Tsubasa RESERVoir CHRoNiCLE

A mysterious power within Sakura is awaken by the ruins as wings sprout from her back. Sakura beings to fade into the seal but Syaoran saves her. However, the wings break as the feathers scatter to many different worlds. Syaoran carries Sakura, now unconsciouses and her life fading away, out of the ruins to find themselves being attacked by mysterious mechanical warriors. Touya manages to keep them back as Yukito finds that Sakura's heart is no longer in this world. With no other choice, Touya leaves Sakura to Syaoran and Yukito sends the two to another world to seek help from the Dimensional Witch. Now in the world of XXXHolic, Syraoran is joined by Kurogane and Fai as he pleads to Yûko to save Sakura.

Transported to the world of XXXHolic, Syaoran, Kurogane, and Fai ask the Dimensional Witch Yûko to grant their wish. Syaoran's wish is to travel to many worlds to restore the memories of Sakura, Kurogane's wish is to return to his own world, and Fai's wish is to travel to different worlds to avoid his own. Though their intents are different, the method is the same and that is to travel between different worlds. However, they must all pay a price before their wishes can be granted. Kurogane's payment is his sword, Fai's payment is the marking on his back, and Syaoran's payment is his relationship with Sakura. Though hesitant about their payment, they pay up and are given Mokana Modoki to travel to the next world. After coming to, the gang find themselves in the middle of a gang war but instead of modern weapons, everyone is fighting with a special technique called a Kudan.

Sorata Arisugawa and Arashi Kishu find Syaoran, Fai, Kurogane, and Sakura (still unconscious but better) and take them to their apartment building. After some rest and less suspicious clothes, the three go around town looking for Sakura's memory fragments. However, Kurogane spots someone who looks like Princess Tomoyo and chases after her. After losing sight of the girl as well as Syaoran and Fai, Kurogane meets the gang from before and a fight ensues.

Sakura is awake and is checking out the town. However, she wakes up without Syaoran, Fai, Kurogane, and Mokana knowing it until it was too late. Things get worse when the leader of the invading gang recognizes her from his encounter with Syaoran and concocts a devious scheme.

Masayoshi and Mokona have been kidnapped by Primera as she leaves a challenge for Syaoran, Fai, and Kurogane. Though they run into some communication trouble since Mokona acts as a translator for them, they make it to Hanshin castle. Fai decides to fight in Syaoran's place as he reveals his Kudan which allows him to fight and a battle between Fai and Primera ensues.

Syaoran and Shogo begin their unfinished fight. As the fight continues in Syaoran's favor, Masayoshi and Primera are in danger as a result of their fight. However, Masayoshi's Kudan saves them but grows to a tremendous size as Mokana senses that Sakura's feather is in Masayoshi's Kudan.
