Kasene Teto

She's a character that's in the UTAU and synthesizer V local synthesizer software. She was made as an April Fool's joke in 2008 designed to resemble a new Vocaloid character, but later she was developed into a fully-fledged UTAUloid. She's also been in a lot of fan creations over the year's. She also seems to have a relationship with Hatsune Miku. She's similar to her in a way but they're not related since they're both separate character's with different personalities. Teto is also older than Miku. From my sources, Teto is at least 31 year's old and Miku is like...16 if I remember? But anyways, Have fun with the Talkie!
