Maki Zenin/Synopsis

History
Maki was born into the Zenin family as the daughter of Ogi Zenin and 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. However, the Zenin clan sought to stifle her efforts at every stage, going as far as to prevent her promotion from a Grade 4 sorcerer, despite her obvious talent.

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 Orimoto 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 ran to safety. After the incident, Maki started to train Yuta in melee combat. 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 Fushiguro and Nobara Kugisaki, questioning them why are they unhappy. From a far 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 to consider participating in 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.

Maki along with Toge and Panda, help train both Megumi and Nobara before the event, she then challenges Megumi so he can improve his close-range fighting capabilities. Later when Megumi talks with the others about how he should carry weapons without occupying his hands, Toge points out that Megumi manages to figure out a way with his shadow.

Later, when principal Yoshinobu Gakuganji came to Tokyo, Aoi Todo and Maki's twin sister, Mai Zenin were brought along as well. They provoked Megumi and Nobara, who were sent by Maki to do errands. While Megumi confronted 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, putting her in a chokehold. 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 Nobara's eagerness on the prospect of traveling to Kyoto. She and Panda also disparagingly commented about Satoru's habit of being late.

After Yuji was back with the students, the first and second years held a conference about the team battle. The second years 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 alone to prove her worth as a Jujutsu Sorcerer, to which Maki tells her that she won't hold back. As Maki takes on Miwa, Miwa notices that Maki is stronger then what she was led to believe by Maki's twin sister Mai. With Miwa struggling to counter Maki's assault, Maki easily distracts Miwa and manages to get close to Miwa and throws her 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 closes 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 with her bare hand and disarm Mai. A defeated Mai asks why Maki left their home, and Maki says that she already knows. Mai explains how she would be fine with serving the Zenin clan as a servant if Maki was with her, to 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 support 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 attacking since she senses they will be switching out. Suddenly Aoi and Yuji show up and rescue the two. Maki is then taken out of the site 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 and Aoi Todo for a promotion to a grade 1 sorcerer.

Shibuya Incident Arc
On October 31, Maki is with Naobito Zenin and Nobara at Shibuya Mark City Restaurant Avenue Entrance when they meet up with Akari Nitta. 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 Ijichi. 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 Kento 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, while 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, and Maki is instantly hit by the 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. After Naobito and Nanami are dealt with, Dagon attacks 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 the same way as the other two, which makes Maki think about how she should have gotten Playful Cloud from Megumi before coming here. Suddenly Megumi breaks into the territory and gives Maki the Playful Cloud cursed tool. Maki then uses the tool to fight Dagon and manages to wound it. Maki continues to fight Dagon with Naobito, but retreats when Megumi creates an exit. Maki makes it to the portal but is surprised when Toji Fushiguro comes through it.

Toji forcibly takes Playful Cloud from her, a feat that makes Maki wonder about the strength that Toji has. As Maki watches Toji fight against Dagon, Maki wonders aloud who Toji is, with Naobito responding that Toji is just a ghost. Maki is then shocked when Toji sharpens Playful Cloud, and brutally stabs Dagon repeatedly, exorcising him. Maki marvels 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. Yuta immediately asks if Maki is okay to be walking around, and Maki confirms that she's fine. Yuki explains that the reason behind why Maki is still alive is because of her physical toughness, although the burns scars will remain. Before Megumi is able to explain about Tengen's barrier, Choso steps in and does it himself. Choso explains about his connection 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, to which Yuji answers to think of him as his older brother. The group then enters the tombs to meet Master Tengen.

Yuki leads the group to where the main shrine is when Yuji comments on how there's nothing around. Just as the group gets ready to leave Master Tengen appears.

Maki is shocked upon seein Master Tengen for the first time. Tengen 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. Megumi and Yuta interrupt Tengen, asking about Kenjaku's objectives and how to free Gojo. Tengen says that they wished they could simply tell them everything right now, but says 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, saying it isn't fair because Tengen hasn't told them why and for how long they need to do it. Tengen explains how Kenjaku's objective is to force the evolution of all human beings throughout Japan by merging mankind with him. They add on that if humankind evolves and only one person rages out, the world will end, because there would be no boundaries between individuals, so evil would spread instantly. Maki asks why Tengen just refuses the merger, but Tengen says that is the problem.

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. Tengen tells the group that considering Kenjaku's ability as a sorcerer, Kenjaku might be able to seize absorb him. 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 to be the case.

When Yuki asks Tengen why all of this is happening now, they tell her that they, the Star Plasma Vessel, and the Six Eyes are all connected by fate. After having lost twice to a sorcerer with the Six Eyes in the past, Kenjaku had switched to sealing instead of 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. Then came a boy with curse manipulation and the unexpected happened: Toji Zenin's intervention. Tengen tells them that he was physically gifted through a heavenly restriction and was an anomaly who had zero cursed energy, and destroyed the path that was outlined for them by fate. Maki is shocked from learning this. That's when all the pieces suddenly came together, other than for the Prison Realm which fell into Kenjaku's 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. With that, Kenjaku will begin the merging of humans with Tengen. Tengen adds on that even if Kenjaku is killed, the culling game will continue until all participants are either dead or the players refuse to participate and die. 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.

