The girls of St. Trinians are on the hunt for buried treasure after discovering headmistress Miss Fritton is related to a famous pirate.
The episode begins immediately after Kurogane has killed King Ashura, activating a curse placed upon Fai by Fei Wong Reed to trap them in Celes Country using Fai's own magic. Fai's remaining magic is insufficient to send them all to another dimension, so he tells Kurogane to leave him behind. Kurogane refuses, and cuts off his own arm in order to sacrifice the necessary magic. They arrive in Nihon Country, Kurogane's home world. Princess Tomoyo tells Kurogane that he has begun to understand the meaning of true strength. The hunter Fuuma arrives with an artificial arm for Kurogane from Yūko, paid for by Fai's remaining magic and Tomoyo's dreamseeing ability. Fellow hunter Seishirō arrives in search of the vampire twins Kamui and Subaru. Syaoran attacks Seishiro to reacquire the feather of Sakura's he was seen with in the Ōto arc. Syaoran seizes the feather and is transported into the world of dreams, where he meets Sakura, Watanuki Kimihiro, and the clone Syaoran, whom he prepares to fight.
The episode continues where the previous part left off, with the Clone Syaoran entering the Dream World. Watanuki is then transported away as the battle between the two Syaorans begins. The Clone gains the upper hand, and manages to knock the original Syaoran out. When Sakura attempts to protect him, the Clone stabs her but finds himself unable to kill her. He teleports her out of the way before taking the feather, but Syaoran awakens and stops the Clone as they reappear in Nihon. The two Syaorans attempt to take the feather and kill each other, but Sakura appears in the way and is impaled on Hien. She declares that she too is a Clone, and that the true Sakura is waiting for Syaoran, before dissolving into Sakura petals. Dr. Kyle appears and takes Sakura's soulless body to Fei Wang, and the Clone vanishes in anguish. They learn from Yuko that Fei Wang is in Clow Country, and that Watanuki, Syaoran's other self, paid for this information with his memories. The group then prepares to depart for Clow Country.
