Tsubasa: Reservoir Chronicle (Japanese: ツバサ-RESERVoir CHRoNiCLE-, Hepburn: Tsubasa: Rezaboa Kuronikuru) is a Japanese manga series written and illustrated by the manga artist group Clamp. It takes place in the same fictional universe as many of Clamp's other manga series, most notably xxxHolic. The plot follows how Sakura, the princess of the Kingdom of Clow, loses all her memories and how Syaoran, a young archaeologist who is her childhood friend, goes on arduous adventures to save her, with two other companions. The Dimensional Witch Yūko Ichihara instructs him to go with two people, Kurogane and Fai D. Flowright. They search for Sakura's memories, which were scattered in various worlds in the form of angelic-like feathers, as retrieving them will help save her very being. Tsubasa was conceived when four Clamp artists wanted to create a manga series that connected all their previous works. They took the designs for the main protagonists from their earlier manga called Cardcaptor Sakura.

It was serialized in Kodansha's shōnen manga magazine Weekly Shōnen Magazine from May 2003 until October 2009, and was collected in twenty-eight tankōbon volumes, totalling 232 chapters - 18 to 20 pages each. The manga was adapted into an anime series, Tsubasa Chronicle (ツバサ･クロニクル, Tsubasa Kuronikuru), animated by Bee Train, which aired 52 episodes over two seasons during 2005 and 2006. Production I.G released an interlude film between the first two seasons titled Tsubasa Reservoir Chronicle the Movie: The Princess in the Birdcage Kingdom, as well as five original video animations (OVAs) between November 2007 and May 2009, which acted as a sequel to the second season. The manga was licensed for English language release by Del Rey Manga, who has released all of its volumes since April 27, 2004. Funimation licensed the anime for English release. They published all the TV episodes in DVD volumes as well as the film. The OVAs of Tsubasa were released in North America in January 2011. Various video games and drama CDs based on the series have been released. A sequel titled Tsubasa: WoRLD CHRoNiCLE started serialization in 2014 and ended in 2016.

The series has been well received by Japanese and English readers, and it reached high positions on various best-seller lists; the series has sold over twenty million manga volumes in Japan and one million units in North America. Both the manga and anime have had positive response from critics, who praised its connections to previous works and its artwork. The plot twists in later parts of the story have resulted in mixed reactions due to positive focus on the impact on the plot and negative one based on how confusing they are.

The series begins by introducing childhood friends with quite a strong and close friendship: Syaoran, a young archaeologist who is investigating a ruin within the Kingdom of Clow, and Sakura, princess of the Kingdom of Clow and daughter of the late king Clow Reed. When Sakura visits Syaoran in the ruins, her spirit takes on the form of a pair of ghostly feathered wings that disintegrate to other dimensions. As she descends into a catatonic near death state, Syaoran meets the Dimensional Witch, Yūko Ichihara, to whom he begs for help to save Sakura. Yūko is also visited by two others who each have their own wish: Kurogane, a ninja who wishes to return to his home world after being banished from his world by Princess Tomoyo to allow him to learn what true strength is; and Fai D. Flowright, a magician who wishes to never return to his home world, Celes to avoid his king, Ashura-ō. In exchange for the ability to travel across dimensions, Yūko demands that each pay with that they value most: Kurogane offers his sword Ginryū; Fai offers the tattoo that suppresses his enormous magical strength and power; and Syaoran offers all of Sakura's memories that involve him. Yūko then presents them with a creature named Mokona Modoki that sends the group on a journey across dimensions in search of Sakura's feathers. After obtaining the first feathers, Sakura awakens from her catatonic state and starts recovering her memories.^[4] During their adventures, the group gradually grows closer to the point that Fai jokingly labels them as relatives.^[5] As they travel, they learn that the feathers have their own unique abilities and can bestow several supernatural abilities to those who possess them.

