The line is spoken by Raphael, the calm inner voice that guides Rimuru in That Time I Got Reincarnated as a Slime, a series built around Rimuru's second life in a fantasy world. Fans lifted the brief exchange into short soundboard and meme clips, where its deadpan denial travelled beyond anime edits into reaction videos and gaming moments. It endures because the wording is simple, instantly understandable without context, and perfectly suited to moments when a creator wants to brush off an awkward reveal with humour.
About this sound
Raphael's voice line from That Time I Got Reincarnated as a Slime says it is your imagination, used in memes to dismiss a theory or deny something obvious.
Delivered in Raphael's calm, flat and slightly detached voice, this short line lands like a quiet correction rather than an argument. The speaker does not raise her tone or rush the words, so the denial feels confident, almost amused, as if the other person has simply misunderstood something obvious. That deadpan delivery is what makes it funny: it can deflate an over-the-top reaction, turn a suspicious moment into a joke, or pretend that something clearly strange never happened. Listeners hear certainty, not anger, which lets the clip work as both a playful dismissal and a deadpan punchline in short videos.
