* Why do the Itsuwaribito exiled to Nadeshiko Island have guns and forged weapons? It seems unlikely that they could get them/make them there. On a related note, did they have children? Where else would the children come from (what would they be exiled for)?
* Utsuho has shown remarkable physical strength in fighting off people before. Why is it so difficult for him to pull some small fallen trees off of Pochi?
* How did the hard-core criminals not notice [[spoiler: the village inside]] the massive rock on Nadeshiko Island? It is clearly open from above (because crops grow) and it makes little sense that nobody would have thought to climb it.
