I liked this OVA alot better than the Haru one. The only issues I have with it are the fan service with Asuna is kinda over the top, but besides that it's pretty decent, and can I just say that Nodoka looks so CUTE in her outfit in this.
This OVA has alot of fan service as I said before. Besides Asuna they have it a little for Nodoka as well, as well as most of the girls there (as for the fact there all wearing swimsuits)
