**Kieran Santos** ( サントス ・キエラン, *Santos Kieran*?) is major supporting character of the Jujutsu Kaisen series. He is a longtime friend of Yanhui and a member of the United Society of Cursed Arts as a Lieutenant General.

## Appearance

Kieran is known to be extremely attractive, to the point where Sapphire Rosaria states his only saving grace are his divine genes. He has a well-proportioned muscular, tall, tanned body without too much muscle or too little. He has messy, dark gold hair and multicolored eyes splashed with the best hues of every color of the rainbow, resembling an opal. When attending the Cursed Arts School of California, he wore a black, long-sleeved blazer with the golden emblem of Cursed Arts embroidered on the right over a white shirt. He paired this with a simple black tie as well as black pants and white sneakers.

## Personality

At first glance, Kieran is a charismatic and laidback boy who almost always is wearing a resting face or calm smile. He is extremely outgoing, able to make a friend in mere minutes, and has a dry sense of humor. However, under the mask lies a insecure and manipulative person, refusing to accept that there are people who don't like him. He will overexert himself to please people and is a perfectionist, caused by his fear of abandonment.

The only time a sliver of his true self is revealed is when he's facing someone he doesn't respect or is close to. He has the ability to say and do the most vicious, cruel things whilst still retaining a prim smile on his face and can somehow still make people fawn over him even after they've witnessed his brutal temperament. He is aware of his attractiveness and knows why this is such but greatly abhors the attention he's given, saying it sickens him. When the final straw has fallen for him, he becomes incredibly cold with a stony face and glaring eyes that invoke fear in all.

He never lets his guard down unless he is with a person he trusts and can truly call a friend. Around those he can shed his false persona around, he adopts a more sadistic personality, never failing to tease and make fun of his friends, and broadcasts his love for banter. He is extremely witty and seemingly never loses his cool, even throwing out quips when engaged in combat.

## Abilities & Powers

    **Overall Skill Level**: Kieran is one of two sorcerers in the world classified as ‘Millennium Class’, meaning it would take a millennia to kill him. His bloodline is famed for pumping out powerhouse after powerhouse, yet he is the only one of his family to ever be classified as such. After training with masters of everything needed to be a unstoppable force in combat for a few years and ingesting power-up items from different worlds, universes, and realities, he has attained a truly supernatural physique. He is said to indisputably be the strongest sorcerer to ever live, along with Sapphire. His amount of cursed energy comes from two factors: being loved by the primordial forces and being in the main line of descent from the first sorcerer to exist.

**Supernatural Condition**: He possesses supernatural capabilities, attributes, and aspects that are drastically beyond what is naturally possible. With his condition alone, he can dwarf most beings, being virtually supreme in his existential aspects and attributes. With his truly superior constitution, he can move large aircraft and machinery, run at hypersonic speeds and beyond, survive powerful explosions unscathed, and remain active for days to weeks untired. With his mind, he can master languages and subjects in mere days or even hours.

**Master Hand-to-Hand Combatant**: Being trained by martial arts masters from parallel worlds, alternate realities, and fictional universes, he is without a doubt the best hand-to-hand combatant in the series. He has an intuitivel understanding of combat and an innate encyclopedic knowledge in hand-to-hand fighting styles, therefore understanding and analyzing opponents style of combat and flaws in their attack and defense. He can also use attacks that can automatically knock down his opponent or use the strength of his opponent to his favor.

He has an incredible perception of opponents and his surrounding areas, using them to his advantage. He is able to perform counters, techniques and combination strikes with such skill, speed, and prowess that far surpasses their regular counterparts. With his supernatural combative prowess, he is able to pull off hand-to-hand feats that are seemingly impossible for even the most skilled fighters that try to comprehend his foreign skill. He is also able to copy any and all actions after observing them performed once and contains involuntary reflexes. All these serve to make him a literal one-man army even without any cursed energy involved.

**Supernatural Strength:** Kieran's strength is truly unparalleled. He is capable of picking up locomotives and tearing the strongest metals like a piece of paper with his bare hands. He's able to send opponents flying several miles away with just a singular punch or kick and has even been shown to deflect a missile with his bare hand and remain unharmed.

**Supernatural Weapon Proficiency**: He is able to use anything at his disposal as a deadly weapon, be it a shoe or piece of paper. Although he may not be be familiar with certain weapons, he can wield them with such prowess that trumps even those who have dedicated their entire life to using the weapon. Even with something such as a toy knife, he is able to easily slice through steel.

**Great Tactical Intellect:** He is an extremely skilled strategic genius and is able to intuitively create strategies and plans several steps ahead of an opponent. This is not always shown in combat, but in games he frequently plays with his friends as well, e.g. beating Sapphire at Monopoly hundreds of times, being unstoppable at chess, always winning shooting games, etc. He can immediately deduce the best actions to take in any situation, allowing him to adapt and prepare for future events in advance by considering a large number of scenarios and plan ahead for them.

**Enhanced Beauty:** He possesses an inhuman level of physical beauty and social poise above humans, everything going above and beyond what they could dream of. He also has unnaturally high charisma, or charm, enabling him to gain the trust and loyalty of others and win them over to his cause. He has extreme charm and a 'magnetic' personality and appearance along with innate and powerfully sophisticated personal communicability and persuasiveness. His charisma is innately formed and effective for even the most disagreeable entities and allows them to bring the whole mobs of individuals to their aid.

