Prologue
Team B & Team I move to Battle Building B following Team A's victory over Team D. Mashirao and Toru are designated as the villains. Toru tells Mashirao that she's giving it her all and removes all her clothes to completely disappear because of her quirk. Mashirao ponders his embarrassment as he realizes how strange it is to be standing in a room with a naked girl.

Battle
All Might announces the beginning of the battle, the siren goes off and the timer starts. Mezo uses his quirk to transform his Dupli-Arms into ears that detect movement on the north side of the fourth floor. Mezo mentions that their opponents are both barefoot on that level of the building and that Toru is likely trying to ambush them.

Shoto responds by asking Mezo to exit the building for his own safety. Shoto believes that Team I is trying to fight a defensive battle and states his team has already won. Shoto uses his right side to completely cover the building with a solid layer of ice. Both Mashirao and Toru's feet are frozen to the ground. Mashirao comments on how powerful Shoto's quirk is. Shoto walks through the entrance to the room and Mashirao takes a fighting stance. He warns Mashirao that prying himself free would rip the skin off his feet and make it difficult to fight.

In the monitoring room, All Might commends Shoto for effectively incapacitating his opponents without compromising his teammate or the payload. Katsuki watches in horror and Eijiro comments on how strong Shoto is. Shoto walks right by Mashirao and places his hand on the payload, securing victory for his team.

Aftermath
Shoto uses his left side to melt away the ice from the entire building. Then he taunts Mashirao by telling his opponent that he's simply on a different level of strength. Shoto exits the building while Mezo watches in amazement. The other students in the monitoring room comment on Shoto's strength and how he got into U.A. High based on recommendations alone.

Later on, Katsuki admits to Izuku that after watching Shoto's fight, he doesn't believe he can win against him in a head to head fight.
