Yeah - same here. There's no break of any sort really - just from one panel to the next we go from one timeline to another.
There's actually been quite a lot of that that throughout the series and it wasn't until late, when character connections started to be revealed, that I realized it. And I suspect that there's been even more of it than I realize - that there are still things that haven't made sense yet because I haven't fitted them into the timeline.
And I also sort of suspect that the confusing timeline isn't just a storytelling quirk and is actually going to be plot-relevant eventually.
When this was announced, I read part of the manga, then part of the LN original, and thought it might be good. I don't normally watch currently airing anime, but I was keeping an eye on this. And I finally dove in and caught up on it last week.
This episode highlighted pretty much everything I loved about the series as a whole.
Anna is awesome. Let's get that out of the way first. She's easily my favorite FMC in years. And she was especially good in this episode. It's just been so pleasant to watch her and Nukumizu get so comfortable with each other, and it was nice to see that in full flower in this episode. And I couldn't help but laugh when she lost her imaginary boyfriend to an imaginary rival.
Kaju is awesome too, and it was great to see a lot of her in this episode.
And the senseis. I would've liked to see more of them all the way through, but at least they got a bit of extra screen time in this episode. They're both interesting characters in their own right, and they have a great dynamic.
Chihaya was especially good in this episode too, even though she only got a few seconds. She's been a pleasant surprise - she just looks so sweet and naive, and she's so very much not.
Overall, the only criticisms I might have of the series are that a couple of character quirks were a bit too exaggerated (Komari's stutter and Yumeko pretty much as a whole) and that it seems like very little was really settled. The pacing wasn't really a problem in and of itself - I actually quite liked it - but it means that we need at least another season, and preferably a few more.
Overall, I was very impressed, and this was a good cap to the season, assuming another season is coming. Without another season, it'll be a bit disappointingly incomplete, but even then, it was a good slice of life.
