Battle

 *  The details from the beginning of this battle are unknown. 

During the battle, Katsuki and Eijiro trade blows using their Quirks. Eijiro's hardened skin dampens Katsuki's explosions and then Eijiro cuts his cheek open with a punch. Katuski backs off, mulls over Eijiro's persistence and wonders how long his opponent can keep his hardening up.

Eijiro rushes Katsuki and tries to strike him with a flurry of punches. This puts Katsuki on the defensive and forces him to constantly dodge while losing ground. Katsuki fights back with his explosions until he finally manages to damage Eijiro. He surmises that Eijiro has been pushing his Quirk beyond its limits by keeping his body rock hard the entire fight.

Knowing that Eijiro's defensive will give at any moment, Katsuki strikes with a large explosion. Eijiro manages to block it, but Katsuki unleashes a barrage of explosions that force Eijiro to overuse his Quirk. Katsuki capitalizes on the opening and strikes Eijiro with one final explosion. Eijiro falls defeated and Midnight declares Katsuki Bakugo the winner.

Aftermath
Tetsutetsu is deeply disappointed with Eijiro's performance after cheering for him the entire time. Katsuki advances to the third round, and the final four are revealed to be Katsuki, Shoto, Tenya, and Fumikage.
