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.
Canon Sue: After reading a couple chapters, it's hard to think of Kazuma as anything else.
Ho Yay: Nora and Kazuma (Come on! "I've never had a pet before. It's worth the pain to have a dog of my very own"? How the hell else are we supposed to read that!?); to a certain extent Nora and Barik as well (see Tsundere, below).
Jerkass Stu: Lampshaded by Nora, who notes with growing irritation that even though Kazuma treats everyone like crap, they still love him to pieces
