Zenchou (前兆, Zenchō, Omen) is a powerful technique which combines Ninjutsu and Genjutsu. It works through association, allowing the user to control the opponent if they are skilled. Whatever the opponent unconsciously connects one thing with soon follows, from the instant the technique is activated. Josho, with his years of study, can manipulate people well, and determine what the technique will next cause, by prefacing it, and suggesting things to his opponent's mind. After the ruse is revealed, a simple touch by Josho can deal all the wounds that they received from the technique, except these are real, meaning that they receive the wounds once physically, but twice mentally.
