The sound is tied to Ichigo Kurosaki and his hollow form in Bleach, the anime and manga series following a teenager who becomes a Soul Reaper. When the hollow side surfaces, Ichigo's voice turns savage and inhuman, marking a shift from controlled fighter to something far more dangerous. Short clips of that transformation have long circulated among anime editors, who reuse the scream as shorthand for rage, corruption or unleashed power. Its raw, recognisable tone keeps it useful in fan edits, memes and reaction videos years after the original scenes aired.
