History
Although little is currently known about it, Kamui Woods had a very dark childhood, and it is said that his childhood was made into a popular documentary.

Entrance Exam Arc
Kamui Woods confronts a villain using a "monster form" Quirk. Reading out his charges, Kamui Woods asks the villain to step down while dodging a series of attacks from the giant. After the villain refuses to comply, Kamui prepares to use his Lacquered Chain Prison to stop his movement, when suddenly Mt. Lady intervenes in the fight and knocks out the villain, stealing all of Kamui Woods' credit. In this confrontation, it is revealed that Kamui has a large fan base.

In the afternoon, an incident occurs when the Sludge Villain tries to take over Katsuki's body. He envelops Katsuki's body in sludge and takes control of his Quirk. The explosions draw the attention of Kamui Woods and nearby Pro Heroes. Kamui Woods saves nearby civilians but due to the fire generated by Katsuki's explosions, he can not help him for fear of burning himself.

Fortunately, All Might appears and with a Detroit Smash he defeats the Sludge Villain while saving Katsuki and Izuku (who tried to save Katsuki as well). All Might's blow is so powerful that the villain's mudy body is scattered throughout the street, so Kamui helps collect the remains and putting them in bags to deliver to the police.

Along with Death Arms, he also scolds Izuku for his reckless attempt to rescue Katsuki despite being Quirkless.

U.S.J. Arc
He and Mt. Lady have trouble dealing with Habit Headgear, as he is holding hostages, until All Might shows up, beats him up, and saves the hostages. Although he and Mount Lady are grateful, they complain that All Might will put them out of a job.

U.A. Sports Festival Arc
Kamui Woods, Mt. Lady, and Death Arms are assigned to guard duty for the U.A. Sports Festival. During the patrol, Kamui Woods reproaches Mt. Lady for using her sex appeal to obtain food for free. After Mount Lady seduces her way to lunch, the three talk briefly about how the school has employed Pro Heroes to secure the facility. Kamui complains not being able to watch the competition and scout new talents, something Death Arm agrees with.

Later, after the rules of the Cavalry Battle have been explained, Kamui Woods, Mt. Lady and Death Arms are in the break room and start discussing the U.A. Sports Festival. Death Arms says that the Sports Festival is all about preparing the young heroes for the real world of heroes and that the Obstacle Race was a way of showing that you need to kick down others to show what you are able to do. Mt. Lady, after mentioning that she feels bad about having done that to Kamui Woods, mentions that Heroes need to work together in order to accomplish a goal and the Cavalry Battle is a good representation of that.

Later, they return to their surveillance duties. Mt. Lady watches the fight between Denki Kaminari against Ibara Shiozaki, in which Ibara easily wins. Impressed by her, Mt. Lady tells Kamui Woods that Ibara would make the perfect sidekick for him. Kamui comments that he wished he could have seen her closer, before telling his partner to get back to work.

Hideout Raid Arc
The League of Villains attacked the training camp, injuring numerous students and kidnapping Katsuki Bakugo. Fortunately, the police investigation finds the hideouts of the League, and organize a rescue operation to save Katsuki. Kamui joins the Police Force and many Pro Heroes to participate in it. The heroes are divided into two groups, one will be in charge of storming a Nomu factory and the other to raid the main hideout of the League.

Once everything is ready, the Hideout Raid Team begins their assault against the League of Villains. All Might breaks in the main hideout with a smash attack after the Police distract the villains with a fake pizza delivery. Tomura orders Kurogiri to create portals, but Kamui Woods swings in and uses his Lacquered Chain Prison to restrain the villains, which prevents Kurogiri from creating an escape route. Dabi tries to burn the wooden restraints, but Gran Torino swoops in and knocks him out with a swift kick to the head.

