The year is 2019, and all single-season anime series have decided to announce a squeal. Idea Factory has decided to hop on the bandwagon, and I assume the meeting must have gone something like this:
"So we should bring back one of our series for a second season, but Mars of Destruction and Skelter Heaven were complete failures. Oh, we have the Neptunia series that aired back in 2013, and it has become much more successful after we released the games on Steam in 2015! But we're not comfortable sponsoring a whole season 2 yet, so let's just make a second OVA for it to test
the waters first."
Since Hyperdimension Neptunia was one of the first anime that I've ever watched, I couldn't pass this up. So after 6 years, how does the sequel hold up against the original? The art style seems improved and more detailed now (I don't think some parts of the original's art are holding up well with time). They've matched the original art style so it still looks like the same series, but they've included blush and more detailed faces.
That's about where the positives end. The animation was only good at best, with a few spots that were noticeably underwhelming (like Nepgear running with stiff arms). The story and development were almost nonexistent, not that I expected much from a single episode, but what was there just felt off. It doesn't help that it follows a different story line than the games. The writing didn't flow well, and several lines didn't feel natural. It even felt lacking in the trademark Neptunia humor.
As someone who has always enjoyed the series despite its flaws, this OVA simply felt like a disappointment to me. I'm honestly pretty confused why they made this random OVA so suddenly to begin with. If this was just an experiment and they are pushing for a season 2 with a story from the Victory games, I would hope the writing would be better but it could have some potential. Unfortunately, this OVA doesn't contribute much interesting to the series, and you could probably pass over it without missing out on much.
