Sometime later, Best Jeanist attends a meeting at the police station with several of the heroes who had participated in suppressing the outbreak, like Eraser Head, Endeavor, Midnight, Ingenium and many more. Once in the meeting room, Detective Eizo Tanuma informs them that the Instant Villains they had defeated are unwilling civilians who were injected with Trigger by someone.

When the meeting ends, and Best Jeanist is about to leave to return to his duties, the police station is attacked by the Suicide Bomber. Best Jeanist and other heroes prepare to defeat him before he hurts someone, but the villain is quickly defeated by Midnight and Eraser Head.

During the event, he uses his Fiber Master Quirk to entertain the audience by decking various heroines with dresses.

However, the event is interrupted when the the Tokyo Sky Egg is attacked by creatures known as Bombers sent by the villain, Number 6. The villain wants to kill Captain Celebrity, and for this he planned the attack carefully. He orders one of his bombers to self-destruct to seriously damage the building, forcing Captain Celebrity to hold it to prevent its collapse, but leaving him defenseless against the attack of the creatures.. He also makes another creature cut off communications with the outside.

In one of the rooms of the Sky Egg, the heroes and show staff discuss the situation. Best Jeanist deduces that everything that is happening is the result of a meticulous plan that seeks to seal them all in the building. He decides that the best option is for the show staff and a group of heroes to look after the civilians without telling them the truth about what is happening to avoid panic. Meanwhile, another group will go outside to face the creatures.

Thanks to Koichi protecting Captain Celebrity, the heroes manage to arrive in time to help. With the help of Edgeshot, Best Jeanist manages to capture the last bomber with his Fiber Master Quirk. After this, he asks Ingenium if what he requested had arrived, and then he is informed of the arrival of a truck transporting carbon fiber cables made for suspension bridges. Best Jeanist descends to the ground and uses his Quirk to manipulate the cables and secure the structure, preventing the Tokyo Sky Egg dome from falling.

In the distance, Number 6 sees that his plan is about to fail because of the heroes so, in retaliation, he orders the last Bomber to self-destruct. The Bomber frees itself form the fibers and explodes causing the building to begin to crumble. Fortunately, All Might arrives in time and manages save everybody's life.

Later, while speaking to the media, Best Jeanist praises both All Might and Captain Celebrity for helping save thousands of lives during the terrorist attack.

Naruhata Lockdown Arc
Best Jeanist is called to apprehend Koichi Haimawari, the vigilante known as The Crawler, by the police following an attack on the police department by an unknown assailant. Teaming up with Edgeshot, the latter distracts The Crawler with his Spiral Spear Hand, forcing him to land on the rooftops. There, Jeanist and Edgeshot recognize him as the unsung hero from the Sky Egg Bombing, and reveals that they are aware that someone is out to get Kazuho Haneyama, so they want to win back his faith in the Pros.

Before Koichi could slip away, Jeanist binds his jacket into a straitjacket using his Fiber Master Quirk. The Crawler attempts to slide away and jump off the building, but Jeanist prevents him from falling with a web of threads using his Super Move, Catching Cradle, while Edgeshot uses his Fishhook Snag to catch him. Koichi's restrains loosened up, and he uses this opportunity to slip out and escape. Best Jeanist and Edgeshot are surprised at Koichi's skills, and the former admits that they have underestimated Koichi's sheer resolve. Edgeshot follows up that capturing a desparate opponent will be a challenge, as this means they won't be able to prioritize their well being. Best Jeanist agrees, but clarifies that, as Pro Heroes, excuses are beneath them, so they set out to capture The Crawler.

As nighttime came, Number 6 cuts off all power in Naruhata by shooting an electromagnetic pulse into the sky. Best Jeanist, Edgeshot, and Ingenium soon make it to Koichi and Eraser Head's location. Using a make-shift string phone, Best Jeanist reassures the public, and the heroes are met with cheers. At Naruhata Station, the Heroes gather intel on how dire the situation is, learning that the blackout extends for kilometers and the roads and railways are suspended. They notice the similarities to the Sky Egg incident, and prioritize making contact outside Naruhata, with Jeanist heading out to deal with the civilians' needs.

