When All Might and Izuku we're discussing about the incoming Sports Festival, F/n entered the room as he is called by Toshinori.

All Might:"Ah, F/n my boy, glad you could join us."

Izuku:"Hey F/n."

"Eh, overslept, probably because of my overcharged Quirk from the U.S.J incident."

All Might:"No matter, come take a seat beside Young Midoriya."

As All Might instructs both Izuku and F/n to use the Sports Festival as a chance to debut as the new Symbol of Peace. However, Izuku is skeptical about his ability to fulfill All Might's request. All Might encourages his protege to aim for the top, to never settle and to remember the emotions he felt while training at Dagobah Municipal Beach Park. He turns to F/n, and tells him about the incredibly unique Quirk he has been given.

All Might:"I assume you're aware of the powerful Quirk that YOU have."

"Well, yeah, it was from my mother."

Once the school day ends, Class 1-A's students are unable to leave class because the exit is blocked and crowded by students from other classes. Katsuki says they're on there to scout out the competition and then instructs them to move out of his way. A student from the general studies course confronts Katsuki and issues a declaration of war to him and his class. The boy explains that if students from other courses do well in the exam, they can be moved into the hero course. He declares war on Class 1-A because he plans on taking their place in the Hero Course.

Next, a student from the Class 1-B abruptly arrives claiming he wanted to see the Class that defeated real villains, but his annoyed to find a bunch of condescending brats. Many of the students in Class 1-A worry that Katsuki has ruined their reputation and caused all the other classes to hate them.

Katsuki tells them that it doesn't matter and it's only important that he beats them in the festival. Izuku notices Katsuki's ambition and recalls the conviction of both Tenya and Ochaco as well. He is ashamed to have doubted his own convictions and decides to devote himself to training for the next few days. While he trains seaside, his fellow classmates train at the Replica City District and their own homes. 

Two weeks later the day of the U.A. Sports Festival finally arrives. Izuku is encouraged by his mother to do his best as he leaves for school. The school has increased security and has the festival broadcasted live. Mount Lady, Kamui Woods and Deatharms are employed as security. After Mount Lady seduces her way to lunch, they talk briefly about how the school has employed Pro Heroes to secure the facility. 

In the Class 1-A waiting room, students change into their P.E. uniforms for the festival, making it fair for everyone since they won't be wearing costumes. Tenya enters the room and warns his peers that they are about to enter the arena. Before they do, however, Shoto approaches Izuku and F/n.

With the entire class listening, Shoto explains that although he is stronger than Midoriya, the latter has the number one hero in his corner. Shoto continues by telling Izuku that he will defeat him in the festival.

Shoto:"Listen, Midoriya and L/n, I'll beat you in the festival if it's the last thing i'll do."

F/n:"You don't have to be so into the game to beat us. Jeez, calm the fuck down."

Midoriya:"Y-yeah, come on, we're all fiends here.."

Eijiro:"Alright! Break it up you three!"

Shoto:"I'll see you there.."

Eijiro tries to diffuse the situation, but Shoto refuses him and moves to leave the room. Izuku stops him and admits that although Shoto has more potential then anyone in the hero course, Izuku says he will be aiming for the top just like all the other students in the school. 

F/n:"Good speech, Midoriya, holy crap."

Class 1-A walks out to the Freshmen Stage of the Festival Stadium and the U.A. Sports Festival officially begins. The other freshmen classes also arrive. The Chief Referee for the Festival: Midnight, asks for the student representative, Katsuki Bakugo to lead the pledge. Instead, Katsuki takes the stage and announces to everyone that he will win the Festival.

F/n:"Oh god...he'll ruin this for us...in 3"

Katsuki:"Let me just say.."

F/n:"2...."

Katsuki breaths in to say what he wants to say to the crowd.

F/n:"1..."

Katsuki:"I'm gonna win."

Garnering boos from all the students. Izuku notices that Katsuki is pushing himself while making targets of Class 1-A at the same time. F/n then smacked the back of Katsuki's head for saying that in front of everyone.

Katsuki:"Fuck! What the hell was that for?!"

"Ask that yourself, jackass..."
