Each episode has two titles: one is the original Japanese title, and the second is an English title that was chosen by Japanese studio Gainax itself. Most often, the official English title is not a direct translation of the Japanese title. For example, the direct translation of the Japanese title of episode 2 is "Unfamiliar Ceiling", but the English title is "The Beast". Sometimes, however, the two titles are either similar or exactly the same, as was the case with episode 10, "Magmadiver". Many tracks on the original soundtracks are named after the English episode names in which they are first used.
