ツバサ－RESERVoir CHRoNiCLE － Tsubasa Reservoir Chronicle

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. During their adventures, the group gradually grows closer to the point that Fai jokingly labels them as relatives. As they travel, they learn that the feathers have their own unique abilities and can bestow several supernatural abilities to those who possess them.
