These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.

Hollywood Pudgy: Sawa starves herself in episode 7, and begins to weaken a bit as a result during choir practice. Taichi asks if she's on a diet, and then comments that she doesn't seem fat and how girls seem to worry about their weight, to which both Konatsu and Wakana start berating him for being insensitive. It's likely she's doing it to lose weight so that she can reach her goal of being a jockey, as they often have to be as lightweight as possible to compete.
Confirmed in episode 8, but the fact that Sawa might grow taller still hinders her goal.
