Nanako
This was all turning out to be a surprisingly interesting set of circumstances, actually. So interesting, in fact, that the squirrel girl couldn't help leaning in. After a few moments of leaning further and further in, however, Nanako realized she hadn't accounted for the higher center of balance on the chair an instant before she tipped forward. The squirrel fell forward with a small yelp, ending up in a bit of a tangle, upside-down on the chair, looking up between Shirou, Sakura, and the old man, chest hanging down though it was still contained by her top, tail draped over the side of the chair as she listened intently.
"I'm with Shirou," she piped up, slightly muffled by her top, "Is there a way we can get to the source on this? End the curse itself, hopefully for good?"
