Story of a young boy named Kakeru and his adventures together with a magical blue pony named Blink.

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)

Appearing out of nowhere, the silver-haired boy, who can control iron, rescues Mafuyu. Mafuyu finds out that the boy, named Alexander Nikolaevich "Sasha" Hell, is a "qwaser"—a being who is capable of controlling an element through the power of "soma," received through the act of breastfeeding. Confused by the ordeal, Mafuyu attempts to move past it with little luck, as Sasha transfers to her class the next day. What will become of Tomo and Mafuyu's normal school life with the danger of other qwasers looming close to them? [Written by MAL Rewrite]
