History
At some point, Moe became one of the many sidekicks at the Endeavor Agency, as well as one of the Flaming Sidekickers.

Final Performance Arc
After the first bombing of Naruhata by Bee☆Pop, Burnin and her teammates from the Flaming Sidekickers participate in the hero patrols, under the Endeavor's command. Since Bee☆Pop had promised to return, Endeavor devises a plan to finish her off.

A few days later, Bee☆Pop attacks Naruhata again, but this time the heroes deployed there are dedicated to evacuate the civilians. Once they report all citizens have been evacuated, the Flaming Sidekickers send up signal flames to Endeavor to let him know that he can uses his Hellflame Quirk without worry.

Endeavor uses his Super Move Hellfire Storm to defeat Bee☆Pop, but when Burnin spots The Crawler she yells out for Endeavor, and he is forced to cancel his attack, much to his displeasure. Since he needs a few minutes to cool down, Endeavor orders to signal the other heroes to try to capture the villain and the vigilante. After this, Burnin just watch along with her teammates the development of events, such as the fight between The Crawler and Bee☆Pop, as well as The Crawler flying away from Endeavor with an unconscious Pop☆Step in his hands.

Naruhata Lockdown Arc
Several weeks later the Naruhata Lockdown incident takes place. The villain Number 6 attempts to kill Koichi, and during the fight, he transforms into a being of energy that splits into several mini bombers, wreaking havoc over the city. Many heroes head to Naruhata to face the threat, including Endeavour, who is accompanied by Burnin.

Seeing the chaotic mess, Burnin warns Endeavor that they can't do anything yet, but the hero corrects her by saying that the longer they wait, the more destruction the villain will cause, so they must act now, assuring his sidekick that he will take responsibility for any damage he can cause, which surprises her. As Endeavor prepares to attack, All Might appears and punches all the bombers into the sky, allowing the Flame Hero to destroy them all with a Flashfire Fist: Prominence Burn without causing any damage to the city.

Once the crisis is over, Burnin leaves the place with Endeavor, who is upset by All Might's intervention.

Endeavor Agency Arc
As soon as Izuku Midoriya, Shoto Todoroki and Katsuki enter the headquarters of Endeavor Agency, after their battle in the streets against Starservant, Moe and Endeavor's other sidekicks give them a hot welcome. She starts talking about the amount of work the sidekicks face, and tells the students that they are going to have to work hard to stand out.

Izuku recognizes her, and she clashes with Katsuki, then tells Shoto not to make himself comfortable just because he is Endeavor's son. She tells Izuku and Katsuki that since Endeavor only requested Shoto, they will probably work with the Sidekicks, much to Katsuki and Shoto's displeasure.

However, Endeavor had received a secret message from Hawks warning him of the Paranormal Liberation Front and tells the three students that he will train them personally. Later, when Izuku is explaining his Air Force technique to Endeavor, Burnin has a hard time understanding and is surprised when Endeavor follows what Izuku is saying.

The students stay with the Flaming Sidekickers at Endeavor Agency, which is equipped with accommodations. While there, Burnin asks them about their progress and if they have already captured a villain faster than Endeavor, which they had been tasked with doing. Seeing their beat-up costumes, she comments to herself that she doesn't have to say anything to get them to work harder.

My Hero Academia: World Heroes' Mission
The Endeavor Agency is summoned to participate in a global hero operation against Humarise, an anti-quirk sect that had committed an act of terrorism by detonating a Trigger Bomb in a city, killing hundreds of people. As a member of the agency, Burnin accompanies Endeavor and his trainees to Otheon, to raid the sect's branch there.

The Otheon task force raids the Otheon branch, and though they are met with fierce resistance, the heroes only arrest minor members, but do not find the leader Flect Turn or any of the bombs. And the results were the same in the other Humarise branches around the world. Because of this, the World Heroes Association Director orders all the task forces to remain on alert in the countries that were assigned to them. Otheon's team leaves to a hotel in the capital that they use as a temporary base.

During the stay in Otheon, an incident occurs in which Izuku unknowingly seizes a very important device for Humarise, which turns out to be the key to deactivate the Trigger Bombs that the cult has hidden in different cities where its branches used to be. Despite this, Flect Turn activates the bombs and broadcasts globally that they will explode in less than two hours. His goal is to kill the greatest heroes in the world, and to further attract the greatest number of them, he announces in which cities are found, Otheon being one of them.

Otheon Task Force immediately heads off to search for the bombs and help the terrified civilians. During the search, Endeavor receives a message from the WHA headquarters informing him that Izuku, Shoto and Katsuki have found a way to stop the detonations and that they are heading to Humarise secret base to defuse the bombs. Burnin suggests that they should go support them, but Endeavor tells her they don't have time and have to stay behind to deal with the bombs, putting his trust in his trainees.

Soon they are informed by Clair Voyance that she has found the bomb. Endeavor and Burnin immediately fly there, but as soon as they arrive, they are attacked by members of Humarise, stationed there to protect the weapon from the Heroes. After fighting them, Endeavor manages to reach the Trigger Bomb and take it as high as possible into the sky, being protected by Burnin and Clair from the members of Humarise who try to stop him.

Fortunately, Izuku and the others managed to disable all of the Trigger Bombs, defeating Flect Turn and the higher ranking members of Humarise in the process. After waiting days for the students to recover from their injuries, Burning returns to Japan along with the rest of the Endeavor agency.

Paranormal Liberation War Arc
The months go by until it's late March. Thanks to the police investigation and its spy Hawks, the Hero Public Safety Commission has found out the plans of the Paranormal Liberation Front and its allies. With this info, the Commission organized a large force of Pro Heroes, divided into several teams to take down the villain organization.

A team of heroes has the mission of storming the main headquarters of the Paranormal Liberation Front, while another team lead by Endeavor will do the same at the Jaku General Hospital, where the Nomu are created. Finally, a third team, made up mainly of students and lead by Burnin, will be in charge of evacuating the residents of a city near the hospital and taking them to a safe place. When everything is ready, Burnin signals the students to start evacuating the citizens.

The evacuation of the city proceeds smoothly as the heroes raid the hospital. Burnin yells to anyone in the neighborhood to let the Heroes know if they are unable to get up and out on their own, as there is a chance the city will become a counter-villain battle zone. Shortly after, the hospital is destroyed by Tomura Shigaraki due to his decay, which extends to the city itself.

Some students use their Quirks to try and push back or stop the decay but they fail, so Burnin orders everyone to fall back while trying to escape with the civilians. Burnin tries reaching out to the Hospital Raid team hoping for a response on the situation but receives none. All members of the evacuation team manage to get to safety, and Endeavor finally radios her. He explains he is fighting Tomura, but for some reason, the villain is heading to the city in search of "One For All", although neither Endeavor nor Burnin know what that is, but Deku overhears her and knows what is going on.

Deku tries calling out to her, but Burnin is too busy reorganizing the hero forces to fight Tomura, ordering the students and civilians to evacuate as fast as possible. Knowing that Tomura is after him, Deku moves away from the city so as not to put anyone in danger, using the private channel to explain to them that he is Tomura's target.
