She loved the food: mikan mandarin oranges and kinmedai ("goldeneye tai") fish 金目鯛, in particular.
While she was there, in that beautiful natural setting, self-confessed "indoor girl" Ao-chan drew this excellent personification of the beautiful (and delicious) fish, as "Kinme-chan."
Commenters on 2channel think that her drawing has improved even from the fairly high standard she had before. One commenter said he was a mangaka and she drew better than he did.
This makes me wonder if she is studying art at college, maybe at a graphic arts college. Probably not, since when asked her favorite subject last year, she said "Chinese," and we know she loves drawing.
Ao-chan has been posting frequently to her blog, but I expect that ends with the end of the spring holiday, as she goes back to school.
