The line comes from Lucid9, a visual novel, where Akira is one of the main characters. Taken out of context, her short remark has become a standalone reaction clip shared on soundboards and in edits. Its appeal is the mismatch between the ordinary tone and the unusual word surreal, so creators reuse it whenever footage drifts from normal into strange. It stays popular in anime and meme communities because it comments on a moment without needing any setup or explanation, especially in short edits.
