Maki Zenin/Synopsis

History
Maki was born into the Zenin family as the older twin sister of Mai Zenin. Due to her inability to see cursed spirits, Maki was often seen as the bravest of the two twins. Maki wanted to become stronger even with her inability to see cursed spirits, so she left the Zenin family in order to hone her skills, but only after declaring she will become the head of the family someday.

Cursed Child Arc
Maki, Toge Inumaki and Panda are seen talking about their incoming fourth classmate of the first year, Yuta Okkotsu. Yuta finally arrives and introduces himself to them, but Maki seems unimpressed with him and proceeds to berate him, causing Rika to attack her and the others. Later Maki is assigned with Yuta on a mission, but are attacked by a very powerful cursed spirits due to Suguru Geto's scheming. In great danger, Maki questioned Yuta for his purpose and encouraged him to use the power of Rika.

After that, Yuta held the injured children and Maki running to safe. Maki started to train Yuta for melee weapon after that. Panda mischievously tried to get the two together when he saw them started to get along well. Suguru Geto finally approached Yuta, insulted Maki and declared war at the college.

Right before war, Maki explained to Yuta about her lack of curse power and her motivation as a Sorcerer. Suguru then brutally wounds Maki to the point of death, and then injures Panda and Toge as well. Yuta then tried his best to heal them and manages to defeat Suguru. After the war, Yuta released the curse on Rika, finding him to be a very talented sorcerer, Yuta remained as a classmate with his friends.

Cursed Training Arc
A year later, Maki approaches first-years Megumi and Nobara, questioning them why are they unhappy. From afar distance, Panda whispers to her that their classmate Yuji Itadori recently died. This shocks Maki, causing her to lash out at Panda and Toge for not telling her earlier.

Regardless of that, she requests the first-years about going to the Kyoto Goodwill Event, explaining the overall structure of the event to them. Motivated to become stronger for the sake of their fallen friend, Megumi and Nobara accept Maki's request to join the Kyoto Goodwill Event.

Later, when principal Gakuganji came to Tokyo, Aoi Todo and Maki's twin sister, Mai Zenin were brought along as well. They provoked Megumi and Nobara, which were sent by Maki to do errands. While Megumi confronted with Aoi Todo, Mai started to attack Nobara. The second-years manage to intervene these fights. Mai and Maki mock each other for both their lack of talent. As Maki continues to provoke Mai, this allows Nobara to sneak attack the latter. Afterwards, Maki explains to Nobara about her family situation. Nobara then grows to admire Maki for remaining strong even though the latter's family had disowned her.

Kyoto Goodwill Event Arc
When the team from Kyoto Jujutsu High arrives, Maki teased about Nobara's eagerness of travelling to Kyoto. She and Panda also commented about Satoru's habit of being late.

After Yuji was back with the students, the first and second graders held a conference about the team battle. The second graders asked about the skills of Yuji, and Maki asked him to confront with Aoi Todo.

When the event starts, Maki travels with the other Tokyo students. When they encounter Aoi, Maki splits from the group with Megumi. After splitting up, Maki talks with the others about how the Kyoto students are trying to kill Yuji. Maki and Megumi then head back and encounter Noritoshi Kamo and Kasumi Miwa. Maki takes on Miwa, but asks why Miwa wants to fight alone. Miwa tells her why she wants to take on Maki allow, which Maki tells her that she won't hold back. As Maki takes on Miwa, Miwa notices that Maki is stronger then want she was told by Maki's twin sister Mai. When Miwa trying to counter Maki's assault, Maki easily distracts Miwa and manages to get close to Miwa. Maki throws Miwa off, while also taking her sword. Maki then leaves while taking Miwa's sword with her.

Maki encounters her sister Mai, and the two start to fight. Maki easily counters all of Mai's shots and close the distance between the two. Once Mai fires all six shots from her revolver, Maki charges at Mai. Maki plans to make sure that Mai can't reload, but is shocked when Mai fires a seventh shot. Maki manages to catch the bullet and win against Mai. Mai asks why Maki left, which Maki says that she already knows. Mai explains how she would be fine to serve the Zenin clan as a servant if Maki was with her, which Maki replies that she would have hated herself if she did that. Maki then apologizes to Mai and leaves.

When intruders invade the site of the event, Maki notices that a screen is being placed over the site they are at. Maki then takes on Hanami along with Megumi, after Toge and Noritoshi are defeated. Maki takes on Hanami with Playful Cloud and manages to send Hanami flying.

Maki continues to attack Hanami with Megumi's assistant but is forced to fight Hanami alone when Hanami places a cursed energy feeding seed onto Megumi. When Hanami manages to catch Maki, Maki stops Megumi from attack since they will be switching out. Suddenly Aoi and Yuji show up and rescue the two. Maki is then taken out of the screen along with Megumi, by Panda.

