I stumbled around this anime ova this morning, and I could say that I. F*cking. Love it.
According to another YouTuber, you couldn't really find a legal way to watch this since it is deemed unpopular and the vhs didn't sell well at that time (it's a 1999 or something production) and thus the production stopped at act 2 (the time for the OVA is 40 something minutes), and it is hard to come by, even on the pirate sites (I haven't checked it yet).
You could only find the manga to know the continuation.
As for the story. I could only say that it is so awesome and hilarious (in a sad way) because the scary faced MC is misunderstood by everyone thus the comedic effect.
This is the type of manga/anime that will make you hovering in between laughing your a*s off or ended up feeling sorry for the MC.
I'm falling to the former category. (I just have this kind sense of humor. :3)
Anyway, I highly recommend this OVA, and now I'm off to look for the manga~
PS : oh by the way, you know claymore? That author is also the author of this series.
