Carl Kimlinger of Anime News Network published a positive review of the complete anime series. He wrote that the premise can push its dramatic moments a little too far and almost nothing happens throughout the first half of the series. Regardless, Kimlinger praised the plot's character development, saying that it saves the first half with its progression through little events; he added that the dramatic scenes are nicely underplayed to help viewers care for the characters. Kimlinger wrote that Brain's Base and director Tarou Iwasaki provide the series with a style that's perfect, calling the minimalist backgrounds evocative with the right mood and the character animations superb saying "that makes the show what it is: a sleeper delight, plain and simple."
