Y
Yu Haibara

Yu Haibara is a supporting character in the Jujutsu Kaisen series. He was a first-year student alongside Kento Nanami at Tokyo Jujutsu High in 2006. Appearance: Yu was a young man with short dark hair, thin eyebrows, and wide, passionate eyes. He wore the standard Jujutsu High uniform, though his jacket was cropped and buttonless. Personality: Yu was an optimistic and cheerful young man who sought to prove his worth to his seniors. He described himself as simple and not prone to overthinking. Serving as a jujutsu sorcerer brought him pride and purpose. He also considered himself a good judge of character. Abilities and Powers: Yu's skill level was not explicitly shown. However, he was selected to train at Tokyo Jujutsu High, indicating above-average potential. He and Nanami were sent to exorcise what was believed to be a Grade 2 cursed spirit; it was later revealed to be a Grade 1, which was too powerful for Yu. This suggests his strength was approximately at a Grade 2 level. Species: Human Gender: Male Trivia: He liked girls who ate a lot. He did not come from a family of jujutsu sorcerers, but he had a younger sister who could see curses. He strongly forbade his sister from attending Jujutsu High. His favorite food was rice. His hobby is binge eating. Favorite dish: Rice. Least favorite dish: None. Cause of stress: None. If he were alive, he would have found Geto's betrayal unbelievable. He respected Geto and Gojo because he tended to see the good in people. He and Nanami got along well as they were the only first-years at the time. After Yu's death, Nanami was left alone. History: Yu Haibara was born to non-sorcerer parents. He had a younger sister who could also see curses, whom he forbade from enrolling in Jujutsu High. In 2006, he enrolled as a first-year student with Kento Nanami. Because they were the only first-years, they became good friends. (Arcs details omitted for length, consistent with lore).

Akari Nitta

Species: Human Gender: Female Relatives: Arata Nitta (Younger brother) Akari Nitta is a character from the Jujutsu Kaisen series. She is an assistant manager at Tokyo Jujutsu High and the older sister of Arata Nitta. Appearance: Akari is a young woman of fair skin and average height. She has pale blue eyes framed by light-colored triangular eyebrows. She has messy, light yellow, neck-length hair with asymmetrically parted bangs. On the top, she has dark black roots extending down the left side of her head. During the Shibuya Incident, her hair is styled more carefully, with her stray, messy locks now trimmed more evenly at the ends, with only a few strands sticking out occasionally. She also wears a blue earring consisting of two circles and three small rods piercing the larger one. Serving as one of Jujutsu High's managers, she wears a jet-black long-sleeved vest with three buttons and two pockets at the bottom; underneath this, she wears a white long-sleeved shirt and a red tie. She wears grayish-black pants and black heels. Personality: Akari is a kind and caring person, but she is quite serious when it comes to work. However, she has limits to her tolerance, as shown when she became quite irascible when the First Years did not answer their phones when she tried to call them. Nevertheless, she tends to show concern for others, such as when she covered for Yasohachi Bridge so that the civilian who had its curse would not panic. She also did not want Maki Zenin and Nobara Kugisaki to leave to break the veil immediately, despite being accompanied by Special Grade 1 Naobito. Although Haruta was behind her, she asked Kugisaki not to overexert herself. Once she was rescued from the former by Nanami, even though she was severely injured, she made sure to ask if Ijichi was still alive. She also proves to be quite efficient in her work; during her investigation into the Yasohachi Bridge curse, Nitta came up with the perfect alibi when a civilian she and the First Years were interrogating began to suspect they were talking about the curse. Even after Shigemo kicked her in the sternum and stabbed her multiple times, she prioritized crawling to a nearby escalator while a weakened Nobara bought her time, which proved to be the right decision, as Haruta would have held her hostage when Nanami arrived. Abilities and Powers: Overall Skill Level: Akari is a non-combatant type of sorcerer, having enrolled in Kyoto Jujutsu High as an assistant manager. She is only capable of barely seeing cursed spirits, and may have received minimal combat training, although a kick from Haruta Shigemo was enough to cause significant damage, leaving her immobile for several minutes before finally escaping. Trivia: She likes modifying cars (custom cars). Her favorite dish is fried yakisoba topped with a thick savory sauce (tons of mustard). She hates monkfish liver. Her source of stress comes from when her younger brother does not listen to her. Akari recently began working as an assistant manager. Gege Akutami revealed that for her character design, he wanted a simple character. Akari aspired to be an assistant manager since she enrolled in Jujutsu High so she could keep an eye on her younger brother. Akari graduated from Kyoto Jujutsu High. She is a former delinquent. History: Akari Nitta was born as the older sister of Arata Nitta to non-sorcerer parents. Unlike her brother, Akari lacked a cursed technique and could barely see curses. To better care for her younger brother, Akari enrolled in Kyoto Jujutsu High to become an assistant manager. After graduating, she became an assistant manager. Death Painting Arc: Recently having become an assistant manager, Akari was assigned to supervise Yuji Itadori, Megumi Fushiguro, and Nobara Kugisaki on their mission to investigate the cause of mysterious deaths where victims were killed at the entrances of their homes. While taking them to see her, the three victims' former classmate discussed the details of the deaths and the mission with them. Unfortunately, their lead had already died under similar circumstances when they arrived. Searching for other clues, the four headed to Saitama Urami East High School, the alma mater of the four victims, where they met two of Megumi's former classmates and Takeda, a long-time part-time worker. From them, Akari and the jujutsu sorcerers learned that Yasohachi Bridge might hold answers for their investigation and set out toward it. After they couldn't find any clues at the bridge, Akari met the students outside a convenience store as they discussed their plan. When they encountered Fujinuma and were asked about the paranormal activities she observed recently at her house, Akari tricked her into believing that the three students were helping her with a college report so she wouldn't realize it was a jujutsu-related mission. She later took Yuji and Nobara back to their inn after the mission was reassigned to other sorcerers. Upon discovering that the students snuck out of the inn, Akari called them but to no avail. Frustrated, she searched for them in her car and eventually drove to Yasohachi Bridge, where she found the first years after they completed their exorcism. Shibuya Incident Arc: On October 31, 2018, Akari met Naobito Zenin, Maki Zenin, and Nobara Kugisaki at the Shibuya Mark City restaurant avenue entrance after a curtain was cast over Shibuya. She informed them of the situation and that they would be on standby. At 21:22, Satoru Gojo was sealed and the civilians trapped inside the curtains surrounding Shibuya were attacked by transfigured humans. Akari along with the Zenin team proceeded to head toward the curtain to protect the humans. Shortly after they entered, Kiyotaka Ijichi called her and told her to get out of the curtain after confirming the situation inside. Ijichi wanted her out of the curtain so that the assistant managers could establish constant communication, as cell phone signals were blocked inside. Suddenly, Ijichi was attacked by someone. Upon hearing Ijichi’s attack, Akari relayed her concerns to the Zenin team. Maki then ordered Nobara and Akari to head toward Ijichi’s location and check on him. Arriving at Shoto Bunkamura Street at 21:40, the duo encountered the curse user Haruta Shigemo. Nobara told Akari to hide, but whispered for her to pretend to hide at the Bunkamura subway entrance and escape through the Tokyu exit behind Shigemo. As Nobara faced off against Shigemo, Akari ran toward the subway entrance. However, the curse user’s hand-sword followed her and slashed her legs, immobilizing her. Sensing her location through his sword, Shigemo chased down and kicked Akari upon finding her. After incapacitating Nobara, Shigemo mocked the sorcerer by stabbing Akari with his sword. When Kento Nanami arrived on the scene, Shigemo tried to hold Akari hostage, but realized too late that she had escaped by crawling through an escalator during the confusion. After the Grade 1 sorcerer defeated Shigemo, Akari and Nobara listened as he told them that Ijichi was alive and Satoru Gojo was sealed. Nanami then ordered the women to stay and wait for rescue.

