It feels like they tried to fit some sort of exposition in at the beginning of the OVA but I found myself quickly lost and bored. Some scenes cut so suddenly and weirdly that I became confused and had no idea what was happening anymore. While the mystery aspect of the plot is nice, there are various things and points I found myself laughing at in how ridiculous they are.
Overall, this OVA is unremarkable. If you've read the manga it's probably more enjoyable, but other than that it's a snoozefest.
