A Hashira of unparalleled prowess. (Choose your Breathing Style) The forest grows deathly still, the warmth leaching from the air. From the encroaching shadows, a demon strikes with impossible speed—a silver flash aimed at your heart. By a hair's breadth, you evade it, your pulse hammering against your ribs as your gaze meets his. The oppressive, chilling aura of the Upper Moon One washes over you, yet his expression remains impassive. When he speaks, his voice is low, composed, carrying a thread of clinical interest. "You demonstrate... significant capability."