During their journey in Tokyo, the group discovers that Syaoran is in reality a clone imbued with half the heart of the original Syaoran. Several years ago, Fei-Wang Reed, the wizard who caused Sakura to lose her memories, took the original Syaoran prisoner and created the clone to collect Sakura's feathers.^[6] Shortly after the original Syaoran breaks free of Fei-Wang's hold, the clone loses his heart and becomes an emotionless puppet that follows Fei-Wang's will, betraying the group. The original Syaoran joins in the group's journey with Sakura wishing to save the clone.^[7] Foreseeing a future in which Fai kills the original Syaoran forced by Fei-Wang's curse, Sakura gets stabbed in his place, but at the same time splits her body and soul, sending each to different worlds, Seresu and the Dream World, respectively. In the Dream World, the Syaoran clone destroys Sakura's soul when trying to get the feathers. Before her soul perishes, Sakura reveals that she too is a clone of the original Sakura who was also taken prisoner by Fei-Wang. Fei-Wang then takes Sakura's body to use its stored power. The group departs to rescue the two Sakuras learning from Yūko that Fei-Wang is in an alternate dimension from the Kingdom of Clow. Such parallel dimension is the result of Syaoran's wish to save the original Sakura from Fei-Wang's curse years ago. In order to grant his wish, Syaoran became Fei-Wang's prisoner and Yūko's assistant, Kimihiro Watanuki, was used to replace Syaoran within his original world's history.

The group battles Fei-Wang who destroys the Syaoran clone when he betrays him. He then uses the immeasurably strong ability and strength of the two Sakuras to resurrect Yūko, accidentally frozen in time by Clow Reed himself to halt her death, therein proving himself Clow's superior. Yūko uses her life and Clow's magic as payment to make the clones reborn in the past to live together. As the two know all of the series' events would repeat, the clones seal themselves in Yūko's shop until the battle against him. The group manages to kill Fei-Wang, who traps Syaoran in a void between time and space, dragging both his clone and Watanuki along as a consequence of their connection. With their creator's death, both clones of Sakura and Syaoran fade away leaving behind two feathers. Syaoran and Watanuki escape from the void for a price: Syaoran must continue traveling through the dimensions forever, while Watanuki must stay in Yūko's shop. The group rests in the Kingdom of Clow where Fai, Kurogane, and Mokona decide to join Syaoran once again in hope of finding a way to bring back the clones who still exist as the two feathers. Before departing on their separate ways, Syaoran and Sakura confess their mutually strong, close and pure romantic love for each other, as well as their shared real name, Tsubasa, as they hope to meet again.

Tsubasa: Reservoir Chronicle began with an inspiration of the four-member team, Clamp, to link their works set in a realistic world with their works set in different fantasy worlds.^[8] Prior to beginning work on Tsubasa: Reservoir Chronicle, Clamp had created the manga Cardcaptor Sakura, from which the two main characters are taken. Clamp decided to draw Tsubasa: Reservoir Chronicle by using a style first conceived by Osamu Tezuka, named the "father of manga" and often credited as the "father of anime", known as Osamu Tezuka's Star System. In this system, characters with the same name and design are used in different settings, drawing mostly from the vast character pool of its own works and occasionally from others' works. Unlike characters under the Star System, three months prior to the release of Tsubasa: Reservoir Chronicle, the Young Magazine began serializing Clamp's xxxHolic, a manga whose two main characters, Kimihiro Watanuki and Yūko Ichihara, are two of the same characters used in Tsubasa: Reservoir Chronicle; both series run in parallel. Like many of their other works, each member of Clamp had a role different from their other projects instead of retaining set roles. For Tsubasa: Reservoir Chronicle, Mokona drew the main characters, whereas Tsubaki Nekoi and Satsuki Igarashi drew the side characters and backgrounds; Nanase Ohkawa was the sole person in charge of the storyline; the other members of Clamp were not told in advance how the plot would unfold.^[9] The word "Tsubasa" was used so that the title would be easy to read. However, believing "Tsubasa" only would be too short, they added the words "Chronicle" and "Reservoir" from Nekoi's notes.^[10]