### Jujutsu

**Immense Cursed Energy**: Kieran possesses a great amount of cursed energy thanks to the blood flowing through his veins, although he holds a bit more than his parents. Sapphire, a sorcerer with possibly the greatest amount of cursed energy to ever live, was quite alarmed by his distant presence and slightly frightened about the amount he contained. His cursed energy is described as incredibly fiery and “angry”.

 **Black Flash** (黒閃, *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 cursed power to flash black, creating a more potent attack to the power of 2.5 of a normal hit. He has performed this thrice in a row.

**Withering Wind** (木 (こ) 枯 (が) らし, *Kogarashi*?): Just like Sapphire, Kieran has a Binding Vow that restricts his cursed energy output to about 90%. Unlike Sapphire, however, he simply does it to not win his battles in one fell swoop. To break the vow, he must feel that he or others are in danger or Sapphire herself has broken her own vow. If Sapphire has, he is immediately teleported to her no matter where he is or what he’s doing, with his cursed energy reaching its full potential. After the danger has passed, the Vow is resumed.

**Oblivion** (オブリビオン, *Oburibion*?): Kieran’s Innate technique allows him complete and absolute manipulation over the fourth dimension; time. She can create, shape, move, control, interact and manipulate time, the indefinite continued progress of existence and events that occur in an apparently irreversible succession from the past, through the present, into the future, in the general area or for a specific target in various ways. From stopping time to even time traveling, she's able to perform all feats pertaining to time. It should be noted that, due to this being an innate technique, she has personally named all her moves.

**Time Energy** (時 (じ) 間 (かん) エネルギー, *Jikan enerugī*?): An extension technique that allows her to condense time into a quasi-tangible form and utilize it for more physical usage such as forming constructs and firing blasts. The fast currents of time energy can deflect attacks at amplified velocity and cause victims to disintegrate due to their physical body being unable to keep up with the flow of time. By constantly flowing it through her body, her cursed energy has fused with it. The only working constructs she's made with this are a road roller and road sign.

**ab aeterno**: Sapphire is able to manipulate the timestream, the very embodiment of time itself as a flowing body of water hidden in a dimension that only she can easily access. She's able to select the parts that will surely kill someone or at least irreparably damage them instead of the helpful sections that can do things such as heal or restore youth. To quickly access the dimension or summon water, she coats her forefingers with time energy and draws a triskelion in the air. Using it freely takes ample amounts of cursed energy that she does not have without breaking her Binding Vow.

**Stop** (止 (と) まれ, *Tomare*?): This technique allows Sapphire to completely freeze time, be it an area or certain objects. When freezing an area, she takes care to always resume the flow of photons, air molecules, and sound waves so she is not deaf or blind. She is the only one able to act during the duration of stopped time and can choose whether or not to reinstitute the time of other objects. All force applied by her during the time stop continues to exist after time moves once more. She can stop time indefinitely with no limit. Whenever using this, she always makes sure to chant the words: **The World, stop time!** (世 (ザ・ワ) 界 (ールド) ,時 (じ) よ止 (と) まれ) (*Za Wārudo, toki yo tomare*, *****The World, stop time!** (世 (ザ・ワ) 界 (ールド) ,時 (じ) よ止 (と) まれ)***?). This has endless possibilities, including but not limited to stopping time around a certain area around a target to render them blind, unable to breath, and deaf, stop someone's blood flow or organs, completely stop the movement of molecules to create absolute zero temperatures, stop something's movements, the progression of an injury or disease, etc.

**Fast-Forward** (早 (はや) 送 (おく) り, *Hayaokuri*?): Sapphire can accelerate time for herself or others up to practically light speed while still moving normally. She can also speed up the timeline of something or someone by taking it to the end of it's lifetime, speed up how quickly someone can process things and fry their brain, speeding an attack's time up to when it has already happened so it never really happens, speeding up molecules to generate heat, increase cellular activation to regenerate or give someone cancer, accelerate someone with so much speed and energy they spontaneously combust, etc.

**Rewind** (巻 (ま) き戻 (もど) し, *Maki modoshi*?): She is able to rewind the time of anything, and this is reflected in her eyes - the clock hands of her right eye rewind to however far she reversed time. If what she's affecting is something tangible, intricate clock markings appear on it and begin rewinding. If it's something abstract, a clock-like magic circle appears under where it *should* be. She can use this in a variety of ways, be it rewinding the healing process and bringing back old wounds or ailments, continuously rewinding back to when someone was not near her, reverse cursed energy back to its full reserves, a person's mentality back to when they were an infant, cells, objects, people, and attacks to when they did not exist, reverse the evolution process and have someone turn into a monkey, etc.

**Adomania** (アドマニア, *Adomania*?): After reading Part 5 of "Jojo's Bizarre Adventure", she became inspired and began perfecting this technique. She can choose any frame of time, be it 10 seconds or an hour, and erase and skip past it. She can choose to either remain conscious during this or not. When she does remain conscious, she is able to move about but cannot touch others trapped in the skipped time. They move as they would've if she hadn't skipped time and she chooses her movements by watching this. This specific period of time is erased from the timeline and Sapphire skips to when the actions committed in the duration of time have already ended. Others caught up in this are not aware of what has happened and can only gawk at the aftermath of the skipped time that still happened even though Sapphire erased the actions taken to the cause the effects via the power of fate. Simply put, she erases the "cause" and only the "effect" remains. An example would be someone throwing a punch at her and then somehow lying on the floor because Sapphire was fated to kick them in the skipped time. When using this, she never fails to shout: "**King Crimson!"** (キング・クリムゾン, *Kingu Kurimuzon*?)
