... What exactly is a Muenzuka? it's does sound like a interesting Location...
It's a region of Gensokyo close to the Great Hakurei Barrier where a lot of lost and forgotten items from the Outside World accumulate, like a large junkyard. Rinnosuke gets some of the wares and curios he sells from there.
Eh?So she came from outside then?That reminds me, the store owner said that it was found abandoned near the Muenzuka.So it either belonged to her when she was still alive or to someone with a connection to her?In any case, it seems that this bear belongs to her.Most likely.Well, we still can't say that much, but for now it looks like she came here looking for that stuffed animal.
