No, it's okay. The NH-33 article is somewhat more dense feature-wise than the NH-29 was, and since not many of my Miharu NPCs are actually NH-33, I haven't bothered with minutiae like that. I just went for what I found relateable (based on what I wikipedia-ed), which was that spacy nekos are likely made to resist exposure to vaccuum more (the NH-29 came shortly after Hanako died of hypoxia/asphyxiation, so, that was a concern) - so, the reminder is cool to have.
