Tsubasa - CLAMP

The odd group of dimension travelers arrives in a country full of magic. They seek a book that may hold the key to finding one of Princess Sakura's powerful memory feathers. But the volume they need turns out to be a national treasure, off limits to the public. Now Syaoran, Kurogane, and the others must brave traps, ravenous beasts, and some of the universe's strongest magicians in order to steal the book. When it comes down to enchantments versus martial arts skill, can the team pull off the biggest caper of their career so far?
