This sound is associated with Ryomen Sukuna from Jujutsu Kaisen, the manga by Gege Akutami and its anime adaptation that began in 2020. Online, Sukuna’s laugh spread through anime edits, power-scaling clips and villain compilations because it quickly signals arrogance, danger and total control. It remains popular in short-form video formats where creators need an instantly recognisable anime reaction. It is often used alongside other dramatic anime audio, including To be Continued (jojo), to heighten tension or underline an ominous reveal.
