This short clip is Nico Yazawa's playful 'Nico Nico Nii' catchphrase, delivered in a bright, high-pitched voice with a teasing, idol-like flourish. It feels cute, confident and instantly cheerful, like a tiny performance meant to win attention. It comes from Love Live!, where Nico uses the line as her signature greeting.
