It's the new term, and the hot topic at school is clubs! Sakura and Tomoyo decide to join the same clubs they did in elementary school, cheerleading and chorus.

It's been raining buckets all day. Sakura and Tomoyo take shelter in a park on the way home from school, and suddenly the Key of Dreams at Sakura's chest begins to shine... Is it the work of a card?

A new transfer student named Akiho Shinomoto joins Sakura's class. She's just arrived in Japan after living overseas, so her Japanese is still very stiff and formal. Sakura invites her to eat lunch with her group, excited to make a new friend.

Sakura is having a flower-viewing party with her friends Tomoyo, Syaoran, Chiharu, Naoko, and Yamazaki, as well as the new transfer student Akiho.

Sakura continues to face the hooded figure in her dreams. At school, everyone says they want to hear Akiho sing again after being charmed by her voice at their flower-viewing party, so they meet in the music room after classes are over.

Sakura and Kero-chan visit Tomoyo's house to test the abilities of the Record card. Tomoyo's mother appears and gives Sakura an enthusiastic welcome, then the girls head outside to test the card.

Sakura finds out that Akiho has moved into the mansion formerly inhabited by Clow Reed's reincarnation, Eriol. She pays a visit with Tomoyo and meets Kaito, the butler who's been taking care of Akiho since her childhood.

Sakura is visiting the Tsukimine Shrine market with Meiling, Akiho, and the rest of their friends. She enjoys a day of browsing the many shops and stalls on the grounds along with Akiho, who's never seen a Japanese shrine before.

Sakura has been invited to Tomoyo's house, along with Meiling and Akiho. Tomoyo says there's something she wants to show them and leads everyone to her home theater, where she plays the video of a play they were all part of in elementary school.

Sakura manages to capture the card that showed up at Tomoyo's house, but her relief is short-lived. As they're returning home, Sakura and Meiling are suddenly attacked by a mysterious girl in the road!

Sakura is finally about to go and read to children with Yukito, and she invites Akiho, Syaoran, and Tomoyo to come along. Sakura's enthusiasm convinces Akiho to join her for the reading, while Syaoran agrees to contribute a piano accompaniment.

Syaoran meets Kaito through a chance encounter on the way home from school. He informs Eriol, whom he's beem secretly keeping in touch with, and they both begin to suspect Kaito is a very powerful magician.

Sakura is overjoyed to see Syaoran's cousin, Meiling, make an unannounced visit from Hong Kong. Meiling asks to stay at Sakura's house, so they head straight there. Meanwhile, the power Toya lost by giving it to Yukito is gradually starting to return.

Today is the cooking lesson in home ec class that everyone's been looking forward to. Sakura's morning is thrown into a panic when she forgets her apron, but she and her friends are excited to make roll cakes in class.

Sakura has seen the mysterious robed person in her dreams many times. It turns out Akiho has been having the same dreams herself, and she's grown worried over their unsettling contents.

Sakura's grade goes on a field trip to pick strawberries. Sakura and Tomoyo bump into Yukito and Toya who are working part-time at the strawberry field. On the way to the greenhouse, Syaoran senses something from the storehouse, but Meilin pushes him along. The class enters the greenhouse and begins picking strawberries. Sakura hears the door to the storehouse will not open, but when she and Tomoyo go to investigate, they find it open. Syaoran and Meilin come into the storehouse, and Syaoran says that he feels a strange presence. The door suddenly closes and locks them inside. Syaoran informs the group that it it the Lock card that has trapped them. After Rika, Naoko, and Chiharu come to the storehouse, they go look for Ms. Mizuki and tell Toya and Yukito. While looking for a key to unlock the door, Sakura sees Ms. Mizuki through the window, who gives her a hint, but Ms. Mizuki then disappears. Sakura realizes that Ms. Mizuki was trying to tell her to use her key. The Lock card shows its true form when Sakura tries to put her key into the lock. Syaoran seals the exits and Sakura quickly seals the Lock card before it can get into the keyhole. Toya, Yukito, Rika, and Naoko come into the messy storehouse, now that the Lock card has been captured. Sakura and the others clean up the storehouse together. Sakura's group learns how to make and bakes desserts with strawberries. After the desserts are made, Sakura brings a piece to Toya and Yukito.

