It almost has to be. I think everyone who read the original manga is going to look at that panel and go, 'wait a minute...'
Some really gratuitous cheesecake shots in this chapter. I know it's to be expected to some extent, especially with the original series as its groundwork (there were plenty of shots of Kiriko in her underwear, and of course the ever-growing exaggerated proportions), but that one crotch shot really stood out as utterly unnecessary. At least in the original series, Kiriko and Celine got presented as skilled chefs first, eye-candy second, but that seems to have been reversed at least as far as the art goes here.