After the intruders have been dealt with, Maki attends a meeting where they all agree with continuing the event. Maki then play a game of baseball with the others, where she pitches for her team. When Aoi is up to bat, Maki beans him and is complimented for it.

Death Painting Arc
After the Kyoto Goodwill Event, Maki is nominated by Mei Mei for a promotion to a grade 1 sorcerer.

Shibuya Incident Arc
On October 31, Maki is with Noabito and Nobara at Shibuya Mark City Restaurant Avenue Entrance when they meet up with Akari. Maki then listens as Akari informs them about the situation and how they will be on standby for now. Later when the citizens are attacked by mutated humans, Maki along with Nobara and Naobito head into the curtain to save the people. While dealing with the mutated humans, Maki is informed that something has happened to Kiyotaka. Maki thinks about how something feels off, and tells Nobara to take Akari to Kiyotaka's location since the assistance directors are critical and that she will deal with the mutated humans.

Maki and Naobito would meet up with Nanami, and then three head to the Shibuya Station. Along the way, Naobito tries to get Maki to leave, but Maki turns the table and says that Naobito has been drinking. When the three encounter a cursed spirit, Maki watches as Naobito takes on the spirit. When the cursed spirit, Dagon, releases a torrent of water, Maki manages to get above the water and thinks about how she would have been a goner if she didn't save herself. After Naobito manages to distract Dagon, Maki and Nanami join in the fight. Dagon manages to defend itself from the three, which Maki thinks about how humiliating it was to be saved by Naobito during the clash. When Naobito comments about how Dagon is defending itself, Maki joins in as the three overwhelm Dagon with speed based attacks and force Dagon to retreat.

Maki along with Naobito and Nanami are suddenly trapped within Dagon's Domain Expansion, which Maki is instantly hit by Dagon Domain's sure-hit technique. After figuring out what to do with each, Dagon uses his Death Swarm attack which Nanami advises Maki on how to survive the attack. After Naobito and Nanami are dealt with, Dagon attack Maki while calling her weak. Maki quickly returns and tells Dagon that he should have killed her with one attack if he is calling her weak. Dagon says that he will deal with Maki that same as the other two, which Maki thinks about how she should have gotten Roaming Cloud from Megumi before coming here. Suddenly Megumi breaks into the territory and gives Maki the Roaming Cloud cursed tool. Maki then uses the tool to fight Dagon and manages to wound it. Maki continues to fight Dagon with Naobito, but retreat when Megumi creates an exit. Maki makes it to the portal but is surprised when Toji comes through it.

Toji takes Roaming Cloud from her, which Maki wonders about the strength that Toji has. As Maki watches Toji fight against Dagon, Maki wonder just who Toji is which Naobito says that Toji is just a ghost. Maki is then shocked when Toji sharpens Roaming Cloud. When Toji exorcises Dagon, Maki thinks about how Toji was able to take care of Dagon by himself.

Distracted by Toji suddenly grabbing Megumi and fleeing through a window, she fails to notice the arrival of Jogo, who mourns his fallen comrade. Maki watches as the vengeful spirit turns to them, effortlessly advancing on Nanami and engulfing him in a blast of fire from his palm. Before she can even finish calling out for Nanami, Jogo moves towards Maki and immolates her from the chest up with a flick of the wrist, causing her to fall unconscious.

Itadori's Extermination Arc
Maki is eventually rescued after the events in Shibuya, but is in critical condition according to the Zenin Family.

Culling Game Arc
Maki is with Yuki Tsukumo at Tokyo Jujutsu High when Yuji, Megumi, Choso, and Yuta all walk in. Maki unenthusiastically greets them says long time no see. Yuta immediately asks if Maki is okay to be walking around who confirms. Yuki says that the reason behind why Maki is still alive is because of her physical toughness although the burns scars will remain. Choso explains about his connected to the rest of the Death Painting Wombs and how he should be able to provide some guidance. Maki says that's fine before asking who Choso is who says just to think of him as his big brother. When Yuji and Choso push a door open which leads to where the rest of the Death Painting Wombs and Master Tengen residing in is pushed open, Yuki tells the group that there's an elevator that leads down to where Tengen is. When Yuji wonders about the blood stains and what happened there, Yuki tells the group that it happened 11 years ago where everything started disorienting. This leaves both Yuta and Maki confused.

Yuki leads the group to where the main shrine is when Yuji comments on how there's nothing around. Yuta says that Tsumiki doesn't have enough time and tells the group to leave just as Master Tengen appears, asking why they're leaving so soon before greeting the group.