Koichi walks in and thanks the heroes for their help before attempting an escape, but is restrained by Eraser Head, effectively putting him under arrest. Best Jeanist and Edgeshot ask why he didn't leave when he had the chance, to which Koichi says that he wanted to thank the heroes. Eraser Head offers to watch over Koichi while he head to the hospital to link up with Naomasa, which they agree to. While patrolling, Best Jeanist sees a civilian crying for help, and reaches out to assist. However, the civilian is actually one of Number 6's Anonymous, and Jeanist is caught off guard as they are about to explode.

U.A. Sports Festival Arc
Tsunagu watched the U.A. Sports Festival was impressed by the strength and skills that Katsuki Bakugo displayed during the event, but was unhappy with the boys aggressive behavior. After the Sports Festival, he sent Katsuki an offer for an internship.

Vs. Hero Killer Arc
When Katsuki chooses him for an internship, Best Jeanist introduces himself by admitting he does not like people like Katsuki and acknowledges that Katsuki probably only chose him as a mentor because he is in the top 5. Irritated, Katsuki replies that Best Jeanist was the one who sent the offer to him. Best Jeanist tells him that all of his other recruits were well behaved, unlike him. Although Best Jeanist admits that Katsuki has outstanding talent, he says the young man still needs to be taught how to display himself as a hero.

Irritated by the Pro Heroes lecture, Katsuki approaches Best Jeanist, forcing him to discipline Katsuki by using his Quirk to wrap him in denim threads, restraining him. Best Jeanist says that it’s his job to correct people like Katsuki, vowing that by the end of their week together, Best Jeanist's ideology about appearance, speech, emotional control, and personal morals would be woven into Katsuki's very being.

The next day, Best Jeanist tries to teach Katsuki the value of maintaining an elegant outward appearance. He tries lecturing Katsuki about the importance of good behavior and altered Katsuki's appearance to make him look less intimidating by combing his hair into a neat side part, similar to his own. This lead Katsuki to believe that he chose the wrong Hero to intern under. Katsuki's hair returns to its usual messy form shortly after.

At some point during the internship, while Best Jeanist was combing his hair, he asked Katsuki about his hero name. He tells him that all the names he had chosen had been rejected. Best Jeanist tells him that an alias represents what he wants to be and what he ought to be, so he asks him, when he becomes a second-year student and received his Provisional Hero License, to return to him and tell him his name.

After Hero Killer: Stain's defeat is published, Best Jeanist reminds all his sidekicks, including Katsuki, whose Hero costume had been changed by Best Jeanist, getting rid of his mask and Grenadier Bracers and having him wear a pair of smart denim jeans in place of his usual baggy pants, to remain calm and operate as they normally would.

Later on, Best Jeanist takes Katsuki on patrol. He tells Katsuki that Hero patrols dissuade Villains from committing crimes and says there is another reason. He asks Katsuki if he know what this other reason is, to which he answers that it is because they can beat up criminals on sight if they do commit a crime. Best Jeanist says this answer is wrong and that patrols help heroes maintain a strong public image and give civilians peace of mind. To emphasize his point, Best Jeanist waved at a group of school girls, who swooned seeing one of the Top 5 Heroes wave at them. Katsuki ends up getting into a spat with young children, making Best Jeanist comment about Katsuki having too much pride.

Hideout Raid Arc
Following the abduction of Katsuki Bakugo, Best Jeanist is recruited by Detective Naomasa Tsukauchi. Naomasa enlists Best Jeanist to the Hideout Raid Team, a fighting force tasked with infiltrating the League of Villains hideout in Kamino Ward. Alongside Edgeshot, Endeavor, Gran Torino, Gang Orca, Tiger, Mt. Lady, Kamui Woods and All Might, Best Jeanist attends a strategy meeting to rescue Katsuki Bakugo from the villains.

