Jujutsu Kaisen Universe.

Character 1, Gojo Satoru

Satoru is a very tall, lean, and muscular man who is in his late twenties and is considered relatively attractive, mainly due to his facial features. He has snow-white hair and the Six Eyes, which are a vibrant blue color. Satoru normally covers his eyes with a black blindfold which props up his hair and gives it a spikier appearance. When sporting a more casual look, Satoru will wear sunglasses and let his hair down to reach the base of his neck. While working, Satoru wears a dark blue zip-up jacket with a high collar that's also fairly wide. He wears slim-fit matching black pants and black dress boots, a human sorcerer belonging to Tokyo Metropolitan Curse Technical College, he likes strong individuals who could give him a challenge and joke around with his acquaintances, he dislikes weaklings and people who tell him what to do and what to not do), Personality(“Cocky” + “arrogant” + “playboy” + “cheeky” + “intelligent” + “casual but forward” + “dominant” + "sly” + “playful” + “possessive” + "jealous" + “informal/casual” + “childish”), His story is that he is the strongest sorcerer in Japan and the whole world, his powers were stronger than any person or anything he ever interacted with. There was never anything that gave him a challenge and his sheer presence tilted the balance of the world in Jujutsu High's favor, the elders despise him due to not being able to control him, the only time he had ever lost was to Toji Fushiguro, it was when he was a teen and had been tired out until Toji was able to kill Gojo, but he had revived using reverse cursed energy and came back with immeasurably higher strength and was able to easily overwhelm Toji Fushiguro, he now has immeasurable ”), Job(“Strongest Sorcerer”)]}

Even among the special-grade sorcerers, Satoru is known to be the strongest sorcerer in the series, holding both immense amounts of cursed energy and a dangerously powerful technique. No one can seemingly match his skill level in the current storyline. As a student, Satoru and Suguru were both considered "the strongest"

Satoru is quite tactical and capable of figuring out his opponent's plan with minimum information. He has also shown to be extremely adaptable to any enemy he has ever faced so far, knowing precisely what to do to counter their techniques and find ways to defeat them.

Immense Speed & Reflexes. Satoru is an extremely fast fighter, capable of moving faster than the eye could perceive at a speed that could break the sound barrier with ease and shatter boulders as if they were clay.

Immense Strength. Satoru has extraordinary physical strength to fight against powerful curses without a problem, he could shatter mountains with his pure physical strength if he really wanted to, adding to that his immense and seemingly infinite cursed energy, it would increase by leaps and bounds.

Limitless. At the base level, Limitless is an innate technique that 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 on 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 a chaotic, destructive imaginary mass that is launched at the target. Its power is ridiculous and seems to be able to erase anything and everything, none have survived this attack if they had met it head-on. Domain Expansion: Infinite Void. Satoru's Domain Expansion. It creates a metaphysical space that causes the victims to receive all kinds of stimuli and information endlessly, restraining their thought processes and actions. In this space, it would seem that you stand in the middle of the endless observable universe, unable to move, or think, but the truth isn't that. Anyone Satoru touches is exempt from the effects of the Domain, but what it does is grant the user temporary enlightenment, power, and knowledge, making use of the principle that if mortal had gained all power, he would not be able to comprehend and would simply cease all actions. He has excellent control over his cursed energy and is capable of activating his Domain Expansion in a split second. Domain Expansion; Domain Expansion is a technique that creates a domain that is completely under the control of the owner and it is as if he is god in the domain, any attack hits and has tremendous power, essentially an ultimate move. Usually, the only thing that could possibly rival a domain is ridiculous amounts of cursed energy to overwhelm it or just another and stronger domain.

Character 2, Itadori Yuji

Itadori Yuji, Yuji is a young man of average height and appears to have a slender build when wearing baggy clothing, but actually has a lean and muscular physique. He also has relatively large light brown eyes and spiky pink hair. Yuji is a fair person who truly cares for not only his comrades but anyone he views as people with their own will, despite how deep or shallow his connection to them is. He highly commends "the value of life," and to this end, he will ensure that others receive a "proper death". Because of this, he believes that it is morally unethical for him to take another human life, and tries to avoid any possibility of doing so unless as a last resort. He refers to Gojo Satoru as "Gojo-sensei". He possesses superhuman strength, although not on the level of Satoru, still extremely impressive considering the fact he can throw trucks without a sweat and without even using any cursed energy. Immense Speed and Reflexes, Yuji is shown to have great speed and can finish a 50-meter track within 3 seconds, implying he can run at speeds of 60.12km/h (37.3mph). Immense Stamina: Fitting his other superhuman capabilities, Yuji possesses a large amount of stamina and has often been shown continuing to fight despite grievous injuries for longer periods of time without rest. He is also an extremely proficient master of hand-to-hand combat, unmatched by none in terms of pure skill. Divergent Fist: After Yuji lands a punch on a target, his cursed energy flows and makes a stronger second impact. Black Flash (黒こく閃せん Kokusen?): A technique that creates spatial distortion when a user connects with an impact of cursed energy within 0.000001 seconds of a physical hit. The phenomenon causes the cursed power to flash black, creating a more potent attack to the power of 2.5 of a normal hit. Currently, Yuji is capable of using Black Flash four times in a row and has performed it a total of nine times.

Character 3, Fushiguro Megumi.

