• Academy City emerged from the earth as a giant, raising its head, arms, torso, and legs before the watching Fire Right Seat.

Mikoto brought Accelerator and Kamijou Touma into a shelter as Academy City attacked the Star of Bethlehem with Degenerate Engines, but Gabriel and flaming swords blocked the beams. Inside the transformed Academy City, Kuroko helped maintain order and confronted Mitsuya Aiyu.

• Mikoto explained that Academy City's 1.8 million residents had been transferred inside, while Touma had to remain outside because Imagine Breaker prevented his transfer.
• Academy City's Degenerate Engines fired three powerful beams at the Star of Bethlehem, but Gabriel and two enormous flaming swords stopped them.

• The footage shifted inside Academy City, where Kuroko and Uiharu discussed keeping order and dealing with hacker attacks in the transformed city.
• Kuroko reflected on Mikoto and Shokuhou Misaki's absence, then walked up to Mitsuya Aiyu.

Mitsuya Aiyu joined Shirai Kuroko in searching for Shokuhou Misaki, but Uiharu Kazari redirected them toward a threat to Academy City's core. At the Giant God Soldier, Nunotaba Shinobu revealed that Misaka Mikoto was inside Final Dogma, and Kuroko rushed to act.

• Hanazei Runko revealed that she and the others had seen through Mitsuya Aiyu's impersonation of Shokuhou Misaki, then encouraged her to go help the Queen.
• Shirai Kuroko contacted Uiharu Kazari, who sent them a route to investigate the Giant God Soldier and warned that someone was targeting its core.
• Mitsuya Aiyu decided to help protect Academy City, and she and Kuroko followed Uiharu's route to an observation area.
• Nunotaba Shinobu explained that the Giant God Soldier was firing powerful beams while an updraft dispersed the heat, and said that Misaka Mikoto was in Final Dogma.
• Shirai Kuroko cried out for Onee-sama, and the three began acting together.

Kuroko and Mitsuya learned that Misaka Mikoto was connected to the Final Dogma beneath Academy City, which outside espers were targeting alongside Arisa Meigo. As Academy City’s Giant God Soldier weakened the influence of the phases, the Roman Orthodox Church’s assault and a warning that the Science Side would destroy the world left the conflict’s outcome uncertain.

• Nunotaba Shinobu explained that the Final Dogma was the Giant God Soldier’s core and that the real Misaka Mikoto was there, while subordinate bodies could move outside.
• Mitsuya Aiyu concluded that the enemy likely sought to destroy the Final Dogma and assassinate Arisa Meigo, who could be targeted by the Apostle’s Cross.

Mikoto used Burning Style to direct Gabriel toward Endymion, where the Science Side’s Hyper-ranker appeared and fought the angel. Meanwhile, Kuroko and her companions tracked down Oriana Thomson, whose notepad let her cast dangerous magic, but they had not yet found a way to disarm her.

• Mikoto deployed Burning Style and sent Gabriel to attack Endymion, where the Hyper-ranker confronted the angel.
• Short-haired Mikoto, Shokuhou, and Dolly struggled to understand how the other Mikoto could use magic without being an Esper.
• Rear Water watched Gabriel and the Hyper-ranker clash, then spotted Roman Orthodox Church infiltrators in Academy City.
• Nunotaba Shinobu, Mitsuya Aiyu, and Kuroko located Oriana Thomson and pursued her through the city.
• Oriana used slips from her notepad to unleash air blades and fireballs, forcing Kuroko to evade and warn the others that Oriana could use multiple powers.

Shirai Kuroko and Nunotaba Shinobu realized Orianna’s apparent secret weapons were bait as another attacker reached Final Dogma with a dangerous cross. At the entrance, Arisa Meigo faced Lidovya Lorenjeti until Shatiora intervened, while the sealed door kept Arisa from entering.

• Shirai Kuroko attacked Orianna’s white-cloth-wrapped equipment, but Nunotaba Shinobu and Chunibyo Shirai discovered it seemed to be made of wood and suspected Orianna was a decoy.
• A second attacker reached Final Dogma and prepared to convert the site for the Roman Orthodox Church, while Arisa Meigo stood in her way and sensed danger from the cross-like weapon.

Meanwhile, Kamijou Touma, Accelerator, and Kamisato Kashiwazaki confronted Fire Right Seat aboard Star of Bethlehem, where he claimed he was restoring the world's order.