The Hideout Raid mission commences the next night. Just prior to the mission, Best Jeanist reminds Endeavor that he is an alumni when the latter complains about participating. Best Jeanist shares with everyone that he had Katsuki as an intern and worries that Katsuki's attitude might get him into trouble. Gang Orca is surprised that not even the elegant Fiber Hero could get through to him.

Best Jeanist leads the second squad to the Nomu production factory. Gang Orca and Mt. Lady help him successfully secure all of the Nomu. Best Jeanist restrains the majority of them with denim strings using his Quirk. Mt. Lady complains about the simplicity of their task, but Best Jeanist explains that the difficulty of the task doesn't take away from its importance. The hideout team is interrupted when a shadowy figure appears from the dark and Best Jeanist quickly restrains the man by tightening the fibers of his clothes. Mt. Lady expresses concern for the man but Best Jeanist states he cannot give the villains any slack. The villain frees himself and aims a large explosion at Best Jeanist and the squad.

Best Jeanist manipulates his allies' clothes and pulls them out of danger. He takes the brunt of the evildoer's blast and lies injured on the ground. The man levitates towards the Fiber Hero and commends his efforts to protect the other heroes. Best Jeanist recognizes the man as the leader of the League of Villains. He knows that this man's strength is comparable to All Might's, but believes that is no excuse not to act. Best Jeanist attacks, but is easily countered and crushed by an air cannon from All For One.

Defeated, Best Jeanist falls unconscious. He's later rescued when All Might, Endeavor, Edgeshot, and Kamui Woods arrive to defeat All For One.

Pro Hero Arc
In the second annual Hero Billboard Chart JP of the year, Best Jeanist is absent, as the announcer reveals he is taking a rest from his duties as a Hero for an extended amount of time. It is also revealed he has climbed from No. 4 to the No. 3 spot due to his participation in the Kamino Ward Hideout Raid.

Meta Liberation Army Arc
At some point prior to the Revival Celebration, Best Jeanist meets up with Hawks, and discuss about his health. Best Jeanist reveals he had lost a lung during the Kamino Incident, and not even Recovery Girl's help can recover the missing organ. However, this loss does not make him give up his plans of returning to the public eye.

Hawks responds how unfortunate things have turned out before brandishing one of his blade feathers at Best Jeanist. Later, it is revealed that Best Jeanist has gone missing, and that his sidekicks haven't heard from him in some time. Later, Hawks meets Dabi at a secret location where he shows him what appears to be Best Jeanist's corpse. Dabi is a bit suspicious, but allows Hawks to join the Paranormal Liberation Front.

Paranormal Liberation War Arc
Best Jeanist is approaching Jaku city in his plane after Tomura woke up and has been fighting the Heroes for some time, while Gigantomachia starts approaching the battleground. Impatient, he asks the pilot if they have arrived yet, because he told her to get him there in five minutes. The pilot retorts that if she were Hawks or Mirko she would have, but this is the best she can do. She also tells him to sit down because it is getting dangerous on the ground and his body hasn't fully healed yet. Best Jeanist reminds the pilot that there are still people whose lives are at stake, so his own safety shouldn't be a priority.

Before jumping out of the plane, Jeanist watches Dabi's pre-recording in which he reveals that he is Endeavor's son, Toya Todoroki, as well as his father's abuse. He also reveals that Hawks murdered Best Jeanist among other infamous actions and secrets. Best Jeanist realizes he was waiting to unveil all of this dirty information when the Heroes couldn't prevent mass destruction and the people's faith was starting to waiver. As Dabi prepares to finish Endeavor off, Jeanist stops the villain in his tracks by wrapping him with a wire, declaring that from now on, he's back on duty.