Much to the surprise of both Yuji and Megumi, Yuki and Choso step up as guards for Tengen. Tengen thanks the group before pulling out a box that is the "back" of the Prison Realm. 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". 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. Unfortunately, both items were destroyed or thrown away by Gojo years ago. Tengen reveals that among the players participating in the culling game, there is a sorcerer from 1,000 years ago who calls herself 'Angel', and that her cursed technique can extinguish any cursed technique.

Maki listens to Tengen explain how there are 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. Tengen tells the group 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 and Tengen responds saying 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. He then turns to Master Tengen and says that they mentioned those who refuse to participate in the Culling Game will be killed. Tengen confirms this. 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, but Tengen says that they will be given a chance to exit. Yuta comments on how generous it is.

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. Tengen tells them that in order to confine the players, the premise that they entered of their free will is important. Tengen also 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 and says that they may think of the game master as the Culling Game itself. Choso asks if the seventh rule is fair which Maki confirms and adds on about how it gives the game master a lot of leeway.

Maki says that's all the information they need and that they all have a role to play now, 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 then turns to Master Tengen and asks about Juzo Kumiya's workshop.

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. He says that he'll immediately enter a colony to take part in the game and gather information. Megumi then turns to Maki, who tells them to group up with Kinji Hakari. Yuta tells a confused Yuji 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, and Yuta tells him that he's moody, but when Kinji is worked up he's stronger than him. Maki comments on how that's not true. Maki along with Megumi Fushiguro, Yuta Okkotsu and Yuji Itadori all leave the shrine.

Maki arrives at the Zenin household and is greeted by Naoya Zenin. He asks what she's going to do. Maki retorts that she's surprised Naoya can recognise women by their faces, because she thought he only looked at their asses. Naoya tells her to answer his question. He says no one will look in her direction anymore, since she can't see curses, can't use cursed techniques and her face, the only good thing about her, is now ruined by burns. He then asks her if he should bully her like he used to in the past, and an image of him standing on Maki's head comes to his mind. He asks her what she's going to do again, but Maki leaves.

On her way to the warehouse, Maki encounters her mother who tells her she must not enter. Maki then shows her the keys to the warehouse and says the head of the clan, Megumi, gave her permission. A flashback shows Maki and Megumi discussing whether Megumi should be the head of the Zenin clan. Megumi doesn't want to do it, but Maki insists. She tells him that they will gain money, cursed tools, and information if he's head of the clan and it will help them operate differently. When Megumi asks Maki to do it, she gets annoyed and tells him that no one would accept her. Unlike her, Megumi has an inherited technique, a domain expansion, and Satoru Gojo's favor. She adds that even becoming clan head wouldn't be able to make Mai feel like she belongs. This makes Megumi understand, and he accepts the position.

As Maki continues down the hallway her mother calls out to her and tells her to stop. When Maki ignores her, her mother tells her that she wishes Maki would make her proud of giving birth to her at least once. When Maki enters the warehouse she is greeted by her father Ogi Zenin, who tells her that he's already disposed of all the tools. Maki spots a wounded Mai behind her father and prepares to fight him. After a brief exchange of blows, Maki breaks Ogi's katana. Though to be defenseless, Maki attempted to deliver another blow. However, unknown to her, Ogi had recreated his blade with curse and slashed her flank. Maki was cofunsed, seeing that she had broke his sword. Ogi closes by stating that he wasn't family head because his children are worthless.

Ogi drags both of his beaten up daughters to the training room full of curse spirits and throws them in. He mocks Heavenly Restriction saying that sorcerers train daily to reinforce their bodies with curse energy and that Maki's strength is nothing special. He walks out of the room, calling him a stain on his life. Mai feels that Maki still has a heartbeat, seeing she's tough as usual. She suspected that this day would come.

Maki wakes up to a beach. Mai, sitting besides, her says that she should know how her curse technique works. Since she's heavily wounded, once she makes another object, she'll die. She walks into the ocean wishing her good luck and Maki interjects., calling her to come back. Mai says she knew that twins are auspicious for sorcerers. In order to gain something, one must sacrifice something, which is something other than a Binding Vow. In the same way, suffering make them stronger. This rule doesn't always apply to twins. Curse techniques treat twins as "one". Even with all of Maki's training, she won't fully develop since Mai doesn't strive to get stronger and has a curse technique while the former does not. Maki rushes towards her, saying she understand and asks her to come back. Mai says that she'll leave "this" and to "throw the rest away". Maki takes that item from her hand and Mai tells her to promise her one thing: destroy everything. Maki and Mai appear as their younger selves and then it return to the present where Maki is holding a sword in her hand. Mai lies unresponsive to Maki's pleas to awaken and the curse spirits begin to charge toward them.

Ogi feels a strange sensation emerging from the training room. He turns around and notices that all the curse spirits have vanished. He sees Maki and Mai at the doorway. He then feels an old sensation that he tried to forget: the fear of Toji Zen'in, which he sees in Maki. A frightened Ogi unleashed his innate technique Blazing Courage and means to burn her down with his own two hands. As he challenges her to fight, she quickly cuts his head horizontally in two, killing him. With her new sword, she tells Mai that they shall begin.
