Beautifully drawn anime, and thoroughly enjoyed the first episode. I am definitely going to watch this.
I couldn't help but see a black, short-haired, mini-Victorique though. Yune is adorable. I especially enjoyed the interactions between her and Claude.
The OP song was pretty good, too. It's lively, fun, and reminded me of an old French song from the early 20th-century France. After watching the first episode three times now, I can practically almost sing along to it.
Now, I haven't read the light novels yet because I have never seen any translation anywhere, but a couple questions:
Other than that, there were the little things that were cute to see like Yune tapping her feet a few times on the marble floors of the Gallery because she's unfamiliar with the flooring. The way her eyes widen seeing all the new and unfamiliar things around her. I like it.
It is also good that I understand French so I can read the titles, signs and other words in this show.
