Tsubasa RESERVoir CHRoNiCLE - Season 1 - Eps 15: The Believing Heart
Sakura tries to escape from the forbidden castle with ghost Princess Emeraude's help. She also brings the children along with her. Meanwhile, Syaoran and all the townspeople want to hear Dr. Kyle's confession. He then confesses that the kidnapping was his doing and he used the children in order to break the feather free. The children escape from the castle but Sakura is still trapped. Dr. Kyle escapes from the townspeople and decides to grab Sakura instead, but suddenly Syaoran comes to rescue her. The castle begins to tremble as the reservoir from the river overflows. While they confront Dr. Kyle, the wall of the castle suddenly breaks and smashes into the doctor. They are freed as they see the castle collapse, and the townspeople thank the group for rescuing their children. At the end of their journey, they realize that they are being watched by someone who is also interested in Sakura's feather.
