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)

Set in the year 2004, Binzume Yousei is a slice-of-life fairy tale that revolves around four fairies, each represented by four unique colors as seen with their magical bottle jars. These fairies are the extremely peppy Kururu, the reserved and feminine Chiriri, the samurai-loving tomboy Sarara, and the quiet yet quirky Hororo. Fascinated by the human world, these fairies arrived from the fairy world in hopes of participating in the annual traditions and overall way of human life. However, they have a very limited understanding of the human world. Luckily, they are befriended and guided by two humans—"Sensei-san," a university student who they live with, and a first-grade girl they call "Tama-chan," who is sometimes as naive as the fairies themselves. Though these bottle fairies have strange ideas and sometimes have difficulty understanding this new world, they try to make the most of the human experience in their own cute little ways.
