Even though this disc had 4 episodes, it effectively only had 3, as episode 16 was completely a recap episode. In any case, we finish the first half of the series with the defeat of the Spiral King and his warnings that he was actually protecting humanity, and that once “a million apes” were on the surface, basically something bad would happen. However, beyond this we don’t really know anything, other than the fact that the Spiral King seemed to believe that he was acting as a guardian against Simon’s spiral power.
As for the “7 years in the future” part, it’s going to be hard getting used to the characters being older now. However, the new government under Shion seems to be suffering from the same ills of many revolutionary governments: it starts out strong as a result of the initial enthusiasm and idealism, but soon gets weighted down under the weight of the fact that many of the people leading the nation are neither very competent to do so, and don’t really want to in the first place. While Shion seems competent, he doesn’t seem very enthusiastic, and while others may be enthusiastic, they aren’t very competent. Meanwhile, people who see this, in this case Rossiu, get frustrated and radicalized by the fact that his fellow revolutionaries, well, suck at governing (and, in conjunction with the attack of the anti-spirals, cause mass unrest) and decides to take over the place himself.
I’m still not sure why the anti-spirals think that the spiral energy will cause the destruction of the universe, though I guess my thought is this: if the spirals have a tendency to advance rapidly, and have rather unchecked passions, that could lead to several consequences such as, say, the destruction of their own planet. However, if you expand this thought upward, perhaps they fear that spirals wouldn’t stop at a planet, but might cause the self-destruction of a galaxy or even the universe itself.
In any case, this series seems to have gotten a bit more interesting now that we’re in this new time frame. We’ll have to see if it just resorts to massive mecha battles like it did to begin with, but hopefully the plot will start getting expanded some. There is already evidence that it is, with Rossiu taking over.
