Caren is presented here simply as a Vtuber introducing herself, and the clip circulates as a short fan soundbite rather than a song or a scene from a film. The word oshi comes from Japanese idol culture and means the performer you push and support most, which explains why the line works as both a greeting and a declaration of fandom. Shared on soundboards and in fan edits, it has become a handy shorthand for Vtuber culture, letting fans signal affection, start a stream themed video, or give a character an instant introduction without extra context.
