Similarities to Naruto
This manga and its characters have similar traits to the manga series Naruto, mainly because the creator is Seishi's twin brother, Masashi. When 666 Satan was released in Japan it was accused of being a copycat to Naruto.[2] This can be explained by the fact that the two are brothers. In turn, both share similar influences and similar artistic styles. Both manga were deeply influenced by Akira Toriyama's Dragon Ball and have incorporated many elements from it into their own stories.
Examples of similarities between 666 Satan and Naruto include, but are not limited to:
* The main character of both stories lack parents; and substitute others for parental and familial figures. Naruto shares this trait.
* Both protagonists in each manga (Jio Freed and Naruto Uzumaki respectively) have a very powerful demon inside of them (both the most powerful of a series of demons in each series), such as Naruto's Nine-Tailed Fox and Jio's Satan.
o Jio and Naruto both share certain physical characteristics of the demons they each play host to such as Naruto's whiskers, eyes and canine teeth and Jio's half-white hair and one red eye.
* Hard childhood is important for the storyline of both Naruto's and 666 Satan's protagonists. Both Jio and Naruto start friendless because of the demons inside of them which cause them to be shunned by society in general. Both come to the "conclusion" that they need to become the strongest person around, in order to conquer the world/ become hokage.
* Both Naruto and Jio were trained by hermits, Jio by Kirin and Naruto by Jiraiya. Jiraiya and Kirin look somewhat alike, with long silver hair, and both are very strong.
* Neither Naruto nor Jio can control his demon.
o Both have had outside influence in learning how to suppress their demons (in a literal sense).
+ Both stories also have organizations trying to capture these demons.
+ Both Jio Freed and Naruto Uzumaki have "talked" with their demons and in some cases, even had altercations with them.
+ In certain instances, both Jio and Naruto have had to make use of their demon's power.
+ Kirin (666 Satan) and Kakashi (Naruto) have each lost their left eye and are in possesion of a unique eye (The Cyclops Eye and the Sharingan Eye respectively)