Sakura has a fever, but goes to school anyway because of a group project. Later, Sakura gets dizzy and is sent home with Toya by the nurse. Toya stays home to watch over her. When Toya is making food for her, Sakura senses a Clow Card, and it turns out to be the Cloud card. Sakura uses the Mirror card to make a clone of herself, so Toya will not notice that she is gone. Sakura, using the Fly card so she can capture the Cloud card. Toya comes in Sakura's room with food and offers it to Sakura's clone. Sakura travels toward the Cloud card, but when she is blown off her staff, Syaoran saves her with a wind spell. Sakura learns that Syaoran and Meilin are going after the Cloud card as well. Back in Sakura's room, Sakura's clone asks for the medicine and Toya replies that she should not take medicine when she is not sick, because she is not Sakura. Toya asks the Mirror card to hide the fact that he has a vague idea of what Sakura is doing and the Mirror card agrees. Back outside, Syaoran hits the Cloud card with various spells and gets it to its original form and Sakura seals it. The card is Syaoran's, but he gives it to Sakura. Sakura returns to her room and falls asleep in her bed. Nadeshiko appears and heals Sakura. She tells Toya that she was a bit worried and then tells Sakura to do her best, before disappearing. Sakura's father appears saying that he was worried about Sakura because she was acting strange this morning, and Toya tells him his hunch was right and that mother appeared. The next morning, Sakura is as cheerful as ever, and her father is home helping make breakfast. Sakura thanks her mother for staying by her side.

Sakura, Tomoyo, Meilin and Syaoran head into town for a day of fun. The four are not alone in their venture as the Dream, in the form of a butterfly, tags along. When the group enters Tokyo Tower to see an exhibit there, Sakura falls under the Dream's spell. At first, the vision that the Dream presents to Sakura is comical. Later, the Dream takes a more serious tone by expanding upon Sakura's reoccurring dreams concerning the Clow guardians' Final Judgment. Sakura becomes frightened of the images of this future, however, the Dream flashes clips from Sakura's past to remind Sakura of all the obstacles that she has overcome. Outside of Sakura's dream, Syaoran realizes that something is wrong and uses the Time card to freeze the Dream card. Snapped out of the Dream's spell, Sakura is able to successfully capture the Dream card. However, as it was Syaoran that stopped the card's effects, the Dream card belongs to Syaoran.

Ms. Mizuki announces that the class will by doing a play for the school arts festival. Sakura realizes that the woman she sees in her reoccurring dream is Ms. Mizuki. Roles are assigned by amida drawing. Sakura has the role of the prince and Syaoran is the princess. The two have lunch with Yukito, who asks about the play. Sakura and Syaoran are too embarrassed to tell him what roles they are playing. They agree to practice their lines together in the morning at school. Toya makes Sakura breakfast and warns her about doing "reckless" things. Sakura meets Syaoran in a hallway and the Sand card rushes around behind them. They practice outside and almost get to the kissing scene, when the Sand card forms a vortex around them. They get away using Fly, but Syaoran gets caught in the vortex again. Sakura uses Watery and Syaoran uses Freeze to freeze the Sand. Sakura seals the card and it comes to both of them, but she lets Syaoran have it.

Sakura and Syaoran are working hard at memorizing the play. Finally the day of the play comes, and after a few denials about going out on stage from Syaoran, the play is on. The play goes well until right before Sakura and Syaoran kiss, when the Dark card appears. Sakura is almost lost in the Dark card until she realizes that she holds the Light card in her heart. The two card counteract each other and show themselves. Sakura seals both cards and before being sealed, they tell her that the final judgment is coming and that is will be up to Yue.

Meilin gets a call from her mother, who wants her to come home. Meilin tells Sakura the next day that she is going back to Hong Kong next week. Syaoran appears, and asks Meilin if she told the teacher she is going back to Hong Kong yet. Meilin asks Syaoran if he feels she is getting in his way, and Syaoran says that is not it. Meilin runs off, calling Syaoran an idiot. At the end of school, Sakura invites Meilin to her house and they have a chat with tea and sweets. Sakura tries to make Meilin feel that she is not a nuisance to Syaoran. Meilin tells Sakura about how she fell in love with Syaoran. In the middle of their conversation, Sakura senses a Clow Card. Meilin decides not to go, but Sakura drags her along and tells her there are things only she can do. Meanwhile, Syaoran is getting beaten by the Twin card. After a couple of failed attempts, Sakura thinks that Meilin and Syaoran can work together to keep the two bodies of the Twin card immobilized, so she can seal them away; they try it, and it works. Sakura seals the Twin card, and it goes to Syaoran because he and Meilin weakened it. Syaoran tells Meilin that he never thought that she was in his way. Sakura, Tomoyo, and Kero go to the airport with Syaoran to say goodbye to Wei and Meilin. Meilin asks Syaoran if he remembers the promise, which is until Syaoran finds a girl he likes more than her, she will be his bride. Meilin whispers a thank you to Sakura for saving them with her magic, before she leaves.

