Sophita is the robot’s version of the 60’s hippies—live for the moment, express your feelings uninhibitedly, toss all caution into the wind—except that instead of fucking, she prefers fighting.
The whole episode is better understood, once we substitute each instance of the word fight with fuck (or shag if you’re British). Go ahead, watch the episode again with that in mind.
Case in point:
See how that all make sense? 🙂
Even the contrived ending is illuminated. Just like the hippies have found out by the 70’s about the vanity of their vices, Sophita discovers that
sex fights cannot satisfy, and Casshern realizes that he needs not to fuck fight. Not that I know what that means: my life is still at minute two of the show: me desperately looking for someone to fight with. *sob*
