Drive It Home, Iron Fist!!!.
After defeating Muscular, Midoriya carries Kota back to the camp and runs into Aizawa. Midoriya passes Kota over to him, as he has a message to deliver to everyone through Mandalay's telepathy. The teacher asks Midoriya to deliver a message from him as well. Mandalay delivers both messages: That Bakugo is one of the villains' targets and the students have permission to use their Quirks to defend themselves. Meanwhile, Tetsutetsu and Kendo find the source of a poisonous gas that is filling part of the forest: a villain named Mustard. The two work together to defeat Mustard and this results in the gas dissipating. Midoriya runs into Shoji while searching for Bakugo and learns that Tokoyami’s Quirk, Dark Shadow, is out of control.
