I was looking forward to this OVA to continue the story of Asobi Asobase. But it was a bit of a let down to be honest. There were only two vignettes, neither was that strong, but the second one was definitely the weakest. It felt hard to make sense of what was going on without any context. We were thrown right into the teacher's past with her past classmates without any introduction. I was definitely thrown off for a loop because I didn't understand that we had time skipped to the past 15 years. I thought it was another group of 3 teenage girls. Ittook me a while to piece together that this was the teacher from 15 years ago. A heads up about that would have set my mind in the right frame, and maybe I would have enjoyed the act more. Still, they weren't as crazy as the 3 girls we were used to. So it wasn't as great seeing their story unfold. Though it was funny to me personally to see old references.
Still, enjoyable, but I wouldn't say this was a great way to finish the series.
