When you first pick up this manga, you will probably come from the idea of Seishi being one of the Kishimoto brothers and you want to read some shounen. Well, that is a fair reason to get there. However, when you read 666 Satan(which i would like to call O-Parts Hunter because of the terrible name) you will see it is more than your typical shounen manga.



Seishi Kishimoto goes to extremes when he is using the religious idoms and thoughts, you will find Jio more complex than most of the shounen heroes. Of course it has it is typical shounen moments but it is shounen so what else to expect? The main reason i love this manga much more than all the shounens out there is the fact that it has a detailed and actually smart story telling.
Jio sometimes can be very annoying, but his mindset is so emphatically explained that you end up liking him anyway. As you see him grow up with every chapter you and his interact with his "inner self" you get the feel that he is really a part of your life.

Seishi is more fair-hearted when it comes to women than his brother but he still lacks the talent to objectively describe any deep feeling of female characters which is like the only minus of this manga.

The art is your typical shounen art, lots of exagerations and drama, but you will find it more detailed and creative than the most.

I need to say this manga is must read if you are into shounen, and looking for something more intense than the mainstream ones. I suggest you at least give it a try, after first few chapters it gets more interesting with each one.

Maybe in the end you will find yourself-like me- questioning why this manga never got an anime adaption, after all there are very terrible shounens out there.
