Cardcaptor Sakura, Book 6

Sakura has finally found the last Clow Card, but capturing it won’t be easy. The more cards Sakura collected, the more powerful the remaining ones became, meaning this will be the strongest card yet. But as she’s about to find out, capturing all the cards isn’t enough to stop Evil from befalling the Earth. Sakura must also confront Yueh, the judge, in what may well be her final trial.
