Omaru Polka is a Japanese VTuber with Hololive, where fans often clip short greetings, reactions and catchphrases for soundboards and edits. Tadaima is the everyday Japanese phrase said when returning home, and Polka's bright delivery has made this one-second version a handy greeting for fan videos, streams and social posts. Because it is short, clear and instantly tied to her persona, it continues to circulate among Hololive fans as a welcoming opener rather than a punchline.