Maki immediately recognizes Master Tengen as Yuki asks them why they closed off the Tomb of the Star Corridor where they reveal that they were afraid they were aligned with Kenjaku. Confused of who Kenjaku is, Yuki wonders who they are where Tengen reveals that they were the sorcerer who once was Noritoshi Kamo but now has inhabited Suguru Geto's body. Yuji suddenly interrupts the conversation asking why Master Tengen looks the way they look who says that they are immortal but is not immune to aging and that is the reason why they look the way they are. Tengen tells him that in 500 years he'll look like this as well where Yuji is surprised by this. They tell the group that 11 years ago when they failed to merge with a Star Plasma Vessel, their aging accelerated and their self awareness as an individual diminished and that the world became themselves. When Megumi and Yuta interrupts Tengen, asking about Kenjaku's objectives and how to free Gojo. Yuji listens as Tengen says that they wished they could've simply said yes but they will need either Yuki Tsukumo, Yuta Okkotsu or Choso to remain as their two guards. Yuta wonders why they need guards even though they're immortal while Maki asks if they're worried about the seal.

Yuki objects to this says it isn't fair because they haven't told them why and for how long they need to do it. Tengen explains about how Kenjaku's objective is to force the evolution of all human beings throughout Japan. While Tengen is explaining about how Kenjaku lacks the cursed energy to do so. When Tengen reveals that the method Kenjaku has chosen is to merge humankind with themselves. Yuji is shocked by this and asks if it's even possible, where Tengen confirms. They explains that they possess barrier techniques which enable them to maintain their current form and self control even after evolving. They add on that if humankind evolves and only one person rages out, the world will end. Yuki asks them why who says that the impurities of a hundred million people would flood the world, which what happened to Tokyo would happen to the entire world as well. They add that there are no boundaries between individuals so evil would spread instantly. Maki asks why they don't refuse to merge, Tengen says that is the problem. Yuji asks Tengen why Kenjaku would do this who is unsure why because they cannot read human hearts.

Tengen tells the group that now that they've evolved, they are more cursed spirit than human which makes them a target for cursed spirit manipulation, shocking everyone. While Tengen is explaining everything, Yuji listens to them as Tengen tells the group that considering Kenjaku's ability as a sorcerer, he might be able to seize themselves if they encounter each other. They add that this is the reason why their main body is rejecting everything at the Tombs of the Star Corridor. Yuta wonders if that's the reason why they want guards which they confirm. They tell them that Kenjaku is the second most powerful barrier user behind themselves where Yuki asks them why now of all times. She adds on that he prevented a merging with a Star Plasma Vessel, forced their evolution and also wants to consume and control them through cursed spirit manipulation. She adds on that he was apparently involved with Sukuna and has been a sorcerer for at least 1,000 years. Tengen tells her that themselves, the Star Plasma Vessel and the Six Eyes are all connected by faith.

Tengen reveal that Kenjaku lost twice to a sorcerer with the Six Eyes and the second time he took no chances and killed both the Star Plasma Vessel and the Six Eyes less than a month after they were born. On the day of the merging, both the Six Eyes and the Star Plasma Vessel appeared. Which Kenjaku switched to sealing instead eradicating the Six Eyes and thus began searching for the Prison Realm because two bearers of the Six Eyes cannot appear at the same time. However, the unexpected happened 11 years ago when Toji Zenin intervened. Tengen tells them that he was physically gifted through a Heavenly Restriction and was an anomaly who had zero cursed energy and destroyed their destiny. Maki is shocked from learning of this. Then came a boy with curse manipulation, where all the pieces suddenly came together other than for the Prison Realm which fell into his grasp six years ago.

When Megumi asks why the culling game is happening, Tengen explains the culling game uses the participants and the boundaries binding barriers in a ritual that conveys to the human beings of this country to the other side. And with that, Kenjaku will begin the merging with themselves, however, to preform the ritual, he has undertaken certain binding vows. They add on that one stipulates that he isn't the game master and this game doesn't work in their favor because even if Kenjaku is killed, the culling game will continue until all participants are either dead or the players refuse to participate and die. Yuji notices that Megumi is upset by this but is unsure why. Yuta concludes that they have no other choice but to participate and add a rule that allows Tsumiki and other unwilling participants to safely get out. Megumi adds that they also should free Gojo sensei because he would be able to settle everything on his own. Yuji looks over at Master Tengen and asks for them to tell them but they say to first decide who should remain as guards.

Much to the surprise of both Yuji and Megumi, Yuki and Choso step up for that position. Choso tells Yuji he will absolutely need either Okkotsu or Yuki's cooperation especially if Kenjaku comes for Tengen. Tengen thanks the group before pulling out a box that is the "back" of the Prison Realm. Tengen explains that before Kenjaku found the Prison Realm, it was outside of their barrier who believes it was overseas and reveals that by sealing the rear gate, they were hiding the existence of the "front" but it was useless. Yuji asks if it's like a back gate which Tengen confirms it is. Tengen tells them that Gojo is sealed inside of the rear gate as well and that the authority of opening the gate rests with Kenjaku as he is the bearer point of the "front". They add on that to break it open, they will need the Inverted Spear of Heaven that nullifies cursed techniques and or the Black Rope that disrupts and cancels cursed techniques effects.

