Honestly, I really liked this volume. Did the plot advance significantly? No. Did I enjoy it despite that? Yes. I really enjoy slice of life/shenanigan-based series with female leads, especially because of the amount of yuri flirting present in this volume.
I do agree that the plot shouldn't come to a standstill for multiple volumes. On the flip side, if the plot advances too fast (think of Mushoku Tensei turning points or Conqueror of the Dying Kingdom) that's an absolute drop from me.
In the end, the thing that was most annoying about this volume was the bickering with Victorica. We could have removed that from the volume to improve it 5 fold.
