I really love how dark this gets. This poor child assassin really has issues but the fight scenes are both quickly paced, really bloody at times, and brutal. I have to give props to the artist, they sure know how to do a good action scene. I also like the relationship between the two main leads, as he's almost a grandpa/father figure to the girl. I really dislike the unneeded panty shots, but this is Japan, and it won't stop. That much I can count on.
