This OVA acts as a comical side story. Its acts as an interlude to just simply relax and watch the darker than black characters.
As it was simply just one episode, there was not a developped story. The comic relief was well made and I passed a good time watching it. I particularly liked the otaku room and characters ( is it me or the anime that the two girls crave on looks like Host club?!)
And the heck? Stalking the beautiful collarbone guy? That was funny !
The characters, the music and opening were the same than the ones used in the series.
If you enjoyed the Darker than Black series, I recommend checking this one out too. It respect the vibe of the series and add a nice touch of humor. I liked it very much.
Score: 4/5. The same as the series.
