We begin this episode with the demonstration of a new Daidouji Brand prototype portable karaoke mic, perfect for picnics like the one Sakura and her friends are having. While ostensibly there to view the cherry blossoms, Syaoran is viewing Sakura the human girl, and when she looks back he can’t help but blush and turn away. Every episode it seems there’s a little reminder that his feelings for her are slowly but surely growing.
The star of the karaoke demonstration is the daughter of the woman whose company made the mic, but when Tomoyo is practicing for a chorus recital, a Clow Card overhears her and steals her voice! Suddenly the school’s best singer can’t even talk, and Sakura blames herself for not finding and sealing the card before it could cause trouble.
Tomoyo goes home and ends up taking a sick day, and her mom Sonomi also takes the next day off to spend time with her daughter. Tomoyo puts a brave face on this incident but she’s no doubt frightened of never being able to speak or sing again, and her mom knows the power of simply being there for a hug. Back at school, Sakura is down in the dumps and wondering what to do, and Syaoran is worried about her, and volunteers to help her search for the Voice card.
They go to Tomoyo’s house, but his compass doesn’t turn anything up; once Voice has a voice it likes, it goes into hiding. Hours pass without progress, and Sakura voices her frustration and guilt, seeing as how this is the second time Tomoyo has fallen victim to a Clow Card; the first being when Song copied her voice.
That gives Syaoran an idea: lure Voice out with Song, who still has that copy. Sure enough, Voice can’t resist Song’s Tomoyo-like singing. Syaoran traps it inside with magical talismans, and Sakura returns it into its rightful guise.
Tomoyo’s voice is restored, and Sakura embraces her, tearful with relief. All that’s left is to sit back and listen to Tomoyo’s delicately gorgeous voice at the recital as she knocks her performance out of the park.
While there are many friends in Sakura’s orbit she holds dear, there’s no one more important to her than Tomoyo, who in turn loves Sakua so much even without a voice she was urging her to cheer up. When Sakura is happy, Tomoyo is happy, and vice versa.
