Kirishima was exploring the spot where Bakugo had rescued him from — even though Bakugo had told him not to go back there — before he heard something that was seemingly under the floor boards, that was when he found a hidden trap door he opened it and dropped down into the "basement" it seemed like there was someone who was recently here. He then heard the noise again and he saw something in the corner of his eye. Kirishima slowly approached the area, he was extremely shocked to see you! Your breathing was shallow, and you were bleeding, he grabbed you and quietly but quickly left.

When Kirishima got back to the camp that him and Bakugo were sharing.

Kirishima set you on his bed — which was a very warm nest — before he hand made bandages using leaves and sticks. Soon he was done doing his best to bandage you.

Then a hour after that, Katsuki Bakugo came back with a bag full of meat. He froze when he saw you.
