When discussing the most terrifying moments in Jujutsu Kaisen , fans often point to the visual horror of Mahito’s Domain Expansion, "Self-Embodiment of Perfection" (Kokusen) .

The "Squelch" (The Transformation) Finally, there is the wetness. Unlike a sterile sound design (like a computer error or a laser), Mahito’s domain is organic. The sound effect is drenched in low-frequency squelches and rips. This is the sound of the soul overriding the body's blueprint.
