Sky Egg Arc
Edgeshot accepts Makoto Tsukauchi's invitation to participate in the farewell show dedicated to Captain Celebrity at the Tokyo Sky Egg on the occasion of his return to the United States. Once on stage, he performs some ninja skills alongside Edgeshot and Airjet's Quirks.

However, during the event, the Tokyo Sky Egg is attacked by creatures known as Bombers, sent there by villain Number 6 to kill Captain Celebrity. To achieve it, he orders the bombers to damage the structure, leaving Captain Celebrity completely defenseless to the Bombers by having to use his strength to prevent the building from collapsing.

In one of the rooms of the Sky Egg, the heroes and show staff discuss the situation. They quickly organize to defeat the creatures and protect the people there.. Edgeshot is part of the group of heroes in charge of facing the Bombers. Once outside, Edgeshot uses his Foldabody Quirk on the Bomber that was previously attacking Captain Celebrity. Edgeshot pierces the creature thanks to his Foldabody, and Best Jeanist uses his Fiber Master Quirk to catch it and leave it hanging.

After the Bombers are defeated and the building is secured, Edgeshot goes to check on Captain Celebrity's status. He is covered in bruises from the blows of the Bombers, but thanks to Koichi protecting him, he survived and was able to continue holding the Tokyo Sky Egg, but then exhaustion and injuries finally cause his Flight Quirk to fail and he plunges, with Koichi jumping unconsciously to save him. Edgeshot quickly prepares to save the two.

Just in that moment, in retaliation for the heroes' intervention, Number 6 orders the last Bomber to self-destruct in a large explosion, causing the building to collapse. Fortunately, All Might arrives in time and manages save everybody's lives.

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

Naruhata Lockdown Arc
Edgeshot 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 Best Jeanist, he 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 reveal 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 Ultimate 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 once again.

That night, 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. The heroes reassures the public, and they are met with cheers. At Naruhata Station, the Heroes gather intel on how big the situation is, learning that the blackout extends for kilometers and the roads and railways are suspended. They notice uncanny similarities to the Sky Egg incident, and prioritize making contact outside Naruhata, with Edgeshot surveying the area and making contact with Naomasa.

Koichi 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 in the air, Edgeshot sees a civilian crying for help, and reaches out to assist. However, the civilian is actually one of Number 6's Anonymous, and Edgeshot is caught in their explosions.

Hideout Raid Arc
Following the Vanguard Action Squad's invasion of U.A. High School's Quirk Training Camp, Edgeshot is enlisted by Naomasa Tsukauchi to the Hideout Raid Team. Alongside Best Jeanist, Endeavor, Gran Torino, Gang Orca, Tiger, Mt. Lady, Kamui Woods, and All Might, Edgeshot attends a strategy meeting to rescue Katsuki Bakugo from the villains.

The next night, the Hideout Raid Team arrives at the League of Villains' headquarters. Edgeshot knocks on the door, pretending to be from Kamino's Pizza Delivery. All Might and the others take advantage of the distraction burst in through the opposite wall. Kamui Woods restrains all the villains with his Quirk and then Edgeshot uses his powers to slide through the door. He tells the villains people often neglect defense when they're on the offense and then unlocks the door and lets in the police force hiding behind it.

Kurogiri tries to Warp his allies away using his Quirk, but Edgeshot stops him by using his Thousand Sheet Pierce technique. The Ninja Hero manipulates the thinness of his body and stabs Kurogiri to cut off his blood flow in order to knock him unconscious. Then he turns to Katsuki Bakugo and tells him he took advantage of a weakness the young man exposed during a fight with the Warp Villain. Suddenly black liquid appears and begins warping Nomu into the hideout. Gran Torino yells for Edgeshot to stop Kurogiri. The latter confirms that this isn't Kurogiri's doing because he's still out cold. The black liquid even manages to warp Katsuki away.

The black liquid begins to take hold of the villains as well. Edgeshot, Gran Torino, and All Might rush to restrain them, but they're all warped away in time. Kamui Woods apologizes for allowing them to escape. Edgeshot combats a Nomu and knocks it out before replying that it wasn't the hero's fault. The Ninja Hero surmises that the warping Quirk targeted specific people, unlike Kurogiri's Quirk. All Might and Gran Torino leave the remaining Nomu to Edgeshot, Kamui Woods, and Endeavor and go after the League of Villains Leader at the Nomu factory.