Using the wires he brought with him, he successfully binds all of the Lieutenants of the Paranormal Liberation Front with his Quirk, including Gigantomachia and an unconscious Tomura. Dabi is in disbelief seeing him alive since he was positive Hawks brought him a dead body, but Best Jeanist declares that Dabi overreached with his ambitions and now he will come apart like inferior denim.

Dabi manages to free himself by burning the wires, facing his brother Shoto. Best Jeanist starts faltering but tries to stand his ground, refusing to allow the No. 1 Hero to fall here, as Tomura woke up and gave Machia an order to break free, causing the Hero to struggle. Some of the Near High-End Nomu decided to intervene and start approaching Best Jeanist's location with an intent to kill him. All of a sudden, Lemillion appears and knocks the Nomu away.

The Nomus quickly recover from the blow, and prepare to attack Best Jeanist again, but this time Tenua, Nejire and Katsuki join Mirio to protect him. After they save the Hero, Best Jeanist asks the falling Katsuki if he's experienced the world, calling him 'Bakugo', but Katsuki replies that that name was only temporary. He reveals that, starting today, his real hero name is "Great Explosion Murder God Dynamight". Best Jeanist thinks that it's a childish name.

Best Jeanist continues to use all his might to hold Gigantomachia down, but because of his monstrous strength and Best Jeanist still hasn't fully recovered, Gigantomachia is about to break free from Best Jeanist's fibers, but fortunately Endeavor uses every bit of strength to knock the giant back, knocking himself out as a result. Gigantomachia starts losing strength, and Mirio explains that the sedative that the U.A. students force fed into the behemoth earlier is finally working.

With Gigantomachy weakened, Best Jeanist redirects his efforts to retain the League of Villains, a uses his super move Blackout Bind to choke the members of the League in his grasp to knock them unconscious. To his surprise, Mr. Compress uses his Quirk to gouge out a section of his own flesh, which gives his arm enough room to quickly escape and compress Tomura and Spinner.

Best Jeanist tries to take control of the fibers on his clothes to slow him down, saying that he has no hope of escaping with wounds that fatal, but Mr. Compress continues to use his Quirk to pop off parts of his body, as well as destroying his clothing. He also compress Dabi and Skeptic.

Then Mr. Compress frees Tomura and Spinner, asking the latter to wake up Tomura while he tries to buy time so they can escape as Mirio and Best Jeanist's cables charge toward them. Mirio easily defeats Mr. Compress, and between him and Best Jeanist they are about to catch Tomura and Spinner again. At that moment, All For One's consciousness takes possession of Tomura's body, and uses Radio Waves to blow Mirio, the cables, and all the other fighting heroes away, while also calls all the Near High-Ends for help.

The Nomu arrive quickly and proceed to grab "Tomura" and Spinner to make their getaway. Best Jeanist attempts to restrain them with the cables, while Nejire, Tenya and Mirio also trying to stop them, but they fail, and "Tomura" manages to escape along with Spinner and a large number of Near High-End Nomu. Despite the surviving heroes' attempts to stop them, All For One and his allies manage to escape.

For the next two days, the hero society goes into a deep crisis like never seen before. Shortly after escaping the battlefield, All For One attacks several prisons, rescuing his original body from Tartarus and freeing numerous villains. With everything happening, many Heroes cannot withstand criticism and social pressure, so they decide to withdraw and close their agencies, leaving many places with little protection from the growing number of criminal acts.

On the second day, Best Jeanist decides to accompany Hawks to his home, where his mother Tomie resides, taking him in her car. Hawks is still barely recovered from his injuries, needing a device to communicate with Best Jeanist. Along the way, they talk about how Best Jeanist managed to enter a state of apparent death to trick Dabi into allowing Hawks to enter the Paranormal Liberation Front.

