If you don’t already know what ova’s are, then allow me to explain. It’s basically just extra episodes of an anime or movie, it could also be a special type of episode. There aren’t a lot of these because they’re just extra and aren’t usually important.
I personally think that they should make a lot of these for each anime because they’re funny and interesting. I believe that these ova’s can be better then a lot of the episodes from the original ones from the anime.
That’s honestly what I think, I suggest that if you watch anime then to check out the ova’s because they’re awesome. Okay bye!
