Noa is a character from Shironeko Project, the Japanese mobile game also known as White Cat Project, and this clip comes from a collection of her voice lines for the game's Zekkai storyline, performed by Inori Minase. Fans lifted the short yurayura line because it captures Noa's gentle, sing-song personality in just two seconds, making it easy to share and reuse. It has since circulated on soundboards and in fan edits, where it works as a recognisable shorthand for Noa herself, even for viewers who have never played the game.
