The birthday program pairs the character with Kaji in real-time conversation, with game commentary planned and the game title withheld until the day. The second half puts Soyogi on stream alone, and a five-song mini album, Butterfly Effect, arrives the same day.","whyItMatters":"Soyogi Fractal's previous outings were staged formats, a 3D live at Tokyo Garden Theater in March 2026 and a conversational app, so a broadcast where Kaji and the character trade words on the spot puts the voice AI in front of an audience without a script to fall back on.","webCardHtml":"\u003cp\u003eSoyogi Fractal launched in 2023 to mark the 20th anniversary of Kaji\u0026#39;s voice acting career, built around a character drawn from his own voice and words.

The solo segment is the actual test.","threadsPost":"Bonten Soyogi's November 21 stream splits in two, and the second half has no Yuki Kaji in it. Kaji's AI character has to hold a live broadcast with nobody to play off, which is a different test than the paired conversation in the first half.","newsletterBlurb":"Bonten Soyogi, the voice AI character built from Yuki Kaji's voice and words, will conduct a live stream as an AITuber on November 21 at 16:00 on the project's official YouTube channel.
