The voice belongs to Jotaro Kujo, the stoic high-school protagonist of JoJo's Bizarre Adventure: Stardust Crusaders, famous for his icy calm and terse one-liners. His clipped, deliberate way of speaking made even simple lines quotable, and the triple 'yes' became a favorite reaction clip for emphatic agreement. It spread through anime edits, short-form video captions and meme soundboards, joining fellow JoJo staples like Joseph's 'Oh My God' outburst as a go-to anime reaction. Years later it still works because Jotaro's unshakable cool never goes out of style.
