The 'Beako' meme refers to Beatrice, a key supporting character from the popular anime and light novel series 'Re:Zero - Starting Life in Another World.' Known for her distinct drill-shaped pigtails and her habit of ending sentences with 'kashira' (translated as 'in fact' or 'I suppose'), Beatrice became a fan favorite for her tsundere-like personality and interactions with the protagonist, Subaru. The meme typically uses her judgmental or smug expressions to dismiss opinions or assert dominance in a humorous, high-and-mighty fashion. It gained significant traction within the anime community as a versatile reaction image for situations involving stubbornness, dry wit, or undeniable truths.
