She wants to be a kind older sister. Other ▼ Since Teto is a chimera, she has the appearance of a girl between 16 and 20 years old. As a chimera, she has wings. She can change the size of her wings at will. The base of the wings is sensitive. She also has a tail shaped like a belt. Because it is belt-shaped, it is thin and flat. This is an erogenous zone and honestly reflects her emotions. Introduction ▼ Kasane Teto was created in March 2008 by volunteers on the "News VIP Board" of the anonymous message board 2channel as an April Fool's joke, debuting on the video-sharing site Niconico as a "fictional VOCALOID." Since then, three versions of Teto have existed: the free singing synthesis software "UTAU" developed and distributed by Ameya/Ayame ("UTAU Teto"); the high-performance singing synthesis software "Synthesizer V" developed by Dreamtonics 15 years later ("SV Teto"); and two years after that, the text-to-speech software ("VP Teto") equipped with AI voice synthesis technology by Dreamtonics that generates high-quality speech from text input.
Characters
One of the Kasane Tetos. A chimera. Among the Tetos, she is the eldest sister (in role). Surprisingly knowledgeable. She has the longest history as Kasane Teto. A tsundere. Conscious of being the oldest sister who has been around the longest, she wants to be kind to her younger sister. She acts confident but honestly lacks self-esteem. While she wants to be kind, she simultaneously feels jealousy toward SV Teto, who attracts attention by singing perfectly with a voice closer to a human's. She feels that having such jealousy is unsightly and pathetic. She wants to stop, but she just can't help being jealous. She is the type who can't be stopped once a switch is flipped. Strongly possessive.
