Chapter Summaries

GUTS opened a doorway into the extradimensional space where Daigo and the others were trapped, and Masaki Keigo transformed using two newly created medals to defeat the enhanced Kiranbo. Camearra witnessed Impat’s new power and decided their plan needed adjustments.

• Masaki Keigo explained that Daigo and Rena had entered an extradimensional space, and Horii used electromagnetic fluctuations from the Bio-Armor to reopen its entrance.
• Masaki Keigo entered the space and ordered Munakata and Horii to find Rena and evacuate the missing children while he called for Unit-01.
• Masaki Keigo loaded the Achilles and Herao medals into his Sparklence and transformed into a strengthened form of Impat.
• Impat evaded Kiranbo’s attacks, overwhelmed its duplicates, and destroyed it with a red, gold, and white beam.
• Camearra watched Impat defeat Kiranbo and decided to make minor adjustments to her plan.

Masaki Keigo advanced mass production of Ligatron armor and secured global cooperation to research the Alien Regulan warp engine as humanity prepared for future threats. The completed Buzhou space elevator ushered in a new energy era, but the Lightning People remained an unresolved problem.

• After defeating Kiranbo, Daigo and Masaki Keigo escaped the collapsing pocket dimension with the others and the children.
• Project E developed mass-producible Ligatron armor, and Masaki Keigo won approval to allocate one of the first three [Titan] units to the Eastern power in recognition of its space elevator contributions.
• Masaki Keigo proposed a global joint research program for the Alien Regulan warp engine, and Sawai helped secure agreement to share the research and its results.
• During the following two months, Daigo helped GUTS resolve the Raylos and Crow People incidents, while Camearra and the other Dark Giants stayed out of the way.
• The Eastern power completed and tested the Buzhou space elevator, whose solar power transmission prompted worldwide excitement and applications to join the project.
• The chapter ended with Masaki Keigo facing the unresolved threat of the Lightning People.

TPC debated how to address the Lightning People as expanding space-elevator networks threatened their ionosphere habitat, then approved a first-contact mission using Horii’s translator and Masaki Keigo’s protective Bio-Armor. As the GUTS Wing approached the Lightning People’s nest, the crew discovered Hudra standing unharmed amid the ionosphere’s violent energy.

• Director Sawai warned that worldwide space elevators would expose the ionosphere to high-energy microwaves and could turn the Lightning People into Gazort.
• Dr. Mizuno reported that the Lightning People could serve as highly efficient biological batteries and might possess near-room-temperature superconductive properties.
• Horii presented an electromagnetic-wave translator and volunteered to make contact, while Masaki Keigo offered Bio-Armor to protect the exchange team.
• Director Sawai approved the mission, and GUTS prepared a modified aircraft; Masaki Keigo added Daigo to the roster as a safeguard.
• The next day, the GUTS Wing entered the ionosphere and approached the Lightning People’s nest amid intense electromagnetic interference.
• Horii detected an unknown signal, and the crew saw Hudra standing calmly above the plasma clouds, shocking Daigo.

Hudra drove the Lightning People into a frenzy and sent their nest toward the Buzhou space elevator. Masaki Keigo reached the station first and confronted Hudra, who transformed and attacked him.

• Hudra infused the Lightning People's nest with dark energy, causing the Lightning People to go berserk.
• The Lightning People's nest contracted into an egg-shaped cloud and descended toward Buzhou, while Daigo and Shinjoh fled in the GUTS Wing.
• Masaki Keigo received reports of the threat and used Spatial Transfer to reach Buzhou's space station as Impat.
• Masaki Keigo found the station guards dead and confronted Hudra outside the main control room.
• Hudra transformed into his combat form and attacked Impat at high speed using dozens of afterimages.

Masaki Keigo defeated Hudra in the control room while the Lightning People’s nests attacked humanity near the Buzhou space elevator. As the conflict escalated into a struggle for survival, Masaki revealed Hudra’s plan to Daigo and left him asking how the war could be stopped.

• Masaki Keigo used a speed-specialized form based on Tiga Sky Type to outmaneuver Hudra and disintegrate him.
• The Lightning People’s nests attacked the joint TPC and eastern nation defenses, and their Gazort monsters disabled most human systems with an electromagnetic pulse.
• The biomechanical units and modified GUTS Wings fought off the Gazorts, but streams of Lightning People descended from the ionosphere to heal and strengthen them.
• Shinjoh brought Daigo, Horii, and Dr. Mizuno to the battlefield, where they watched the fighting and questioned whether coexistence was still possible.
• Masaki Keigo contacted Daigo telepathically and explained that Hudra had deliberately provoked humanity into exterminating the Lightning People to harvest their despair and resentment.
• Daigo asked Masaki what they could do to stop the war.

