What happened
On June 12, 2026, at 9 p.m. JST (Japan Standard Time), Sakayori Soma — a VTuber (a performer who streams as an animated avatar) under the Japanese agency Nijisanji — held his 3D debut stream on YouTube. The stream marked his first appearance as a fully animated 3D model rather than the usual 2D avatar. A 3D live (a stream where a virtual performer appears as a 3D model) is one of the biggest milestones in a VTuber's career, which is why these debuts draw large, emotionally invested audiences.
Why it is trending now
Sakayori Soma belongs to Speciale, a five-member Nijisanji unit, and his debut was the third stop in the unit's weekly 3D debut relay. The relay runs every Friday at 9 p.m. JST: Suzuna Nanase (May 29), Trout Nagisa (June 5), Sakayori Soma (June 12), Saotome Berry (June 19), and Kirara Tamako (June 26). Because the relay keeps a fresh debut coming each week, the unit's fans rally around the hashtag on a recurring schedule, which helped this stream climb the trends with more than 14,000 posts.
How fans reacted
After the stream ended, X filled with congratulations: "congrats," "that was amazing," "I cried." Fellow Speciale members posted some of the most-shared messages, including a tearful note saying his vision was too blurry to type steadily and that the unit "isn't fun without you." Viewers also singled out specific moments — an emotional exchange with a father character and a cover of "FLOWER" from the anime *Haganai* ("I Don't Have Many Friends") — and praised the look of the new 3D model.
What to watch next:
Two debuts remain in the Speciale relay: Saotome Berry on June 19 and Kirara Tamako on June 26, both at 9 p.m. JST. With one fresh 3D reveal landing each Friday, expect the unit's fandom to keep the hashtag busy through the end of June.
