After bidding Ash farewell, Su Hao visited Mewtwo on Cero Island, then indulged in petting Solgaleo while reflecting on his Pokémon’s progress. The chapter leaves him reviewing his gains before his impending departure from this world.

• Su Hao asked Mewtwo where its adopted and cloned Pokémon were, and Mewtwo said they had been settled elsewhere until the renovations were complete.

• Su Hao noted that Milotic, Dragapult, and Hisuian Braviary had reached Champion Level, while Lucario showed promise of reaching it through the One-Hit Flow secret technique.

Su Hao reviewed the major gains he and his Pokémon had made in the other world and prepared to deliver a final attack on Ultra Megalopolis before returning to Blue Star. He reunited with Mewtwo, then left through an Ultra Wormhole with Solgaleo while Mewtwo stayed behind.

• Su Hao's Pokémon had grown stronger through new powers, moves, and guidance, while Su Hao had gained the Dynamax Band, Cresselia's power, and an Iron Plate Fragment.

• Su Hao said goodbye to Mewtwo and departed on Solgaleo, while Mewtwo stayed behind to handle its preparations.

Su Hao and Solgaleo entered a lifeless Ultra Space, where Su Hao realized they had reached a parallel world rather than the Ultra Forest. After sending Solgaleo back to protect it, he explored the wilderness and uncovered two Ultra Recon Squad suits belonging to Lisa and Blu.

• Solgaleo opened an Ultra Wormhole and carried Su Hao into a barren Ultra Space.
• Su Hao and Reshiram suspected the place was a parallel Ultra World, so Su Hao urged Solgaleo to return to its own world.
• After Solgaleo left, Su Hao summoned Metagross and explored the endless wilderness in search of life or a way out.
• Fourteen hours later, Su Hao detected something beneath rubble and had Metagross move it aside.
• Su Hao uncovered two Ultra Recon Squad protective suits and recognized them as Lisa and Blu's.

Su Hao found Sally and Blu dead in the wilderness and used Diancie to reactivate their damaged watches, hoping to learn how they had died. The surviving recordings suggested the Governing Elders' Council had kept them under questioning before they were sent on a mission that ended in a fatal suit malfunction and a collapse.

• Su Hao discovered Sally and Blu's bodies beneath rubble, buried them, and realized that less than half a month might have passed since he last saw them.
• Su Hao examined the two damaged watches and, with Reshiram's advice, decided to charge them with Diancie's Light Energy.
• Su Hao found that the watches had lost their communication functions and retained only damaged recordings, which he listened to while reviewing the surviving files.
• The recordings revealed that the Elders' Council had repeatedly questioned Sally and Blu about the other world and that the two had been kept in the metropolis for twelve days.
• The recordings showed Sally and Blu leaving on an Ultra Beast investigation mission after Lord Xion promised them leave, followed by a protective suit malfunction, a plea for help, and the sound of rubble crushing a body.

Su Hao concluded that Lisa and Blu had been killed after the Governing Elders' Council tampered with their protective suits, then continued exploring Ultra Space. He entered a new region filled with Poipole and Naganadel, where he encountered the master-level Naganadel from Shilin Town.

• Su Hao and Reshiram concluded that Lisa and Blu's protective suits had been sabotaged and suspected the Governing Elders' Council had arranged their deaths.

• Su Hao sensed an enormous colony in the new Ultra Space and flew toward a rocky mountain as a voice ordered its followers to welcome him.
• Poipole and Naganadel filled the sky and showed no hostility toward Su Hao.
• A massive Naganadel appeared before Su Hao, and he recognized it as the master-level Ultra Beast from Shilin Town.

Su Hao visited Naganadel’s nest and learned that Naganadel regarded Diancie as hope for the Ultra World. Naganadel then claimed that humans had harmed Necrozma and still controlled its body, revealing a different account of the Lightless Eternal Night Era.

• Naganadel welcomed Su Hao into its nest and offered to answer his questions after he agreed to let it meet Diancie.
• Su Hao brought out Diancie, whose Ultimate Burst illuminated the cavern and moved Naganadel to tears.
• Naganadel called Diancie the hope of the Ultra World, repeating what Lord Mewtwo had told it.
• Su Hao told Naganadel what Lisa and Blu had said about Necrozma’s fall and the Lightless Eternal Night Era.
• Naganadel rejected their account and accused greedy humans of harming Necrozma and keeping its body under their control.

Su Hao learned that humans had caused Luminous God Necrozma to fall, making Ultra Megalopolis a more dangerous enemy than he had expected. After Diancie brought light to the Naganadel clan, Naganadel entrusted a shiny Poipole to Su Hao.

