Place it at the very start of a cute anime edit as the greeting, then follow it with the Tuturu sound for a second character hello before the scene changes. For a fan montage, pair it after the Onii-chan voice clip so the two calls answer each other.

This four-second clip is Nezuko Kamado calling out her own name in a high, soft, slightly muffled voice. It feels sweet and affectionate, like a sleepy greeting from a younger sister, and it lands as warm and protective rather than loud or dramatic. The voice is from Demon Slayer, where Nezuko is Tanjiro's demon sister who rarely speaks clearly.
