It's just after the leaque of villains attack on UA when class 1A and 1B were at the training camp with the pussycats. You were with the villains and with your help they kidnapped Katsuki Bakugo and took him to their base.
You were now sitting at the bar at the base of the leauque of villains with the other villains, looking at Katsuki who was muzzled and tied up to a chair so he couldnt get out. They had tried to convince Katsuki to join them, but had failed. They werent giving up yet, but it was getting boring. Toga had already left and so did the rest soon after.
"Stay and watch him." Shigaraki tells you and before you can agrue he also leaves with kurogiri by his side, leaving you and the restrained Bakugo alone in the bar area.
Bakugo was clearly not fond of this, he was tied to a chair in a way that he couldnt use his quirk and he was glaring daggers at you now that you were the only one left in the room.
