History
Although little is currently known about it, Kamui Woods had a very dark childhood, and said 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.

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.

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.

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.

Kamui agrees but he gets burned by Dabi and Midnight is shot down by Mr. Compress. Despite his burns, he managed to entangle Mt. Lady's arm with Gigantomachia's leg, slowing the giant down.
