & Gromit: The Curse of the Were-Rabbit, and the award winner, Renaissance.

In Mania Entertainment's "Best Manga Awards For 2005", xxxHolic was the winner in the category "Best Mature".
The xxxHolic manga series has also been well received by various publications with Mania Entertainment's Megan Lavey praising its focus on the people's thoughts, as well as its comedy. She also found its connection with Tsubasa: Reservoir Chronicle appealing due to events being depicted from different points of view, persuading readers to read both series. Michael Aronson from Manga Life stated the series' introduction had potential to be worth reading due to its episodic nature and found some of its characters to be "gripping", though Dan Polley, also from Manga Life, commenting that Watanuki "does seem a little bit weak to be the lead character". On the other hand, Matthew Alexander from Mania Entertainment stated that Watanuki's character was well developed across the series, becoming more appealing. Joy Kim, another writer from Manga Life, praised how despite its episodic nature, the narrative brought by Watanuki's interactions with other characters made every panel "loaded with significance". Carlo Santos of Anime News Network liked how later volumes of the series "[outdid] itself by breaking into the world of dreams", compared to initial volumes that focused on the interaction between humans and spirit. Active Anime found its emotional tension as well as its connection with Tsubasa some of the main reason why the series is worth reading. Not having read Tsubasa, Matthew Alexander felt that the addition of elements from the series into xxxHolic was well-made, as it started to suggest a connection between the two series' protagonists. However, Santos found the series' connection with Tsubasa to be confusing to the point that only readers from both series would understand some explanations.
Regarding events happening from volume 15 onwards, Active Anime's Holly Ellingwood called them "tragic, inspiring, and beautifully, breathtakingly sad", enjoying the way Yuko's fate was revealed, but wondering how it would continue. Carlo Santos stated that although the series lost its "star performer", it kept being appealing due to the fact that Watanuki replaced her and found most of volume 16 as "an exercise in getting back on one's feet after a heartbreaking loss, and it is all the more inspirational for that." Matthew Alexander from Mania was more critical to these events due to the how it became "an ultra serious downer" due to Yuko's loss and the lack of its recurring comedy. Additionally, he cited the events regarding Yuko's disappearance and later death were not explained in xxxHolic, stating that only readers from Tsubasa would understand such events. The artwork has been praised because of its "striking designs and patterns built into the images", various notable traits from Clamp, as well as for being "equally memorable and evocative". On the other hand, it has also been criticized for being "less visually busy than Tsubasa" due to some pages lacking backgrounds, though critic Michael Aronson for Manga Life stated that the panels' composition is able to make up for such issues. Rebecca Silverman review the opening volume of xxxHolic: Rei gave the sequel a B+ rating, praising the way the story now flowed and the artwork, but said that the story was, "a little too mysterious in places".
The anime adaptation of xxxHolic has received mixed reception from different publications, with Anime News Network's Casey Brienza liking how its first season is faithful to the original material. However, she found that some of Funimation's subtitles in its first episodes to be confusing, advising people to watch the English dubbed version instead. In a bigger overview of the first season, Carlo Santos found issues with the animation's unintentional "super deformed" moments in which the characters' limbs became notably longer. He also criticized some of its episodes' storytelling as it "falls flat" due to trivial issues discussed. Holly Ellingwood from Active Anime called the series "one of the most distinctly imaginative" because of the combination of supernatural elements and comedy. Pointing to the animation quality, Ellingwood found each character distinctive and the animation issues to be comical. DVD Talk's Todd Douglass Jr. gave praise to the themes touched upon in the anime series. Despite giving disapproval to its episodic nature, Douglass found the characters appealing due to their development over the series. IGN writer Jeff Harris found its start "tolerable", stating that fans from action series may not be interested by xxxHolic despite its potential. Like Santos, he commented on its animation, citing similar issues with the design, noting some moments lacked the fluidity seen in other parts of the series. He also criticized the blank background choices, questioning if they were truly artistic decisions or done to save on animation costs. Chris Beveridge of Mania gave a mixed review for the animation, agreeing with Santos and Harris, but still enjoyed the animation style, concluding that "everything about the visual design of the show is very appealing." Analyzing its episodic nature, Beveridge enjoyed the format, and praised the series' ability to strike a balance between light and dark parts of its stories.