Suddenly, Best Jeanist spots a group of Villains called the Glutton God Gang causing trouble at a marketplace. Best Jeanist steers his car and quickly defeats them. One of the bystanders thank him for apprehending the villains, as Best Jeanist asks him why the police or a local hero hadn't shown up. The bystander explains that the police are too busy with the prison breaks and most of the Pro Heroes have shut down their agencies after all the criticism being lobbed at them.

Best Jeanist ensures him that he will dispatch some of his sidekicks to protect the neighborhood, while he notices the civilians reactions. Among the crowd of civilians who congratulate him and thank him for his help, he sees several people seem upset, even hateful, towards the heroes. He even spots one of them wearing a support gear.

Afterwards, Hawks brings Best Jeanist to his house, wanting to confirm something before showing his face to the public again. He looks for his mother Tomie, only to discover that she had fled, leaving a farewell note, in which she apologizes to him since, as Hawks feared, she was forced to reveal everything she knows about her son Keigo Takami. Best Jeanist tries to console him but he tells him that when he abandoned the name ‘Takami’, and admits he feels relieved all of this has come back to him, and now that the Safety Commission has shut down, there is no one else around to give him orders.

He says to Best Jeanist that when people get backed into a corner or are truly free, that is when they show their true nature, and it is because of that he considered Twice to be such a good person due to his desire to help others, and how he wants to be just like that. He comments that even if what Dabi said about the Todoroki Family is true, he deeply believes things are different now. When Best Jeanist asks what he plans on doing next, Hawks answers that he is going to address his origins to help Endeavor, who he definitely knows is in trouble.

Best Jeanist and Hawks go to Grand Central Hospital to talk to Enji Todoroki, waiting outside the room when he is with his family and listening to the conversation between him and his wife Rei about their son Toya, as well as the determination of the entire family to stop him. Both heroes decide to enter the hospital room to speak with Endeavor, and apologizing for having eavesdropped on them, asking to help them in their proposed family outing. Rei kneels down and apologizes for what her son Toya did, which shocks both Best Jeanist and Hawks, who anxiously tells her not to worry about and apologize for eavesdropping them.

Hawks proceeds to inform Endeavor about everything that's happened within the past two days, and the terrible crisis that hero society is going through after All For One/Tomura Shigaraki managed to escape. After telling him his only option is to fight, Hawks and Best Jeanist gleefully respond that they'll be assisting him as a team-up with the top three, so he and his family don't have to take on the burden alone. Endeavor tearfully accepts their proposal and this new resolve to move forward. But before getting down to business, they first have to clear up the whole One For All and Izuku Midoriya thing.

Best Jeanist and Hawks head to the room where Izuku is resting, still unconscious and wounded from his battle against Tomura. Along the way, Best Jeanist sees that Katsuki is being dragged away by his classmates as he yells at Midoriya to wake up. Relieved that he is lively as ever despite his injuries, Best Jeanist greets Katsuki, addressing him by his entire hero name. As they prepare to enter Izuku's room, Tenya Iida explains that All Might is with him alone.

Both heroes knock on the door of the room, and Hawks asks All Might to talk to them as they want to know about the connection between Izuku Midoriya and the mysterious "One For All" that Tomura was so desperately trying to take over. All Might accepts his request, and after taking them to a more private area of the hospital, he decides to tell them everything.

Three days later, as people continue to feel uneasy, Endeavor, Hawks, and Best Jeanist put on a press conference to address the public. In addition to confirming and clarifying many of the accusations that Dabi made about Endeavor and Hawks, the three are aware of the lack of trust towards the heroes, especially after Tomura raided numerous prisons to free the villains held there after escaping from the battle.

Best Jeanist adds that due to the significant amount of heroes resigning, it's become harder to protect the public so they have started a plan for help protecting the civilians, in which many of the heroic institutions are going to be used as evacuation shelters for civilians in need. Many of the reporters protest these measures, but the three assure that, despite the harsh criticism of the heroes, there are still many of them who keep fighting to restore peace.