All Might declares that it's their win when suddenly All For One intervenes, using his Warping Quirk to transfer Nomu through them Kamui Woods asks for reinforcements, but Naomasa Tsukauchi, Endeavor, and the Police Force are being attacked by dozens of Nomus as well. All For One also manages to transport all the members of the League of Villains and Katsuki out of the hideout. Kamui Woods apologizes for his failure in restraining the League of Villains. Edgeshot tells him not to worry since they could not do anything either.

All Might gets rid of the Nomu who attack him and head to the Nomu factory, while the rest of the heroes confront the creatures. After the dozens of Nomu are defeated, Kamui Woods, Endeavor, and Edgeshot go to All Might's location after defeating the Nomu where he is battling All For One. Kamui Woods rescues the heavily injured Mt. Lady, Best Jeanist, and Gang Orca. Kamui Woods tells Mt. Lady that she did well.

Katsuki is rescued and All Might manages to defeat All For One, but almost the entire League manages to escape, in addition to All Might no longer being able to work as a hero after having lost his Quirk.

Remedial Course Arc
Apparently, Edgeshot had been impressed by Kamui during the Kamino Raid that he 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".

Endeavor Agency Arc
By the end of the year, due to the increase of the villain activities, the Hero Public Safety Commission demands 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.

My Hero Academia: World Heroes' Mission
Kamui and the Lurkers learned that Humarise has detonated a Trigger Bomb in a major city, killing thousands and destroying the entire infrastructure. In response to the act of terrorism, the World Heroes Association mobilizes the largest anti-terror joint task force. The Lurkers join the Egypt Task Force with their Work Study interns, Denki, Hanta, Minoru, and Ibara, where they meet Salaam, Egypt's top Hero.

The heroes lead an assault on a Humarise forward operating base in Cairo. Despite their successful raid, the heroes fail to locate the Trigger Bombs or any of the Humarise's leaders. The Egypt team were ordered to be on standby. The operation is compromised when the Humarise had publicly broadcasted to the entire world that they have planted the Trigger bombs in over twenty-five cities, one of which is Cairo, and they will detonate the bombs in two hours to "cleanse" the population of their Quirks. As a result, Cairo is locked in a state of anarchy and chaos, so the Egypt team scrambled to quell the hysteria and locate the bombs.

Finally the heroes manage to find the bomb, having to engage in an all-out war against the Humarise agents who protect it. During the battle, the heroes are informed that Izuku's group intend to storm Humarise's main base in order to defuse the bombs worldwide.

The Lurkers manage to reach the bomb just as the countdown ends, but after a few seconds nothing happens, indicating that Deku's group had managed to deactivate the Trigger Bombs in time, saving the world from catastrophic destruction. With the main threat neutralized, the heroes defeat the last of Humarise's agents and seize the device, celebrating the victory. Once the crisis has been averted, the team leave the country.

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. Kamui Woods, along with his teammates Mt. Lady and Edgeshot, is part of a large force of heroes in charge of raiding the Gunga Mountain Villa, the headquarters of the Paranormal Liberation Front.

When the signal is given, the heroes begin their assault on the Gunga Mountain Villa, catching the PLF members off guard. This allows the heroes to defeat large numbers of foes before they can mount a proper defense. Kamui Woods uses his Ultimate Move Lacquered Chain Prison to restrain the PLF members with efficiency.

With his actions and those carried out by his allies, it seems that the heroes are about to win on that front despite the growing resistance of the Paranormal Liberation Front. 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, ready to obey the orders.

Mt. Lady does her best to hold the giant back,, but she barely manages to stop him and is dragged. Kamui follows them as he swings across the trees, carrying Midnight on his back. He worries for Takeyama when Gigantomachia swats her away as he decides to take a shortcut to Tomura.

Despite his concerns, Midnight convinces him to keep moving and asks him to take her close to Gigantomachia's face so she can use her Somnambulist Quirk to stop him. Kamui agrees but he gets burned by Dabi and Midnight is shot down by Mr. Compress. Despite his burns, he manages to entangle Mt. Lady's arm with Gigantomachia's leg, slowing the giant down.
