Jio's friend Ball always dreamed of being strong--strong enough to help the resistance movement stop the maniacal governor Jaga who has a stranglehold on his hometown, and strong enough to defend his friends and his sister. Now that he too is an O.P.T., it looks like Ball might stand a chance! Can he, a novice when it comes to O-Parts, defeat a powerful member of the Zenom syndicate single-handed?
He is the younger twin-brother of Masashi Kishimoto (creator of Naruto). The two have been drawing manga together since early childhood, thus their styles are similar. As a result, the two have frequently been accused of copying the other. Seishi, himself, notes that the similarities are not intentional since they were both influenced by many of the same things while the more famous Masashi even asked fans stop calling Seishi a "copy cat". Seishi created the manga 666 Satan, which is serialized in Japan by Monthly Shonen Gangan and licensed by VIZ in America as "O-Parts Hunter".
Love it :D 666 Satan (which is the original titel for O-Parts Hunter) is definitely one of my favorite mangas :D It's written/drawn by Seishi Kishimoto, the youngest of the kishimoto-twins (Masashi being the eldest, and the author of Naruto), which is why it might seem similar to Naruto. However the storylines differ a lot from each other - even though they've got quite the same plot. But in terms of stories, I believe 666 Satan is way better than Naruto, and I'd like to recommend it for all shonen / action lovers :D