Sakura once again has the dream in which she is facing the Tokyo Tower. She clearly sees Ms. Mizuki, but this time, Mizuki is accompanied by another figure with long hair and wings. She wakes up early to see Yukito compete in an archery competition. Sakura explains what she knows of her dream to Kero before running down to make breakfast. She meets up with Syaoran and Tomoyo at the archery competition, and Kero tags along too. At the archery tournament, Sakura finds that Ms. Mizuki is one of the challengers and ends up in the finals alongside Yukito. During the fierce match, Kero pokes his head out of Sakura's bag upon sensing tremendous magical power, shooting a piercing glare at Ms. Mizuki. Sensing his gaze, Ms. Mizuki loses her focus and the tournament. Later during lunch, Sakura discovers that Kero is missing from her bag. Searching for him, she is astonished to find him in the middle of a private conversation with Ms. Mizuki. While walking home, they run into Toya once again, this time dressed in a bear costume giving out balloons. After he leaves, there is an earthquake, likely caused by the final Clow Card.

The earthquake was caused by the Earthy card. Ms. Mizuki is nearby, but there is nothing going on around her. Sakura uses to Sleep card to put everyone except herself, Kero, Tomoyo, and Syaoran asleep; Ms. Mizuki is not affected by the card, however. Sakura uses the Fly card to see from above; while Syaoran makes sure everyone is safe. Sakura eventually uses the Woody card to seal it away. Now with the final card in her possession, Kero is able to transform into his true form. After a short celebration, Syaoran explains that Kerberos, representing the sun, is one of two guardians of the Clow Cards, the other being Yue the judge, representing the moon. Kero explains that the sole owner of the cards will be determined after Yue appears. Suddenly, Yukito magically floats with a light blue aura, and turns into Yue. Ms. Mizuki explains to Sakura that Yukito is Yue. Yue begins the Final Judgment of Syaoran, who tries to fight Yue with a seal, but Yue tells him that it is useless, and he can only use the Clow Cards he currently has. Syaoran tries to use the Time card, but since it is under Yue's jurisdiction, Yue can use it against him. Syaoran is defeated, and it is time for Sakura's Final Judgment.

Sakura initially refuses to fight Yue, but after he repeatedly attacks her she tries to find card that can confine him without hurting him. She uses the Woody card, but it is a card under Yue's sign of the moon, and he turns it against her, and Yue declares she has failed. Sakura learns that if she fails the Final Judgment, everyone who has ever had anything to do with the cards will forget their feelings for the person they love the most. After seeing a vision of such a world, Ms. Mizuki uses the bell to enable her to break free from Woody's hold. She explains that her bell was created by Clow Reed to give Sakura another chance. Ready to try again, Sakura releases her wand and it transforms, the end changing to a Star. She call's Windy, which Yue denounces as being under him as well, but this time he is unable to turn it against her and is captured. Sakura expresses her understanding of his love for Clow, promises to try her best, asking if they can be friends rather than her being his master. Yue declares the trial successful and acknowledges her as his and Kero's new master. Sakura has a vision of Clow Reed who thanks her and explains that her power is of the Stars, rather than the Sun or Moon. Sakura celebrates with Tomoyo and Syaoran, while Kero and Yue chat briefly before they return to their false forms.

Rain still falls on Tomoeda. In her kitchen, Sakura thinks about the previous night when she was unable to release her key into the staff. Touya comes downstairs and notes that she's up early as well as calling her a monster, but is visibly concerned when Sakura makes no retort. She asks him if Yukito was going to visit their house that night and he tells her that Yukito hadn't planned on it, but that he would probably come if they were having something good for dinner. In Sakura's room, Kero thinks about the strange presence he sensed the day prior, hoping it wasn't what he thought it was.
