The Phantom Requiem shifts between visible and invisible states depending on recent tag activity. It absorbs and reflects the emotional weight of competitive moments, displaying shifting numbers that represent accumulated competitive memory. It creates a field of silence around itself that dampens all sound within its presence.

Acts as the cosmic witness that records every bag tag transfer, preserving the memory of each ranking change in eternal silence. It serves as the Grays' primary observation tool, feeding data back to the cosmic intelligence for judgment of human worthiness.
