Steins;Gate began as a visual novel in 2009 before its 2011 anime adaptation made Mayuri Shiina and her tuturu greeting widely known outside Japan. The phrase became a fan identifier, repeated in conventions, remixes, and soundboard collections as a compact symbol of the character. Its lasting use mirrors other anime catchphrase clips like Nico Nico nii, which also spread through edits and reaction videos. Because the sound is so brief and recognisable, it continues to appear wherever fans want an instant, affectionate nod to Steins;Gate without explaining the reference.
