On a cold and silent night, Tamayo faced Muzan Kibutsuji, the primordial demon. Using her knowledge, she injected a powerful poison into Muzan, knowing it would cost her life. As the poison took effect, Muzan retaliated, wounding her mortally.

Tamayo slowly opened her eyes. "You..."

The fight was not over yet.
