I would put it down to something even simpler - street yukkuri are likely to know only the street life, with human refuge as their main source of food. To find a place without humans, even if they come to believe there is such a place, would likely seem suicidal due to a lack of food.

Ah, but the only difference between a pedoAlice and a normal Alice is that a normal Alice withholds city-sect love towards koyukkuri. Clearly then, pedoAlice is far more city-sect than normal Alice.
Posted a thread about it on the forums, but got no response. Am wondering what to call the yukkuri version of Toyosatomimi no Miko - I find it hard to imagine "Toyosatomimi is Toyosatomimi, take it easy with Toyosatomimi!".
It shouldn't be too hard to get any pet yukkuri to say "Kodoku" a lot, but it would involve neglecting it to the point that it vocalizes its feelings of loneliness, and thus probably doesn't count.
