Place it at the very start of an entrance sequence, before any dialogue from the arriving person. Follow it with Tuturu for a second anime greeting beat, or precede it with Teleport Sound Effect when the character appears suddenly instead of walking in normally.

This nine-second clip is a Japanese greeting built around yokoso, meaning welcome, spoken in a bright anime voice with a cheerful, theatrical lift. It feels warm, polite and playful, like a friendly entrance cue that instantly makes an arrival seem invited, celebrated and a little bit charming for listeners.
