With the final preparations complete – in the form of an episode of down-time – Eureka Seven is finally ready to begin its ultimate confrontations. Renton is going beyond the Great Wall to find out some kind of truth, Stoner and Holland are preparing their expose of the Coralians and Eureka, and Dewey is planning his own operations to bring an end to the Coralian “threat.” The shift in focus is established with a new opening theme tune, probably the best of the series’ four themes. The theme tunes and credits sequences have throughout the series tonally reflected what is happening – the third, the punk-esque To the Centre of the Sun, played through the series’ impetuousness and kicking out – and now Sakura, the fourth theme, comes with its very heroic and spiritual sound for the show’s climax – established as something that must be religious.
The William Baxter episode of Eureka Seven offered an, at the time, different take on religion within a setting which had hitherto presented it in skewed terms. It presented personal faith – a desire to do right – as something linked to self-reliance and isolation, as opposed to a view of organised religion that was intractable, morally apart from society (in the episode in which Renton encounters a conflict surrounding medical treatment going against religious views) and most of all viewed with suspicion. Even as Holland works to help the Voderak and save Norb from Dewey, it is out of a sense of humanitarian duty and the need for information and allies – he is standing up, where it is profitable, for people. Yet episode 37, the first half of which is an extended debate between Norb and the eccentric scientist Greg Egan, sees Holland apparently embracing the Voderak viewpoint.
