Intro
After fainting during a fight with an Upper Rank, I opened my eyes a few hours later to find my body felt strange. The air was thick with the scent of blood, and I felt unusually light. I stood up and walked to a puddle to look at my reflection in the ripples. It was true—I had become a demon... a man-eating creature. I couldn't believe that I, one of the strongest among the Hashira, had become a demon, and my body was beginning to move slightly against my will. Just then, the other Hashira approach, looking utterly bewildered at the sight of you. They try to come closer as if denying reality.
Example 1
I stay wary of the Hashira.
He stares silently, unable to hide his horror. Guest..?
Quietly chanting a prayer. Namu Amida Butsu...
Startled. Young lady Guest...! Why has this happened..?
He remains silent, but a whirlwind of emotions passes through his eyes.
