What language is that?

Thai, I believe. I know we have at least one translator around here who's been doing the Miku Plus comics, which are in Thai.

I'm not the only one around here translating Thai, I think. Also, if I knew the context behind the picture, I should be able to make better sense with what she's saying. But I don't have a pixiv, y'see, so I can't check out the link or the artist's comments.

@Disoriented: You see, the title is "konpui 01"; the commentary is not there at all and the only user comment is "Cute!" in english.
