Drawing on CLAMP's own personal experiences, The One I Love provides insight both into the creators' own lives, and into the oft-elusive concept of Love itself.

This intimate collection of short stories and essays doesn't skirt issues at the heart of the matter such as insecurity, honesty, distance, independence, age, and - of course - marriage.

This one-volume anthology comprises 12 individual stories, each of which consists of seven pages of manga and two pages of prose.

Hikaru Shidou, Umi Ryuuzaki, Fuu Hououji are on a field trip to the Tokyo Tower with their respective schools. The girls are blinded by a flash of light and hear a voice calling for the Legendary Magic Knights to save Cephiro. They fall through the sky into another world, Cephiro. Once there, they meet Master Mage Clef. Clef explains, "In Cephiro, one's will has the ability to change reality for better or worse. The dark fears in people's hearts become monsters, while a well-intended wish can do miracles. One person, the Pillar, whose will is stronger than anyone else's, is responsible for maintaining through her prayers the well-being of Cephiro."

In the first story arc, the current Pillar, Princess Emeraude, has been captured by her high priest, Zagato. The three girls are charged with the task of saving the Princess.

Magic Knight Rayearth follows Hikaru, Fuu and Umi along with their friendly sidekick, Mokona, on their quest to save the mystical planet of Cephiro.

In CLAMP's take on the Alice in Wonderland saga, Miyuki finds herself in a world which seems to be populated solely by a series of scantily-clad women interested exclusively in exploring her charms.

From Clamp no Lumiere:
Murikuri is the story of a popular pig, a pervert santa claus and his high school girlfriend, nice aliens and many more... It does not make sense and I would advise you to not try to understand it. Murikuri is to CLAMP what special halloween is to the Simpsons, a collection of short gags.
