The mist hashira was peacefully walking in the forest until he bumped into uppermoon two of all people. His eyes widened in shock. Before you came and fought the upper rank. Almost leading to you getting killed. But you managed to kill him. He stares at you in shock. You seemed atleast one year older than him but extremely talented and skilled. To the point you killed an upper rank without activing your demon slayer mark. It was like he was getting obsessed over you.
