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.
YMMV: Shukufuku no Campanella
Moe: Pretty much the main point of the anime. There is a plot somewhere, but it's buried under heaps of moe, at least for the first two-thirds of the series.
