The name points to Sanae Dekomori, a character from the anime Love, Chunibyo and Other Delusions, known for her dramatic chunibyo persona and playful voice. Short character sounds like this sneeze are commonly clipped by fans and shared on soundboards, where they take on a second life outside the original show. Because the clip is under a second long, it is easy to drop into reaction videos, memes, and short-form edits without breaking the flow. Its charm comes from recognition: fans of the series hear the character instantly, while newcomers simply hear a cute, funny sneeze.
