Ringo will become the New LunaAnd her title will be The Sun That Was Called Moon That Was Called (Ringo) Starr.
Ringo is Leda's daughterSupported by the fact that she seems to be growing.
It's Dante's Divine Comedy with robots, and the first 9 episodes represent the circles of Hell, with the ultra depressing episode 9 being the center of Hell. The series is similarly called "Sins" because it deals with the theme of Sin, Atonement, and Redemption as did the three parts of the Divine Comedy.
Casshern also killed Princess Luna.Oh come on. This one was just BEGGING to be posted.
At the end of the series everyone is immortal.The Ruin kills everyone, both human and robot, so the only ones to survive beyond the series are those that are explictly immortal (Casshern and Luna) and the robots that Luna cures of the Ruin. Eventually, only Luna and her subjects would be left with Casshern around to make sure they don't take their eternal lives for granted. Thus, the series is a Reconstruction of Living Forever Is Awesome; if you have all the time in the world, then do something productive with it.
