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.
What an Idiot: In the second to the last episode, Karin is cornered by her classmates just as she tries to think of a way to transform without them noticing. You'd Expect: She'll have to go somewhere far where they can't see her transform. Instead:She just blurted out she's Buurin to them, resulting that when she transforms, she's stuck in that form.
