I love your story.

Wonderful... simply wonderful.

Nami's daemon changing shapes once more after she finds her peace with the Strawhats, this just matches so well. Perfect! :-D

This fits.

Indeed.

Lg, Ysaye

I read that he settled as a rat, and I was going to review saying that a cat is actually the animal that represents Nami, and then I wisely refrained, because Atsumeru did settle once and for all as a cat. I would understand Zoro as a wolf, though if I remember correctly he's represented by shark and tiger. Luffy's is self-explanatory. Usopp's sea bird... I would probably say an Opossum because it plays dead a lot.
Anyway, really nice job. I love His Dark Materials, though I haven't read the series in a long time. Maybe I should reread them, just because. :D

Ohmygod, you have no clue I love this crossover you're doing. None whatsoever, please keep it up. I'd love to see a more Luffy or his brothers focused one, but since you're the author, anything you give me that is like this I will be completely content with.
