Chapter 3.2 (Team-Up Missions)

The Heroes Have Come! (ヒーローたちがやつてまた！) is the second bonus chapter of My Hero Academia: Team-Up Missions, written and illustrated by Yoco Akiyama.

Summary
A boy named Tsuyoshi, who possesses a Bristle Quirk making his hair super hard, heads out to the park to play with a special soccer ball he just bought, while his mother tells him to watch out for villains. Once there a trio of thugs show up to try and take the ball, where he panics wondering if someone will help. All Might suddenly appears, knocking the thugs out and scaring them off, but they manage to escape with the ball anyway. Izuku Midoriya arrives shortly behind All Might, where they introduce themselves to the boy as heroes who protect people from villains. Izuku tells the boy he is a hero-in-training accompanying All Might on a mission. Tsuyoshi asks if they can get the ball back, which they are about to head off to do, only for All Might to transform back into his true form falling over. Tsuyoshi believes that All Might's Quirk lets him transform, but Izuku and All Might explain that it's just something he does by flexing and that because of a fight with a villain, he can't maintain his muscle form for long. Izuku instead proposes to ask *them* for help.

He invites the rest of his classmates from 1-A at U.A. High to assist in retrieving the ball, which most are happy to do, except for an ambivalent Katsuki Bakugo, leading to a lecture from Tenya Ida. Tsuyoshi notices most of the eccentricities of the class, including Katsuki brawling with Izuku, Mina and Tsuyu pressuring Ochaco about her crush, Minoru staring at Momo's boobs, Yuga and Fumikage mumbling to themselves, and Shota Aizawa sleeping, and wonders if they're really trustworthy for the job.

Out in the city, Kyoka Jiro uses her Quirk to listen through the walls and tracks down their location. Tenya uses a Reciprio-Burst to quickly blast his way over to the thugs, only to find a giant dinosaur villain has already defeated them and is about to take the ball for himself. As Tsuyoshi wonders how anyone could fight a villain that big, Katsuki jumps in with a Howitzer Impact, followed by an Ice Wall from Shoto Todoroki to immobilize it, causing the boy to exclaim how strong the students are. Izuku then has Tsuyu throw him into the air as he prepares to knock the villain out with a Smash. Tsuyoshi asks Shoto what Izuku's Quirk is, which he says is Super-Strength, just like All Might.

With all the villains captured, Izuku returns the soccer ball to Tsuyoshi, as he thanks everyone for everything they did, saying that heroes are really cool, as they all head out.
