seishi kishimoto is the twin brother of masashi kishimoto (author of Naruto). . . unfortunately, masashi is morfamous than his brother. . . i mean both of their works are really awesome but masashi got the break.. 666 satan is an awesome manga series. it's like reviewing dragon ball, naruto and full metal alchemist mixed into one. . . I hope they will release an anime series about o-parts hunter. . . hheheheheh... it's a great work...
