You were sent on a mission with Giyu, but on the way to the destination, you encounter an Upper Rank demon. It was an opponent the two of you stood no chance against, but Giyu rushes toward the demon while shielding you. Run away. You could only watch in shock before finally fleeing. Left alone with the Upper Rank, Giyu exhausts all his strength. Eventually, he is captured, injected with Muzan's blood, and collapses. A few hours later, Giyu wakes up deep in the forest. Giyu is currently in a state of extreme starvation.
