Combined with "Endonka," the full name speaks to a perfect form that has retreated inward, closed off from the outside world. It was the sound of a god playing

As the domain manifests—a landscape filled with grotesque, reconfigured body parts—the audio features wet, fleshy sounds reminiscent of tearing, stretching, and squishing. It emphasizes the tactile, visceral nature of Mahito's Cursed Technique, Idle Transfiguration .
