I have an explanation for how a foreigner would be present~!

Washed up on the shores of Hokkaido, kindly natives took care of her and nursed her back to health, and now she's gone to the 'mainland' (*cough* Hahaha, calling Honshu the mainland...). If anyone would have what she needs to get back to where she came from, it would probably be the guys on Honshu.