• Arisa Meigo transformed Academy City into a sterile environment, entered Final Dogma, and received Aiwass's offer of help as she set out to oppose Mikoto's approach.
• Short-haired Mikoto resolved to connect to the Misaka Network so she could expand her link to her counterpart and interfere with the other world.
• Accelerator and Kamijou Touma entered Star of Bethlehem to rescue Index, and Kamisato Kashiwazaki joined them after judging the Roman Orthodox Church's coup an unjust war.
• Kamisato Kashiwazaki explained that Star of Bethlehem foretold the birth of a savior, leading Kamijou Touma to realize Fire Right Seat intended to become one.
• Kamijou Touma, Accelerator, and Kamisato Kashiwazaki reached Fire Right Seat, who said he meant to restore the distorted elements of the world.

Kamijou Touma condemned Fire Right Seat’s claim to be saving the world, while Mikoto began rebuilding the world with the stars as its framework. At the entrance to Final Dogma, Shokuhou Misaki fought Elisa to stop her from reaching Mikoto.

• Kamijou Touma angrily rejected Fire Right Seat’s methods, and Kamisato Kashiwazaki searched for the hidden Index.
• Mikoto used the stars to restore the world’s structure and bring forth the Prime Mover.
• A man carrying a strange spear entered the passage to Final Dogma.
• Shokuhou Misaki confronted Elisa at the massive entrance and said she had to fulfill Mikoto’s wish.
• Shokuhou’s Mental Out failed against Arisa Meigo’s miraculous power, so she attacked her with Ultra Pure Water and charged forward.

Arisa Meigo sang to reach Mikoto and reject the world of happiness built on sacrifice while Aiwass fought Lanmoliwf. Meanwhile, Kamijou Touma discovered that the Fire Right Seat aboard the Star of Bethlehem was a fake, and the collapsing ship left him searching for a way out.

• Arisa Meigo opened the final gate and entered the pool as Mikoto and the angel resumed their song, spreading a peaceful paradise across the battlefield.

• Kamijou Touma grabbed Fire Right Seat aboard the Star of Bethlehem, but the figure disappeared as a fake, leaving Index’s location uncertain.
• Kamisato Kashiwazaki warned Kamijou Touma that the Star of Bethlehem was collapsing after the Giant God Soldier fired its beams.

As Kamijou Touma and Accelerator retreated while Kamisato Kashiwazaki gathered the nuns, Arisa Meigo struggled to reach Mikoto and deliver her feelings through a song. When they joined hands, Arisa saw memories of a girl whose world was fated to end and whose efforts to preserve her consciousness demanded ever greater sacrifice.

• Kamijou Touma, Accelerator, and Kamisato Kashiwazaki decided to retreat, with Kamisato taking the Roman Orthodox Church nuns and Kamijou taking Index.
• Short-haired Mikoto gathered the Misaka Sisters, Dolly, and Original Shokuhou to reach the other Mikoto.
• Arisa Meigo fought through the forces before Final Dogma and sang as she made her way toward Mikoto.
• Shokuhou Misaki gave Arisa her love, and Arisa used it to reach Mikoto and take her hands.
• Arisa saw a memory of a girl whose foreknowledge improved her life before her world was destroyed, and learned that preserving her consciousness required deeper integration and sacrifice.

Kamijou agreed to help harmonize the collapsing world by forging it a new driving force, with the Magic Gods’ power reduced and Dolly urging Mikoto to move forward.

• Shokuhou Misaki ran to Arisa Meigo, and Mikoto pulled Arisa aside before Fire Right Seat’s Longinus spear struck her in the chest.
• Fire Right Seat realized the spear had made him an ordinary Roman soldier rather than a savior, while Aleister revealed herself and observers recognized that Fire Right Seat had been manipulated.
• Kamijou Touma reached Index and confronted Fire Right Seat, then explained that Imagine Breaker harmonized rather than erased esper abilities.
• Short-haired Mikoto and an unknown presence explained that the world would eventually collapse without a driving force, and Kamijou proposed forging a new one from the world’s materials.
• The unknown presence warned that the Magic Gods would be weakened and cast down to the mortal realm, but Kamijou accepted the cost and offered his right hand.
• Dolly returned control of the body to Short-haired Mikoto and asked Onee-sama to move forward.

• Coronzon and Extra Individual combined their magic and technology to strike Final Dogma, giving Fire Right Seat an opening to throw Kamijou Touma toward Aleister.
• Kamijou Touma grabbed the Magic Gods’ power within Aleister, and Mikoto used the Misaka Network to help pull that power apart.

• Arisa Meigo and Shokuhou Misaki joined the Mikotos as they used the Magic Gods’ power to reshape and repair the world.
• Long-haired Mikoto warned that the reshaped world would deteriorate without someone maintaining it, and Arisa Meigo told her she could guide it.

Index’s hymn opened a path home as Arisa Meigo and Shokuhou helped Mikoto recover by sharing the burden of her power and repairing the world. As they prepared to finish correcting reality, the Magic God’s shadow shredded Kamijou Touma’s right hand.