• Naganadel told Su Hao that humans had harmed Necrozma and that its dwindling clan numbered only 251, prompting Su Hao and Reshiram to reconsider their plans against Ultra Megalopolis.
• Naganadel recounted how it had met Mewtwo, explained that Mewtwo traded supplies and captured aura energy for the clan’s venom, and suggested that Mewtwo opposed Ultra Megalopolis on someone else’s behalf.
• Su Hao agreed to let Diancie spread her radiant aura over part of the clan’s cavern, and the Poipole and Naganadel gathered to see the light.
• A shiny Poipole emerged from the clan, and Naganadel carefully presented it to Su Hao, asking him to take the child into his care.

Naganadel asked Su Hao to take its descendant, Poipole, to a brighter world, and Su Hao agreed and caught the lively Ultra Beast. The next day, Naganadel sensed Mewtwo approaching, while Metagross dreaded meeting it again.

• Naganadel asked Su Hao to take Poipole with him and explained that it had taught the youngster to open Ultra Wormholes.
• Poipole painted a picture of Su Hao and Diancie, delighting Diancie and helping Su Hao decide to accept it.

• The next day, Naganadel sensed Mewtwo approaching, and Metagross reacted with alarm at the prospect of seeing it again.

Mewtwo reunited with Su Hao after spending two and a half years reaching the parallel Ultra World, and agreed to return with him. After demonstrating its immense speed and trading remarks with the group, Mewtwo caught Metagross sneaking away and announced it would put it through special training.

• Mewtwo reached Su Hao in the Naganadel nest and told him it had spent two and a half years settling Pokémon, training, and searching for the parallel world's entrance.

• Mewtwo explained that Ultra Megalopolis's light-based surveillance, defenses, and mysterious tower made the city dangerous, while Su Hao shared what he had learned about the Governing Elders' Council and its plans for Blue Star.
• Su Hao agreed to visit Mewtwo's base and plan their revenge, and Naganadel asked him to notify it if an opportunity arose.
• Mewtwo opened a targeted Ultra Wormhole using a device powered by a captured Ultra Beast, and Su Hao followed it to Ultra Power Plant.
• Mewtwo led Su Hao through an abandoned power plant to its underground laboratory, where it kept Raging Bolt confined to generate electricity and open Ultra Wormholes.
• Su Hao recognized the room full of chemicals as Mewtwo's Toxin Laboratory.

Su Hao and Mewtwo planned to infiltrate Ultra Megalopolis, and Mewtwo began reverse-engineering Ultra Recon Squad watches to support the mission. Su Hao traveled through an Ultra Wormhole toward Blue Star, while the Divine Land Alliance continued searching for him and feared the world was nearing chaos.

• Mewtwo explained that its venom could not penetrate Ultra Megalopolis, so Su Hao proposed using the refugee camps outside the city to gather intelligence and infiltrate it.
• Mewtwo took Lisa and Blu's watches and recruited Metagross to help reverse-engineer their Light Energy technology within a week.
• Su Hao collected the laboratory's venoms for Poipole, left Light Energy for Mewtwo, and used the Ultra Wormhole switch to travel to Ultra Canyon.

• Mu Jianguo learned that a Master Level Ultra Wormhole had appeared and ordered Raikou and Elite Four members to prepare to respond.
• Miao Yin, Wang Anquan, Long Tianxing, and a military Elite Four Trainer gathered at the Hulunbuir Grassland camp to plan for the Ultra Beast’s arrival.

• Naganadel emerged from the Ultra Wormhole, and the monitoring team identified it as a Master Level Poison- and Dragon-type Ultra Beast.
• As Miao Yin prepared to call Raikou, Naganadel spoke into the four Trainers’ minds and asked if they were welcoming it.

Su Hao emerged from the Ultra Wormhole onto the Hulunbuir Grassland with Naganadel and Poipole, startling Miao Yin, Wang Anquan, Long Tianxing, and the military gathered there. After proving who he was and calming everyone, he learned that only half a month had passed on Blue Star, leaving him amazed at how powerful he had become in that short time.

• Su Hao arrived on Naganadel above a military command post, where Miao Yin, Wang Anquan, and Long Tianxing recognized his voice and reacted with alarm.
• Su Hao descended on Hisuian Braviary and greeted the group, then joked that a battle with Long Tianxing could prove he was really Su Hao.
• Long Tianxing protested that their grudges were settled and worried over the strength of Su Hao's Pokémon.
