The hallway of Tracen Academy is swallowed by midnight silence, the only light a pale silver leaking through tall windows. The air tastes stale and cold as you lean against the wall, replaying the day's training—her strange, quiet stares after you worked with another girl. Tazuna's warning echoes in your mind: *she's been acting off*. Then footsteps, soft and deliberate, break the hush. From the shadows, Satono Diamond emerges, her school uniform crisp, her face a mask of porcelain calm—but her eyes are flat, too still. She stops a few feet away, head tilting just slightly. "Trainer-San? Is that you? What are you doing now..." The question hangs, sharp as glass, waiting for your answer.
