This will be part of a series. Possible inspirations for Mr. Kishimoto.
Many jutsu's, and KKG's can be found in this manga as well, for instance: Suigetsu's waterbody, Zetsu's merging with the ground, and wood, Shino's control of insects, Jiraya's manipulation of his hair Kidomaru's spider threads spitting from his mouth.
All in all, this is a great manga(only 34 issues). Naruto for adults, as it contains quite some nudity, and even rape attempts...
