lol... from all i've been hearing about the ending.... it really does suck but it wasn't as bad as i thought it would be. just be a total pessimist when you read it and it should come out better than you expected.

2 things I don't understand.Why people say crappy ending, and why they say it's better than Naruto. Well, if you're looking for a formulative action-fantasy shounen then this might be better than Naruto, but the ending (imo) worked in line with the story. But it did seem pushed.

If you've read several action-fantasy shounens before, you'll like this if you don't mind the stereotypical shounen stuff. But if that's not the case, 666 Satan isn't providing you anything particular.

I liked the manga. I really did. And then the mangaka drew that crappy ending. That was a HUGE disappointment for me.

I'm going to be generous with my score, since I actually liked this better than Naruto at first. And at any rate, I still like this way better than Bleach. Haha.

This series had one of the most confusing stories I've ever read in a manga. It's a mix of sci-fi and fantasy. They were obviously trying to explain the scientific elements, but that was a waste of everyone's time because half of the stuff that happens are fantasy. Everything was also rushed. Barely half of the angels/demons were introduced.

At one point i liked this better than naruto..although there are cliches, its a shounen...so get over it...yes the author is related to that of naruto, yes there are many similarities..personaly i think they should have made this into an anime instead...but well, what can you do. Overall the story was pretty good..the time skip was better only b/c the characters looked better..the ending IMO is the only thing that fell apart..it just seemed so sudden to end the story..

666 Satan was the type of shounen manga that was associated with the like of Naruto/Bleach/One Piece, sadly it just fell short, in terms of plot, character development, and just looked like a major rip off, considering that he is the the twin brother of KISHIMOTO Masashi it didnt exactly bode well that they had a similar train of thought. The main character "Jio" was a practically Naruto, all that was missing was that he didnt say dattebayo every single minute. Sadly, this manga had great potential, had the writer just dared to be different and veered from that whole i will conquere my inner demon cliche. I think overall the mangaka did not execute what he wanted to do with his characters and therefore did not execute the way he wanted to tell the story. Up until the huge time leap, that came from no where, the story was pretty decent and just fell apart continuing to its demise as the ending ensued and a cr@p load of loose end were left unanswered. I give it a 7

At first I didn't like the art, the girls were drawn really badly (even though their boobs are huge, they looked fat at times because of the size of the thighs and such...). After the time skip, I believe the art looked nicer, but that's the only good thing about the time skip.
The story was super complicated, with everyone's background magically intertwining, and always being in the same location, at just the right time.
I found the story interesting at first, with the different o-parts (made me think of Dark Cloud, where you find weapons, or have your own and upgrade them to a certain degree), but the story always felt rushed, and some battles ended inappropriately (super hyped up character, fight ends with the dog beating it, or something).
It was okay, but with majorly powerful characters, sucky bad guys, rushed and diappointing ending, and cliche sayings about togetherness that would even embarass Captain Planet; some people might want to steer clear.

For the majority of the story it's a fairly standard Shounen. Every character has their own set of gimmicks, secrets and hidden pasts that come up at just the right time to save their ass or advance the story and the story falls back on old standards like training and tournaments. The story starts to get more interesting and unique after the time jump but the time jump itself seems out of place. Right at the end several new characters are introduced and integrated into the main cast but before they're allow to develop the story is over. The the last 3-5 chapters probably contain about 25-50% of the whole story which makes me believe that the ending was rushed for one reason or another. There are also many similarities to Naruto but fortunately it's art style more than anything, the story and characters are far better. Overall it's a fairly standard Manga; if you choose to read it you won't be disappointed but if you don't you won't be missing out on anything major.

I enjoyed this series while I was reading it, but I got the feeling it ended too fast, it should have been longer. The art is great and the story is really unique, and I recommend it for people who like to think, and also shonen fans. ;]

What got me hooked on it was the whole o-parts thing, so I kind of missed that it wasn't more about o-parts out into the timeskip and stuff. >': But in the end I just couldn't stop reading. The humour is great and the characters likewise, but I have mixed feelings about the ending. It's definitely really different than Naruto, even though it's a bit like it in the beginning. But overall, it was an OK read. :]

It was really gripping and with nice action! Even with the similarities to Naruto (twins do think alike I think) it really IS a nice, unique story.
The ending wasn't THAT bad at all! Questions unanswered? Yes, but come on! This gives so much more imagining from a solid ending! You could just wonder about how everyone ended up... it was great!
The Angels and Devils thing (Kaballah) was not that confusing... I quite liked how it had a modern feel but was regarding something very ancient.

(I think it deserves something like a... nine? But a nine point five because people are saying bad things about the awesome ending -_-)
