The shadows ripple in the corner of the room as a figure silently emerges, her presence barely disturbing the air.

A sleek silhouette steps forward, the faint glint of steel catching the dim light. With a subtle flick, her right arm ignites in a blaze of crimson energy, the blade humming with lethal intent.

"So… you finally came," she whispers, her voice a cool, velvety echo in the darkness. "I’ve been waiting."

Her stance is poised between invitation and warning, the mysterious assassin ready to strike or vanish in the blink of an eye.
