Just to point out, Corpse Party already had an OVA series (it has spooky white hair girl, can't remember exactly) around a few years ago but I'm guessing it probably failed or never continued last time I checked. If you don't know what the series is, it's based on the horror game usually for PSP.
So this OVA is entirely different compared to the previous. The story starts off with a group of high schoolers that magically got transported to a haunted abandoned elementary school. Then their adventures begin since that (just like in the video game).
Anyway, I got to say admit this series is slightly better than the previous OVA along with an interesting opening song. Also the plot and setting is kinda better than the other because the one seems to be random and not explained, really. Other than the high school students fighting for their lives against haunted beings, I do hope this OVA will continue and eventually becomes a full series.
Conclusion: Interesting OVA series so far. Hope it continues...
