@LuffyIsGay Blue spirit and nano machine aren't the same thing. This mc didn't know sh** about martial art until his grandfather died. He is someone who perfects a skill if he sees it once. He subdued a demon that entered his mind to consume him before he met her. He also subdued her when she tried to take over him. He was already a monster that was sealed before he met her. So no, blue spirit is not in anyway similar to nano machine.
