My Hero Academia S3 Ep 16 - F2F Transformation

Season 3 Episode 16 Shiketsu High Lurking
The Ketsubutsu students lose track of Izuku and he hides behind some rubble with Ochaco. Ochaco tries to tag another one of his weak points and Izuku slaps away her ball. He reveals he knows she's probably from Shiketsu because Ochaco would have used her Quirk to save herself earlier. Camie reveals herself and attacks Izuku in the nude. Hanta and the real Ochaco arrive and force Camie to retreat after she tells Ochaco how much Izuku trusts her. Hanta wants to go after her but Izuku says her targets aren't visible because she's naked. Izuku tries to confirm both his classmates' identities by explaining that Camie had the ability to turn into Ochaco.
