Except even in the original visual novel Katarou gets used to the dogs - even prior to seeing the leaf dragon and actually progressing to a character route . He doesn’t completely sperg out every time he sees a dog.
Granted, it’s only his second scrape with obviously supernatural foes in the anime, and it’s his first time seeing one of those dogs in particular, which is why I said it was just a little weird as a small footnote at the end of a paragraph. I mean, there’s a lot of other things I could nitpick about the dog scene (like Kotarou rewriting himself to chase after Kagari with minimal amounts of internal debate, but not rewriting himself when he literally thinks he’s perilously close to death). Generally, my larger point was that the impact of the first dog appearance didn’t feel like a big deal compared to the first time he sees a dog in the VN. Midou just summons the dog and it immediately goes chasing after Kotarou - there’s no steady buildup as Kotarou goes from confused but curious to straight up terror.
