The master of countless characters who took Japan’s random call scene by storm — Mysterious Dorai!
Now it’s your turn to join the Content Challenge using the Mysterious Dorai voice.

A creator who captivates audiences with flawless voice control and irresistible charm, Mysterious Dorai has officially arrived on Supertone.

Mysterious Dorai is widely known for accurately capturing the essence of various anime characters and delivering witty, entertaining Japanese live-call content that has amazed audiences time and again.

In particular, voice content featuring Satoru Gojo, Suguru Geto, and Ryomen Sukuna from Jujutsu Kaisen gained explosive popularity and became a hot topic.

With vivid realism and compelling storytelling, it feels as if these characters are speaking directly to you.
