Let’s get one thing out of the way, which I believe was an issue I had with Clear Card: Touya and Yukito are way too tall. That, or Sakura, Tomoyo and friends are too short. In any case, the proportions are all messed up. Just take this image: Sakura is standing straight yet the top of her head just reaches Touya’s navel. Even if Touya is six feet tall—pretty tall for a 15-year old!—that would make Sakura only three-foot-six, or nowhere near her listed height of four-foot-six.
But nevermind. What isn’t strange is that her big brother’s best friend Yukito is handsome and kind to Sakura, so it’s understandable for her to harbor a cute little crush on him. Sakura even gladly offers some of her hotcakes (the mix for which she bought with her allowance) with Yukito, while castigating her brother for sneaking a bite.
Yukito repays her generosity by making her dreams come true and taking her on a date, and to one of her favorite spots: the aquarium. Knowing what I know about Yukito’s hidden true identity from Clear Card, I assumed the date was an excuse for him to investigate the disturbance that occurred when Sakura and her class went there on a field trip. A strange whirlwind caught one of the penguin assistants, and then the penguin itself, almost drowning both.
As it turns out, Yukito is just Yukito this week, and just showing Sakura a harmless fun time. For the record, it’s fun watching Sakura react so lovey-dovily and elatedly to her good fortune of scoring a date with her crush. She also learns that Touya works with the penguins, something she sees as a dream job. Both the aquarium date and the eventual breaking of the water tank and flooding of the cafe are elements that are revisited in Clear Card’s ninth episode.
In this far earlier iteration, the cause of the disturbance isn’t the Clear Card Spiral, but the Clow Card Watery, which Kero-chan warns is an aggressive unruly card that Sakura can’t hope to defeat with just Windy, Fly, and Shadow in her hand. Like that episode, Tomoyo records both the date and the battle with the card, and provides logistic assistance to Sakura, in addition to providing her a sharp, jester-style blue battle costume.
Sakura determines that if she can simply slow Watery down she’ll have a good chance to capture it, so she provokes it into chasing her as she flies through the bowels of the Aquarium until it dead-ends into the walk-in fridge—where the penguin food is stored! There, Sakura summons Windy to whip up the cold air around Watery until the card is frozen solid. Now Sakura has two elements to work with, and her first truly offensive card to use against future cards.