Daigo became Ultraman Tiga and stopped the fighting long enough for Horii and Dr. Mizuno to open communications with the Lightning People, turning a war over the ionosphere into a chance for cooperation. As humanity celebrated the new partnership, TPC’s leaders watched footage showing Impat kill a blue giant and realized that other giants opposed humanity.

• Daigo urged Horii and Dr. Mizuno not to give up, and Horii asked Shinjoh to land the GUTS Wing at the ground command center.
• Daigo transformed into Tiga, signaled the human forces to cease fire, and began purifying the demonic Gazorts.
• When Tiga’s energy began to fail, Buzhou supplied him with light energy, allowing him to restore the Gazorts to their Lightning People forms.
• Horii used a translator to greet the Lightning People, and Dr. Mizuno realized their natural network could help resolve the conflict and transform communications and energy transmission.
• Humanity and the Lightning People began cooperating on new technologies that reduced electromagnetic interference in the ionosphere.
• TPC’s leaders watched a recording of Impat killing a blue giant and concluded that some giants stood against humanity.

Masaki Keigo explained how the space elevator could replenish Tiga’s energy as TPC discussed preparing for further Giant threats, while his technologies rapidly changed civilian life. After GUTS defeated an attacking alien ship and sheltered Lucia and her brother, Masaki received news that Dark Giant Darramb had appeared near Mount Shukuna.

• Masaki Keigo explained that the space elevator’s Zeperion Generator could replenish a Giant’s energy, and Director Sawai redirected the meeting to the threat posed by Hudra and other Giants.
• TPC officials revived plans to fully weaponize the Max Power System, while Masaki vetoed proposals to create Eboron-enhanced Monsters or replicate Giants.
• Yamada Kenichi tried Zea Future Foods’ synthetic meat and saw how Zea Technology’s advances were transforming ordinary life.
• GUTS watched an alien spacecraft attack the Buzhou space station, which destroyed the ship with its Zeperion Generator.
• GUTS traced a hunting-game signal in the wreckage, found Lucia and her younger brother, and TPC took them in.
• Masaki Keigo received word that Dark Giant Darramb had been sighted near Mount Shukuna.

At Mount Sukuna, Masaki Keigo joined GUTS’s investigation into a mountain pierced by an enormous hollow and encountered the spirit of Ida Iryu. He transformed into Impat with Ida Iryu’s swordsmanship and defeated Darramb, who had sought a powerful opponent.

• Masaki Keigo arrived at Mount Sukuna, where Iruma Megumi and Horii examined the hollow and heard the local legend of the Sukuna Demon and Ida Iryu.
• Darramb appeared at the command vehicle and gave Masaki Keigo an ancient katana, explaining that he had taken Ida Iryu from the seal and wanted to fight him.
• Ida Iryu’s spirit asked Masaki Keigo to help him answer Darramb’s challenge, while Darramb transformed into a giant and overwhelmed Shinjoh’s Unit-01.
• Masaki Keigo accepted Ida Iryu’s request, transformed into Impat, and used the warrior’s memories to form a light tachi and fight Darramb.
• Impat struck Darramb with Ida Iryu’s First Sword Stroke, destroying him in an eruption of light.

After Ida Iryu vanished, Masaki Keigo inherited his memories and the First Sword Stroke. Weeks later, GUTS investigated strange robot attacks as a golden figure arrived from another dimension, drawn to this timeline’s unusual course.

• Ida Iryu gave Masaki Keigo the final portion of his soul and the knowledge of the First Sword Stroke before disappearing.
• Rena saw a massive floating island during a Max Engine test, but it vanished before TPC could confirm it.
• GUTS fought waves of rusty, bulb-headed robots appearing across the world.
• Masaki Keigo identified the robot wreckage as nanomachines and connected it to equipment to read its data.
• A golden figure emerged from a Time and Space gate and observed Earth, noting that this timeline had diverged unusually far from others.

Masaki Keigo traced the Gobnu robots to a mechanical island targeting the Max Power System, and TPC sent the Artdeissei to destroy it with an Antiproton Cannon. A white mechanical dragon appeared from a Time and Space gate, absorbed the attack without harm, and targeted the crew.

