Naruto – 666 Satan Summary Naruto: 9 Bijus 666 Satan: 10 Angels, 10 Demons Maincharacter is the container of... Naruto – Kyuubi (The Nine-Tailed Beast, the strongest Biju) Jio – Lucifer (FKN Devil, strongest Demon) In Naruto Akatsuki is collecting the Bijus to create a powerful weapon, in 666 Satan .. OH WAIT.. Zenom is collecting all Demons while the Stea Republic is getting their hands on the Angels. At the end of 666 Satan you find out that Shin is some kind of station which uses all the Demons and Angels to create something you might knows as Armageddon. Jio can stop this by sacrificing himself. We don't know what will happen in Naruto, but there's still some time to go till the end of the Manga. There are a few analogies in Naruto and 666 Satan (besides they wore created by brothers :xzaru) The mentioned Angels/Demons and Bijus, Naruto and Jio having a hard childhood and being the container for the strongest spiritual thing out there. Jio follows Ruby Crecent as some kind of bodyguard and Naruto wants to bring back Sasuke. Jios teacher is Kirin, he has got an „evil“ brother whos called Kujaku. In the end Kujaku is a good guy and helps Naruto. Itachi was also seen as a bad guy untill he died and we found out about his secrets. Itachi made Sasuke and Naruto stronger(well, not so sure about naruto. But remember the thing with the crows and the theories about making him stronger to fight Sasuke) Jio also has his personal Sasuke, Jin. Jio and Jin were friends untill Jio killed Jins parents (Jio was obsessed by Lucifer at that time, he also does this – guess Lucifer likes to kill people). Jin wanted revenge on Jio, but Jio made him think about everything and Jin was good again. → Sasuke should become a good guy in the next time again. Akatsuki will catch kirabi-> hachibi and will move to Naruto. In an epic end fight with Madara and Sasuke on his side(lol) he will die but take all the allready collected bijus with him preventing Akatsuki from whatever. You can make a lot of theories based on the 666 Satan/Naruto similarity, but I will stop right here. Thanks for your time and I'm sorry if I wasted it because you expected and Tobi = Madara Ultimate Proof theory.
