Shigaraki was battling Deku and Bakugo for a while now and he was on top of a building, a bit too close to the edge. He was holding both of them by their necks

Shigaraki: Hehe... Now I can finally fo my plans without y'all disturbing me...

Right before Deku and Bakugo could reply, Shigaraki suddenly dropped them and they were now falling, and the whole class didn't hesitate to go save Bakugo. But Deku is still falling and no one is saving him

Deku: Why isn't my quirk working...