After dealing with the remaining Nomu, Naomasa asks the heroes to follow All Might and help him against All For One. Edgeshot and Endeavor arrive in time to stop All For One from blasting a weakened All Might. Endeavor yells at All Might for entering a weakened form and All For One asks that he be quiet if he only came to encourage the Number One Hero. Edgeshot refutes this and attacks All for One. He tells All For One the heroes came to assist and stretches his limbs to try and stab the villain. All For One evades Edgeshot's many attacks and eventually blows him and Endeavor away with an air cannon attack.

Thanks to the support of many, All Might is able to defeat All For One. As the world watches via the media All Might enters his muscular form and raises his fist in victory. Edgeshot worries that All Might is pushing himself, but Gran Torino tells him to let the Symbol of Peace be because he still has people to inspire.

Remedial Course Arc
Impressed by Kamui's actions during the Kamino Raid, Edgeshot invited him to team up together, which he accepted. Kamui was so happy that he sobbed for two hours. Later they would invite Mt. Lady to join them. There had been rumors for a while about their team up, before it finally became official, calling themselves "The Lurkers".

Pro Hero Arc
The Hero Public Safety Commission invites Edgeshot to the first Hero Billboard Chart JP since the Kamino Incident. He is announced to have moved up to the rank of the No. 4 Hero who's approval ratings and conflict resolution count have skyrocketed since All Might's retirement. The new No. 5 Hero Mirko taunts Edgeshot for joining a team and he replies for her to stay quiet while they're in public.

An interview reveals to the Ninja Hero that he would've been the No. 3 Hero if rankings were purely based on approval ratings. Edgeshot replies that he isn't concerned with the numbers and replies that it's more important to strive to create peace. No. 2 Hero Hawks interrupts Edgeshot's speech and claims nobody cares what the heroes say. Edgeshot and Mirko comment that Hawks is known for throwing everyone for a loop.

Endeavor Agency Arc
By the end of the year, due to the increase of villain activity, the Hero Public Safety Commission demand all the student heroes for all academies to undergo practical field training. Denki Kaminari, Hanta Sero, and Minoru Mineta from Class 1-A, and Ibara Shiozaki from Class 1-B join The Lurkers.

Edgeshot also receives a copy of the Meta Liberation War book.

Paranormal Liberation War Arc
By the end of March, thanks to the police investigations, and the information leaked by Hawks, who was acting as a spy, the Hero Public Safety Commission organize the Heroes and the Police Force to take down the Paranormal Liberation Front. Edgeshot, along with his teammates Mt. Lady and Kamui Woods, is part of a large force of heroes in charge of raiding the Gunga Mountain Villa, the headquarters of the Paranormal Liberation Front.

While the heroes wait for the signal to attack, Edgeshot comments that all the PLF bases all over the country are surrounded by heroes. Fat Gum can't help but be impressed that the villains' whole activities have been figured out. After the hero team led by Endeavor start to storm the Jaku General Hospital, the Villa Raid Team begins their assault on the Gunga Mountain Villa, catching the PLF members off guard.

The soldiers rush out of the mansion to confront the heroes and one of the PLF lieutenants attacks them with an electric shock, but his attack is canceled by Denki Kaminari. The villain prepares to unleash an even more powerful shock, but before he does so, Edgeshot zips past him and several other PLF soldiers using Thousand Sheet Pierce to prevent them from breathing by placing tiny holes in their lungs. This allows his fellow heroes to easily defeated and restrain the villains.

His actions and those carried out by other heroes achieve that little by little they are winning on that front, despite the increasing resistance presented by the Paranormal Liberation Front soldiers. This situation drastically changes when, at the front of the hospital, Tomura Shigaraki awakens and orders Gigantomachia to reunite with him, bringing with him the Lieutenants of the army. The hulking beast emerges from the bunker in which he was trapped, and disposes of all the heroes who try to stop him.

Worse, with his actions, Gigantomachia also allows many of the members of the army that were with him to also go out to aid his comrades. Among them is Re-Destro, who also emerges from the bunker with his Stress Quirk activated. Edgeshot and several heroes quickly prepare to face him, as Re-Destro is ready to fight them and orders the other members to follow the giant and begin their revolution.

Gigantomachia, however, brought most of the heroes' attention to himself, which left Edgeshot fighting against Re-Destro alone. After a long battle, of which details are unknown, Re-Destro's mechanical legs were broken once again and Edgeshot managed to pierce through his body using his Quirk, defeating him, though the hero was visibly exhausted from the fight and moderately injured. Re-Destro was then arrested, alongside Geten, Trumpet, and other Liberation warriors.
