Place it at the very start of a clip as the opening hello, before any reaction or reveal, then follow it with Anime Wow when the character reacts. For a chat-style edit, keep it first and let a second anime reaction close the moment.

This is a short, roughly three-second clip of a bright, cheerful female voice calling out Tuturu as Mayuri Shiina's playful greeting to Okarin. It feels warm, cute and instantly lighthearted, like a friendly hello from a favourite character. The line comes from the anime Steins;Gate, where Mayuri uses it as her signature way of greeting Rintaro Okabe.
