Ryomen Sukuna is a central antagonist in Jujutsu Kaisen, the manga series that began in 2018 and received a television anime adaptation in 2020. Short clips of his Japanese dialogue spread through anime edits, memes, and character-focused videos on social platforms. The “oi, oi” delivery remains useful because it is instantly brief, expressive, and easy to synchronize with cuts. Fans commonly associate it with Sukuna’s intimidating confidence, making the audio recognizable even when it appears outside footage from the series.
