a world in which ninjas can use chakra to create jutsus and perform superhuman feats by increasing their physical abilities with taijutsu, using ninjutsu to control the five elements (fire, wind, electricity, earth, water) or genjutsu to create illusions in the mind of your opponent. These ninjas organize themselves and found so-called Hidden Villages that receive mission requests from other inhabitants. The five largest and most important of these villages have a Kage as their leader, who is the strongest and most qualified ninja for general command. Originally, jutsus were supposed to be used to pacify the world, which was dominated by chaos and hatred, but some ninjas started to create and learn jutsus for their own benefit and even to do evil, causing an imbalance in the ninja world. There are also the so-called Bijū, creatures with immense power that, in order not to cause destruction, are sealed inside people called jinchuurikis.
