Battle

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

Towards the end of the fight, Yuga and Ochaco make a break for the escape gate. Thirteen catches them with her Black Hole Quirk and pulls them closer. Ochaco and Yuga hang onto a railing for dear life as Thirteen inches closer.

Yuga tries sending his lasers pulsing through his costume to surprise Thirteen. Black Hole breaks it down along with Yuga's mask. Ochaco starts to panic and wonders what Izuku Midoriya would do in this situation. Yuga suddenly asks if Ochaco likes Izuku.

Ochaco is so embarrassed that she lets go of the railing. This surprises Thirteen, who stops using Black Hole in order to spare Ochaco. Ochaco finds herself in close quarters with her teacher and attacks with martial arts taught to her by the Battle Hero: Gunhead.

Using Gunhead Martial Arts, Ochaco tackles Thirteen to the ground. Thirteen tries to raise her hand, but Yuga propels himself onto it with his belly button laser. Ochaco handcuffs Thirteen and secures the victory for her team. Ochaco proves herself to be a Mini Battle Hero.

Aftermath
During the Quirk Training Camp, Shota Aizawa reveals that Team Uraraka & Aoyama barely passed by U.A. standards. They received extra focus during the camp but did not attend extra lessons, unlike the students who failed.

Anime and Manga Differences
In the manga adaptation of this battle, Thirteen explains the rules of the exam to them alone rather than Shota Aizawa doing it along with all the teachers. Ochaco and Yuga took the test at the same time as everyone else instead of going fifth. They finished just shortly before the exam ended.
