[404 SPOILER] Minor question
The place where Hawk and Akatsuki are staying in 403 and 404 seems to have a significant bone or skeletal motif in the architecture. Now, in 403, I just thought it was the skeleton of a large animal, but in 404, it was shown to take part even in the chair Sasuke sat in.
What I'm wondering is whether it was plausible/possible that they are staying at a place that used to belong to the now extinct Kaguya clan (the ones with a kekkei genkai for manipulating their bones)?
but I dont think you should think too hard into it. I doubt that It has anything to do with the Kaguya, they were only brought in for a short time in the manga, and played no real important role.
