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.

Kazahaya is rescued from freezing to death on the streets of Tokyo by another young man his age named Rikuou. Now Kazahaya rooms with him (who he dislikes for his attitude, even though he's grateful to him for saving his life) above the drug store they both work at, Green Drug. Both work for the mysterious store owner Kakei, while putting up with Kakei's "friend" Saiga, who is always teasing them. The strangest thing about Kazahaya's job is that he and Rikuou are often sent on "extra jobs" by Kakei ...which are different and stranger every time, be it to retrieve a book or a girls' school uniform. Kazahaya always accepts the "extra jobs" so he won't end up without money and on the streets again...but he really wonders what the purposes are of these "extra jobs".

Legends say that when it snows, it is because the snow princess is crying. A collection of five tragic tales, all connected by the bond of snow. Shirahime-syo is CLAMP's tribute to traditional Japanese form and storytelling.

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. Needless to say, hi-jinks and misunderstandings ensue as our young heroine attempts to escape their clutches and return to her regular life.
