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.

It is revealed that the Ryanban has a secret weapon which is in the form of a mysterious witch, named Kiishimu. Syaoran is still determined in getting into the castle that has Sakura's feather inside. Though he was hurt from the previous battle, he still plans to go inside.

Sakura wakes up after fainting and thinks she sees the Princess. Syaoran and the gang go check with Mr. Grosum if he has one of Sakura's feathers. They search his home to find clues of Sakura’s whereabouts until they're interrupted by Mr. Grosum. Sakura tries to find a way to escape from the room she's in. Meanwhile Syaoran discusses a plan with Doctor Kyle about stalking Mr. Grosum's house. As Sakura escapes, the ghost of the Princess appears to Sakura and tells her a story of a mystical feather came into her possession and how it wards off evil. Syaoran then uncovers the truth and finds out that Dr. Kyle knows where Sakura and the children are.

Syaoran and Kurogane go to a sword shop. Kurogane buys a longsword named Sōhi (Blue Ice) and Syaoran gets a sword called Hien (Scarlet Flame). After they buy the swords, Kurogane tells Syaoran not to unsheathe the sword yet because he isn't ready to use it yet. Fay buys a piano for The Cat's Eye but he doesn't know how to play it. Kurogane begins training Syaoran on how to counteract him being blind in his right eye by learning how to balance between his left and right side. A strange woman comes into the The Cat's Eye and starts asking Sakura where she's from and why she's here. Sakura goes into a trance and the woman starts playing the piano and Sakura starts singing. At the end of the episode Sakura is seen inside an egg shaped pod.

Seishirō attacks Fay after he asks if Kurogane and Syaoran live there. It is revealed that Seishirō gave his right eye to Yūko to obtain the power to travel between dimensions but unlike Mokona he can only use this power a limited number of times. Fay gets cornered and is defeated. Seishirō uses Sakura's feather and the people in the world start disintegrating like a computer program. When Syaoran and Kurogane get back to The Cat's Eye they find out that Fay was defeated by an Oni and that Sakura may have been taken captive. When Syaoran finds Seishirō and asks him what happened to Fay, he tells him that he killed Fay. Seishirō stabs Syaoran in the chest with a weapon made from Oni. Syaoran starts disappearing but then Sakura comes running out and hugs him and they both disappear.
