Trivia: Tsubasa Reservoir Chronicle

  • Actor Allusion: Syaoran's voice actors; Miyu Irino happened to start travelling across dimensions in Kingdom Hearts as a young brownhaired kid. Jason Liebrecht also voiced a kindhearted hand to hand fighter from Street Fighter IV suffering amnesia who was related with a dude who had a huge chin.
  • Awesome, Dear Boy: The Spanish dub director watched Manga/X1999 and studied the work of its seiyu to make the Sakura dub more faithful in the common characters.
  • Creator Backlash: CLAMP was very dissatisfied on how the anime turned out due to Executive Meddling. This results to having Production I.G adapting the Tokyo Arc instead, disregarding all the filler episodes from the anime.
  • Executive Meddling: NHK produced the series to be on par of their adaption of Card Captor Sakura resulting in a more lighter adaption and rejecting any more of the violent moments. Bee Train was given sixth months to animate.
  • Fan Nickname: Quite a few.
    • The names Fai gave everyone in Outo became quite popular among the fans: "Big Doggy" for Kurogane, "Little Doggy" for Syaoran, "Big Kitty" for Fai, and "Little Kitty" for Sakura.
    • Fai-mommy and Kuro-daddy are also canon nicknames that have taken on a second life in fandom.
    • Ass-Chin for Fei Wong
    • "Cloney" for Syaoran's heartless clone, sometimes called C!Syaoran in contrast to R!Syaoran.
    • Junior or Syaoran-jr when Real!Syaoran turned out not to be a real at all, but Sakura and Syaoran Li's son taking his father's name.
    • Tsubasa-kun and Tsubasa-chan
  • Hey, It's That Voice!: Maaya Sakamoto, who voices Tomoyo, also voiced the Sealed Card(The Nothing/ The Hope) from Cardcaptor Sakura's second movie. She also sang Cardcaptor Sakura's third opening theme song "Platinum".
  • I Knew It - Some of the fans actually guessed the My Own Grampa thing more than two months before chapter 223 was published. Wow.
    • And some knew the names of the real Syaoran and Sakura a long time ago, too, although most if not all of the people who Knew It only knew one or the other
    • At least one person guessed that Yuuko was dead long before it was actually revealed.
    • Jossed: A lot of fans were convinced that Fai was going to die before the series ended. He didn't.
  • Names to Know in Anime: You have the manga team CLAMP of course.
  • The Other Darrin:
    • Kusanagi and Tomoyo got their dub VAs replaced in the OVAs.
    • Fei Wang Reed was first voiced by Randy Tallman in the dub but had to be replaced with R. Bruce Elliot for the second season, following Tallman's death.
    • The Spanish dubs of the movie and the anime were done by different casts due to a true war of dubbing companies. It started when distributor company Jonu Media chose to dub the Cardcaptor Sakura movie with their own VAs instead of the ones which had dubbed the anime, employed by distributor Arait Multimedia. In response, when Jonu dubbed the Princess of the Birdcage Kingdom movie, Arait refused to use Jonu's voice actors to dub Tsubasa and used instead their own actors, which also was most of the original cast from Sakura. The connection between the voices and the characters was well received by many fans, but the increasingly heated relations with Jonu pretty much made impossible the OVAs to be dubbed.
  • Talking to Himself: Tokyo!Subaru and Tokyo!Kamui are both voiced by Micah Solusod in the English dub.
  • What Could Have Been:
    • CLAMP originally made the storyboard for the second season opening. But it got rejected by Bee Train in place for the current second opening which is a slide show.
    • The anime could have a third season. But due to NHK's Executive Meddling to make a show lighter and kid-friendlier as opposed to being close to the manga which is heading toward Darker and Edgier, CLAMP became disappointed with the results and had Production I.G continue the anime in a form of the OVAs.
