You’re not good at foreshadowing, are you? It’s usually details like this that can hint at what will come later on in many stories.
There’s 60 chapters out though and as far as I could tell it’s just more lighthearted stuff.
I know this is just supposed to be fun and games, but it is a little bit odd that a grown man has a picture book. I’m getting the vibes that he probably had a daughter and a wife or something, but they either divorced and moved away, or worse died in an accident or something.
Typical power creep.
Remember the arrancars in Bleach? They were supposed to be the toughest of the toughest. And in the end of their arc they were all defeated without anyone breaking a sweat. It was embarrassing really.
It also signifies that Frieren is part of the holy wand court, and in direct opposition of Serie’s association. Which might be another reason Serie kicked her out.