A special interview with Ohkawa and Kiichiro Sugawara, Clamp's editor from the Weekly Shōnen Magazine's Editorial Department, took place after the story of Tsubasa: Reservoir Chronicle had progressed past the arc from Ōto Country. Ohkawa has stated that the group is very conscious of the fact that Tsubasa: Reservoir Chronicle is the title in Shōnen Magazine with the youngest readership and that it is their very first foray into the shōnen demographic. Thus, the members of Clamp ensure that they employ a drawing style and dialogue appropriate for young male audiences;^[11] the manga incorporates furigana that makes reading Japanese easier. To aid in this effort, the group holds conferences with Sugawara where they discuss the plot. Ohkawa stated during the interview that the only time the story significantly changed was during Country of Jade arc; It went from a "horror story with vampires" to a "detective mystery".^[11] Following the story in the Piffle Country, Clamp aimed to make the series darker and more complex, resulting in it receiving elements previously seen in other of their series. The Shura Country's story was written to introduce the idea that a dead person cannot be revived even if somebody travels back to the past and changes history. This theme would be further explored later in the story.^[12]

The members of Clamp had some difficulty adjusting from their typical style after deciding to publish with Weekly Shōnen Magazine. Because their typical thinner lines did not give the desired impact, Ohkawa expressed the group's desire to make their lines thicker, and to use simpler layouts similar to the other stories already present in Shōnen Magazine. She stated that they used their original artistic style to attract initial readers and then slowly transitioned to a new style. Sometime around when the story arc focused on the Country of Ōto took place, their art style had gradually been changing again; at this point they were thinking of returning to their original style. They were still adjusting to a weekly schedule; many of their previous works were on a monthly schedule. Sugawara expressed concerns about the strain on the artists of concurrently doing a weekly issue of Tsubasa: Reservoir Chronicle linked with xxxHolic, but in the end he 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.^[11] The main idea was connecting these two series was to have protagonists from two different manga with different personalities and designs. However, during the ending they would be stated to share the same existence, and had to go on different paths.^[13] As Tsubasa is connected with xxxHolic, the characters' designs are also meant to be similar; Like xxxHolic, the artwork is sometimes influenced by Ukiyo-e art style which leads to the characters have longer limbs.^[8] When asked if another series influenced Tsubasa in the concept of parallel worlds, Ohkawa replied that she was not a fan of sci-fi series and pointed that all worlds shown in the series were other works from Tsubasa. At the same time, she wanted to segregate Tsubasa from previous works. She also explained that while some characters are the same, their traits and personalities were modified due to different backstories.^[14]

When thinking about including character goods with the volume releases, Sugawara came up with the atypical idea of releasing a deluxe and normal edition of the manga after contemplating the inconsistency of novels getting both a soft-cover and hard-cover release, but manga only received one version. Because it was a new concept, the group experienced several mishaps such as accidentally placing a vertically flipped illustration on the first deluxe edition. The group also decided to use another atypical practice of keeping catchphrases that appeared in the magazine identical to the ones that appear on the frontispieces of the deluxe editions.^[11]

Tsubasa explores the fragility of human relationships through Sakura losing all of her memories involving her love interest, Syaoran.^[15] Despite this tragedy, Syaoran manages to become friends with other characters across his journey. Furthermore, Sakura once again develops feelings for Syaoran who at the same time starts falling for her again. The development of the characters' relationship demonstrates how while modern society depends on already existing one, a severed one can be reformed if people have the will.^[15] At the same time, Syaoran has to say goodbye to the people he met as a result of having to continue travelling. Despite also losing these newfound friends, these actions will help Syaoran grow into a young man.^[16] Based on the shōjo manga character Syaoran Li, the initial Syaoran from the series was written to be a shōnen manga lead instead.^[17] As a result, the narrative places emphasis on his friendships as he obtains new powers while retaining a kind demeanor.^[18] Although the series is a shōnen manga, Clamp incorporates shōjo manga motfifs into the character to attract a female demographic, with his desire to recover the magic feathers of Sakura being a common element of shōjo manga. The angel-like feathers and multiple outfits serve as a mean to appeal to the female demographic while the ending exploring the characters named Tsubasa serve as major symbolism about romantic relationships.^[19]