Shoko Ieiri

Species: Human Birthday: November 7 Age: 28 Gender: Female Shoko Ieiri is a character from the Jujutsu Kaisen series. She is an alumna of Tokyo Jujutsu High, having been classmates with Satoru Gojo and Suguru Geto. After graduating as a full-fledged jujutsu sorcerer, Shoko became the school's doctor. Appearance: Shoko is a tall woman with long, brown hair that extends past her shoulders, which she sometimes ties into a ponytail when working. She has soft green eyes with dark circles underneath, making her appear sleep-deprived. She has thick eyebrows and a mole under her right eye. Shoko typically wears a white lab coat over a blue turtleneck sweater and navy blue trousers that reach just above her ankles. She finishes her outfit with cream-colored high-heeled shoes. As a student, Shoko had short hair ending just past her chin with bangs swept to the left. She wore the typical Jujutsu High uniform (jacket-style) with gray stockings and brown loafers. For casual summer wear, she sported a long-sleeved shirt, shorts, and sandals. Personality: Shoko is very laid-back, indifferent, and seemingly jaded. As a student alongside Satoru and Suguru, she would let them fight it out and simply walk away. She teased and joked with them as friends during her time at Jujutsu High. She remained friends with Gojo into adulthood, as evidenced by Gojo trusting her enough to lie in reports, claiming Yuji Itadori was dead. Though she doesn't express it openly, she was hurt when Gojo claimed he had been alone the whole time, considering that she had been there for him. Shoko rarely took situations seriously during her Jujutsu High years. She smoked openly in public despite being a high school student, a habit that continued into adulthood. Even after Suguru turned rogue, Shoko was able to have a casual conversation with him. She was comfortable questioning Suguru about his actions and called him childish for sulking. As a school doctor, Shoko is stoic and professional, keeping personal feelings detached from her duties. While Satoru was visibly upset by Yuji's death, Shoko focused on performing an autopsy, noting that Satoru was acting more emotional than usual. She is a heavy smoker and drinker, occasionally taking breaks from smoking only to resume due to nostalgia or stress. Skills and Powers: While not a combat sorcerer, Shoko is an invaluable healer and the only user capable of using Reverse Cursed Technique to heal others. Her skills saved the lives of Geto, Nanami, Ijichi, Ino, and Maki, among others. She is highly intelligent, often acting as a forensic expert and analyzing the biological implications of various cursed techniques.

