The story at first seemed a bit boring, but I quickly changed my mind as I watched more. In fact, this is one of the most original ideas I've ever seen. The characters and story are well developed even though there are only 3 episodes.
The character designs are really nice, and the animation is nearly perfect.
The music in R.O.D. reminds me of 70's spy/action/cop shows. I guess it's ok though...
Avery unique concept...The whole idea with the Ijin's, TThe Paper's, and Mrs. Deep's powers, are original, amazing, and very unique.
Overall (84/100) 8.4
Overall I strongly recommend you wath this OVA series.
