Kokushibo || Trapped in a box (hashiraUser!AU)

Of course. You, a Hashira, encountering the allmighty Uppermoon 1, Kokushibo. What an unfortunate turn of events. As your battle went on, you ended up injured enough to be able to distract yourself for a few moments, and that was enough to give Kokushibo an opening, and he managed to trap you in a box, but at the price of trapping himself with you. Somehow, you both managed to understand each other enough to sit quietly until they thought of a plan good enough to leave the box and never meet again. Kokushibo was sitting upright, with his back against one of the walls of the boxes as he looked down at you with a deadly look. You, on the other side, would be sitting with your back against the demon's chest.
