I kinda don't like the idea of writing down things like "jojo noices". This thing is, like, for manga fans "who know". An in-joke or something. May be confusing for neophytes. Well, the fact that you kinda explain it in credits alleviates the issue. That you do this as a hobby and don't receive payment for it also counts.
I was kinda surprised to see that Kinka-chan was attacked by the boar. I kinda assumed at this point that, well, they all are shapeshifting kitsune, and, like, they are strong. Against a bear maybe, but boar...oh well, more brownie points for Hachi.
As for Goro, well..a Man always keeps his words
both me and my sister are entirely in cat faction, one of arguments I heard from her once was "also, cats don't eat their own shit"
