Oboro and Saitama discussed the mysterious watcher and settled into dinner, while Sekingar learned Flashy Flash had lost his memories and Tatsumaki set out to confront Oboro. Tatsumaki arrived at their apartment, where Saitama mistook her for a lost child and Oboro pretended not to know her.

• Saitama told Oboro that the person watching him was human and said he wanted to meet the powerful stranger, while Oboro changed the subject.

• Tatsumaki angrily identified herself as the S-Class Rank 2 hero, but Oboro pretended not to know her.

Tatsumaki tried to attack Oboro and Saitama, but Saitama carried her outside and survived her escalating psychic assault. As she unleashed enough power to threaten Oboro’s apartment, Saitama grabbed her and sped away to protect his home.

Oboro ignored the House of Evolution's mosquito attack and the arrival of Genos, while Saitama dealt with the cyborg's pursuit and then defeated the House of Evolution's attackers. After Saitama and Genos left for the House of Evolution, Oboro decided to follow and observe Saitama's strength.

• Oboro sensed Mosquito Girl's outbreak in Z-City, shredded the mosquitoes in his room, and went back to sleep.
• A week later, Genos arrived at Saitama's apartment and insisted on becoming his disciple, while Oboro briefly greeted them and returned to his room.

• Oboro finished breakfast, considered the strength of Beast King and Asura Kabuto, and decided to go observe Saitama.

Oboro infiltrated the House of Evolution and examined Dr. Genus’s facilities before confronting Asura Kabuto in the underground prison. He left Kabuto behind as Saitama and Genos arrived to attack the base, and Genus headed toward the creature.

• Oboro entered the House of Evolution through a spatial passage and explored its laboratories, remaining unseen by the clones until he appeared on surveillance.
• Dr. Genus activated the base’s traps, unleashing monsters that killed clones, but they failed to stop Oboro.
• Oboro sensed Saitama and Genos arriving, vanished, and then reappeared in the underground prison where Asura Kabuto was bound among the corpses of Genus’s clones.
• Asura Kabuto attacked Oboro, but an invisible barrier blocked his punch, and Oboro called him unstable and a failure.
• Oboro warned Asura Kabuto that Genus was coming and that he would soon face a true new human, then escaped through another spatial passage.

Asura Kabuto confronted Saitama and Genos in the House of Evolution, but Saitama effortlessly stopped his Carnage Mode attack. When Asura mentioned the suited intruder, Saitama recognized Oboro hiding in a spatial rift and focused on learning what he looked like so he could seek revenge later.

• After Oboro left, Genus asked Asura to obtain a sample, and Asura agreed before carrying him through the walls to confront Saitama and Genos.
• Genos attacked Asura with his Machine Gun Blows and Flame Burst, but Asura was unharmed and Genus believed his creation could defeat Saitama.
• Saitama sent Asura flying with a look, described his three-year training routine, and then watched Asura activate Carnage Mode and seal the combat laboratory.
• Asura threatened to kill everyone, including the suited man who had escaped, and Saitama realized he meant Oboro hiding in a spatial rift.
• Asura struck at Saitama, who caught and crushed his fist before demanding a description of the suited intruder.

Saitama killed Asura Kabuto and tried to punch Oboro, who escaped through a spatial rift, leaving the House of Evolution and surrounding landscape devastated. Genos offered to investigate the suited man, but Saitama suddenly realized he was about to miss the supermarket sale.

• Asura Kabuto, terrified by Saitama, began describing the man in the black suit, but Oboro killed him before he could reveal more.
• Saitama launched himself at Oboro, whose spatial rift closed just before the punch could reach him.
• Saitama's punch blasted away the base's dome, nearby terrain, and clouds, while Genos briefly lost hearing and suffered a malfunction.

• Genos questioned the revived Dr. Genus about the suited man, but the doctor claimed not to know what he meant.
• Saitama realized it was Saturday and panicked because he was about to miss the supermarket sale.

After moving in with Saitama, Genos investigated the suited man who escaped the House of Evolution and became determined to meet Saitama’s neighbor, Oboro. During their visit, Genos scrutinized Oboro and suspected he was far from ordinary, while Oboro worried Genos might uncover his identity.