Another theme in the series is the use of identical people as a result of the characters travelling to parallel worlds where they find alternative versions of people they met before. Despite sharing the same physical appearances, these identical versions have been through different experiences earning their own identities.^[20] Syaoran also has his own doppelgänger commonly referred as "The Other Syaoran" who at the same time shares the same identity as the protagonist from xxxHolic, Kimihiro Watanuki. Across the series, these character are developed and choose their own paths to earn their own identities.^[13] The exploration of cloning in Tsubasa becomes a major theme in the narrative despite Syaoran and Sakura being identical to their original personas, they have different identities that the audience is given as a reward to explore.^[21]

Tsubasa: Reservoir Chronicle was fairly well received by reviewers, who described it as a treat for Clamp fans due to the large number of crossover characters in the series.^[118] Initial fan response to Tsubasa: Reservoir Chronicle was that it was "Cardcaptor Sakura for guys". Fans speculated that the series would conclude one of Clamp's unfinished series, X, or that it would be a sequel to Cardcaptor Sakura that focused on the character Syaoran Li.^[119][120] Critics described the series as being marked by several plot twists, with About.com writer Katherine Luther labelling it as "perhaps the "twistiest" of twists that we have seen in anime and manga in quite some time".^[3] For the earlier half of the series, Mikhail Koulikov from Anime News Network described the series as settling into a "predictable pattern" that Melissa Harper, also from Anime News Network, described as somewhat slow, and "frankly a bit boring".^[121][122] However, Michael Aronson from Manga Life found the series appealing and accessible to readers who have not read other Clamp series, and he hoped it would remain this accessible for following volumes. He found that the relation between Tsubasa: Reservoir Chronicle and xxxHolic would persuade readers to also read the latter series.^[123] Mania Entertainment's Megan Lavey found the introduction to be a "pretty simple love story", while liking the characters' personalities. She liked how the series was connected with xxxHolic and hoped that both series would continue crossing over.^[124] In a general overview of the manga, Julie Gray from Comic Book Bin gave positive remarks to the characters' complex personalities and how the plot has been developed throughout its first ten volumes. She recommended that people should buy the series.^[125] Active Anime's Blake Waymire found that the change of settings was well done, and he noted how some story arcs could go from dramatic to charming.^[126]

From volume 15 onwards, Clamp unleashed a series of "mind-blowing" plot twists that had been foreshadowed frequently throughout the series. These twists have been described by Anime News Network as "stunning" but confusingly executed due to the sheer number of storylines coming together.^{[127][128][129]} Other critics praised the pacing as letting "the story progress at its own natural momentum", keeping the reader "from being bored by any one literary genre".^[130] The plot twists and the ever-changing relationships between the manga's main characters were praised; "few manga creators could pull off this sort of outrageous storytelling stunt".^[131] Active Anime writer Holly Ellingwood called the plot twists as "the most shocking set of events in the Tsubasa Reservoir Chronicles to date!", finding that despite such twists, more secrets were brought to readers to persuade them to read the following volumes.^[132] Ellingwood also reviewed following volumes and found the last plot revelations intriguing; she enjoyed that a strong connection is revealed between characters from Tsubasa and xxxHolic.^{[133][134][135]} Comic Book Resources regarded the ending of the series as bittersweet homage to Cardcaptor Sakura due to the clones disappearing and the original Syaoran separating from Sakura despite confessing their mutual love.^[136] Manga News praised the ending for the heavy focus on the clones of Syaoran and Sakura, giving emotional scenes as well and their relationship Yuko and Fei-Wang Reed but lamented Fai and Kurogane had less prominent roles.^[137]

