Beatrice is a spirit character in Re:Zero, the anime adaptation that began in 2016, and I suppose is one of her most recognisable verbal habits, reflecting her proud, bookish manner. Fans clipped the line because it is instantly recognisable even without context, and it soon circulated on anime soundboards and in short-form edits. Its brevity makes it easy to drop into reaction videos, while its dry tone suits moments of reluctant agreement. That combination has kept it in regular use among Re:Zero fans and anime meme creators.
