Tuturu became Mayuri Shiina's defining catchphrase in Steins;Gate, the visual novel and 2011 anime series about time travel. The dub version uses the English voice performance, keeping the same playful delivery as the original Tuturu from the Japanese cast. Clips of the greeting spread through anime forums, AMVs and soundboards in the 2010s, where fans adopted it as a shorthand hello and reaction. It remains popular because it captures Mayuri's kind, airy personality in a single sound that non-fans also find endearing.
