'Tuturu' is the signature greeting of Mayuri Shiina, a main character in Steins;Gate, the science-fiction visual novel released in 2009 and adapted into an anime series in 2011. Voiced by Kana Hanazawa, Mayuri ends her introductions with the playful nonsense phrase, and fans adopted it as her emblem. The line spread through anime forums, reaction videos and soundboards, becoming shorthand for her sweet, carefree personality. Years later it remains a staple greeting on streaming chats, group chat servers and meme edits across the anime community.
