The opening theme "Slow" plays over recycled footage from the first episode, and is more of a love ballad. Episode 14 onwards shows the second version of the opening sequence which portrays more original footages. Whether this change was made due to growing popularity or the initial reception is unknown. The first closing theme, "Carnation", the more upbeat of the two, is set to a small computer animation of Hiroshi dancing in the corner as the credits scroll up the page.
