This is a series that gives a mixed impression.
Up to 50 chapters I'm finally convinced that this manga do not meet my taste. This is okay, but not as exciting as I want to see what happens next. I don't think my impression will change much until the end. Says had said what I wanted to say, half of it.
Unfortunately, I don't feel any strong chemistry between the characters. Even I have to admit Naruto is better than this. Lululola also became a rather strange companion and many fanservices too forced.
The author's decreased drawing style gives a quality that doesn't support either, I like how Claymore approaches Berserk and it's very dark and tragic. But since we're talking about Ariadne, this shounen's work is really targeted for young teens so I think it's a good fit. It also seems that the author has to learn more to develop fighting techniques. I find it funny and hard to imagine, and it's not cool at all. Everything looks the same.
7/10
EDIT : I have something to add. Compared to using internal power, natural weapons are better. I want to see Norihiro Yagi use his ability to develop stories with a monster concept. Just like in Claymore, I was struck by the majesty of the character. It's incredible to see the energy released from each revolution, making clear the limits of who is the strongest. It will be interesting if he follows in the footsteps of Attack on Titan.