• Genos moved in with Saitama, cooked dinner, and reported that he had found no public information about the suited man who escaped.
• Genos reasoned that the suited man knew Saitama personally, while Saitama said he would stop him if he appeared again.
• Oboro overheard their conversation and decided to avoid wearing suits so Genos would be less likely to suspect him.
• The next day, Saitama brought Genos to visit Oboro, who welcomed them and accepted Genos’s formal greeting and gifts.
• Genos observed Oboro’s calm demeanor and comfortable home, then scanned him while wondering whether he was secretly powerful and well-connected.

Oboro recruited Dr. Genus into the Neo Heroes to organize its scientific research for his return to Hunter x Hunter. On his way home, he met Blue, Blast's son, who confronted him with the claim that he came from another universe.

• Blue told Oboro that he knew he had come from another universe, and Oboro smiled in response.

Oboro faced Blue, who accused him of stealing the Neo Heroes’ resources and attacked to drive him from the world. After effortlessly restraining Blue even when he unlocked his limiter, Oboro froze him in place, explained that Blue misunderstood the multiverse, and walked away, saying he was only borrowing the organization’s people.

• Blue confronted Oboro over gathering this world’s research and products, calling it theft and demanding that he return to his own world.
• Blue attacked Oboro with cyborg-enhanced speed and weapons, but Oboro caught his blows and evaded every assault without being injured.
• Blue stopped to unlock his limiter as Oboro warned that the Neo Heroes had already been infiltrated and that Blue could not fully control the organization.
• Oboro froze Blue in a space-time domain, told him that he and Blast could not perceive the true multiverse, and walked away after promising he was only borrowing Blue’s people.

After Oboro demonstrated his control over space, he reflected on its limits and settled into life alongside Saitama and Genos. When a massive meteorite threatened Z-City, Oboro judged that he could have stopped it while preventing the destruction caused by its fragments.

• After Oboro left, Blue wondered whether the dimensions he knew were real and whether Oboro knew his father.
• Oboro used his traversal ability to cross into an uninhabited area and considered how difficult it was to control time compared with space.
• Oboro watched news of Zeniru's attack and the capture of Hammerhead, then joined Saitama and Genos for dinner.
• A few days later, Oboro watched a giant meteorite fall toward Z-City and thought through how he could slow, dismantle, and redirect it.
• Oboro concluded that Saitama's destructive power was extraordinary after the meteorite disaster began.

After Saitama destroyed the meteor, the Hero Association took notice of him but publicly credited other heroes, while Oboro considered how humanity’s hopes might grant him power. The next morning, Sekingar visited Oboro to recruit him, warning that humanity faced an unimaginable disaster, and Oboro recognized it as Shibabawa’s prophecy.

• Saitama destroyed the meteor, but the Hero Association’s spokesperson credited several S-Class heroes and omitted him.
• Oboro reasoned that Saitama’s invincible strength might come from humanity’s need for a hero and wondered whether he could gain similar power through the wishes of Lake Island’s people.
• Sekingar arrived at Oboro’s home and asked him to join the Hero Association.
• Oboro refused, but Sekingar kowtowed and pleaded for Oboro to lend his strength to humanity because an unimaginable disaster was coming.
• Oboro identified the disaster as Shibabawa’s prophecy, astonishing Sekingar.

Sekingar tried to recruit Oboro after Shibabawa’s prophecy warned that Earth faced a God-level disaster, but Oboro refused and pointed him toward Saitama. Saitama and Genos decided to take the Hero Association exam, and Oboro agreed to join them after Saitama challenged him.

• Sekingar told Oboro about Shibabawa’s prophecy and asked him to join the Hero Association, but Oboro refused and warned that he could erase Sekingar’s memories.
• Oboro recommended Saitama as a powerful ally and reminded Sekingar that Blast might also help if Earth faced destruction.

• Saitama and Genos told Oboro they had decided to take the hero exam, and Genos encouraged Saitama to become a great hero.
• Saitama urged Oboro to take the exam too and suggested he was afraid of failing, prompting Oboro to agree.

Oboro joined Saitama and Genos for the Hero Association’s fifty-fifth evaluation, while the Association’s executives discussed Genos and Sekingar focused on Oboro. At the sixth venue, Oboro and Saitama both displayed overwhelming strength, turning the physical tests into a showcase for the two of them.