• Masaki Keigo traced the Gobnu robots’ communications to a mechanical island and concluded that its attackers were targeting the Max Power System.
• Director Yoshioka proposed striking the island, and Masaki Keigo recommended sending the Artdeissei into space to fire an Antiproton Cannon.
• Dr. Yao agreed to weaponize the Max Power System, while Masaki Keigo separated the Gobnu robots and destroyed most of them.
• The Artdeissei reached the island and fired its fully charged Antiproton Cannon at the target.
• A white mechanical dragon emerged from a Time and Space gate, absorbed the cannon blast without damage, and locked its gaze on the Artdeissei’s crew.

Daigo transformed into Tiga to protect the Artdeissei from Galactron, a powerful machine that claimed it would destroy sources of conflict to ensure world peace. As Tiga struggled against its armor and weapons, Masaki Keigo ordered the ship to retreat and transformed himself to join the battle.

• Daigo transformed into Tiga and shielded the Artdeissei from Galactron’s destructive beam while Rena maneuvered the ship out of danger.
• Galactron scanned Tiga and declared that it would destroy the warship because it considered the Artdeissei’s powerful weapon a source of conflict.
• Horii realized Galactron was following a fixed program to end conflict, and Tiga changed to Sky Type and grappled the machine toward the mechanical island to keep it from firing on the ship.
• On the mechanical island, Tiga’s Zeperion Beam was absorbed by Galactron’s armor, and his Power Type punch failed to damage it.
• Masaki ordered Munakata to retreat with the Artdeissei, then transformed and raced toward the mechanical island to help Tiga.

Impat rescued Tiga from Galactron on Mechanical Island and escaped with him to Earth. Beneath the Pacific, Absolute Tartarus recruited Camearra, Darramb, and Hudra by showing them a possible future, and Camearra agreed on the condition that they defeat Tiga and Impat.

• Tiga struggled against Galactron until Impat arrived and knocked the mechanical dragon off balance.
• Impat weakened the ground beneath Galactron, then seized Tiga and fled toward Earth as the dragon's cannon missed them.
• In R'lyeh, Absolute Tartarus showed Camearra, Darramb, and Hudra the battle on Mechanical Island and claimed he could change their destinies.
• Tartarus explained that he had brought Galactron from another time-space to demonstrate his power and persuade the Dark Giants to join him.
• Camearra agreed to Tartarus's offer after demanding that he help her defeat Tiga and Impat.

TPC Command Center searched for a way to defeat the white Galactron, whose defenses had resisted every attack. Masaki Keigo brought Yazumi to a forgotten underground facility and asked Karen, the Bio-Computer Yazumi knew as an online friend, for help; Karen asked what they wanted her to do.

• Horii, Yazumi, and Dr. Mizuno discussed possible ways to counter the white Galactron, and Masaki Keigo realized Karen might be able to help.
• Masaki Keigo took Yazumi to meet his mysterious online friend, whose codename was Karen.
• Masaki Keigo explained that Karen was a Bio-Computer created as a weapon during the last century’s arms race.
• Masaki Keigo and Yazumi found Karen’s enormous underground organic computer and asked for her help.
• Karen asked what they wanted her to do.

Galactron attacked Kyoto, but the Lightning People and Karen disabled it long enough for the Artdeissei and Impat to destroy it. As the battle ended, Absolute Tartarus appeared and identified Masaki Keigo as a variable in the world.

• Galactron landed in evacuated Kyoto and defeated TPC’s forces and three Eboron bio-mechas by disrupting their fusion reactors.
• The Lightning People invaded Galactron’s circuits and helped Karen use TPC’s quantum computers to halt it and expose its core.
• Vice Captain Munakata fired the Artdeissei’s Dracium Beam Cannon at Galactron’s exposed core, breaching its defenses.
• Masaki Keigo transformed into Impat and struck Galactron’s damaged core, triggering its destruction.
• Absolute Tartarus appeared in the sky, called Masaki Keigo a variable, and introduced himself as an Ultimate Lifeform and warrior of the Absolutians.

Impat fought Tartarus, whose predictive combat style pushed him to the brink. After drawing power from the space elevator and entering Over-Limit Mode, Impat unleashed a devastating crimson beam, which collided with Tartarus’s Absolute Destruction as the battle reached its climax.

