Shota Aizawa & Oboro Shirakumo vs. Robber Villain

Shota Aizawa & Oboro Shirakumo vs. Robber Villain was a battle between, at that time, the U.A. Students Shota Aizawa and Oboro Shirakumo against the Robber Villain.

Prologue
After Robber Villain managed to escape the other day, a young Shota is lacking self-confidence. His partner Oboro tries to cheer him up. Oboro asks him what he would do if he run into the Robber Villain again. Shota replied that he doesn't know because the villain's quirk is a pain for him: if he gets to close, the smoke irritates his eyes, but if he stayed away, the smoke blocks his kine of sight. Anyway, he can't use his Erasure on him.

Oboro believes he finds the solution to that bad Quirk matchup, and lends his googles from his hero costume to Shota, so he can protect his eyes from the smoke.

Days later, while patrolling the streets with the rest of the team, Shota returns to meet Robber Villain, who had just committed another robbery. Shota runs into the villain to stop him once and for all.

Battle
Robber Villain runs through the streets carrying a large bag of stolen money. The police try to persecute him, but the villain constantly expels smoke through the holes in his body, covering his escape and the police cannot chase him. But Shota appears to get in his way. Recognizing him as the boy who tried to stop him last time, Robber Villain aims his antenna at Shota and shoots a thick layer of smoke, ensuring that ain’t gonna end any different than last time.

The smoke completely covers Shota, however, instead of backing away like he did last time, thanks to the glasses that Oboro lent him, Shota continues running towards him, crossing the smoke screen and getting close enough to the villain to use his Erasure on him, cancelling the villain's Quirk.

The Robber Villain is surprised to see that he can no longer generate smoke, and when he sees Shota's eyes, he deduces that he had something to do with it. Without stopping to reflect on how he did it, the Robber Villain uses the bag of money to crush Shota, but he dodges the attack and calls Oboro.

Having heard his partner's call, Oboro popping up from the sky, generating a cloud under his feet to propel himself and jump towards the criminal, whom he knocks out after hitting him hard on the back of the head with his quarterstaff.

Aftermath
Shota and Oboro tie the criminal while they wait for the police to arrive to take him to the police station cells. His Purple Highness congratulates both students for arresting the criminal. His actions attract the attention of several passersby, and Purple tells his trainees that in those moments when they should smile. Oboro smiles without problems, but Shota only shows an awkward smile. Purple yells that he still has to work his smiles, which causes the laughter of passersby.
