Basically, it is the same structure as the series were. However, as this is an ova it does not contribute to the plot.
Ayumu is stuck in a mess after going about his daily normal life again. This OVA lets the watcher let loose and just have fun. Great comedy, art, sound and animation.
It has little fanservice but it is mainly to benefit the comedy of the OVA. It is definitely a worthy watch if you enjoyed the original series. However, if you dislike the comedy and are searching for a nice story ( IMO it is a nice story:p) with a lot of complications this
is not it.
Oh, it's that time of the year again when you realize that there's nothing much happening in your life. But then, something unexpected happens. It's something that you least expected. It's something you never expected the unexpected.
Kore wa Zombie Desu ka? of the Dead once again returns to present to us viewers a fun little ride that some of us may or may not miss from this previous series. The cast returns with Ayumu and his friends. It's the usual gang involving the tsundere Haruna, the sadistic Seraphim, the cute Eucliwood, the self-proclaimed wife Yuki, the butt loving Sarasvati, and the shy girl Taeko.
some of your memories, Aikawa Ayumu was once an ordinary boy but was later revived as a zombie by the cute necromancer Eucliwood Hellscythe. From there on, his life becomes anything but ordinary. But that's just the tip of the iceberg in this OVA. You see...or maybe you don't (literally), in this OVA, Ayumu's life is turned into more chaos especially after he drinks a certain product when he's tired.
Yes, in this OVA, Ayumu becomes the unseen. He's become a lot of things like a zombie, magical girl, and now one more to add to that list. Boy, I wonder how his life went straight to hell like this.
The guy never gets a break but he didn't expect this.
Of course in modern series' OVAs, there is a lot of things to be expected. OVA that spawns from main series typically has the beach, onsen, summer festival, or one of those fan-service bonuses. Obviously, Kore wa Zombie Desu ka? of the Dead is no exception. So, expect fan-service involving boobs, model poses, and nosebleeds. Well, there's no tentacle rapes in this OVA but there are butts; the butts that Sera adores so much.
The music of the series remains relatively the same. "*** Passionate (***パショナート)" by Iori Nomizu remains the same that depicts one last time a montage of the series' characters. The artwork remains the same as well being generic and that zombie like feeling presented in a comedic way. The sadistic like expressions and the moe figures of Haruna are still there. Along with that package is Ayumu's little unseen journey with his delusions.
Overall, I would say this OVA was okay but lacked some features. It had some unexpected moments but that was of course, to be expected.
