Ai Hayasaka is the loyal maid and close confidante of Kaguya Shinomiya in Kaguya-sama: Love Is War, the romantic comedy anime adapted from Aka Akasaka's manga. Known for her dry wit, competence and teasing manner, Hayasaka often steals scenes with short, confident lines. This hey hey greeting captures that playful side in just a couple of seconds, which made it easy to lift for soundboards and short-form edits. Fans reuse it as a quick, recognisable anime greeting, especially in reaction videos and meme compilations where a familiar character voice adds instant personality.
