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.
Your typical jumping through the trees panels:
Sucking up victims: Kamuii(the brutal version everyone talks about)
And what would a ninja manga be without powerful eyes to manipulate the opponent?
All in all, this is a great manga(only 34 issues). Naruto for adults, as it contains quite some nudity, and even rape attempts...
