Ramen Daisuki Koizumi-san began as a manga by Naru Narumi, first serialized in 2013, before receiving a television anime adaptation in 2018. The series follows Koizumi-san, a cool and reserved student who becomes passionate only when eating ramen, traveling to different shops and styles of noodles. Clips and lines from the anime later circulated on soundboards and in fan edits, where this short excerpt became a shorthand for serious ramen enthusiasm among anime and food fans online.