Yuji and Megumi are shocked because Gojo either sealed and or destroyed it 11 years ago but Yuta tells them that he along with Miguel searched for it in Africa but to no avail. Yuki asks Tengen if there's a way who confirms there is. Tengen reveals that among the players participating in the culling game, there is a sorcerer from 1,000 years ago who calls herself, an angel and that her cursed technique can extinguish any cursed technique.

Maki is present when Megumi asks Master Tengen if they're aware of where Hana Kurusu is who says that she's in the colony east of Tokyo. Maki listens to Tengen explain how there 10 colonies around Japan that are all connected by a barrier that forms a line that sends humans from Japan to the other side. Yuki asks if the reason why Hokkaido isn't included because of jujutsu society's barriers which Tengen confirms before adding on that Hokkaido is established as vast sacred land with Yuji commenting on how that's rugged lands. Tengen tells them that conveyance to the other side may sound like an exaggeration but a curse fell on everyone in Japan in preparation of the merger. Megumi asks how long will it take to complete the ritual where they say it will most likely take 2 months.

Maki says that it's currently 9 a.m. on November 9th, Yuta adds on that the sorcerer players awakened at about midnight on October 31st. Megumi comes to the conclusion that Tsumiki only has 10 days and 15 hours to declare her participation who then turns to Master Tengen and says that they mentioned those who refuse to participate in the Culling Game will be killed who confirms. Maki includes how Shoko was correct about the cursed technique removal and also adds on that sorcerers without a cursed technique such as herself aren't at risk. She wonders if Panda is fine and wonders if he even has a brain. Yuji wonders about the civilians who's already inside a barrier where Tengen says that they will be given a chance to exit much to his surprise. Yuta comments on how generous of it of them.

Tengen says that there is no rule about entering or exiting colonies and adds on that from the start, players are given a clear objective of exiting the barrier and that they suppose this is for stimulating the game. Tengen tells them that in order to confine the players, the premise that they entered of their free will is important. Yuji thinks about what Ino told him about the "increase or decrease" of a barriers effectiveness. Tengen tells them that each player will receive a shikigami that's called a Kogane. Tengen adds that a Kogane is less game master than an interface. They say that they may think of the game master as the Culling Game programmer which confuses Yuji. Yuji says that they're unable to subtract rules that have already exist while Megumi says that there are ways to counteract the rules. Choso asks if the sixth rule is fair which Maki confirms and adds on about how it gives the game master a lot of leeway.

Tengen informs them that the players are subjected to strict rules and sorcery wise, Kenjaku is due to no further bias. Yuji is disappointed that he will be forced to kill people again as Megumi tells him that he has a few ideas. Maki tells them that's all the information they have obtained and now they all have a role to play with Yuki and Choso remaining as Master Tengen's guards. Maki says that she'll return to the Zenin family and collect cursed tools. She reveals that soon after Satoru Gojo was sealed, the Kamo and Zenin family went to Tokyo Jujutsu High's cursed warehouse and completely emptied it, Maki also includes that Megumi is now the current Zenin family leader much to Yuji's surprise. Maki adds on that thanks to Megumi being the new family leader, it's possible to search the Zenin family's warehouse at length. She turns to Master Tengen and asks about Juzo Kumiya's warehouse.

Maki says that afterwards, she will go look for Panda and help him address the game before turning to Yuta and asking what he'll do who says that he'll enter a colony immediately to take part in the game and adds that before Tsumiki and the others participate, he wants to gather information and will avoid nearby colonies to avoid killing each other. Yuta also adds on that the barriers may block phone reception so they may be out of touch for a while before realizing that if Sukuna were to ever take over, it would be dangerous for Megumi. Megumi assures Yuji that it won't happen who is angered by him and says that if it ever did come to that conclusion and he dies, Megumi tells Yuji to just ask Yuta to kill him.

Megumi then turns to Maki who tells them to group up with Kinji Hakari where Yuji is confused by who they are as Yuta tells him that Kinji is a suspended third-year. Maki tells them that because they're shorthanded at the moment, they will need to rope in as many people as they can. Yuji asks if Kinji is tough where Yuta tells him that he's moody but when Kinji is worked up, he's stronger than himself as Maki comments on how that's not true. Maki along with Megumi Fushiguro, Yuta Okkotsu and Yuji Itadori all leaves the shrine.
