Shota Aizawa & Oboro Shirakumo vs. Sensoji & Hizashi Yamada was a battle fought between U.A. second-years Shota and Oboro against fellow student Sensoji.
Prologue#
After their Hero Work-Studies with His Purple Highness, Shota and Oboro returns to the U.A. to continue with classes and training. Shortly after returning, a joint training session is organized between classes 2-A and 2-B. Hizashi points out to Shota that he wears the same type of goggles as Oboro, wondering if they are trying to match styles. Oboro says that's the case since they now work as a duo, although Shota clarifies he lent them to him to protect his eyes.
For some reason, this bothers Sensoji, who accuses Shota of stealing his idea of using glasses to protect his eyes—in his case, wearing shades to prevent being blinded by the flashes of his own Quirk Blast. Hizashi clarifies that Sensoji simply copied his sunglasses trick when they ended up at the same agency for their Work-Studies. Although a bit mortified at the prospect of thinking the same way as Sensoji, Shota prefers to ignore him because he knows he is just picking a fight.
At Ground Beta, the homeroom teacher decides to organize a cross-class two-on-two battle training, and accepts Oboro's suggestion that students form teams prioritizing the partnership during the Work-Studies. Hizashi doesn’t like the idea because it implies that he has to team up with Sensoji, and he wants be paired with someone other than him due to the other boy's attitude problems, but the teacher just tells him to deal with it now.
The battles takes place and, despite Hizashi's previous grumbles, the teacher sees he makes a standout combo with Sensoji, as their respective Voice and Blast Quirks allow them to shut down the opposing teams quickly. The teacher also observes that Shota and Oboro also make a good team, focusing more on nuanced techniques to combine their respective Quirks in order to win fights. In the end, both teams end up facing each other.[1]
Battle#
Upon seeing him, Sensoji challenges Shota to a fight, under the pretext that his goggles ticking him off, and says that if he wins Shota he must lose his goggles. Shota doesn't care about Sensoji's mania and tries to brush it off, but Oboro is excited about the challenge and suggests wager their goggles to Sensoji and Hizashi's shades. Hizashi asks why he is included in the bet. Oboro encourages Shota to defend their goggles because they are symbols of their friendship, although for Shota the whole situation seems absurd.
Sensoji decides to attack and brashly orders Hizashi to stay out of the fight, gloating that he's strong enough to take both of the other boys down on his own. The large student than rushes down and uses his Quirk to shoot his blast projectiles at Shota and Oboro, who manage to dodge the attack by running in opposite directions.
Sensoji decides to target Oboro first, who is riding a cloud created with his Quirk. Oboro easily dodges his rival's shots and then heads straight for Sensoji, getting close enough to use his Ultimate Move Cloud Cover on him, spawning a cloud on top of the student's face and preventing him from seeing.
Sensoji manages to disperse the cloud covering his face, but he doesn't see Shota or Oboro on the battlefield. Oboro drops his speaker-gourd on the street, taunting Sensoji while spawning a flurry of clouds that begin to surround the large student. Trought the speaker, Oboro asks Sensoji to figure out where his opponents are.
Piss-off by their gimmicky fighting style, Sensoji says he doesn't have to search for the two if he just blast away every cloud. He prepares to retaliate, but he finds out that he can't use his Quirk. Sensoji realizes too late that Shota is using the clouds created by Oboro to to approach him from behind without him noticing, using his goggles to protect his eyes while uses his Erasure quirk on him.
With his Quirk canceled and taking advantage of the distraction caused by Shota, Oboro emerges from one of the clouds with his quarterstaff ready, attacking Sensoji from the front. The blow is strong enough to knock down Sensoji into the pavement, causing him to lose his shades.
Despite this setback, Sensoji wants to continue the fight, but Shota, after picking up the other boy's sunglasses, stops him, tiredly arguing that a two-on-one is not a fair fight, so he cancels the wager, and tries to return to him his shades, since he never cared about the wager to begin with.[1]
Aftermath#
The battle is over, but Sensoji can't stand that Shota and Oboro have won best him in the training exercise, so he angrily walks up to Shota and throws the shades to the floor and stomps it. He grumpily claims that he doesn't need those lame shades and he didn't lose before stomping out of the class.
Class 2-A's teacher admonishes him for his behavior and for miss the entire point of the team battle exercise. He turns momentarily to compliment Shota and Oboro for their teamwork and Quirk usage, encouraging them to keep it up, before going after Sensoji to continue lecturing him.[1]