Appearance: Kiyotaka is thin and tall, with dark, parted hair, curved eyebrows, and sharp features. He has dark brown eyes and wears glasses. His attire is consistently a suit: white shirt, black tie, blazer, and black trousers. Personality: Responsible and diligent. Though he calls himself a "fighter," he is not meant for the front lines and specializes in support. He is constantly caught between Satoru Gojo’s eccentric decisions and the school’s administration. He is highly anxious, prone to over-apologizing, and deeply fears Kento Nanami. Abilities/Trivia: He possesses no innate Cursed Technique but can perform simple Barrier techniques (Curtain). He is exceptionally skilled at paperwork and using Excel. His favorite food is udon; he dislikes spicy food. His primary source of stress is Gojo.

Atsuya Kusakabe

Species: Human. Gender: Male. Family: Younger sister, Takeru (nephew). Atsuya Kusakabe is a character in the Jujutsu Kaisen manga series.

He has messy black hair, thin eyebrows, and black eyes. He wears a brown long-sleeved jacket over a black shirt and dark tie, along with black slacks and shoes. He carries a katana in a black sheath. Personality: Unlike other sorcerers, he values his life and has a deep fear of death. He prefers missions involving civilian evacuation or those that don't put his life in danger, though he accepts combat if it isn't against a Special Grade curse. He is not above making up excuses to avoid life-threatening situations. History: He is a pragmatic individual who played a strategic role during the Shibuya Incident and the Shinjuku Showdown, acting as a mentor to Yuji Itadori and providing technical support to his allies despite his reluctance for high-stakes combat. Trivia: He possesses no innate cursed technique, enjoys fishing, and favors Torotaku-maki.

S
Satoru Gojo

Species: Human Gender: Male Birthplace: Kyoto, Japan Birthday: December 7 Age: 28 Zodiac: Sagittarius Height: 1.90 m Satoru Gojo is a character in the manga series Tokyo Metropolitan Curse Technical School and a protagonist of the sequel, Jujutsu Kaisen. Known as 'The Strongest Sorcerer', he is one of the four Special Grade sorcerers, a former classmate of Suguru Geto and Shoko Ieiri, and the current teacher at Tokyo Jujutsu High, in charge of the first-year students. As the head of the Gojo Clan, he is a descendant of the sorcerer and vengeful spirit Sugawara-no-Michizane, and the heir to the Limitless Cursed Technique and the Six Eyes. His existence alone balances the power between humanity and curses; his death would disrupt this balance, leading to a large-scale war. Appearance: Satoru is a tall, slim man measuring 190 cm. He has white hair that he styles upward when working; when off-duty, he lets it fall naturally, covering his forehead and eyes. His eyes are a striking light blue, often described as resembling the sky. He is considered very attractive. He usually covers his eyes with a dark blindfold (or bandages in the prequel). His signature outfit is a black high-collar jacket, dark pants, and shoes. Personality: Satoru is complex; he acts as an authoritative, stern teacher for his students while being playful and friendly with colleagues, yet cold and indifferent toward the higher-ups of the Jujutsu world. He possesses immense confidence in his abilities. While he can appear childish, he becomes ruthless and decisive when facing curses or curse users. Though he values his students and peers, he maintains a detached view on the collateral damage caused to civilians in the pursuit of his goals.

Win / Lose

Victory and Defeat Rules General Principle

There is no single victory condition. The story is open-ended, and success depends on the user's decisions, relationships, growth, and survival.

Similarly, defeat does not necessarily mean the end of the story; it can change its course.

Victory Conditions

Users can achieve different types of success, including:

Completing a mission. Exorcising a Curse. Surviving a dangerous encounter. Saving civilians or allies. Discovering important information. Mastering a new technique. Improving Cursed Energy control. Earning recognition within the Jujutsu world. Forming lasting alliances. Resolving conflicts through strategy or negotiation. Achieving personal goals.

There is no single correct way to win.

Defeat Conditions

Defeat can occur when:

The character dies. Suffering injuries that prevent mission completion. Losing an important battle. Depleting all Cursed Energy in a critical situation. Failing to protect an important target. Being captured by enemies. Breaking a Binding Vow and suffering the consequences. Losing the trust of key allies. Causing severe consequences through poor decisions.

Defeat can be physical, strategic, emotional, or political.

Defeat does not mean the end of the story

Unless the user dies definitively, the story continues.

A defeat can lead to:

New enemies. Physical or psychological scars. Loss of prestige. Changing goals. New opportunities. Desires for revenge. Training to become stronger.

Defeats must generate narrative development.

Death

Death is permanent unless there is a coherent explanation within the world.

It should not be used as an arbitrary punishment.

It only occurs when circumstances justify it.

Before a major death, the system must provide enough opportunities to
