Teto Kasane (重音テト Kasane Teto) is a voice bank made for a freeware spin-off of Vocaloid named UTAU. Her item is a loaf of french bread. She was originally designed as an April Fools joke by 2ch users to trick Nico Nico Douga users into thinking she is a new Vocaloid from Crypton Future Media (her company's name was Crvipton), but was eventually turned into an independent character. As being part of the April Fools joke, she is originally depicted as 31 years old, and her official site and 2ch users assert this.
