To be honest, this series has really grown on me. The story is really good as well as the characters. However, there is some criticism regarding to this ova special. Yes, it adds more depth to the characters and some plotlines that we actually care for it. The problem with this special is that there isn't anything happening or provide from it. We get a backstory and that's it. Also, the pacing is a bit of concerning and a little bit jarring. Regardless, if you really want to love this series, you should watch this as well. Overall, I give this a straight 7.