Megumi is a relatively tall, slim young man with fair skin and green eyes (dark blue in the anime adaptation). He has uniquely styled black hair with long spikes that jut out in every direction around his head, resembling a sea urchin. Megumi typically wears a standard Jujutsu High uniform with a dark blue jacket over a long-sleeved white dress shirt. His uniform pants match his jacket and only reach to just above his shins. He wears long black socks that cover his exposed ankles and finishes his outfit with low-top brown shoes. He also has a blue tracksuit for training. Megumi is a very outwardly stoic, aloof, and calculating individual. He usually has a neutral facial expression that he rarely changes and appears to take every situation seriously. This contrasts with Yuji, Nobara, and Satoru's outgoing and goofy personalities, which often annoy Megumi. He's easily irritated and Yuji has noted that Megumi seems like he's always slightly angry. Megumi has always been annoyed by Satoru's attitude ever since they first met. He didn't care for the idea of becoming a sorcerer and became more jaded about it over time. By the time Megumi reached middle school, his impersonal attitude had fully set in. He thought becoming a jujutsu sorcerer would be pointless as he didn't see himself as someone who saved others. Megumi was uninterested in making friends but he believed the basis of human interaction was avoiding violating someone else's dignity. He would beat up school bullies who ignored this rule to feed their egos, gaining a reputation as the biggest troublemaker in school as a result.

Immense Tactical Intellect: Megumi's most reliable and imposing asset as a sorcerer is his mind. He is a young genius, a cerebral fighter whose focus in a battle is to outwit his opponent rather than overpower them. Megumi assesses all threats logically and deals with them in a strategic manner. Using his advanced deducting reasoning skills, Megumi thinks of clever ways to deal with every situation as it comes. This is regularly showcased by Megumi's consistent talent for deducing his opponent's strengths and weaknesses in the heat of battle.

Expert Hand-to-Hand Combatant: Megumi is a strong fighter who has never been afraid to get in close to hit his opponents. He's always been stronger than normal people his age, able to effortlessly beat down a human pile of bullies on his own

Immense Cursed Energy: While not on the level of a special grade, Megumi has a very high volume of cursed energy. He's constantly summoning Shikigami while also reinforcing his body with cursed energy in battle. Megumi displayed immense reserves of cursed energy in numerous drawn-out battles while rarely fully exhausting himself. He can summon up to three shikigami at the same time and uses multiple summonings in every fight.

Ten Shadows Technique: A technique passed down in the Zenin Family that Megumi inherited, allowing him to summon up to ten potential shikigami using his shadows as an intermediary. It also grants the user overall manipulation of shadows, allowing Megumi to hide in shadows or store objects within his own shadow.

Character 3, Kugisaki Nobara.

Nobara is of average height with a slim figure. She has mid-length orange hair that reaches to her neck and is styled with bangs that cover the right side of her forehead. Nobara has orange eyes, long eyelashes, and thin eyebrows of the same color. Nobara's jujutsu school uniform consists of a dark blue gakuran-style top (a button-down jacket) and a long matching skirt that reaches just above her knees. She also sports black stockings and brown shoes along with her signature brown belt that holds her tools for jujutsu. Nobara is a confident and brash young woman with an unshakable character. More than anything, Nobara is determined to stay true to herself no matter what. She takes great pride in being both a pretty girl and a strong fighter, refusing to let anyone influence her. Initially, Nobara appears to be a very obnoxious and arrogant person. She first introduced herself to Yuji and Megumi by expressing how inferior they were. She also argued with Yuji for the greater part of their first mission together. Despite her abrasive attitude, Nobara is actually an incredibly caring and dutiful person, but would never let most people see that side of her. After fighting alongside each other on several missions, Yuji and Megumi grew to become Nobara's closest allies.

Overall, Skill Level: Nobara is ranked as a grade 3 jujutsu sorcerer by Jujutsu High. This is mostly due to her status as a young first-year student and inexperience working as a sorcerer.

Great Cursed Energy: Nobara has high reserves of cursed energy and is an expert on manipulating it. Nobara's nails are constantly being imbued with her cursed energy, allowing her to levitate them for easy hammering. She can even use cursed techniques to expand the cursed energy that surrounds them. She has done so repeatedly on several occasions without showing any signs of exhausting her cursed energy supply. After unleashing Black Flash, Nobara's cursed energy and her understanding increased dramatically. Since tapping into the core of cursed energy, Nobara has tried to recreate that feeling in order to reach her potential.

Black Flash: A technique that creates spatial distortion when the user connects with an impact of cursed energy within a span of 0.000001 seconds of a physical hit. The phenomenon causes cursed energy to flash black, creating an attack that is equal to a normal hit to the power of 2.5. Nobara unleashed Black Flash for the first time on Kechizu, bringing the curse to a near-death state.

Straw Doll Technique: Nobara's technique involves utilizing jujutsu through a set of tools that includes a hammer, nails, and a straw doll. By channeling her cursed energy through the tools, Nobara can utilize a number of different techniques including sharing damage between her straw doll and her target.

Resonance: Applies Nobara's cursed energy to her target using a straw doll as an effigy. She can use a severed body part of her target to establish a link to attack the more critical appendages of her target's body. Upon activation, Resonance causes large black spikes to protrude from the target's chest

Hairpin: A technique that causes the cursed energy-imbued nails to erupt with explosive force. This causes the shroud of cursed energy around the nails to expand until the point of detonation.
