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.
Family Unfriendly Aesop - A given considering this is a show involving angels and devils. Too many to list, but chief among them is an episode where Raf gets punished after she and Sulfus (her devil counterpart) are seen together without being told what exactly she did wrong, implying that if someone says you did something wrong, then you must accept the consequences no matter what, even if you aren't told what you did wrong exactly. Sulfus went through the same thing mostly, but this trope still applies since it implies that a girl being together with a boy (or vice versa) is "giving in to the devil" (which the so-called "VETO" also implies).
Hollywood Pudgy: In episode 4, Urie worries about her weight despite being drawn with the same skinny-build as her friends. Raf and Miki are understandable confused by this. However, Cabiria gladly makes fun of her.
Narm - At times. Mostly due to the jarring voice acting in English.
