Alrighty then.
Genjutsu,or Illusionary Techniques are techs that require chakra and hand seals just like Ninjutsu.Genjutsu is rather different than Nin and Taijutsu.Genjutsu puts the opponent into an illusionary state,rather than attack the body directly as with Nin and Taijutsu.Genjutsu manipulate the flow of chakra in the opponents brain thus putting them in the illusionary state.It is used to change the victims surrounding or make them think they are in pain.They do not get actual injuries from the attacks but only think they got.One can be freed from the genjutsu by doing one of the following:
1.Inflicting pain to themselves (stabing their hand,leg)
2.Infusing foreign chakra into themselves.
3.Use Kai,or better known as Genjutsu Release.
Several recognizable users of Genjutsu:
Itachi Uchiha,Kurenai Yuhi,Tayuya etc.
Hope that is enough
