Yubi Yubi is closely associated with Inugami Korone, a Japanese VTuber known for turning the phrase into a memorable greeting and fan catchphrase. Short clips of it spread widely in anime and VTuber communities through highlight edits, remixes, compilations, and reaction posts. Its staying power comes from how fast and recognizable it is: the voice lands in under a second, but it instantly signals Korone's playful persona. Among anime-style catchphrases online, it fills a similar role to Tuturu as a brief, character-linked audio cue.
