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.

It's April, the cherry trees are in full bloom, and Sakura has entered Tomoeda Middle School. She's reunited with Syaoran, who has returned from Hong Kong, and her new student life has begun.

The challenge is over at last. All the cards have been captured, all have been turned. The tests are over, or are they? There may be just one remaining, one that may have to be resolved with the heart. Life has been difficult for Sakura and Li since the day Synoran confessed to sakura that he was in love with her, Li finds it difficult to approach Sakura, whilst Sakura herself is torn, not knowing if she feels the same way for Synoran. The two barly exchange words when they return to school, where they are told by Tereda-Sensi that Eroil is transferring back to England. Sakura, Li, Tomoyo [Armed with her camera as always] and Kero head for Eroil mansion, seeking answers, they are startled when the mansion's front door opens by itself, as do all the other doors from within the building. When the final door opens, the four are shocked to discover that Eroile is holding a party for them!

On her way home Sakura bumps into a woman in the street. After arriving at school the next day, Sakura discovers that her math teacher will be on extended vacation and the replacement is the woman she bumped into the day before, Ms Mizuki. During the lunch break Syaoran reveils to Sakura and Tomoyo that the substitute has a strong magical presence and that they should be careful around her. When school finishes Sakura and Tomoyo go to a shrine to pick up a romance charm. Upon arriving Sakura feels a presence. While at the Shrine they also see Meilin and Syaoran. After a brief conversation they are all transported into a labyrinth, it is soon discovered that this is the work of the Maze card. A number of escape attempts using the Fly and Sword cards are foiled. The Maze then starts to change shape and Meilin is separated from the others. While searching for Meilin, they find her with Ms Mizuki and they soon escape the labyrinth with Ms Mizuki's help. The Clow Card is then captured, however it goes to Ms Mizuki who promptly goes on to give it to Sakura.

Christmas is coming, which is also Yukito's birthday, but Sakura is unsure what to get him. She asks Meilin for advise who tells her it can anything because if the person likes her they will like the gift. Sakura asks Yukito to go to the amusement park with her, using tickets given to her by Chiharu. Tomoyo and Kero follow them to film Sakura's "date". Sakura and Yukito run into Syaoran and Meilin. While they are at a cafe, the Firey card appears. Syaoran uses the Time card, giving Sakura time to use Sleep and put everyone at the park asleep. She then tries to capture Firey using Windy, but Firey is a strong attack card and Windy is unable to defeat it. Sakura has to use two elemental cards, Watery and Windy, together in order to capture Firey. With Firey captured, Kero regains a small amount of his power, enabling him to make small fires. Sakura gives Yukito his Christmas present: a doll of himself.

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 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.

Syaoran's feelings for Sakura have been steadily increasing, though he still doesn't understand why, and Sakura remains blissfully unaware of it. Soon Sakura invites him to go to a teddy bear festival with her, Tomoyo, and Eriol. However, Eriol secretly traps Sakura and Syaoran on an elevator, where the two grow closer. Eriol then creates a large hole in the wall of the elevator, causing Sakura to fall through. Distraught, Syaoran calls out to Sakura by her first name for the first time.

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.

Sakura has the same recurring dream she had in episode one, specifically focusing on the boy wielding a sword in Chinese clothing. She hears from both Cerberus and Yukito that it might be a "foretelling dream". A new transfer student arrives from Hong Kong named Syaoran Li and is seated behind Sakura. He terrifies Sakura with his glares all day and during recess, he demands Sakura to give him the Clow Cards. On the way home, there is a lighting storm, but no rain. Cerberus explains Syaoran is from the Li clan, a famous family of Chinese sorcerers from which Clow's mother came. The same lighting storm for earlier appears and Sakura deploys to battle the Thunder card. Syaoran demonstrates his command over elemental magic and calls on thunder god to return the Thunder card to its original form. He instruct Sakura to use the Shadow card to encage the Thunder card so it could be captured. Thanks to Syaoran's constant derogatory remarks, Sakura is left feeling upset after a card capture for the first time.

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.

Eroile stands above Sakura, Synoran, Kero and Tomoyo, and reveals the truth at last: He is the reincarnation of Clow Reed himself! He then casts a spell that eclipses both the sun and the moon. This puts those not entuned with magical power to sleep. As Yue and Toya race to the shrine, Toya collapses, with no power to call his own any more, the spell is able to affect him also. Eroile then challenges Sakura to use her abilities to break his spell of Darkness or everyone will sleep forever!

She uses the shield card to protect Synoran and Tomoyo and uses the jump card to get closer to Elrole, but the sorcerer summons a fire spell to drive her back, Skaura falls backwards, Synoran uses wind magic to catch her, but in doing so, drains himself of all his remaining strength. After further battle, and more card changing, Sakura realises that only the power of light can shatte

During an attempted card capture, Kero and Syaoran were holding down a card (CHANGE) that took form of an animal. Sakura turned it back into a card, but because they were both touching the card at the same time, Kero and Syaoran swapped bodies. Kero tried to make it though a day as Syaoran without anyone noticing, but didn't do very well. At the end they finally change back when Sakura used the CHANGE card.

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.

Remembering his promise to Meiling that he would be her "fiancé" until he found someone he loved more, Syaoran calls her to tell her that he is in love with Sakura, though he is taken by surprise when Meiling arrives in Tomoeda for the day. While Meiling spends the day with her old friends, the group is attacked by a set of enchanted penguin statues at the playground.

Toya and Yukito are starring in an independent film directed by Nakuru for their school fair, and Nakuru gives Sakura a role. Sakura later begins to notice that Yukito is losing his power and is starting to fade away. Things come to a head when Yukito passes out and falls of a veranda while shooting the film, though he is saved by Toya and, secretly, Sakura. Toya finally manages to tell Yukito the truth about his power, telling off Nakuru when she attempts to interfere. In order to maintain Yue's power and existence, thus allowing Yukito to survive, Toya sacrifices his powers to save him, though losing the ability to sense when Sakura is in danger. As such, Toya has Yue promise to protect Sakura, as well as himself. Having overheard, Sakura realizes that Toya had indeed known about her secret all along. She confronts Kero about why he didn't tell her about Yue/Yukito; Kero explains that he did so to prevent her from blaming herself, since her power alone wasn’t enough to sustain him, and thus act irrationally because of it. Not wanting Yukito to disappear again, Sakura resolves to confess her true feelings to him.

After viewing Nakuru's film, Sakura tours the high school fair with her friends, while Toya comforts Yukito when he appears troubled by the fact that he is not human. Alone with Yukito in one of the attractions, Sakura tells Yukito how much she likes him. However, Yukito gently rebuffs her, saying that her love for him is merely platonic, and that he already has someone he loves; Sakura, in a rare moment of insight, realizes that person to be her brother, Toya. Yukito tells Sakura that the person she loves most is still out there when Sakura senses Clow Reed's presence once more. Using the Maze and Illusion cards, Sakura manages to trap the presence and discovers it to be coming from Eriol, though she loses consciousness. Eriol jumbles her memory of the discovery, acknowledging that she has indeed grown powerful to find him. Sakura tells Syaoran of her experience with Yukito and, despite her understanding and acceptance of the matter, begins to cry. Knowing that now is not the time to tell her that he loves her, Syaoran comforts her and assures her that she will find the person who she loves the most.

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.
