I can’t say I was all that entertained by this episode. On the one hand the humour was lacking, but on the other hand we get some plot development. If it wasn’t for actual plot development this would have been an episode worth passing on. So we learn why Ayumi’s sister, Mirchiru, is so keen on preventing her sister from breaking the curse. It’s not a unique reason by any stretch of the imagination, but it does make sense why she would do this to her sister. We also see that Haruo indeed does have dormant magical powers. From what we could see it looked pretty powerful. The last thing worth mentioning is Hongou-sensei. It seems pretty obvious that she knew all about Ayumi and the others, but we knew nothing besides that. It seems like she does have pretty powerful magic as well to be able to turn back time.
