From originality point of view, “Iriya no Sora, UFO no Natsu� is by far within the top of my most original anime list. It is the best science fiction anime I have seemed after “Voice of a distant star�. If you like a good science fictional drama, you would definitely love this anime. The complex relationship between the characters and the innocent romance is underlined by a mysterious unknown war, and it really emphasizes the preciousness of their bond. The nature of the romance between the main characters is unique by itself. They have known of each other’s feeling, but they are still keeping a distance. The curiosity of wanting to know how the romance will end is enough to keep anyone on their toes waiting for the next OVA to come out.