• Genos explained that the Association’s personal invitation suggested Oboro was exceptionally strong, and Saitama asked who Oboro was.
• Oboro, Saitama, and Genos set out to apply for the Hero Evaluation as Sekingar and the other executives discussed their applications.
• Sekingar believed Oboro was the strongest of the three and felt relieved that Oboro had agreed to become a hero.
• Two days later, Oboro, Saitama, and Genos arrived at the sixth evaluation venue and were assigned to separate examination rooms.
• Oboro broke records in the physical tests, while Saitama astonished the crowd by sending a shot put through the dome and damaging the ceiling.
• Oboro and Saitama impressed the participants with their performances, making the two halves of the venue their personal showcase.

After the hero exam, Oboro’s strength and secrets drew Saitama and Genos’s attention. When Genos showed Saitama incriminating videos of Oboro’s past money-making schemes, Oboro argued that Saitama was an accomplice and got him to agree to let the matter go.

• Oboro and Saitama finished the written exam, and Saitama questioned Oboro about his strength and his supposed enemies.
• Genos told Saitama that Dr. Kuseno had investigated Oboro and that he understood why the Hero Association had approached him.
• Genos showed Saitama videos of Oboro appearing naked and using his abilities to obtain money, despite Oboro telling him not to reveal his information.
• Saitama accused Oboro of criminal conduct and urged him to stop, but Oboro pointed out that Saitama had enjoyed the benefits of the money.
• Genos agreed that Saitama could be implicated, so Saitama backed down and said the past was past.

Oboro, Genos, and Saitama received their hero evaluation results, with Oboro and Genos rated S-Class and Saitama placed in C-Class. After the three attended the hero orientation, the Association’s executives debated whether Oboro should temporarily take Blast’s vacant first-place S-Class position.

• Oboro and Genos received S-Class ratings, while Saitama discovered he had scored 71 points and become a C-Class hero.
• Oboro teased Saitama about his rank, then led him and Genos to the Association’s hero orientation.
• Snake, an A-Class hero, berated Saitama during the orientation, but none of the three paid him much attention.
• Sekingar proposed temporarily placing Oboro at the top of the S-Class rankings while Blast remained away.
• The Association’s executives objected to Sekingar’s proposal, questioning Oboro’s record and the lack of evidence about his abilities.

Oboro became the eighteenth-ranked S-Class hero but refused to take on hero work, ignoring the Association’s efforts to recruit him and public demands that he act. As the Deep Sea King was defeated by Saitama, Oboro’s reputation collapsed, while he continued enjoying a quiet life at home.

• Sekingar showed the Association footage of Saitama and Oboro’s extraordinary physical tests, then told Oboro he had been ranked eighteenth among the S-Class heroes.
• Oboro told Sekingar he did not care about his rank and would rather be demoted to C-Class, then ended the call.
• The Association and the public investigated the new S-Class heroes, while Oboro stayed home and ignored monsters and calls for help.
• The Deep Sea King appeared in City J, and Saitama defeated him with one punch after the Association failed to reach Oboro.
• The public and Association condemned Oboro’s inaction, circulated embarrassing footage, and called him the “Heartless Hero,” while he ignored the backlash and enjoyed his ordinary life.

Oboro ate dinner with Saitama and Genos, who discussed the backlash against his S-Class hero status and his encounters with other heroes. Later, Oboro reflected on his longing to return to Hunter x Hunter and planned how he would prepare humanity to explore the Dark Continent.

• Saitama and Genos discussed the public protest against Oboro joining the Hero Association, while Genos noted that Oboro ranked first in online popularity.
• Genos told Oboro that Sweet Mask had warned him about his duties as an S-Class hero and would likely disapprove of Oboro’s attitude.
• Oboro thanked Genos for cleaning his room, then left Saitama’s home and walked through an uninhabited district.
• Oboro reflected that he missed Hunter x Hunter and believed he could now return there precisely.
• Oboro considered using resources and scientific research from other worlds to strengthen humanity before leading the first expedition into the Dark Continent.

Tatsumaki threatened Sekingar to learn Oboro’s location, while Sweet Mask confronted Oboro outside a supermarket and was overwhelmed by an illusion that revealed his monstrous form. Back at Oboro’s apartment, Genos found a black suit that made Saitama recall Oboro wearing it when he first moved in.
