This chapter reminds me of a rather infamous episode of Wedding Peach, haha. It's the one where the villains infuse rice with "the essence of fatness" in the hopes that all the girls who ate it wouldn't be loved anymore. The only difference with this chapter was that, once the spell was broken, everyone immediately went back to normal.
Either way, I didn't like this chapter very much. Probably because I'm overweight myself, but it was just very... Bleh.