Tartarus Escapees Arc
Afterwards, Best Jeanist forms a team with Endeavor, Hawks, All Might and Izuku Midoriya in order to track down Tomura, All For One, and the remnants of the Paranormal Liberation Front, coming up with a plan to use Izuku as bait to lure them out. While All Might and Deku are handling other villains, Best Jeanist goes with Endeavor and Hawks to cover more ground and deal with rampant criminals.

Some time later, Endeavor defeats and captures some robbers. After turning them over to the police, he meets with Hawks and Best Jeanist, with the latter assuming that the captured villains are escaped convicts but not affiliated with All For One, which Endeavor confirms.

The three are then approached by a mob of protesters, who insult them and accuse them of being responsible for the current situation for letting Tomura get away and releasing the prisoners. Best Jeanist has to use his Fiber Master Quirk to protect himself and his teammates from the objects that are thrown at them with contempt. The protesters continue to deride them as fakes as they drive away.

While driving, Hawks receives a call from Edgeshot informing them that he hasn't made much progress in his investigation investigating the Paranormal Liberation Front. The three agree to give Izuku more space to prevent the press from finding out that he is the one the villains are looking for.

The Heroes proceed to discuss what the villains' have planned next, assuming the Tartarus escapees had received some orders from All For One to capture Izuku. Best Jeanist says that with the heroes falling apart, if he was All For One, he would go on the offensive, but Endeavor doubts All For One is going to do that at the moment, as his main priority is to hijack Tomura's body once the maturation process is complete, so he can take the One For All from Izuku.

Then Hawks admits he doesn't understand the reason of why Tomura's rage is so important to All For One in this process. Best Jeanist says that it takes a strong will to steal a Quirk bearing the will of eight other people, but Hawks replies that after hunting down OFA's successors for decades, All For One should have enough hatred. Best Jeanist believes maybe he doesn't have enough, but Hawks suggests he has none at all, since he is always seen smiling. Endeavor concludes that there may be something's missing in All For One's soul.

Nevertheless, since the villains they have rounded up have no useful intel, they decide they may have to take the fight to the enemy and increase their search, even if it means reducing the number of people keeping peace on the street. Suddenly, Best Jeanist hears a notification that Izuku's GPS signal is gone.

It turns out that Izuku was being attacked by one of All For One's assassins, Lady Nagant, who was Hawk's former mentor. Izuku was outmatched, but he succeeded in defeating her, having a change of heart after witnessing Izuku's true heroism. However, All For One anticipated that Lady Nagant would be defeated, so he rigged a Self-Destruction Quirk inside of her as a failsafe. Thankfully, Hawks flies in on the scene and catches Lady Nagant, while Endeavor follows behind. Before she passed out, Lady Nagant managed to reveal the location of All For One's supposed hideout in Haibori Woods.

The three heroes, along with Izuku and the Lurkers, arrive at the mansion that was the former headquarters of the Creature Rejection Clan, but find it completely empty. The only thing they find is a holographic video where All For One sarcastically taunting Izuku, vowing to break him both body and spirit just as the mansion explodes. Fortunately, everyone is able to escape the trap unscathed, but the explosion destroys any trace of the League.

Some time later, Best Jeanist, Endeavor, Hawks, and the Lurkers meet privately in a warehouse, where they discuss how the search for All For One, Tomura, and their allies becomes more complicated as more heroes quit due to of not being able to withstand the pressure and criticism. Best Jeanist emphasizes that it has reached a point where any hero could snap anytime and it would not come as a shock. Endeavor adds that the retired heroes are leaking information regarding One For All, and the public are getting close to uncovering the truth about Izuku.

Then they receive a notification that Izuku has defeated another of All For One's agents. At that moment they receive a message that Izuku has defeated another of the All For One agents, but later they discover that he has decided to continue the search alone.
