meh i was thinking about a few things now from the series xDDD
first thing was.... Nia as the Helix King's daughter right... who is a spiral knight... then how come Nia is a messenger of the Anti-Spirals? does that mean he did the naughty deed with an anti-spiral? OO;;
then... the first episode showed Rossiu was in the gigantic spaceship with simon... (i can't remember the name)... but in the series, Rossiu was still on earth though... did they happen to decide to change the storyline in the end?
And if the moon was originally the Helix King's spaceship, why didn't he go get it back from the anti spirals before simon pooned him?
oh gee... why am i thinking of these things? XDDDD *btw that last one is just rhetorical

The anti spirals chose Nia I think because she was the lover on the hero, you know an extra knockout hit and the like
Not sure about the second one.. I know the directing staff cnahged part way though
Well he wanted to be defeated, he was tired from moping for 1000 years
