The chapter starts off with Tsuyoshi approached by a group of thugs that threaten him and steal his ball, but he's saved by All Might (in his muscle form). AM introduces himself and Deku to Tsuyoshi, but then he loses his muscle form and Deku explains that this is the real AM.
Deku introduces the rest of Class A to Tsuyoshi and explains they are heroes in training from U.A. Academy. Deku wants to help him get his soccer ball back, and Ochako says excitedly "yes let's do it!" Bakugou scoffs and says "why tf are we helping a kid" but is chided by Iida.
Ashido approaches Ochako and teases her, saying "hey Uraraka, tell me who's your crush!!" Ochako turns red and says "no one!!" Tsuyu interjects "that's not what your face says though!" In the background, Deku is trying to stop a fight from breaking out between Bakugou and Iida.
As the girls tease Ochako, Aoyama walks by and goes "ISN'T MY CAPE SO SHINY!??" Mineta then points at Yaoyorozu's boobs and says "boobs." Tokoyami is seen standing next to a tree and says, "A banquet of darkness."
Tsuyoshi looks at the students worriedly and doesn't believe these guys to actually be heroes. He notes that there's also a man on the floor in a sleeping bag and goes, "WHY IS HE SLEEPING?" and then Iida asks for permission to find the villains, and Aizawa agrees.
Tsuyoshi is more baffled that Aizawa is their teacher, but he goes along with the students since they're trying to help him find his ball anyway. Jirou uses her quirk to listen to any suspicious conversations in the nearby area, and she listens in on a group talking about a ball.
She tells everyone of their location, and Iida runs forward to try to stop the villain who has the ball. He finds that the villain is actually being apprehended by another larger villain that looks like Godzilla. Iida tries to stop him, but the Godzilla villain is too powerful.
Tsuyoshi gets scared of this giant dinosaur looking villain, and Bakugou zooms in a uses his Howitzer Impact on the dinosaur while saying "DIEEE!!" Tsuyoshi goes "did he just say 'die'?" But the dinosaur villain gets back up, but Todoroki comes in and blasts a huge wall of ice.
The dinosaur villain gets trapped in the ice, and Tsuyoshi looks at them and says "everyone is so strong!!" and right after, Deku asks Tsuyu to launch him into the air with her tongue. She gives him a boost, and Tsuyoshi asks Todoroki "What's Deku's quirk?"
Todoroki says "Midoriya's quirk is just like All Might, an extreme power!" Deku then smashes the Dinosaur villain and knocks him out. The dinosaur villain falls to the ground, and Mineta uses his mogimogi balls to capture all the villains within its stickiness.
The villains return the ball to Tsuyoshi, and he looks at Class A, saying "Wow, they're all so cool!" CHAPTER ENDS! The next chapter will be very long and will reveal the teams for the story! This Chapter 1 was also kind of like an introduction on what Class A can do.
