Nebutori

[Marechal des logis Daedalus]

You can see that entire Dōjinshi if you have not already: http://g.e-hentai.org/g/347218/a0eeafa672/

The premise is as Odin described, being a wife who seems to inexplicably gain weight in her sleep, while her husband believes it must be spirits and researches in in a book of folklore. This is essentially an old euphemism for when women become fat during marriage.

It has been so many years and yet still no one has provided a translation. I am very fond of the art style. Her lethargic face gives me funny feelings in an indefinably charming way.
