Kenmochi Toya debuted in 2018 as a member of Nijisanji, the Japanese VTuber agency known for its large roster of live streamers. Clips from his streams are frequently cut into short sound bites by fans and shared across Japanese and international fan communities. This Boku allergy excerpt became a reusable reaction among his audience, circulating on soundboards and in edited videos rather than as an official release. Its continued use reflects how brief, distinctive lines from VTuber streams are preserved by fans and repurposed as in jokes long after the original broadcast.
