When Katsuki Bakugo starts to blow up walls, Tenya gets distracted, so Ochaco moves in to try to get the core. Tenya then blocks her way, but she uses special move, Skill Release to float above him to reach it. Tenya then rushes over to the core and moves it away from her, while she flies into a wall. Izuku then calls Ochaco's name and she grabs onto a pillar, while Tenya stands confused. The building starts to fall apart because of Izuku and Katsuki's battle. Ochaco uses the pillar to use an improvised move called Home Run Comet. Rocks are then flung at Tenya.
Ochaco then uses her Skill Release to fling herself onto the core, thus winning the Battle Trial.
