[hide]Gotta disagree with you there, I don't think the ending was meant to have a winner, they purposely tied to show how meaningless their battle was. Throughout the story they'd fought each other even though their enemy was common and they were being used, the last episode where they tear up each other and the army was a message of backlash and freedom.
I think of it much more philosophically than just oh they got mad and wrecked shit, it was about being free, and the freedom of battle.
While you fight you are free, you may lose, you may win but in the end even in death you are free, because you faught and did not give in. I dunno maybe I'm reading too much into it, but I think in a perhaps even psychotic way the creator was trying to show the pure unfiltered truth of the fight.
The fist at the end showed that they would never stop fighting and that they'ed battle forever, it wasn't about winning or losing but simply about fighting, that was the only way Kazuma and Ryuhou could communicate without the influence of friends/organizations/wars/good and evil getting in their way, it's how other animes/movies use love as the common language that can get through even the most horrid beasts, in this they used the fight/battle w/e.[/hide]
It's been a while since I've seen the show so I appologize if I misname something like the organization Ryuhou fought for (w/e it wasn't the army)
