Subaru Sumeragi is the 13th head of the Sumeragi Clan and a most powerful onmyouji. Subaru is hired to exorcise a construction site, but his employer mysteriously died. The only suspect is a man who repeatedly walks away from situations in which he should have died. Then Subaru meets a young woman intent upon cursing the man, saying that he killed her brother. Subaru must figure out how his employer died and fight the evil spirits that are protecting the man with the help of his friend and twin sister, Seishirou Sakurazuka and Hokuto Sumeragi.
The two OVAs don't relate to the amazing manga so the storyline isn't really there to what Tokyo Babylon is really about which is what the manga is about. Overall I give it a 7/10 because it was still quite fun to watch, but I highly recommend the manga, it's brilliant!
Despite being a huge fan of Subaru and Seishirou, I never got around to see the OVA up until now. It's an extra story for the ones that read the manga and has two pretty good episodes, but can never reach the level of the manga. The bond between Subaru and Seishirou are almost non-existent in this adaption. It's fun to see the characters coming to live in early 90's setting. And to see Subaru and Hikoto wearing their various (flashy fashion) outfits of the manga in the anime. Overall, the two stories were interesting as a stand alone, but nothing too special.
If you are a huge Tokyo Babylon fan, see this episode. If not, just read the manga and you'll be happier. Or watch some episodes of Tsubasa and X if you want to see Subaru and Seishirou come to live in anime style.