Critics have described the artwork as "keeping up the standards expected of Clamp" with its high level of detail, though perhaps too much detail, especially during action sequences.^[122] The artstyle is "stylish" and "dynamic", characterized by a large number of "sweeping lines curlicues that look unlike anything else in the genre" that help bring the action scenes to life for exciting experiences.^{[128][129][130]} Ed Sizemore from Comics Worth Reading highlighted the fact that each dimension that the protagonists visit is characterized by its very own look and feel so that "no two worlds are even remotely similar".^[130] However, the amount of detail and lack of contrast, while beautiful, often render scenes incomprehensible to the point where the reader is left guessing who is attacking.^[128][138] Critics have praised Del Rey's inclusion of English translation notes that aid in understanding the plot, especially due to its crossover nature.^[122] Lavey found the translation a "good read", liking how some Japanese words were not translated and instead explained in notes.^[124] The handling of fight scenes, most notably Syaoran's, was highly praised.^{[139][140][141]} Paul Price lists both Tsubasa series as examples of isekai in "A Survey of the Story Elements of Isekai Manga" for the Journal of Anime and Manga Studies, describing them as "immersive", examples of isekai where there is no portal between worlds and all the action takes place in fantastical other worlds rather than the real world.^[2]

Critics have described the anime adaptation as having a very slow pace but having a beautiful musical score. Carl Kimlinger from Anime News Network faulted the director, Koichi Mashimo, for "downshifting the plot's energy" and as having "too many flashbacks, too many slow pans over inexpressive eyes", that create an end-product that is "tediously formulaic".^[142][143] Active Anime's Christopher Seaman had mixed feelings, finding the romantic themes mature and the magical themes appealing to younger audiences; he concluded that "teens would get the most out of the series." He recommended the series in general, praising its plot and its themes.^[144] DVDTalk's Todd Douglass Jr. ranked the anime DVD box as "Highly Recommended"; he liked how, despite borrowing elements from other series, it was "entirely self-contained".^[145] Douglas pointed out that following its second season, the anime kept entertaining viewers, and felt they would not find a reason to dislike it.^[146] Douglas enjoyed the anime's storytelling. He liked its characters, but found it sometimes dragging due to its episodic nature.^[145] Kimlinger praised the musical score as being beautiful, as Yuki Kajiura's work has always been.^[147] Chris Beveridge from Mania Entertainment made similar comments, praising the series' score and animation, while commenting on the series' accessibility. He said that people unrelated with Clamp's works would like Tsubasa, in contrast to other people who would "get out of the series".^[148] Its episodic nature was praised by Luther, who commented how the main plot was connected to each of the story arcs.^[3] The English cast for the anime has been labelled as "done and very solid". IGN's Jeffrey Harris felt Christopher Sabat was its best actor. Harris called the anime "a nice looking and at times elegant looking show",^[4] pointing to the traits of the main characters. He criticized the lack of extras in the DVDs releases.^[4][149] Reviewing the anime's and xxxHolic's films, IGN writer N.S. Davidson said the Tsubasa film would be appealing to viewers of the series, despite its short length. He liked how both films' storylines interacted, allowing parts of the plot of Tsubasa to be explained in the xxxHolic film, and he found artistic similarities between the two films.^[150] Carlo Santos was more critical of the film but still called it "good art".^[151] In a TV Asahi poll, Tsubasa: Reservoir Chronicle was ranked as the fifty-ninth most popular anime in Japan.^[152] It ranked ninth in Animage's Anime Grand Prix anime popularity poll from 2005,^[153] while it was also listed as an "Honorable Mention" in IGN's "Top Ten Anime of 2007" feature.^[154]

Although the Tsubasa OVAs were not the first original animation DVDs (OADs), OVAs published with manga volumes, its release helped to popularize the term.^[62] Chris Beveridge from Mania Entertainment considered the OVAs to have better quality than the TV series, mainly because they were developed by Production I.G instead of Bee Train and because they have a darker storyline.^[155][156] In a further review, Beveridge found fascinating the events occurring in the OVAs due to the number of revelations changed the way people viewed the series. The character designs were felt to be more similar to the manga's ones than the TV series,^[157] while the animation has been considered "a notch above that of standard Television". The themes were noted to be more mature both brutally and mentally; although the number of changes presented throughout them has been praised, another series of OVAs that would conclude the storyline built in the last episode from Spring Thunder Chronicles has been requested by reviewers.^[157][158]
