It seems like the best fit, but I’m not actually sure if that would apply either. The definition listed there is when a character talks directly to the audience, like in a Deadpool movie when he makes a joke as an aside, it seems to more apply to characters inside the story, not outside. I guess you can argue that the Narrator is considered a character in a story, but in my mind they’ve always seemed sort of nebulous and outside “the story” (with some exceptions to this). The Narrator is sort of always talking to the reader in a way (unless it’s a character specifically narrating the events to another character).
