Okay so this entire OVA was really... weird? It literally didn't tell us anything about the story (which it obviously can't go into detail about anyway since it's an OVA but a little bit of background would've been nice I guess) and it was pretty oddly paced too. The animation was decent, which is probably the only thing it has going for it at this point. If they come out with a full series for this I might watch it, but I still can't really get over how they're all wearing skirts over pants for some reason. Also, the voice acting was pretty good. Asalways, Terashii is awesome, and Yuki Kaji uses that really annoying voice that he does sometimes (that seems to fit hair clip boy) and idec about the other VAs, honestly. But yeah, if you want to kill time and be really confused, watch this OVA.
Just as an added side note, there was this random scene where Terashii's character pulls a sword out of Yuki Kaji's character and it was super... awkward? it was just so random like, you can't pull your sword out yourself? Okay.
