Ok, to be honest I just was expecting a cheap-gore OVA like Genocyber. But I was given a very good story with a few gore scenes. Story: Not the most original story in the world (also I think it was inspired on Devilman only with a biological focus) but it was pretty good. The existence of demons explained from a scientist point of view. Hey, thats something that we dont get everyday. But thats just a combination of the ideas of mythological and biological monsters in one sotry. It doesnt make it original but still a good idea Characters: Too simple but it doesnt make thembad characters. Sometimes they look very unexpressive but thats because they show no fear about the monsters. And thats make sense. Why you should be scared about something that you are researching? About the developement of the characters, its not very good but I cant complain about it. We are talking about a story of 59 minutes, not 822 episodes, just as an example.

Soundtrack: no comments. Just awful

Technical work: Very good. Nothing to be surprised. We are talking about Madhouse studios.

Recommended? 50/50. Just decent.
