Several hundred years in the future, the resources of the Earth runs out, and the progression of the human race has stagnated. The world is now divided into "Units." A boy named Hajiki Sanada lives with his mother and sister in Unit 74, in a place called "Night Town," in which all electricity is shut down at midnight. The key in this story is an object called the GAD. GADs have the ability to reconstruct materials while reacting to feelings of an organic life. The size and shape of the resulting product seem to be different depending on the kinds of feelings that the life possesses. When Hajiki comes in contact with one by accident, it transforms into a huge robot—a Tekkoudo, or "Iron Giant"—which Hajiki names Lightning. And soon he realizes that he isn't the only one with a Tekkoudo, and must find out how to deal with those others who he feels are the "same" as himself. (Source: ANN)

For this year's Nadeshiko Festival, Sakura Kinomoto's elementary school class is presenting a play. She will portray a princess who struggles to respond to the love confession of the neighboring country's prince. Sakura empathizes with her character all too well, since she herself still owes an answer to the boy who confessed his love for her four months ago. When cousins Shaoran and Meiling Li return from Hong Kong to pay a surprise visit to their friends in Japan, Sakura receives further encouragement to finally declare her feelings. However, she is repeatedly distracted by a presence reminiscent of a Clow Card as well as unexplained disappearances around town. Eventually, Sakura learns of another of Clow Reed's creations—the "Nothing"—which was formerly sealed away beneath the magician's old house. It has power equal to all 52 cards Sakura possesses, and furthermore, it wants to take those cards away from her! Objects, space, and people disappear from Tomoeda with each card that is stolen. Sakura sets out to capture the Nothing so everything will return to normal, but what must she sacrifice in the process?

Ureshiko Asaba, 26 years old, married. Few people know the fact that she is a magical girl named "Agnes", and she is actually the guardian of the town where she lives. One day she meets Sayaka Kurenai, aka "Cruje", another magical girl appointed by the magic realm as the legitimate sucessor to her position, but Agnes is reluctant in letting her assume because she knows that Cruje has orders to erase the whole place, including its human inhabitants with the purpose of creating a new one. To complicate matters, Ureshiko must deal with the growing distance between her and her husband, Tamotsu, her crescent feelings for Tatsumi Kagura, a young man who is now living as a tenant in her home, and the fact that in the moment she ever kisses a common human, she would lose her powers forever.
