lol I've noticed his different outfits too but some are just so hard to see any meaning in them >_>
Thus far looks like with the first picture we've discovered(or just made a theory lol) that Kozi has his "Soul splitting from him" and looking down into sadness. The butterfly body is most likely to be obvious of standing for Kami. So he's obviously sad about Kami dying and it like a part of him left his body when Kami died. Also appears as some one else stated "Into the light". Kami is dead and he "went into the light"
What about that butterfly body being the only one there? Was it that Kozi felt as if he was left alone in the world for some time? Or maybe Kami when he passed away? The solitary being there also has to stand for smoething right?
And what does his shadw shape look like? It kinda does look like a previous outfit. What was MM's last song before Kami died? Maybe something like that? Or Kami's/Kozi's favourite song and the outfit they wore for it? I may be taking it a little too seriously but this is fun decifering what this means XD call me a Geek if you want
lol And I just now found a picture of an outfit for Momento >_>; I think its the one used in his CD cover or whatever... It WOULD make sense anyway lol