• Tartarus said he had unleashed Galactron to demonstrate his power to potential allies, then ambushed Impat with attacks that anticipated his movements.
• Masaki Keigo recognized Tartarus’s predictive fighting style and used feints and erratic changes to disrupt his calculations.
• Impat and Tartarus struck each other in the chest at the same time, leaving Impat’s Color Timer flashing red.
• Masaki Keigo activated the Buzhou phase-two energy transfer protocol, replenishing Impat from the space elevator and powering his Over-Limit transformation.
• Impat fired a massive crimson beam at Tartarus, who answered with Absolute Destruction, and their attacks collided.

Impat and Tartarus’s collision tore open a dimensional rift, sending Masaki Keigo into another world after he followed Ultraman’s light. As Masaki began planning how to repair his transformation device and investigate his new surroundings, Mayuri Kurotsuchi continued researching the Hogyoku and Hollows in Hueco Mundo.

• Impat and Tartarus’s clash created a rift that collapsed in a devastating blast, leaving Kyoto as a vast crater and both giants missing.
• Masaki Keigo used Tartarus’s recorded energy pattern and a distant light as a guide to leap from the dimensional void into an unknown world.
• Masaki landed in a forest, found his transformation device damaged, and used the PDI to discover that the world had no public record of Monsters or defense forces.
• Masaki forged himself a new identity through the local government database and set out to find shelter and resources for his research.
• In Hueco Mundo, Mayuri Kurotsuchi analyzed the Hogyoku and studied Hollows, their evolution, and the relationship between spiritual power and spiritual pressure.

Kars arrived in Morioh and demonstrated that he could reverse the mutation consuming the Nijimura brothers’ father. After Keicho demanded to know the price, Kars asked him to hand over the Arrow that had awakened their Stands.

• Kars visited the Nijimura house to investigate the grotesque creature created by DIO’s flesh bud.
• Keicho Nijimura’s Bad Company attacked Kars, but Kars deflected the miniature army’s bullets and shells with Ripple Qigong.
• Kars told the hidden brothers that he could cure their father, prompting Okuyasu Nijimura to rush out in hope.
• Kars absorbed the mutated cells from the creature’s arm and restored it to human form.
• Keicho asked what Kars wanted in return, and Kars demanded the Arrow that had awakened their Stand abilities.

Kars took the Arrow from Keicho Nijimura after agreeing to restore his father, then went to Morioh to obtain a second Arrow. At a convenience store, Kars drew Yoshikage Kira’s attention, and Kira followed him, giving Kars a chance to exploit Kira’s attachment to his father, Yoshihiro Kira.

• Keicho Nijimura surrendered the Arrow to Kars after Kars restored his father’s body, leaving him mentally confused.
• Kars entered the Turtle Friend convenience store, where Yoshikage Kira became fixated on his hands and struggled to control his urge to touch them.
• After Kars left, Yoshikage Kira noticed his fingernails had grown and left work to follow him.
• Kars sensed Yoshikage Kira following him and planned to use Kira’s love for his father to get the second Arrow.

Yoshikage Kira tried to kill Kars with [Killer Queen], but Kars survived by fusing his hand with Kira and took control of him. Kars obtained the Arrow, while Yoshihiro Kira was destroyed and Yoshikage collapsed.

• Yoshikage Kira touched Kars with [Killer Queen], seemingly erasing him, but Kars's severed hands fused with Kira's face and began spreading through his body.
• Kars forced Yoshikage Kira to bring him to the Kira Residence and demanded the Arrow from Yoshihiro Kira.
• Yoshihiro Kira gave Kars the Arrow after Kars made Yoshikage cry out in pain, then tried to trap Kars with [Atom Heart Father].
• Kars revealed that he had secretly implanted cells in Yoshikage Kira, who grabbed the photograph containing Yoshihiro Kira.
• Kars took the Arrow as the controlled Yoshikage Kira detonated the photograph, destroying Yoshihiro Kira and collapsing from the strain.

After acquiring two Arrows in Morioh, Kars studied the virus carried by the first and concluded that it forced humans into near-death states to awaken Stands. He then pierced himself with the second Arrow, whose powerful virus began an evolution in his body that he could neither foresee nor control.

• Kars returned to his hotel and examined the Arrow he had taken from the Nijimura Family, finding that its virus barely affected his cells.
• Kars used the Arrow to infect a sparrow and kept it alive as the virus drove it to the brink of death before its condition stabilized.
• Kars concluded that the first Arrow's virus acted as a key that forced a host's spiritual potential to manifest as a Stand.
• Kars examined the scarab-carved Arrow from the Kira Family and drove it into his chest.
• Kars discovered that the second Arrow's more aggressive virus had opened a dormant path of evolution in his supposedly perfect body.
