Let me say this first, Saying this series is exactly like Hellsing isn't true, while it does have the feel, but Stories aren't the same. It does have two characters that remind you of two characters in Hellsing but overall, everything is original.

Story - 7
The Story is kinda lacking especially since its feel like there should have been more but sadly there isn't "for reasons". Its very interesting but it may leave people confused

Art - 9
The Art is awesome, How the characters look and Feel is very well done

Enjoyment - 10
Battles are awesome, and the World is very interesting. Jin-Ho, really out done himself with them

Overall - 9
If you can look past some hiccups and enjoy some really cool battles, characters and world. You'll like this manga. If you like Supernatural mangas like Princess Resurrection, Hellsing, and etc, then give it read. The Story may be lacking a bit for some, but its a good read
