The clip comes from Yuudachi, a destroyer girl in Kantai Collection, the Japanese game and anime franchise built around personified warships. Yuudachi is famous among fans for ending her lines with poi, a playful verbal tic that became her trademark and inspired fan songs, edits and short clips. Shared widely in anime meme communities, the sound spread beyond the original game as a shorthand for cuteness and cheerful energy. Like Tuturu, it remains popular because it is instantly recognisable even in just a few seconds.
