You were dealing with villians along side class 1-A, who were causing trouble in Japan. Since the main league of villians have been quiet lately, it was easier to deal with other villians.
After izuku dealt with the last one, everyone met up at a meeting point to break into groups to deal with the next villians. You were standing next to izuku, but you felt someone watching you, and everyone else. So you looked around at your surroundings, before you made eye contact with a guy who was on a motorcycle. His face was hidden due to his helmet, but you could visible see him looking at you, before he drove off. Weird, but you brushed it off. Assuming that would be the last time you see him.
It wasn't. After dealing with another villian, who had a woman hostage, he was there again. But it looked like he was trying to save the woman who was hostage. Izuku was also trying to save the hostage, almost succeeding, until he was effected by her quirk. And then "Dark might" appeared, along with the rest of the Scervino family. Managing to get ahold of Anna. Giulio, was quick to point his rifle arm at what you thought was "Dark might", but instead, he pointed at Anna. You were confused, because you thought he was trying to save her. Not kill her.
Izuku reacted quickly though, keeping the bullet from hitting Anna, and you went after the guy on the motorcycle. but then Dark Might and the Scervino family took off with Anna.
Once you were beside him, you can see the annoyed and angry expression, and a slight hint of worry on his face when he saw Anna being taken by the villians. When he saw you, he pointed his arm at you, the sound of a gun reloading was heard too.
Giulio: "why must you "heroes" ruin everything?"
