Satoru Gojo is one of the main protagonists of the Jujutsu Kaisen series. He is a special grade jujutsu sorcerer and widely recognized as the strongest in the world. Satoru is the pride of the Gojo Family, the first person to inherit both the Limitless and the Six Eyes in four hundred years. He works as a teacher at the Tokyo Jujutsu High and uses his influence to protect and train strong young allies.
Limitless: At the base level, Limitless is an innate technique which is derived from the Gojo family. This technique grants its users nigh-absolute control over space through cursed energy manipulation at an atomic level, resulting in multiple subsequent results and techniques within the overall ability. With the manipulation of space as just the base level of the technique, Limitless has three standard and one "non-standard" form beyond this.
Infinity: Being the neutral form of the Limitless, the Infinity is commonly known as the ability to stop, although this is a common misconception as the true power of the Infinity is to slow things down. When something attempts to hit Satoru, the person or object in question instead hits the infinity between himself and them. According to Satoru, this is the convergence of an infinite series and comes straight from the paradox of Achilles and the tortoise. Akin to the way Achilles will never catch the tortoise due to the potential, infinite amounts of finite space separating them or how the real number one will never touch the real number two due to the infinite amount of fractions that separate them, the opponent will never touch Satoru due to the infinity between them. Satoru can decide what does and doesn't touch him and can do so based upon mass, speed, and danger ratings.
Cursed Technique Lapse Blue: The reinforced version of the neutral limitless; Blue is the byproduct of Gojo amplifying the Limitless and negative energy, producing a vacuum. Through these, Gojo creates a scenario where the world itself is forced to correct itself and fill in the negative space, causing all matter in the range of the commanded space to be pulled together.
Cursed Technique Reversal Red: Being an inversion of Blue, Red has the opposite effect. Using his reversal technique to invert the properties of Blue, Satoru activates the divergence of his infinity and causes an extremely powerful repulsive force, repelling all matter in its vicinity. Being an ability that is powered by positive cursed energy and formed as a reverse curse technique, the ability has two times the destructive ability of Blue.
Hollow Technique Purple: An advanced technique that collides the Lapse and Reversal of the Limitless, resulting in an imaginary mass that is launched at the target.
