Tsubasa RESERVoir CHRoNiCLE - Season 1 Episode 2 : The Power to Fight 2006

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.
