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.

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.
